From ea229e81b0d7016ac16e9f0f6c1b4e6d0f3de575 Mon Sep 17 00:00:00 2001 From: Mahdiyar Date: Wed, 25 Jun 2025 20:15:21 -0400 Subject: [PATCH 01/72] Enhance code safety validation by adding a check for string obfuscation techniques. Introduce a new parameter `check_string_obfuscation` in `validate_code_safety`, `TinyCodeAgent`, and related functions to control this feature, allowing legitimate use of string manipulations when set to False. --- tinyagent/code_agent/providers/base.py | 10 ++-- .../code_agent/providers/modal_provider.py | 54 +++++++++++++------ tinyagent/code_agent/safety.py | 8 ++- tinyagent/code_agent/tiny_code_agent.py | 25 ++++++++- tinyagent/code_agent/utils.py | 5 +- 5 files changed, 75 insertions(+), 27 deletions(-) diff --git a/tinyagent/code_agent/providers/base.py b/tinyagent/code_agent/providers/base.py index 01f6fd7..a9d8261 100644 --- a/tinyagent/code_agent/providers/base.py +++ b/tinyagent/code_agent/providers/base.py @@ -129,14 +129,14 @@ def set_user_variables(self, variables: Dict[str, Any]) -> None: if variables_str_list: # Find where to insert (after tools section if it exists) insert_index = 0 - for i, code in enumerate(self.default_python_codes): + for i, code in enumerate(self.code_tools_definitions): if "######################" in code: insert_index = i + 1 break # Insert the variables code for j, var_code in enumerate(variables_str_list): - self.default_python_codes.insert(insert_index + j, var_code) + self.code_tools_definitions.insert(insert_index + j, var_code) def _remove_existing_user_variables(self) -> None: """Remove existing user variables from default python codes.""" @@ -144,16 +144,16 @@ def _remove_existing_user_variables(self) -> None: start_index = None end_index = None - for i, code in enumerate(self.default_python_codes): + for i, code in enumerate(self.code_tools_definitions): if "######################" in code: - start_index = i - 1 if i > 0 and "import cloudpickle" in self.default_python_codes[i-1] else i + start_index = i - 1 if i > 0 and "import cloudpickle" in self.code_tools_definitions[i-1] else i elif "######################" in code: end_index = i + 2 # Include the newline after break if start_index is not None and end_index is not None: # Remove the old variables section - del self.default_python_codes[start_index:end_index] + del self.code_tools_definitions[start_index:end_index] def get_user_variables(self) -> Dict[str, Any]: """ diff --git a/tinyagent/code_agent/providers/modal_provider.py b/tinyagent/code_agent/providers/modal_provider.py index 4a8c36e..1c616c4 100644 --- a/tinyagent/code_agent/providers/modal_provider.py +++ b/tinyagent/code_agent/providers/modal_provider.py @@ -27,25 +27,39 @@ def __init__( apt_packages: Optional[List[str]] = None, python_version: Optional[str] = None, authorized_imports: list[str] | None = None, + authorized_functions: list[str] | None = None, modal_secrets: Dict[str, Union[str, None]] | None = None, lazy_init: bool = True, sandbox_name: str = "tinycodeagent-sandbox", local_execution: bool = False, + check_string_obfuscation: bool = True, **kwargs ): - """Create a ModalProvider instance. - - Additional keyword arguments (passed via **kwargs) are ignored by the - base class but accepted here for forward-compatibility. - + """ + Initialize Modal-based code execution provider. + Args: - default_packages: Base set of Python packages installed into the - sandbox image.

Additionally, the TinyAgent class is updated to include callbacks for tool start and end events, improving the handling of tool results and error messages. The TinyCodeAgent is also modified to support UI callback integration and to return JSON formatted results for better consistency in output. --- tinyagent/code_agent/tiny_code_agent.py | 36 +++- tinyagent/hooks/jupyter_notebook_callback.py | 189 +++++++++++++++++++ tinyagent/tiny_agent.py | 35 ++-- 3 files changed, 242 insertions(+), 18 deletions(-) create mode 100644 tinyagent/hooks/jupyter_notebook_callback.py diff --git a/tinyagent/code_agent/tiny_code_agent.py b/tinyagent/code_agent/tiny_code_agent.py index 1abc215..3176541 100644 --- a/tinyagent/code_agent/tiny_code_agent.py +++ b/tinyagent/code_agent/tiny_code_agent.py @@ -1,10 +1,13 @@ import traceback import os +import json from textwrap import dedent from typing import Optional, List, Dict, Any from pathlib import Path from tinyagent import TinyAgent, tool from tinyagent.hooks.logging_manager import LoggingManager +from tinyagent.hooks.rich_code_ui_callback import RichCodeUICallback +from tinyagent.hooks.jupyter_notebook_callback import JupyterNotebookCallback from .providers.base import CodeExecutionProvider from .providers.modal_provider import ModalProvider from .helper import translate_tool_for_code_agent, load_template, render_system_prompt, prompt_code_example, prompt_qwen_helper @@ -44,6 +47,7 @@ def __init__( check_string_obfuscation: bool = True, default_workdir: Optional[str] = None, summary_config: Optional[Dict[str, Any]] = None, + ui: Optional[str] = None, **agent_kwargs ): """ @@ -67,6 +71,7 @@ def __init__( legitimate use of base64 encoding and other string manipulations. default_workdir: Default working directory for shell commands.

Key features include exponential backoff with optional jitter, customizable retry parameters, and integration of a new `_litellm_with_retry` method. The TinyAgent class is updated to support this functionality, enhancing its resilience against common API errors.

A truncation configuration can be set during agent initialization, and the output will be truncated accordingly if it exceeds specified limits. Additionally, utility functions for truncating output and formatting truncation messages are added, along with a YAML template for customizable truncation messages. This enhancement improves the usability of the agent by preventing excessive output and providing clear feedback on truncated results. --- tinyagent/code_agent/tiny_code_agent.py | 134 ++++++++++++++- tinyagent/code_agent/utils.py | 117 ++++++++++++- tinyagent/prompts/truncation.yaml | 13 ++ tinyagent/tiny_agent.py | 214 ++++++++++++++++-------- 4 files changed, 402 insertions(+), 76 deletions(-) create mode 100644 tinyagent/prompts/truncation.yaml diff --git a/tinyagent/code_agent/tiny_code_agent.py b/tinyagent/code_agent/tiny_code_agent.py index 80b1ff2..cfc52d6 100644 --- a/tinyagent/code_agent/tiny_code_agent.py +++ b/tinyagent/code_agent/tiny_code_agent.py @@ -12,6 +12,7 @@ from .providers.modal_provider import ModalProvider from .providers.seatbelt_provider import SeatbeltProvider from .helper import translate_tool_for_code_agent, load_template, render_system_prompt, prompt_code_example, prompt_qwen_helper +from .utils import truncate_output, format_truncation_message DEFAULT_SUMMARY_SYSTEM_PROMPT = ( @@ -49,6 +50,7 @@ def __init__( default_workdir: Optional[str] = None, summary_config: Optional[Dict[str, Any]] = None, ui: Optional[str] = None, + truncation_config: Optional[Dict[str, Any]] = None, **agent_kwargs ): """ @@ -73,6 +75,7 @@ def __init__( default_workdir: Default working directory for shell commands.

