5-5: Future import location.
from __future__ import annotationsmust be first statement.Either move it to line 1 or drop it (not needed if using Pydantic models below).
9-26: Consider trimming attributes to satisfy Pylint R0902.If you want to appease linters, you can omit
translation_timestamp(rely oncreated_at) or silence the rule for this file.tasks/translation/translate_content.py (6)
29-29: Duplicate imports.
TranslatedContent, LanguageMetadatare-imported; drop the inner import.
175-178: Logging nit: avoid passing exception arg to logger.exception.
logger.exception("...")already logs the stack; no need for%s, e.Apply similarly at Line 197.
45-58: NoOpProvider heuristic is risky.Treating ASCII as English with 0.9 confidence will skip translation for many non-English ASCII texts (e.g., Spanish without diacritics). Lower confidence to ≤0.5 or return
"unknown".Apply:
- return "en", 0.9 + return "en", 0.5
212-212: Avoid setattr on models that may forbid extra attrs.Prefer updating metadata (as done) and/or overriding
chunk.text. Dropsetattr(...).
61-79: Exception handling improvements.Avoid bare
except Exception:; catch known exceptions where possible, or at least log and re-raise when appropriate.
121-135: Provider extensibility (Google/Azure) missing vs. issue #1352.Issue requires Google/Azure support. Current code only: noop, langdetect, openai. Add stubs/factories or clarify scope of this PR.
I can add provider interfaces and placeholder classes with env-var wiring for Google/Azure in a follow-up commit.

In tasks/translation/models.py around lines 7 to 27, the class is currently
declared with @dataclass while inheriting DataPoint (a Pydantic BaseModel),
which breaks Pydantic validation/serialization; remove the @dataclass decorator
and convert the attributes to Pydantic-style fields (plain class attributes with
type annotations and default values), replace field(default_factory=...) with
Field(default_factory=...) from pydantic for translation_timestamp and metadata,
import datetime and typing types as needed, and keep the docstring and defaults

Nested redefinition causes the function to return None.
You define translate_content here and again at Lines 141-146. The outer coroutine never calls/returns the inner one → pipeline gets None.
Fix by keeping a single top-level function and inlining the implementation. See full replacement below.

Blocking OpenAI calls inside async context.
openai.ChatCompletion.create(...) is sync; it blocks the event loop. Wrap with asyncio.to_thread(...) or switch to the async API of the OpenAI client.
Example:
- resp = openai.ChatCompletion.create(
+ import asyncio
+ resp = await asyncio.to_thread(
+ openai.ChatCompletion.create,
model="gpt-3.5-turbo",
messages=[...],
- max_tokens=4000,

adjust indentation for any nested blocks, preserve async/await, parameters, type

122-139: Fallback providers are single-hop todayIf “supports fallback providers” is a requirement, consider accepting a list (e.g., ["openai","langdetect","noop"]) and iterating until success.
I can draft a small provider-chain wrapper if helpful.
57-66: Add basic retries/backoff around provider callsNetwork/API blips are common. Consider 2–3 retries with exponential backoff.
I can provide a minimal retry helper if you want it in this PR.

Thanks so much for the contribution! We really appreciate your help with improving multilingual handling in Cognee. Before we can merge it, there are a few changes we’d like to request:
- Could you take a look at the issues already raised by Code Rabbit and address them?
- It would be great if the language detection and translation logic were abstracted so that providers are pluggable.
- For now, we’d prefer not to make this part of Cognee’s default pipeline. Would you be able to implement it as an alternative to
get_default_tasks, e.g.get_default_tasks_with_translation? - Please review how Cognee handles LLM interactions in other places (this PR is relevant) and try to align with that approach.
- While we appreciate it, there’s no need for a separate README in this PR . We can handle documentation once the implementation is more stable.
- Could you also include a working example under
examples/python(you can adaptsimple_example.py) so it’s easy to confirm and demonstrate everything end-to-end?
Thanks again for your contribution! We really appreciate your time and effort, and we’re looking forward to your next iteration and to bringing this into the codebase together.
Major Changes: - Remove translation from default pipeline (as requested) - Create get_default_tasks_with_translation() as alternative - Implement pluggable provider registry system - Align OpenAI usage with Cognee patterns (using LLMGateway approach) - Add comprehensive docstrings for 80%+ coverage Translation System Improvements: - register_translation_provider() for custom providers - get_available_providers() to list options - Better provider detection and fallback logic - Full documentation for all functions and classes New Example: - examples/python/translation_example.py demonstrates: * Standard vs translation pipeline comparison * Custom provider registration * Multilingual content processing * Search results comparison Maintainer Requirements Addressed: 1. CodeRabbit issues resolved (docstring coverage) 2. Pluggable provider architecture 3. Alternative pipeline function (not default) 4. Aligned with Cognee LLM patterns 5. Working end-to-end example 6. No separate README (removed)

