333-336: Use explicit Optional type annotations for consistency.The new parameters should use explicit
Optional[T]type annotations to match Python's type system recommendations and maintain consistency with the existing codebase.- start_backend: bool = False, - backend_host: str = "localhost", - backend_port: int = 8000, + start_backend: bool = False, + backend_host: str = "localhost", + backend_port: int = 8000,
412-414: Use logging.exception for better error diagnostics.When catching exceptions, use
logger.exception()instead oflogger.error()to include the full stack trace in the logs.- except Exception as e: - logger.error(f"Failed to start backend server: {str(e)}") + except Exception as e: + logger.exception("Failed to start backend server")
504-506: Document the custom attribute pattern.Using a custom attribute
_cognee_backend_processon the Popen object is unconventional. Consider documenting this pattern or using a more standard approach.Consider using a namedtuple or a custom class to encapsulate both processes:
from typing import NamedTuple class UIServerProcesses(NamedTuple): frontend: subprocess.Popen backend: Optional[subprocess.Popen] = NoneWould you like me to refactor this to use a more explicit data structure?
cognee/modules/data/methods/get_deletion_counts.py (1)
23-24: Consider more descriptive return for missing datasets.When a dataset is not found, consider including the dataset name in the response or throwing an exception to make debugging easier.
- if dataset is None: - return {"datasets": 0, "data_entries": 0} + if dataset is None: + return {"datasets": 0, "data_entries": 0, "message": f"Dataset '{dataset_name}' not found"}cognee/cli/commands/delete_command.py (1)
103-105: Avoid asserting success while delete is unreliable; soften message or verify post-delete.
To prevent false positives, either soften the message or re-check counts to confirm.Option A (softer message):
- fmt.success(f"Successfully deleted {operation}") + fmt.success(f"Requested deletion of {operation}")Option B (verify outcome; may be async-heavy):
- Re-run get_deletion_counts for the same scope and log a post-delete summary; only print “Successfully deleted …” if counts dropped to zero (or decreased).

543-559: Good error handling for backend cleanup.The implementation properly handles backend process cleanup with graceful termination followed by forced kill if necessary. The error handling is appropriate and logs are informative.
383-398: Incorrect — subprocess uses argv list (no shell); validate host/port insteadsubprocess.Popen is invoked with a list (shell=False) in cognee/api/v1/ui/ui.py:383–392, so shell-based command injection via backend_host/backend_port is not applicable; still add validation to ensure backend_host is a valid hostname/IP and backend_port is an int in 1–65535 to avoid malformed values or accidental exposure.
Suggested quick patch (add before line 383):
import re import ipaddress # Validate backend_host if not isinstance(backend_host, str) or not backend_host: raise ValueError(f"Invalid backend_host: {backend_host!r}") try: ipaddress.ip_address(backend_host) except ValueError: if not re.fullmatch( r"[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?(?:\.[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?)*", backend_host, ): raise ValueError(f"Invalid backend_host: {backend_host!r}") # Validate backend_port try: backend_port = int(backend_port) except (TypeError, ValueError): raise ValueError(f"Invalid backend_port: {backend_port!r}") if not (1 <= backend_port <= 65535): raise ValueError(f"Invalid backend_port: {backend_port}. Must be 1-65535.")Likely an incorrect or invalid review comment.

209-211: LGTM! Backend auto-start integration is clean.The integration of the backend auto-start feature is well-implemented with the

216-216: Good user communication about backend availability.The addition of the backend URL information helps users understand what services are available.

27-32: Efficient database query implementation.Good use of SQLAlchemy's func.count() for efficient counting without loading all records into memory.
36-50: Comprehensive counting for all_data mode.The implementation correctly counts all datasets, data entries, and users when deleting all data. The queries are efficient and the return structure is consistent.

9-9: LGTM: import adds the required dependency for preview counts.
Clean, explicit import; avoids circulars by using late import for cognee below.
72-75: Confirmation defaults to No — good.
The prompt uses default=False via fmt.confirm; meets safety requirement.
93-95: Track the underlying delete bug and gate user-facing success accordingly.
Good to document the known issue; ensure there’s a linked issue reference in code or commit for traceability. Until fixed, prefer non-committal success messaging (see next comment).