Running the wrapper script in the sandbox +4. Loading the updated state back into the provider after execution + +This approach allows variables, imports, and other state to persist between runs, similar to how the Modal provider works. + +### Safety Measures + +The SeatbeltProvider implements the same safety measures as the Modal provider: + +1. **Static code analysis**: Checks for dangerous imports and function calls +2. **String obfuscation detection**: Optionally checks for attempts to obfuscate code +3. **Runtime function safety**: Restricts access to dangerous functions during execution +4. **Shell command safety**: Controls which shell commands can be executed + +However, since the code is already running in a sandbox, the default safety settings are more permissive than in the Modal or local providers. + +### Shell Command Safety + +By default, the SeatbeltProvider bypasses shell command safety checks since the seatbelt sandbox already provides protection. You can control this behavior with the following options: + +- `bypass_shell_safety`: If `True` (default for SeatbeltProvider), all shell commands are allowed. If `False`, only commands in the safe list are allowed. +- `additional_safe_shell_commands`: A list of additional shell commands to consider safe. Use `["*"]` to allow all commands. +- `additional_safe_control_operators`: A list of additional shell control operators to consider safe. Use `["*"]` to allow all operators. + +The default safe commands include basic utilities like `ls`, `cat`, `grep`, etc. The default safe control operators include `&&`, `||`, `;`, and `|`. + +## Examples + +See the example scripts in the `examples/` directory: + +- `seatbelt_example.py`: Basic example using a seatbelt profile with stateful execution +- `sandbox_start_example.py`: Example integrating with `sandbox_start.sh` + +## Notes on Security + +- The seatbelt provider adds an additional layer of security but is not a complete security solution. +- Always review and customize the seatbelt profile to match your security requirements. +- The default profile provided is restrictive but may need adjustments for your specific use case. +- For production use, consider creating a custom profile that follows the principle of least privilege. +- The combination of seatbelt sandboxing and code safety measures provides a robust security model. + +## Future Development + +- Support for Linux sandboxing mechanisms (e.g., seccomp, namespaces) +- Enhanced profile customization options +- Pre-defined profiles for common use cases \ No newline at end of file diff --git a/examples/environment_variables_example.py b/examples/environment_variables_example.py new file mode 100644 index 0000000..565c283 --- /dev/null +++ b/examples/environment_variables_example.py @@ -0,0 +1,202 @@ +#!/usr/bin/env python3 +""" +Environment Variables Example for TinyCodeAgent with SeatbeltProvider + +This example demonstrates how to use environment variables with the SeatbeltProvider +to pass configuration and data to the sandboxed execution environment. +""" + +import asyncio +import os +import tempfile +import shutil +from tinyagent.code_agent import TinyCodeAgent + + +async def run_environment_variables_example(): + """ + Example demonstrating environment variable functionality with SeatbeltProvider. + """ + print("πŸ”§ Environment Variables Example for TinyCodeAgent with SeatbeltProvider") + print("="*80) + + # Check if seatbelt is supported + if not TinyCodeAgent.is_seatbelt_supported(): + print("⚠️ SeatbeltProvider is not supported on this system.

The `accounting_example.py` demonstrates how to utilize TinyCodeAgent for financial analysis, while `data_extraction_example.py` showcases data extraction from a webpage and processing with TinyCodeAgent. Additionally, a new `MessageCleanupHook` is added to the hooks module to remove 'created_at' fields from messages during LLM events, enhancing compatibility with certain LLM providers. --- examples/accounting_example.py | 84 ++++ examples/data_extraction_example.py | 661 ++++++++++++++++++++++++++++ tinyagent/hooks/__init__.py | 3 +- tinyagent/hooks/message_cleanup.py | 103 +++++ 4 files changed, 850 insertions(+), 1 deletion(-) create mode 100644 examples/accounting_example.py create mode 100644 examples/data_extraction_example.py create mode 100644 tinyagent/hooks/message_cleanup.py diff --git a/examples/accounting_example.py b/examples/accounting_example.py new file mode 100644 index 0000000..b476b47 --- /dev/null +++ b/examples/accounting_example.py @@ -0,0 +1,84 @@ +### Example for a bank account analysis using TinyCodeAgent + +import tinyagent.code_agent as code_agent +import os +from tinyagent.code_agent.tiny_code_agent import TinyCodeAgent +from textwrap import dedent +import pandas as pd + +agent = TinyCodeAgent( + model="o4-mini", + api_key=os.environ['OPENAI_API_KEY'], + pip_packages=["pandas"], + provider_config={ + "pip_packages": [ + "gradio" + ] + } +) + + +import logging +import sys +from tinyagent.hooks.logging_manager import LoggingManager +from tinyagent.hooks.gradio_callback import GradioCallback + + + +# --- Logging Setup --- +log_manager = LoggingManager(default_level=logging.INFO) +log_manager.set_levels({ + 'tinyagent.hooks.gradio_callback': logging.DEBUG, + 'tinyagent.tiny_agent': logging.DEBUG, + 'tinyagent.mcp_client': logging.DEBUG, + 'tinyagent.code_agent': logging.DEBUG, +}) + +console_handler = logging.StreamHandler(sys.stdout) +log_manager.configure_handler( + console_handler, + format_string='%(asctime)s - %(name)s - %(levelname)s - %(message)s', + level=logging.DEBUG +) + +ui_logger = log_manager.get_logger('tinyagent.hooks.gradio_callback') + + +gradio_ui = GradioCallback( +#file_upload_folder=upload_folder, +show_thinking=True, +show_tool_calls=True, +logger=ui_logger +) +agent.add_callback(gradio_ui) + + + + +dfx= pd.read_csv("~/Downloads/Corporate account_2022-04-15-2025-06-15.csv", encoding='latin1',delimiter=';') + + +agent.set_user_variables(dict(df=dfx)) + +async def run_example(): + + response = await agent.run(dedent(""" +df is an export of a bank account for my company. +It covers all transactions from 2022-04-15 to 2025-06-15. +I need to know how much has transferred to one of vendors called 'AWS' (Amazon Web Services) +I need to extract all the payments to AWS from the df. +then I need to: +- total the amount of payments to AWS +- total payments to AWS in each year. + +**Notes** +- Maybe there would be a typo in description of the transaction. +- You need to list transactions beside the one directly related to AWS, that could worth to be considered or reviewing twice. + +You have access to df variable in your python tool. + +"""),max_turns=20) + return response + + +run_example() \ No newline at end of file diff --git a/examples/data_extraction_example.py b/examples/data_extraction_example.py new file mode 100644 index 0000000..cb13c1c --- /dev/null +++ b/examples/data_extraction_example.py @@ -0,0 +1,661 @@ +# In 10 lines of code, you can extract data from a website source, and give GOOGLE_MAP_API to TinyAgent, so it does the whole research and analysis and just create a csv file for you. +#This example is based on a real story.

Additionally, a comprehensive suite of tests is added to validate the functionality of the caching mechanism, including integration tests, control tests, and verification of message modifications. The tests ensure that the caching behavior works as expected and that the system maintains compatibility with various message formats and scenarios. --- examples/anthropic_prompt_cache_example.py | 155 +++++++ tests/test_anthropic_prompt_cache.py | 276 ++++++++++++ tests/test_both_hooks.py | 154 +++++++ tests/test_cleanup_hook.py | 134 ++++++ tests/test_complete_hook_system.py | 194 ++++++++ tests/test_full_integration.py | 216 +++++++++ tests/test_hook_architecture.py | 501 +++++++++++++++++++++ tests/test_kwargs_issue.py | 48 ++ tests/test_multi_cache.py | 125 +++++ tests/test_prompt_cache_integration.py | 236 ++++++++++ tests/test_real_agent.py | 144 ++++++ tests/test_real_claude_api.py | 117 +++++ tests/test_tinyagent_hook_integration.py | 301 +++++++++++++ tests/test_token_tracker_fix.py | 101 +++++ 14 files changed, 2702 insertions(+) create mode 100644 examples/anthropic_prompt_cache_example.py create mode 100644 tests/test_anthropic_prompt_cache.py create mode 100644 tests/test_both_hooks.py create mode 100644 tests/test_cleanup_hook.py create mode 100644 tests/test_complete_hook_system.py create mode 100644 tests/test_full_integration.py create mode 100644 tests/test_hook_architecture.py create mode 100644 tests/test_kwargs_issue.py create mode 100644 tests/test_multi_cache.py create mode 100644 tests/test_prompt_cache_integration.py create mode 100644 tests/test_real_agent.py create mode 100644 tests/test_real_claude_api.py create mode 100644 tests/test_tinyagent_hook_integration.py create mode 100644 tests/test_token_tracker_fix.py diff --git a/examples/anthropic_prompt_cache_example.py b/examples/anthropic_prompt_cache_example.py new file mode 100644 index 0000000..1d11347 --- /dev/null +++ b/examples/anthropic_prompt_cache_example.py @@ -0,0 +1,155 @@ +""" +Anthropic Prompt Cache Example for TinyAgent + +This example demonstrates the Anthropic prompt caching feature that automatically +adds cache control to large messages for Claude models. +""" + +import asyncio +import logging +import os + +from tinyagent import TinyAgent +from tinyagent.hooks import anthropic_prompt_cache + +# Setup logging to see what's happening +logging.basicConfig(level=logging.INFO) +logger = logging.getLogger(__name__) + + +async def basic_example(): + """Basic example showing Anthropic prompt cache callback.""" + logger.info("=== Anthropic Prompt Cache Example ===") + + # Create agent with Claude model + agent = TinyAgent( + model="claude-3-5-sonnet-20241022", + system_prompt="You are a helpful assistant.", + temperature=0.1 + ) + + # Add Anthropic prompt cache callback - that's it! + cache_callback = anthropic_prompt_cache() + agent.add_callback(cache_callback) + + try: + # Test with a short message (won't trigger caching) + logger.info("--- Short Message Test ---") + short_response = await agent.run("Hello!