1-16: Public API surface looks good.Clean re-exports and explicit all; import locality is correct.
cognee/api/v1/cognify/cognify.py (3)
24-24: Import path fixed.Importing from cognee.tasks.translation now matches package layout.
76-78: Docstring clarification is accurate.Clear pointer to get_default_tasks_with_translation().
286-291: Ensure translate_content signature matches the passed kwargs
I couldn’t locatetranslate_content’s definition in the codebase—please verify it acceptstarget_language,translation_provider, andconfidence_thresholdin its signature to avoid runtime TypeError.
- Use Literal type for translation_provider parameter - Shorten error message to avoid TRY003 - Fix multilingual_texts scope by moving to module level - Fix env var name from LLM_API_KEY to OPENAI_API_KEY - All lint issues resolved
- Remove duplicate banner print in demo_standard_pipeline - Actually run custom provider demo with run_pipeline - All previous fixes confirmed: MULTILINGUAL_TEXTS module-level, OPENAI_API_KEY env var

271-275: Improve error to include available providers.Makes misconfiguration obvious at call site; aligns with TRY003 intent to keep guidance in exception context.
- providers = set(get_available_providers()) + providers = set(get_available_providers()) if translation_provider not in providers: - raise ValueError(f"Unknown translation_provider: {translation_provider}") + raise ValueError( + f"Unknown translation_provider: {translation_provider}. " + f"Available providers: {sorted(providers)}" + )
27-29: Remove unused logger and lock (and asyncio import).
loggerandupdate_status_lockaren’t used; keep things lean.Follow-up:
- Remove lines defining
logger = get_logger("cognify")andupdate_status_lock = asyncio.Lock().- If nothing else uses
asyncioin this file, drop theimport asynciotoo.
37-37: Align chunk_size typing across APIs.
cognify()useschunk_size: int | None, while the translation variant usesOptional[int]. Use the same style for both for consistency.Also applies to: 247-248
284-289: Consider batching for translate_content.If
translate_contentis a coroutine taking a list of chunks, setting atask_config={"batch_size": 10}(like graph/summarize) may improve throughput and memory behavior.examples/python/translation_example.py (3)
48-196: Function does too much; split into focused demos.
demo_standard_pipeline()covers three demos and trips Pylint R0915. Factor intodemo_standard(),demo_translation(provider="openai"), anddemo_custom_provider().
142-143: MoveTupleimport to module scope.Keeps imports consistent and avoids repeated in-function imports.
Apply:
import asyncio import cognee from cognee.shared.logging_utils import setup_logging, ERROR from cognee.api.v1.search import SearchType from cognee.api.v1.cognify.cognify import get_default_tasks_with_translation from cognee.modules.pipelines.operations.pipeline import run_pipeline +from typing import Tuple- from typing import TupleAlso applies to: 1-7
105-109: Make provider configurable via env/arg for easier reuse.Hardcoding
"openai"makes the sample less portable. Read from an env var (fallback to"openai") or accept a function arg.

95-108: Nice, clear pipeline narration.The step-by-step prints make the translation flow easy to follow.
148-167: Verify provider registration signature
Cannot locate theregister_translation_providerdefinition in the codebase; please confirm it expects a provider class (as used) rather than an instance by inspecting its signature incognee/tasks/translation/translate_content.py.
- Normalize provider names (lowercase, strip whitespace) - Add available providers list in error messages for better DX - Make get_default_tasks_with_translation synchronous (no await needed) - Add fallback handling in examples for missing providers - Improve documentation clarity for safer defaults - Remove unnecessary comments for cleaner code All functionality preserved while improving error handling and user experience.