🛠️ Refactor suggestion
Fix unsafe mismatch between preview scope and actual deletion; enforce exclusivity and align param mapping.
If a user passes multiple target flags (e.g., --all with --dataset-name), preview uses dataset scope (get_deletion_counts prioritizes dataset_name) but deletion currently takes the --all branch. That can delete more than previewed.
Apply these diffs to align the operation label and deletion params with a single, consistent precedence (dataset > user > all):
- if args.all:
- operation = "all data"
- elif args.dataset_name:
- operation = f"dataset '{args.dataset_name}'"
- elif args.user_id:
- operation = f"data for user '{args.user_id}'"
- else:
- operation = "data"
+ if args.dataset_name:
+ operation = f"dataset '{args.dataset_name}'"
+ elif args.user_id:
+ operation = f"data for user '{args.user_id}'"
+ elif args.all:
+ operation = "all data"
+ else:
+ operation = "data"- if args.all:
- await cognee.delete(dataset_name=None, user_id=args.user_id)
- else:
- await cognee.delete(dataset_name=args.dataset_name, user_id=args.user_id)
+ # Execute deletion with the same scope used for preview
+ if args.dataset_name:
+ await cognee.delete(dataset_name=args.dataset_name, user_id=None)
+ elif args.user_id:
+ await cognee.delete(dataset_name=None, user_id=args.user_id)
+ elif args.all:
+ await cognee.delete(dataset_name=None, user_id=None)
+ else:
+ raise CliCommandInnerException("No deletion target provided (unexpected).")Additionally, make the targets mutually exclusive at the parser level (outside this hunk) to prevent conflicting flags:
# in configure_parser(...)
group = parser.add_mutually_exclusive_group(required=True)
group.add_argument("--dataset-name", "-d", help="Specific dataset to delete")
group.add_argument("--user-id", "-u", help="User ID to delete data for")
group.add_argument("--all", action="store_true", help="Delete all data (requires confirmation)")
parser.add_argument("--force", "-f", action="store_true", help="Skip confirmation prompts")This also lets you drop the manual validation branch.

Fall back to direct delete if preview metrics retrieval fails.
Acceptance requires continuing with deletion when metrics can’t be fetched. Currently, any failure aborts the command.
Apply this diff to catch preview failures and proceed without preview:

- dataset_name=args.dataset_name,
- user_id=args.user_id,
- all_data=args.all,
- )

+ dataset_name=args.dataset_name,
+ user_id=args.user_id,

+ )
+ except Exception as ex:
+ fmt.warning(f"Could not retrieve preview metrics; proceeding without preview. Reason: {ex}")
+ preview_data = None

Implement user_id deletion counts.
The user_id functionality is marked as TODO but returns placeholder data. This could mislead users about what will actually be deleted.
The placeholder return value {"datasets": 0, "data_entries": 0, "users": 1} is misleading. Either implement the actual counting logic or return an error/warning to the user.
Would you like me to help implement the user_id counting logic? This would involve:
- Counting datasets owned by the user
- Counting data entries associated with those datasets
- Returning accurate counts
Description
This pull request implements the "Delete Command Preview" enhancement. The cognee delete command now includes a preview step that summarizes what will be deleted before asking for user confirmation. This improves usability and safety by helping users understand the scope of the deletion.
During development, it was discovered that the underlying cognee.delete() function for datasets appears to be failing silently. This new preview feature correctly shows the user what should be deleted, which helps to expose this separate, pre-existing bug.
Type of Change
[ ] Bug fix (non-breaking change that fixes an issue)
[x] New feature (non-breaking change that adds functionality)
[ ] Breaking change (fix or feature that would cause existing functionality to change)
[ ] Documentation update
[ ] Code refactoring
[ ] Performance improvement
[ ] Other (please specify):
Changes Made
Created a new function get_deletion_counts to efficiently query the relational database for the number of affected datasets, data entries, and users.
Modified delete_command.py to call this new function and display a formatted preview to the user.
Integrated the --force flag to allow skipping the new preview and confirmation step.
Added a "No data found to delete" message when the target of the deletion is empty, preventing unnecessary prompts.
Testing
Tested the delete --dataset-name case by adding a new dataset with cognee add and verifying that the preview correctly showed "1 datasets" and "1 data entries".
Tested delete --all and confirmed it displayed the total counts of all data in the system.
Wrote and used a helper script to get the default user ID and tested the delete --user-id case.
Confirmed that answering "n" to the confirmation prompt correctly cancels the operation.
Confirmed that the --force flag skips the preview and proceeds directly to the deletion attempt.

Additional Notes
This PR focuses solely on adding the preview functionality as requested. It does not fix the underlying issue where cognee.delete(dataset_name=...) fails silently. However, this feature makes that bug clearly visible to the user, as the preview will show the correct counts, but the data will remain after the operation.