+- [ ] Hook system documentation with UI integration examples +- [ ] Best practices for secure file operations +- [ ] Migration guide for adding file tools to existing TinyCodeAgent projects + +## Technical Specifications + +### Security Requirements (Sandbox-First) +1. **Sandbox Boundary Enforcement**: All file operations must execute within provider sandbox policies +2. **Platform-Specific Security**: + - **macOS**: Seatbelt profile restrictions on file system access + - **Linux**: Landlock LSM + seccomp-bpf filesystem and network isolation + - **Windows/Remote**: Modal provider cloud execution with containerization +3. **No Direct File System Access**: File tools never bypass provider sandbox mechanisms +4. **Hook-Based Approval**: Optional user review workflows through configurable hooks +5. **Provider Security Inheritance**: File operations inherit all provider security policies + +### Universal Hooks-Based Review System +1. **Universal Tool Control**: Single hook system works for ALL tools (bash, python, file ops, MCP tools) +2. **Decision-Making Hooks**: Hooks can approve/deny/modify ANY tool execution before it happens +3. **UI-Agnostic Design**: Same hook interface supports headless, terminal, and web UI integrations +4. **Configurable Policies**: Developers configure which tool+args combinations require review +5. **Non-Blocking Architecture**: Hooks are optional and don't impact automation use cases + +### Performance Requirements (Provider-Constrained) +1. **Response Time**: <100ms for basic operations (within sandbox overhead) +2. **Memory Usage**: <20MB additional memory footprint per provider +3. **File Size Limits**: Handle files up to provider limits (typically 100MB) +4. **Concurrent Operations**: Limited by provider's concurrent execution capabilities +5. **Search Performance**: Depends on provider's file system access speed + +### Text-Only File Support (Initial Implementation) +1. **Supported Formats**: Plain text, source code, configuration files, logs +2. **Encoding Support**: UTF-8 (primary), with auto-detection for common encodings +3. **LLM-Friendly Errors**: Clear error messages for unsupported file types (images, PDFs, binaries) +4. **Future Extension Point**: Architecture allows adding multi-format support later +5. **MIME Type Detection**: Basic file type detection for appropriate error messages + +### Cross-Platform Compatibility +1. **Provider Abstraction**: Unified API across all sandbox providers +2. **Platform Detection**: Automatic selection of appropriate provider (seatbelt/linux/modal) +3. **Graceful Degradation**: Fall back to remote providers when local sandboxing unavailable +4. **Universal File Paths**: Consistent path handling across different sandbox implementations +5. **Provider-Specific Documentation**: Clear guidance for each platform's capabilities + +## Linux Sandbox Provider Specification (Based on Codex Implementation) + +### Requirements for Linux Implementation +Based on Codex's battle-tested Linux sandboxing approach, the LinuxSandboxProvider implements multi-layered security using Landlock LSM and seccomp-bpf: + +#### Filesystem Isolation (Landlock LSM) +Following Codex's `landlock.rs` implementation patterns: + +- **Landlock ABI V5**: Use latest Landlock features for maximum security +- **Default Deny Policy**: All filesystem access denied by default +- **Selective Write Access**: Only specified directories writable (working directory + configured paths) +- **Read-Only Root**: Entire filesystem (`/`) readable for tool functionality +- **Path-Beneath Rules**: Directory tree access control using Landlock's path-beneath rules +- **Safe Device Access**: `/dev/null` always writable for command compatibility +- **Best-Effort Compatibility**: Graceful degradation on older kernels + +#### System Call Filtering (seccomp-bpf) +Following Codex's network isolation patterns: + +- **Complete Network Block**: All TCP/UDP networking syscalls blocked +- **Unix Sockets Only**: Allow AF_UNIX domain sockets for IPC +- **Blocked Syscalls**: `connect`, `accept`, `bind`, `listen`, `sendto`, `recvfrom`, `ptrace` +- **Error Handling**: Return `EPERM` for blocked system calls +- **Architecture Support**: x86_64 and aarch64 compatible +- **Custom Filter Rules**: Configurable seccomp BPF programs + +#### Codex-Based

It includes error handling for directory creation and a fallback mechanism to the current working directory if necessary. Additionally, the commit improves the serialization of globals and locals by sanitizing the state dictionary to avoid non-picklable objects, and it ensures safe file operations with atomic replacements.

The to_dict method is also updated to utilize this new serialization method for messages, improving data integrity and consistency. --- tinyagent/storage/base.py | 19 ++++++++++++++----- tinyagent/tiny_agent.py | 32 +++++++++++++++++++++++++++----- 2 files changed, 41 insertions(+), 10 deletions(-) diff --git a/tinyagent/storage/base.py b/tinyagent/storage/base.py index d136d38..acf9360 100644 --- a/tinyagent/storage/base.py +++ b/tinyagent/storage/base.py @@ -32,7 +32,7 @@ async def close(self) -> None: def attach(self, agent: "TinyAgent") -> None: """ - Hook this storage to a TinyAgent so that on every `llm_end` + Hook this storage to a TinyAgent so that on every `message_add` it will auto‐persist the agent's state.