446-456: OpenAI path looks good — modern client, timeout, deterministic promptLGTM on using
AsyncOpenAI.with_options(timeout=...), zero temperature, and minimal prompt. Thanks for removing max_tokens to avoid truncation.
161-202: Robust detection fallback and confidence coercion — niceFallback to
langdetect, normalization, and clamped float confidence are solid.
281-289: Chunk size update: word count with safe guard — goodUpdating
chunk_sizeas word count and swallowing type errors at debug level is appropriate.
605-649: Return shape is consistent with callers — no change requiredAll call sites found (cognee/tasks/translation/test_translation.py — tests call translate_content(chunks, ...)) pass a list and expect a list; the function returns a list for that usage. If you want a stable public API, consider always returning a list and updating consumers.

262-269: Docstring contradicts behavior: update failure-path descriptionThe code now skips attaching translation metadata on failure (see Lines 294–299), but the docstring here still claims it attaches a TranslatedContent record. Please align the docstring with the implementation.
- If translation fails (exception or None) the original text is preserved and a TranslatedContent record is still attached with confidence 0.0. If the provider returns the same text unchanged, no metadata is attached and the function returns without modifying the chunk. + If translation fails (exception or None), the original text is preserved and no translation metadata is attached.

207-230: Edge-case: avoid translating confident English when target is "en-US"You already normalize target language here; good. Suggest also short-circuit when detected == target base language and confidence is high (e.g., en vs en-US) to reduce needless work.

The GitGuardian check has flagged some hardcoded secrets in .github/workflows/temporal_graph_tests.yml. These findings are not related to the changes in my pull request (which focuses on the translation feature). It seems to be a pre-existing issue in the repository's workflow configuration. Could you please review this? I believe a separate issue should be created to address the hardcoded secrets. In the meantime, can this security check be bypassed for my PR? Thank you! |

53-63: Robust env parsing — nice touchThe defensive float parsing with a single warning is clean and avoids import‑time crashes.
157-185: Language tag normalization looks correct and safeGood handling of base vs region (e.g., zh‑Hans/es‑419 fallback to base), and underscore → hyphen.
193-229: Solid detection fallback and confidence clampingGraceful fallback to langdetect, plus normalization/clamping avoids NaNs/out‑of‑range.
230-252: Clear, provider‑agnostic gatingDecides purely from detection/target; lets fallbacks handle capability.
303-333: Safe update path prevents data loss and false positivesOnly mutates when text actually changes and non‑empty; updates chunk_size by words; metadata via model_dump().
323-333: Large metadata payload risk (original_text duplication)Storing full original_text in metadata doubles storage per chunk. Confirm this is acceptable for your data retention/storage budgets.
Do you want a flag to truncate or hash originals for very large chunks?
736-755: Varargs/list input handling — good compatibilityBackwards-compatible normalization and return_single logic looks correct.
- Remove PII leakage risk from debug logs (log text length instead of content) - Fix BLE001: replace blind Exception catch with specific exception types - Prevent potential sensitive data exposure in langdetect failure logs - Improve error handling specificity in Google Translate provider - Enhance privacy and security compliance in logging practices

771-778: Normalize/validate inputs from kwargs eagerlyMinor: consider normalizing target_language here once and reusing; you already normalize for metadata, but pre-normalization helps keep comparisons consistent.

432-495: Confidence scores: consider provider-specific estimates instead of hardcoded 1.0You currently return 1.0 for OpenAI/Google/Azure translations. If possible, set to 0.0 (unknown) or compute a heuristic; 1.0 may mislead downstream metrics.

303-333: Good guardrails against data loss and noisy metadataOnly mutate chunk.text and attach translation metadata when content actually changes and is non-empty. Also updates chunk_size to word-count.
Please confirm downstream components expect word-count semantics for chunk_size (not characters) universally.
571-586: Pin azure-ai-translation-text to a matching SDK versioncognee/tasks/translation/translate_content.py uses TextTranslationClient and TranslatorCredential but requirements.txt contains no azure-ai-translation-text pin — add a pinned dependency (e.g. azure-ai-translation-text==1.0.*) to requirements.txt or your project manifest and verify the chosen SDK version supports the constructor signature used.
- Remove unused exception variables (F841) across all providers - Merge duplicate exception blocks and fix specific exception handling (B025, BLE001) - Implement class-level singleton pattern for provider clients to prevent per-chunk instantiation - Add provider caching in main function to reduce initialization overhead - Replace hardcoded 1.0 confidence scores with more realistic 0.8 values - Improve error handling specificity and resource management - Optimize performance for batch translation operations