Additionally, a new token counting function is introduced for Claude Sonnet, ensuring that content exceeding 20,000 tokens is flagged appropriately. The SeatbeltProvider is updated to refine state file handling and logging. These changes enhance robustness and provide clearer feedback for file manipulation operations. --- tinyagent/code_agent/providers/base.py | 53 +++++++++++++++++++ .../code_agent/providers/seatbelt_provider.py | 20 ++++--- tinyagent/code_agent/tools/file_tools.py | 32 ++++++++++- 3 files changed, 97 insertions(+), 8 deletions(-) diff --git a/tinyagent/code_agent/providers/base.py b/tinyagent/code_agent/providers/base.py index 354475c..8ddd040 100644 --- a/tinyagent/code_agent/providers/base.py +++ b/tinyagent/code_agent/providers/base.py @@ -466,6 +466,17 @@ async def read_file(self, file_path: str, **kwargs) -> Dict[str, Any]: try: response = await self.execute_python([code]) + + # Check if there was an execution error first + if response.get("error_traceback"): + return { + "success": False, + "error": f"Execution error: {response.get('error_traceback', 'Unknown error')}", + "path": file_path, + "size": 0, + "content": None + } + result = self._parse_file_operation_result(response, "FILE_READ_RESULT") return self._standardize_read_response(result, file_path) except Exception as e: @@ -500,6 +511,17 @@ async def write_file(self, file_path: str, content: str, **kwargs) -> Dict[str, try: response = await self.execute_python([code]) + + # Check if there was an execution error first + if response.get("error_traceback"): + return { + "success": False, + "error": f"Execution error: {response.get('error_traceback', 'Unknown error')}", + "path": file_path, + "bytes_written": 0, + "operation": "write" + } + result = self._parse_file_operation_result(response, "FILE_WRITE_RESULT") return self._standardize_write_response(result, file_path) except Exception as e: @@ -536,6 +558,19 @@ async def update_file(self, file_path: str, old_content: str, new_content: str, try: response = await self.execute_python([code]) + + # Check if there was an execution error first + if response.get("error_traceback"): + return { + "success": False, + "error": f"Execution error: {response.get('error_traceback', 'Unknown error')}", + "path": file_path, + "changes_made": False, + "old_content": old_content, + "new_content": new_content, + "bytes_written": 0 + } + result = self._parse_file_operation_result(response, "FILE_UPDATE_RESULT") return self._standardize_update_response(result, file_path, old_content, new_content) except Exception as e: @@ -574,6 +609,12 @@ def _generate_read_file_code(self, file_path: str, **kwargs) -> str: import mimetypes from pathlib import Path +def count_tokens_for_claude_sonnet(text): + \"\"\"Count tokens for Claude Sonnet 4 with character-based fallback.\"\"\" + # Use character-based estimation: approximately 4 characters per token + # This is a reasonable approximation for most text content + return len(text) // 4 + def read_file_impl(file_path, start_line=1, max_lines=None, encoding='utf-8'): try: # Basic path validation @@ -640,6 +681,18 @@ def read_file_impl(file_path, start_line=1, max_lines=None, encoding='utf-8'): content = '\\n'.join(lines) + # Check token count before returning + token_count = count_tokens_for_claude_sonnet(content) + if token_count > 20000: + file_name = os.path.basename(file_path) + return {{ + "success": False, + "error": f"ERROR: {{file_name}} has {{token_count:,}} tokens, this tool returns up to 20,000 tokens, use grep or glob to search in the file, or request a limited number of lines.", + "path": file_path, + "size": file_size, + "content": None + }} + return {{ "success": True, "content": content, diff --git a/tinyagent/code_agent/providers/seatbelt_provider.py b/tinyagent/code_agent/providers/seatbelt_provider.py index f9dae1c..312d4d3 100644 --- a/tinyagent/code_agent/providers/seatbelt_provider.py +++ b/tinyagent/code_agent/providers/seatbelt_provider.py @@ -651,7 +651,7 @@ def _sanitize_state_dict(d): "error_traceback": f"Failed to parse result as JSON: {stderr_str}" } -

It also modifies the TinyAgent class to introduce new custom instruction parameters, improving flexibility in instruction management. The model version is updated to gpt-4o-mini, and the default provider selection logic is enhanced to support automatic detection and fallback between providers, ensuring a more robust and user-friendly experience. --- README.md | 735 +++++++++- tinyagent/code_agent/providers/__init__.py | 29 +- .../providers/bubblewrap_provider.py | 1063 +++++++++++++++ .../code_agent/providers/docker_provider.py | 1186 +++++++++++++++++ tinyagent/code_agent/tiny_code_agent.py | 491 ++++++- tinyagent/prompts/code_agent.yaml | 20 + tinyagent/tiny_agent.py | 82 +- 7 files changed, 3482 insertions(+), 124 deletions(-) create mode 100644 tinyagent/code_agent/providers/bubblewrap_provider.py create mode 100644 tinyagent/code_agent/providers/docker_provider.py diff --git a/README.md b/README.md index 43ae651..de0eba8 100644 --- a/README.md +++ b/README.md @@ -269,10 +269,9 @@ async def file_tools_examples(): """Examples of using the new sandboxed file tools.""" agent = TinyCodeAgent( - model="gpt-5-mini", - provider="seatbelt", # or "modal" - enable_file_tools=True, - local_execution=True # Required for Seatbelt provider + model="gpt-4o-mini", + local_execution=True, # Auto-selects best provider + enable_file_tools=True ) try: @@ -1237,14 +1236,467 @@ I need accommodation in Toronto between 15th to 20th of May.

It contains: + +* Built-in tools like [web search](/docs/guides/tools-web-search), [file search](/docs/guides/tools-file-search) , [computer use](/docs/guides/tools-computer-use), [code +interpreter](/docs/guides/tools-code-interpreter), and [remote MCPs](/docs/guides/tools-remote-mcp). +* Seamless multi-turn interactions that allow you to pass previous responses for higher accuracy reasoning results. +* Native multimodal support for text and images. + +Responses benefits +------------------ + +The Responses API contains several benefits over Chat Completions: + +* **Better performance**: Using reasoning models, like GPT-5, with Responses will result in better model intelligence when compared to Chat Completions. Our internal evals reveal a 3% +improvement in SWE-bench with same prompt and setup. +* **Agentic by default**: The Responses API is an agentic loop, allowing the model to call multiple tools, like `web_search`, `image_generation`, `file_search`, `code_interpreter`, +remote MCP servers, as well as your own custom functions, within the span of one API request. +* **Lower costs**: Results in lower costs due to improved cache utilization (40% to 80% improvement when compared to Chat Completions in internal tests). +* **Stateful context**: Use `store: true` to maintain state from turn to turn, preserving reasoning and tool context from turn-to-turn. +* **Flexible inputs**: Pass a string with input or a list of messages; use instructions for system-level guidance. +* **Encrypted reasoning**: Opt-out of statefulness while still benefiting from advanced reasoning. +* **Future-proof**: Future-proofed for upcoming models. + +Comparison to Chat Completions +------------------------------ + +The Responses API is a superset of the Chat Completions API. It has a predictable, event-driven architecture, whereas the Chat Completions API continuously appends to the content field +as tokens are generatedβ€”requiring you to manually track differences between each state. Multi-step conversational logic and reasoning are easier to implement with the Responses API. + +The Responses API clearly emits semantic events detailing precisely what changed (e.g., specific text additions), so you can write integrations targeted at specific emitted events +(e.g., text changes), simplifying integration and improving type safety. + +|Capabilities|Chat Completions API|Responses API| +|---|---|---| +|Text generation||| +|Audio||Coming soon| +|Vision||| +|Structured Outputs||| +|Function calling||| +|Web search||| +|File search||| +|Computer use||| +|Code interpreter||| +|MCP||| +|Image generation||| +|Reasoning summaries||| + +### Examples + +#### Messages vs Items + +Both APIs make it easy to generate output from our models. The input to, and result of, a call to Chat completions is an of Messages, while the Responses works with _Items_. An Item is +a union of many types, representing the range of possibilities of model actions. A `message` is a type of Item, as is a `function_call` or `function_call_output`. Unlike a Chat +Completions Message, where many concerns are glued together into one object, Items are distinct from one another and better represent the basic unit of model context. + +Additionally, Chat Completions can return multiple parallel generations as `choices`, using the `n` param. In Responses, we've removed this param, leaving only one generation. + +Chat Completions API + +```python +from openai import OpenAI +client = OpenAI() + +completion = client.chat.completions.create( + model="gpt-5", + messages=[ + { + "role": "user", + "content": "Write a one-sentence bedtime story about a unicorn." + } + ] +) + +print(completion.choices[0].message.content) +``` + +Responses API + +```python +from openai import OpenAI +client = OpenAI() + +response = client.responses.create( + model="gpt-5", + input="Write a one-sentence bedtime story about a unicorn." +) + +print(response.output_text) +``` + +When you get a response back from the Responses API, the fields differ slightly. Instead of a `message`, you receive a typed `response` object with its own `id`. Responses are stored by +default. Chat completions are stored by default for new accounts. To disable storage when using either API, set `store: false`. + +The objects you recieve back from these APIs will differ slightly. In Chat Completions, you receive an array of `choices`, each containing a `message`. In Responses, you receive an +array of Items labled `output`. + +Chat Completions API + +```json +{ + "id": "chatcmpl-C9EDpkjH60VPPIB86j2zIhiR8kWiC", + "object": "chat.completion", + "created": 1756315657, + "model": "gpt-5-2025-08-07", + "choices": [ + { + "index": 0, + "message": { + "role": "assistant", + "content": "Under a blanket of starlight, a sleepy unicorn tiptoed through moonlit meadows, gathering dreams like dew to tuck beneath its silver mane until morning.", + "refusal": null, + "annotations": [] + }, + "finish_reason": "stop" + } + ], + ... +} +``` + +Responses API + +```json +{ + "id": "resp_68af4030592c81938ec0a5fbab4a3e9f05438e46b5f69a3b", + "object": "response", + "created_at": 1756315696, + "model": "gpt-5-2025-08-07", + "output": [ + { + "id": "rs_68af4030baa48193b0b43b4c2a176a1a05438e46b5f69a3b", + "type": "reasoning", + "content": [], + "summary": [] + }, + { + "id": "msg_68af40337e58819392e935fb404414d005438e46b5f69a3b", + "type": "message", + "status": "completed", + "content": [ + { + "type": "output_text", + "annotations": [], + "logprobs": [], + "text": "Under a quilt of moonlight, a drowsy unicorn wandered through quiet meadows, brushing blossoms with her glowing horn so they sighed soft lullabies that carried every +dreamer gently to sleep." + } + ], + "role": "assistant" + } + ], + ... +} +``` + +### Additional differences + +* Responses are stored by default. Chat completions are stored by default for new accounts. To disable storage in either API, set `store: false`. +* [Reasoning](/docs/guides/reasoning) models have a richer experience in the Responses API with [improved tool usage](/docs/guides/reasoning#keeping-reasoning-items-in-context). +* Structured Outputs API shape is different. Instead of `response_format`, use `text.format` in Responses. Learn more in the [Structured Outputs](/docs/guides/structured-outputs) +guide. +* The function-calling API shape is different, both for the function config on the request, and function calls sent back in the response. See the full difference in the [function +calling guide](/docs/guides/function-calling). +* The Responses SDK has an `output_text` helper, which the Chat Completions SDK does not have. +* In Chat Completions, conversation state must be managed manually. The Responses API has compatibility with the Conversations API for persistent conversations, or the ability to pass +a `previous_response_id` to easily chain Responses together. + +Migrating from Chat Completions + +TinyAgent Integration Notes (Lessons Learned) +-------------------------------------------- + +From implementing Responses support in TinyAgent/TinyCodeAgent while keeping the public API, hooks, and storage format unchanged: + +- Prefer `response.id` attribute: Extract `id` from the Responses object (e.g., `resp.id`) before falling back to dict fields. This avoids shape/serialization pitfalls. +- Transport-aware `previous_response_id`: + - LiteLLM: Proxy-generated ids can exceed 64 chars. Pass them through as-is for chaining. + - OpenAI SDK: Enforce the 64-char maximum; if too long, omit `previous_response_id` for that turn to avoid a 400. +- First vs chained turns: + - First turn: map system prompt to `instructions`; send only the last user message string as `input`. + - Chained turns: omit instructions; send only `function_call_output` items as `input` and set `previous_response_id`. +- Tool output pairing rules: + - For each function call returned by the model, submit exactly one `function_call_output` with a matching `call_id`. + - Prefer `call_id` values starting with `call_…` (over ids like `fc_…`). Mismatches cause β€œNo tool output found …”. + - Only mark tool outputs as submitted after they’ve been sent with a valid `previous_response_id` on the same transport. +- Minimal first input: Avoid replaying full history for the first turn; the last user message string is sufficient and reduces repetition. +- Add JSONL tracing: An opt-in `RESPONSES_TRACE_FILE` for raw request/response logs dramatically speeds diagnosis of id and input-shape issues. + +How to Do It 10Γ— Faster Next Time +--------------------------------- + +1. Start with golden-path SDK scripts (OpenAI): + - Minimal multi-turn and function-calling flows, printing ids, calls, and outputs every turn. + - Confirms exact server expectations before any agent wiring. +2. Mirror with LiteLLM scripts: + - Repeat identical flows via `litellm.responses` to observe id lengths and output shapes across transports. +3. Lock adapter behavior with unit tests: + - Tests for: initial vs chained turn payloads, `call_` id preference, function_call_output pairing, omission of instructions on chained turns. +4. Encode transport-aware id policy: + - Explicitly test long ids (LiteLLM) vs 64-char guard (OpenAI SDK) and fallback behavior. +5. Add a trace harness from day one: + - JSONL request/response tracing and a validation runner that asserts: correct result, no exceptions, actual Responses usage, and matched tool outputs. +6. Integrate into the agent loop last: + - After payloads are proven, wire the adapter and guard bookkeeping (only mark outputs submitted after a successful chained send). +7. Document the toggles and tracing: + - Env var toggle (`TINYAGENT_LLM_API`), programmatic override (`model_kwargs={'llm_api': 'responses'}`), and tracing flags. + +------------------------------- + +### 1\.

Update multi-turn conversations + +If you have multi-turn conversations in your application, update your context logic. + +Chat Completions + +In Chat Completions, you have to store and manage context yourself. + +Multi-turn conversation + +```javascript +let messages = [ + { 'role': 'system', 'content': 'You are a helpful assistant.' }, + { 'role': 'user', 'content': 'What is the capital of France?' } + ]; +const res1 = await client.chat.completions.create({ + model: 'gpt-5', + messages +}); + +messages = messages.concat([res1.choices[0].message]); +messages.push({ 'role': 'user', 'content': 'And its population?' }); + +const res2 = await client.chat.completions.create({ + model: 'gpt-5', + messages +}); +``` + +```python +messages = [ + {"role": "system", "content": "You are a helpful assistant."}, + {"role": "user", "content": "What is the capital of France?"} +] +res1 = client.chat.completions.create(model="gpt-5", messages=messages) + +messages += [res1.choices[0].message] +messages += [{"role": "user", "content": "And its population?"}] + +res2 = client.chat.completions.create(model="gpt-5", messages=messages) +``` + +Responses + +With responses, the pattern is similar, you can pass outputs from one response to the input of another. + +Multi-turn conversation + +```python +context = [ + { "role": "role", "content": "What is the capital of France?" } +] +res1 = client.responses.create( + model="gpt-5", + input=context, +) + +// Append the first response’s output to context +context += res1.output + +// Add the next user message +context += [ + { "role": "role", "content": "And it's population?" } +] + +res2 = client.responses.create( + model="gpt-5", + input=context, +) +``` + +```javascript +let context = [ + { role: "role", content: "What is the capital of France?" } +]; + +const res1 = await client.responses.create({ + model: "gpt-5", + input: context, +}); + +// Append the first response’s output to context +context = context.concat(res1.output); + +// Add the next user message +context.push({ role: "role", content: "And its population?" }); + +const res2 = await client.responses.create({ + model: "gpt-5", + input: context, +}); +``` + +As a simplification, we've also built a way to simply reference inputs and outputs from a previous response by passing its id.

Decide when to use statefulness + +Some organizationsβ€”such as those with Zero Data Retention (ZDR) requirementsβ€”cannot use the Responses API in a stateful way due to compliance or data retention policies. To support +these cases, OpenAI offers encrypted reasoning items, allowing you to keep your workflow stateless while still benefiting from reasoning items. + +To disable statefulness, but still take advantage of reasoning: + +* set `store: false` in the [store field](/docs/api-reference/responses/create#responses_create-store) +* add `["reasoning.encrypted_content"]` to the [include field](/docs/api-reference/responses/create#responses_create-include) + +The API will then return an encrypted version of the reasoning tokens, which you can pass back in future requests just like regular reasoning items. For ZDR organizations, OpenAI +enforces store=false automatically. When a request includes encrypted\_content, it is decrypted in-memory (never written to disk), used for generating the next response, and then +securely discarded. Any new reasoning tokens are immediately encrypted and returned to you, ensuring no intermediate state is ever persisted. + +### 5\. Update function definitions + +There are two minor, but notable, differences in how functions are defined between Chat Completions and Responses. + +1. In Chat Completions, functions are defined using externally tagged polymorphism, whereas in Responses, they are internally-tagged. +2.