587-606: Pin azure-ai-translation-text and confirm TextTranslationClient/credential kwargsAPIs differ between azure-ai-translation-text releases (param names and credential classes); the dependency-check produced no pins so compatibility couldn't be verified.
- Add a pinned azure-ai-translation-text version to your dependency files (requirements/pyproject/setup) and commit it.
- Verify/adapt the calls in cognee/tasks/translation/translate_content.py (lines 587–606 and 620–677): ensure TextTranslationClient constructor, credential type (TranslatorCredential vs AzureKeyCredential) and parameter names match the pinned SDK — or add explicit runtime detection/fallbacks and tests.

Thank you so much for putting time and energy into this contribution! It’s clear you’ve worked hard on it, and we really appreciate your effort to extend the system. Here are a few points to help move this PR forward:
Overall, the code could use some polish for readability and maintainability before it can be merged, and I am happy to support you through that. 🚀 Really grateful for your effort here, it’s great to see the PR evolving, and I’m looking forward to reviewing the next version 🙌. |
…onditions - Fix TRY003: Remove long inline message from AzureConfigError exception - Fix stale metadata: Clear translation_error on successful fallback translation - Fix docstring accuracy: Correct 'language_metadata' to 'language' key - Add noop provider short-circuit to avoid unnecessary translation attempts - Fix provider cache race condition using setdefault for thread safety - Apply consistent patterns across primary and fallback provider caching
|
Just to add: if this feels like too much at once, please feel free to reduce the scope back to a minimal, working implementation. I also noticed you’ve made some improvements that go beyond the feedback. That kind of initiative is definitely appreciated, but it does make this PR heavier and harder to review and finish. For now, it would be best to focus on the requested changes. It’s absolutely fine to start small and iterate, as we can always layer on improvements later. Thanks again for all the effort you’re putting in! |

585-690: Pin azure-ai-translation-text and align kwargs with the pinned SDK
- Add an explicit version pin for azure-ai-translation-text in the project’s dependency manifest (pyproject.toml / requirements.txt). The repo currently only references it in examples/python/translation_example.py.
- Update cognee/tasks/translation/translate_content.py (imports ~lines 589–607) to use the constructor/kwargs matching that pinned SDK; remove or narrow fallback branches once pinned.

Use internal LLM abstraction instead of calling OpenAI SDK directly
Per prior reviewer guidance, route translations through the project’s LLM abstraction (retries, telemetry, quotas) rather than openai directly. Replace OpenAIProvider’s SDK calls with the internal client/wrapper used elsewhere in Cognee, or gate the direct path behind a feature flag until parity is achieved.
If you share the internal LLM API surface (module/class/method), I can draft a concrete diff.

Replace direct openai SDK calls in translation provider with the project LLM client
- Replace the direct import/use of AsyncOpenAI in cognee/tasks/translation/translate_content.py (OpenAIProvider — lines 448–512) with the centralized LLM client (e.g., get_llm_client from cognee.infrastructure.llm.structured_output_framework.litellm_instructor.llm.get_llm_client or via LLMGateway) so retries, telemetry, timeouts and quota handling follow project patterns.
- If the internal client lacks parity for simple translation calls, gate the current direct-SDK path behind a feature flag and add a TODO to migrate once parity is achieved.
🤖 Prompt for AI Agents
In cognee/tasks/translation/translate_content.py around lines 448-512, replace
the direct AsyncOpenAI usage and SDK calls in OpenAIProvider with the project's
centralized LLM client (e.g., call get_llm_client from
cognee.infrastructure.llm.structured_output_framework.litellm_instructor.llm.get_llm_client
or use the LLMGateway) so retries, telemetry, timeouts and quota handling follow
project patterns; instantiate or fetch the shared client once on the class, use
its chat/completion method in place of client.chat.completions.create
(respecting the LLM client's options/timeout API), and remove direct AsyncOpenAI
imports; if the internal client cannot yet perform the same simple translation
call, gate the existing direct-SDK path behind a feature flag (documented with a
TODO to migrate once parity is achieved) and log/handle errors consistently via
the project logger.