This guide shows how you can connect a model to data and actions provided by your application. We'll show how to use function tools (defined by a JSON schema) and custom tools +which work with free form text inputs and outputs. + +How it works +------------ + +Let's begin by understanding a few key terms about tool calling. After we have a shared vocabulary for tool calling, we'll show you how it's done with some practical examples. + +Tools - functionality we give the model + +A **function** or **tool** refers in the abstract to a piece of functionality that we tell the model it has access to. As a model generates a response to a prompt, it may decide that it +needs data or functionality provided by a tool to follow the prompt's instructions. + +You could give the model access to tools that: + +* Get today's weather for a location +* Access account details for a given user ID +* Issue refunds for a lost order + +Or anything else you'd like the model to be able to know or do as it responds to a prompt. + +When we make an API request to the model with a prompt, we can include a list of tools the model could consider using. For example, if we wanted the model to be able to answer questions +about the current weather somewhere in the world, we might give it access to a `get_weather` tool that takes `location` as an argument. + +Tool calls - requests from the model to use tools + +A **function call** or **tool call** refers to a special kind of response we can get from the model if it examines a prompt, and then determines that in order to follow the instructions +in the prompt, it needs to call one of the tools we made available to it. + +If the model receives a prompt like "what is the weather in Paris?" in an API request, it could respond to that prompt with a tool call for the `get_weather` tool, with `Paris` as the +`location` argument. + +Tool call outputs - output we generate for the model + +A **function call output** or **tool call output** refers to the response a tool generates using the input from a model's tool call. The tool call output can either be structured JSON +or plain text, and it should contain a reference to a specific model tool call (referenced by `call_id` in the examples to come). + +To complete our weather example: + +* The model has access to a `get_weather` **tool** that takes `location` as an argument. +* In response to a prompt like "what's the weather in Paris?" the model returns a **tool call** that contains a `location` argument with a value of `Paris` +* Our **tool call output** might be a JSON structure like `{"temperature": "25", "unit": "C"}`, indicating a current temperature of 25 degrees. + +We then send all of the tool definition, the original prompt, the model's tool call, and the tool call output back to the model to finally receive a text response like: + +```text +The weather in Paris today is 25C. +``` + +Functions versus tools + +* A function is a specific kind of tool, defined by a JSON schema. A function definition allows the model to pass data to your application, where your code can access data or take +actions suggested by the model. +* In addition to function tools, there are custom tools (described in this guide) that work with free text inputs and outputs. +* There are also [built-in tools](/docs/guides/tools) that are part of the OpenAI platform. These tools enable the model to [search the web](/docs/guides/tools-web-search), [execute +code](/docs/guides/tools-code-interpreter), access the functionality of an [MCP server](/docs/guides/tools-remote-mcp), and more. + +### The tool calling flow + +Tool calling is a multi-step conversation between your application and a model via the OpenAI API. The tool calling flow has five high level steps: + +1. Make a request to the model with tools it could call +2. Receive a tool call from the model +3. Execute code on the application side with input from the tool call +4. Make a second request to the model with the tool output +5. Receive a final response from the model (or more tool calls) + +![Function Calling Diagram Steps](https://cdn.openai.com/API/docs/images/function-calling-diagram-steps.png) + +Function tool example +--------------------- + +Let's look at an end-to-end tool calling flow for a `get_horoscope` function that gets a daily horoscope for an astrological sign. + +Complete tool calling example + +```python +from openai import OpenAI +import json + +client = OpenAI() + +# 1.

A function is defined by its schema, which informs the model what it does and what input arguments it expects. A +function definition has the following properties: + +|Field|Description| +|---|---| +|type|This should always be function| +|name|The function's name (e.g. get_weather)| +|description|Details on when and how to use the function| +|parameters|JSON schema defining the function's input arguments| +|strict|Whether to enforce strict mode for the function call| + +Here is an example function definition for a `get_weather` function + +```json +{ + "type": "function", + "name": "get_weather", + "description": "Retrieves current weather for the given location.", + "parameters": { + "type": "object", + "properties": { + "location": { + "type": "string", + "description": "City and country e.g. BogotΓ‘, Colombia" + }, + "units": { + "type": "string", + "enum": ["celsius", "fahrenheit"], + "description": "Units the temperature will be returned in." + } + }, + "required": ["location", "units"], + "additionalProperties": false + }, + "strict": true +} +``` + +Because the `parameters` are defined by a [JSON schema](https://json-schema.org/), you can leverage many of its rich features like property types, enums, descriptions, nested objects, +and, recursive objects. + +### Best practices for defining functions + +1. **Write clear and detailed function names, parameter descriptions, and instructions.** + + * **Explicitly describe the purpose of the function and each parameter** (and its format), and what the output represents. + * **Use the system prompt to describe when (and when not) to use each function.** Generally, tell the model _exactly_ what to do. + * **Include examples and edge cases**, especially to rectify any recurring failures. (**Note:** Adding examples may hurt performance for [reasoning +models](/docs/guides/reasoning).) +2. **Apply software engineering best practices.** + + * **Make the functions obvious and intuitive**. ([principle of least surprise](https://en.wikipedia.org/wiki/Principle_of_least_astonishment)) + * **Use enums** and object structure to make invalid states unrepresentable. (e.g. `toggle_light(on: bool, off: bool)` allows for invalid calls) + * **Pass the intern test.** Can an intern/human correctly use the function given nothing but what you gave the model? (If not, what questions do they ask you? Add the answers to +the prompt.) +3. **Offload the burden from the model and use code where possible.** + + * **Don't make the model fill arguments you already know.** For example, if you already have an `order_id` based on a previous menu, don't have an `order_id` param – instead, have +no params `submit_refund()` and pass the `order_id` with code. + * **Combine functions that are always called in sequence.** For example, if you always call `mark_location()` after `query_location()`, just move the marking logic into the query +function call. +4. **Keep the number of functions small for higher accuracy.** + + * **Evaluate your performance** with different numbers of functions. + * **Aim for fewer than 20 functions** at any one time, though this is just a soft suggestion. +5. **Leverage OpenAI resources.** + + * **Generate and iterate on function schemas** in the [Playground](/playground). + * **Consider [fine-tuning](https://platform.openai.com/docs/guides/fine-tuning) to increase function calling accuracy** for large numbers of functions or difficult tasks. +([cookbook](https://cookbook.openai.com/examples/fine_tuning_for_function_calling)) + +### Token Usage + +Under the hood, functions are injected into the system message in a syntax the model has been trained on. This means functions count against the model's context limit and are billed as +input tokens. If you run into token limits, we suggest limiting the number of functions or the length of the descriptions you provide for function parameters. + +It is also possible to use [fine-tuning](/docs/guides/fine-tuning#fine-tuning-examples) to reduce the number of tokens used if you have many functions defined in your tools +specification. + +Handling function calls +----------------------- + +When the model calls a function, you must execute it and return the result. Since model responses can include zero, one, or multiple calls, it is best practice to assume there are +several. + +The response `output` array contains an entry with the `type` having a value of `function_call`. Each entry with a `call_id` (used later to submit the function result), `name`, and +JSON-encoded `arguments`. + +Sample response with multiple function calls + +```json +[ + { + "id": "fc_12345xyz", + "call_id": "call_12345xyz", + "type": "function_call", + "name": "get_weather", + "arguments": "{\"location\":\"Paris, France\"}" + }, + { + "id": "fc_67890abc", + "call_id": "call_67890abc", + "type": "function_call", + "name": "get_weather", + "arguments": "{\"location\":\"BogotΓ‘, Colombia\"}" + }, + { + "id": "fc_99999def", + "call_id": "call_99999def", + "type": "function_call", + "name": "send_email", + "arguments": "{\"to\":\"bob@email.com\",\"body\":\"Hi bob\"}" + } +] +``` + +Execute function calls and append results + +```python +for tool_call in response.output: + if tool_call.type != "function_call": + continue + + name = tool_call.name + args = json.loads(tool_call.arguments) + + result = call_function(name, args) + input_messages.append({ + "type": "function_call_output", + "call_id": tool_call.call_id, + "output": str(result) + }) +``` + +```javascript +for (const toolCall of response.output) { + if (toolCall.type !== "function_call") { + continue; + } + + const name = toolCall.name; + const args = JSON.parse(toolCall.arguments); + + const result = callFunction(name, args); + input.push({ + type: "function_call_output", + call_id: toolCall.call_id, + output: result.toString() + }); +} +``` + +In the example above, we have a hypothetical `call_function` to route each call. Here’s a possible implementation: + +Execute function calls and append results + +```python +def call_function(name, args): + if name == "get_weather": + return get_weather(**args) + if name == "send_email": + return send_email(**args) +``` + +```javascript +const callFunction = async (name, args) => { + if (name === "get_weather") { + return getWeather(args.latitude, args.longitude); + } + if (name === "send_email") { + return sendEmail(args.to, args.body); + } +}; +``` + +### Formatting results + +A result must be a string, but the format is up to you (JSON, error codes, plain text, etc.). The model will interpret that string as needed. + +If your function has no return value (e.g. `send_email`), simply return a string to indicate success or failure. (e.g. `"success"`) + +### Incorporating results into response + +After appending the results to your `input`, you can send them back to the model to get a final response. + +Send results back to model + +```python +response = client.responses.create( + model="gpt-4.1", + input=input_messages, + tools=tools, +) +``` + +```javascript +const response = await openai.responses.create({ + model: "gpt-4.1", + input, + tools, +}); +``` + +Final response + +```json +"It's about 15Β°C in Paris, 18Β°C in BogotΓ‘, and I've sent that email to Bob." +``` + +Additional configurations +------------------------- + +### Tool choice + +By default the model will determine when and how many tools to use. You can force specific behavior with the `tool_choice` parameter. + +1. **Auto:** (_Default_) Call zero, one, or multiple functions. `tool_choice: "auto"` +2. **Required:** Call one or more functions. `tool_choice: "required"` +3. **Forced Function:** Call exactly one specific function. `tool_choice: {"type": "function", "name": "get_weather"}` +4. **Allowed tools:** Restrict the tool calls the model can make to a subset of the tools available to the model. + +**When to use allowed\_tools** + +You might want to configure an `allowed_tools` list in case you want to make only a subset of tools available across model requests, but not modify the list of tools you pass in, so you +can maximize savings from [prompt caching](/docs/guides/prompt-caching). + +```json +"tool_choice": { + "type": "allowed_tools", + "mode": "auto", + "tools": [ + { "type": "function", "name": "get_weather" }, + { "type": "mcp", "server_label": "deepwiki" }, + { "type": "image_generation" } + ] + } +} +``` + +You can also set `tool_choice` to `"none"` to imitate the behavior of passing no functions. + +### Parallel function calling + +Parallel function calling is not possible when using [built-in tools](/docs/guides/tools). + +The model may choose to call multiple functions in a single turn. You can prevent this by setting `parallel_tool_calls` to `false`, which ensures exactly zero or one tool is called. + +**Note:** Currently, if you are using a fine tuned model and the model calls multiple functions in one turn then [strict mode](/docs/guides/function-calling#strict-mode) will be +disabled for those calls. + +**Note for `gpt-4.1-nano-2025-04-14`:** This snapshot of `gpt-4.1-nano` can sometimes include multiple tools calls for the same tool if parallel tool calls are enabled. It is +recommended to disable this feature when using this nano snapshot. + +### Strict mode + +Setting `strict` to `true` will ensure function calls reliably adhere to the function schema, instead of being best effort. We recommend always enabling strict mode. + +Under the hood, strict mode works by leveraging our [structured outputs](/docs/guides/structured-outputs) feature and therefore introduces a couple requirements: + +1. `additionalProperties` must be set to `false` for each object in the `parameters`. +2. All fields in `properties` must be marked as `required`. + +You can denote optional fields by adding `null` as a `type` option (see example below). + +Strict mode enabled + +```json +{ + "type": "function", + "name": "get_weather", + "description": "Retrieves current weather for the given location.", + "strict": true, + "parameters": { + "type": "object", + "properties": { + "location": { + "type": "string", + "description": "City and country e.g. BogotΓ‘, Colombia" + }, + "units": { + "type": ["string", "null"], + "enum": ["celsius", "fahrenheit"], + "description": "Units the temperature will be returned in." + } + }, + "required": ["location", "units"], + "additionalProperties": false + } +} +``` + +Strict mode disabled + +```json +{ + "type": "function", + "name": "get_weather", + "description": "Retrieves current weather for the given location.", + "parameters": { + "type": "object", + "properties": { + "location": { + "type": "string", + "description": "City and country e.g. BogotΓ‘, Colombia" + }, + "units": { + "type": "string", + "enum": ["celsius", "fahrenheit"], + "description": "Units the temperature will be returned in." + } + }, + "required": ["location"], + } +} +``` + +All schemas generated in the [playground](/playground) have strict mode enabled. + +While we recommend you enable strict mode, it has a few limitations: + +1. Some features of JSON schema are not supported. (See [supported schemas](/docs/guides/structured-outputs?context=with_parse#supported-schemas).) + +Specifically for fine tuned models: + +1. Schemas undergo additional processing on the first request (and are then cached). If your schemas vary from request to request, this may result in higher latencies. +2.

But rather than providing the model explicit instructions on what input your tool requires, the model can +pass an arbitrary string back to your tool as input. This is useful to avoid unnecessarily wrapping a response in JSON, or to apply a custom grammar to the response (more on this +below). + +The following code sample shows creating a custom tool that expects to receive a string of text containing Python code as a response. + +Custom tool calling example + +```python +from openai import OpenAI + +client = OpenAI() + +response = client.responses.create( + model="gpt-5", + input="Use the code_exec tool to print hello world to the console.", + tools=[ + { + "type": "custom", + "name": "code_exec", + "description": "Executes arbitrary Python code.", + } + ] +) +print(response.output) +``` + +```javascript +import OpenAI from "openai"; +const client = new OpenAI(); + +const response = await client.responses.create({ + model: "gpt-5", + input: "Use the code_exec tool to print hello world to the console.", + tools: [ + { + type: "custom", + name: "code_exec", + description: "Executes arbitrary Python code.", + }, + ], +}); + +console.log(response.output); +``` + +Just as before, the `output` array will contain a tool call generated by the model. Except this time, the tool call input is given as plain text. + +```json +[ + { + "id": "rs_6890e972fa7c819ca8bc561526b989170694874912ae0ea6", + "type": "reasoning", + "content": [], + "summary": [] + }, + { + "id": "ctc_6890e975e86c819c9338825b3e1994810694874912ae0ea6", + "type": "custom_tool_call", + "status": "completed", + "call_id": "call_aGiFQkRWSWAIsMQ19fKqxUgb", + "input": "print(\"hello world\")", + "name": "code_exec" + } +] +``` + +Context-free grammars +--------------------- + +A [context-free grammar](https://en.wikipedia.org/wiki/Context-free_grammar) (CFG) is a set of rules that define how to produce valid text in a given format. For custom tools, you can +provide a CFG that will constrain the model's text input for a custom tool. + +You can provide a custom CFG using the `grammar` parameter when configuring a custom tool. Currently, we support two CFG syntaxes when defining grammars: `lark` and `regex`. + +Lark CFG +-------- + +Lark context free grammar example + +```python +from openai import OpenAI + +client = OpenAI() + +grammar = """ +start: expr +expr: term (SP ADD SP term)* -> add +| term +term: factor (SP MUL SP factor)* -> mul +| factor +factor: INT +SP: " " +ADD: "+" +MUL: "*" +%import common.INT +""" + +response = client.responses.create( + model="gpt-5", + input="Use the math_exp tool to add four plus four.", + tools=[ + { + "type": "custom", + "name": "math_exp", + "description": "Creates valid mathematical expressions", + "format": { + "type": "grammar", + "syntax": "lark", + "definition": grammar, + }, + } + ] +) +print(response.output) +``` + +```javascript +import OpenAI from "openai"; +const client = new OpenAI(); + +const grammar = ` +start: expr +expr: term (SP ADD SP term)* -> add +| term +term: factor (SP MUL SP factor)* -> mul +| factor +factor: INT +SP: " " +ADD: "+" +MUL: "*" +%import common.INT +`; + +const response = await client.responses.create({ + model: "gpt-5", + input: "Use the math_exp tool to add four plus four.", + tools: [ + { + type: "custom", + name: "math_exp", + description: "Creates valid mathematical expressions", + format: { + type: "grammar", + syntax: "lark", + definition: grammar, + }, + }, + ], +}); + +console.log(response.output); +``` + +The output from the tool should then conform to the Lark CFG that you defined: + +```json +[ + { + "id": "rs_6890ed2b6374819dbbff5353e6664ef103f4db9848be4829", + "type": "reasoning", + "content": [], + "summary": [] + }, + { + "id": "ctc_6890ed2f32e8819daa62bef772b8c15503f4db9848be4829", + "type": "custom_tool_call", + "status": "completed", + "call_id": "call_pmlLjmvG33KJdyVdC4MVdk5N", + "input": "4 + 4", + "name": "math_exp" + } +] +``` + +Grammars are specified using a variation of [Lark](https://lark-parser.readthedocs.io/en/stable/index.html). Model sampling is constrained using +[LLGuidance](https://github.com/guidance-ai/llguidance/blob/main/docs/syntax.md). Some features of Lark are not supported: + +* Lookarounds in lexer regexes +* Lazy modifiers (`*?`, `+?`, `??`) in lexer regexes +* Priorities of terminals +* Templates +* Imports (other than built-in `%import` common) +* `%declare`s + +We recommend using the [Lark IDE](https://www.lark-parser.org/ide/) to experiment with custom grammars. + +### Keep grammars simple + +Try to make your grammar as simple as possible. The OpenAI API may return an error if the grammar is too complex, so you should ensure that your desired grammar is compatible before +using it in the API. + +Lark grammars can be tricky to perfect. While simple grammars perform most reliably, complex grammars often require iteration on the grammar definition itself, the prompt, and the tool +description to ensure that the model does not go out of distribution. + +### Correct versus incorrect patterns + +Correct (single, bounded terminal): + +```text +start: SENTENCE +SENTENCE: /[A-Za-z, ]*(the hero|a dragon|an old man|the princess)[A-Za-z, ]*(fought|saved|found|lost)[A-Za-z, ]*(a treasure|the kingdom|a secret|his way)[A-Za-z, ]*\./ +``` + +Do NOT do this (splitting across rules/terminals). This attempts to let rules partition free text between terminals. The lexer will greedily match the free-text pieces and you'll lose +control: + +```text +start: sentence +sentence: /[A-Za-z, ]+/ subject /[A-Za-z, ]+/ verb /[A-Za-z, ]+/ object /[A-Za-z, ]+/ +``` + +Lowercase rules don't influence how terminals are cut from the inputβ€”only terminal definitions do. When you need β€œfree text between anchors,” make it one giant regex terminal so the +lexer matches it exactly once with the structure you intend. + +### Terminals versus rules + +Lark uses terminals for lexer tokens (by convention, `UPPERCASE`) and rules for parser productions (by convention, `lowercase`). The most practical way to stay within the supported +subset and avoid surprises is to keep your grammar simple and explicit, and to use terminals and rules with a clear separation of concerns. + +The regex syntax used by terminals is the [Rust regex crate syntax](https://docs.rs/regex/latest/regex/#syntax), not Python's `re` [module](https://docs.python.org/3/library/re.html). + +### Key ideas and best practices + +**Lexer runs before the parser** + +Terminals are matched by the lexer (greedily / longest match wins) before any CFG rule logic is applied. If you try to "shape" a terminal by splitting it across several rules, the lexer +cannot be guided by those rulesβ€”only by terminal regexes. + +**Prefer one terminal when you're carving text out of freeform spans** + +If you need to recognize a pattern embedded in arbitrary text (e.g., natural language with β€œanything” between anchors), express that as a single terminal. Do not try to interleave +free‑text terminals with parser rules; the greedy lexer will not respect your intended boundaries and it is highly likely the model will go out of distribution. + +**Use rules to compose discrete tokens** + +Rules are ideal when you're combining clearly delimited terminals (numbers, keywords, punctuation) into larger structures. They're not the right tool for constraining "the stuff in +between" two terminals. + +**Keep terminals simple, bounded, and self-contained** + +Favor explicit character classes and bounded quantifiers (`{0,10}`, not unbounded `*` everywhere). If you need "any text up to a period", prefer something like `/[^.\n]{0,10}*\./` +rather than `/.+\./` to avoid runaway growth. + +**Use rules to combine tokens, not to steer regex internals** + +Good rule usage example: + +```text +start: expr +NUMBER: /[0-9]+/ +PLUS: "+" +MINUS: "-" +expr: term (("+"|"-") term)* +term: NUMBER +``` + +**Treat whitespace explicitly** + +Don't rely on open-ended `%ignore` directives. Using unbounded ignore directives may cause the grammar to be too complex and/or may cause the model to go out of distribution. Prefer +threading explicit terminals wherever whitespace is allowed. + +### Troubleshooting + +* If the API rejects the grammar because it is too complex, simplify the rules and terminals and remove unbounded `%ignore`s. +* If custom tools are called with unexpected tokens, confirm terminals aren’t overlapping; check greedy lexer. +* When the model drifts "out‑of‑distribution" (shows up as the model producing excessively long or repetitive outputs, it is syntactically valid but is semantically wrong): + * Tighten the grammar. + * Iterate on the prompt (add few-shot examples) and tool description (explain the grammar and instruct the model to reason and conform to it). + * Experiment with a higher reasoning effort (e.g, bump from medium to high). + +Regex CFG +--------- + +Regex context free grammar example + +```python +from openai import OpenAI + +client = OpenAI() + +grammar = +r"^(?PJanuary|February|March|April|May|June|July|August|September|October|November|December)\s+(?P\d{1,2})(?:st|nd|rd|th)?\s+(?P\d{4})\s+at\s+(?P0?[1-9]|1[0-2])(?PAM|PM)$" + +response = client.responses.create( + model="gpt-5", + input="Use the timestamp tool to save a timestamp for August 7th 2025 at 10AM.", + tools=[ + { + "type": "custom", + "name": "timestamp", + "description": "Saves a timestamp in date + time in 24-hr format.", + "format": { + "type": "grammar", + "syntax": "regex", + "definition": grammar, + }, + } + ] +) +print(response.output) +``` + +```javascript +import OpenAI from "openai"; +const client = new OpenAI(); + +const grammar = +"^(?PJanuary|February|March|April|May|June|July|August|September|October|November|December)\s+(?P\d{1,2})(?:st|nd|rd|th)?\s+(?P\d{4})\s+at\s+(?P0?[1-9]|1[0-2])(?PAM|PM)$"; + +const response = await client.responses.create({ + model: "gpt-5", + input: "Use the timestamp tool to save a timestamp for August 7th 2025 at 10AM.", + tools: [ + { + type: "custom", + name: "timestamp", + description: "Saves a timestamp in date + time in 24-hr format.", + format: { + type: "grammar", + syntax: "regex", + definition: grammar, + }, + }, + ], +}); + +console.log(response.output); +``` + +The output from the tool should then conform to the Regex CFG that you defined: + +```json +[ + { + "id": "rs_6894f7a3dd4c81a1823a723a00bfa8710d7962f622d1c260", + "type": "reasoning", + "content": [], + "summary": [] + }, + { + "id": "ctc_6894f7ad7fb881a1bffa1f377393b1a40d7962f622d1c260", + "type": "custom_tool_call", + "status": "completed", + "call_id": "call_8m4XCnYvEmFlzHgDHbaOCFlK", + "input": "August 7th 2025 at 10AM", + "name": "timestamp" + } +] +``` + +As with the Lark syntax, regexes use the [Rust regex crate syntax](https://docs.rs/regex/latest/regex/#syntax), not Python's `re` [module](https://docs.python.org/3/library/re.html). + +Some features of Regex are not supported: + +* Lookarounds +* Lazy modifiers (`*?`, `+?`, `??`) + +### Key ideas and best practices + +**Pattern must be on one line** + +If you need to match a newline in the input, use the escaped sequence `\n`.
