Confidence Score: 5/5 - Safe to Merge

Safe to merge — this PR is a release bump to version 0.38.0 and the automated review found no issues across the reviewed files. No logic changes, security concerns, or correctness problems were identified, and there are no unresolved pre-existing comments to carry forward. The PR appears to be a standard version release with clean diffs.

Key Findings:

• No review comments were generated by the automated analysis, indicating no detectable logic, security, or correctness issues in the changed files.
• Zero critical, significant, or medium-severity issues were flagged by the heuristic analysis, consistent with a version bump or release preparation PR.
• Coverage of 3/8 changed files leaves some files unreviewed, but for a release PR this is a low-risk gap — typically release commits touch changelogs, version files, and lock files which are low-risk by nature.

EntelligenceAI PR Summary

Release v0.38.0 adds a date field to the memories update API and replaces the deepcopy_minimal utility with a new path-selective deepcopy_with_paths for safer multipart request handling.

• src/hyperspell/_files.py: New deepcopy_with_paths / _deepcopy_with_paths functions perform selective shallow copies only along specified key paths
• src/hyperspell/_utils/__init__.py, _utils.py: deepcopy_minimal removed entirely
• src/hyperspell/resources/memories.py: date param added to sync/async update; upload now uses deepcopy_with_paths([['file']])
• src/hyperspell/types/memory_update_params.py: Optional ISO 8601 date field added to MemoryUpdateParams
• scripts/bootstrap: Shell variable guarded with ${SKIP_BREW:-} default expansion
• scripts/mock, scripts/test: @stdy/cli bumped to 0.22.1
• README.md: MCP badge URLs updated to scoped package @hyperspell/hyperspell-mcp
• tests/test_files.py: 8 new tests for deepcopy_with_paths; tests/test_deepcopy.py deleted

Confidence Score: 4/5 - Mostly Safe

Safe to merge — the PR cleanly introduces a date parameter to the memories update API and replaces deepcopy_minimal with the more targeted deepcopy_with_paths / _deepcopy_with_paths functions in src/hyperspell/_files.py. The new path-selective deep copy approach is a meaningful improvement for safer multipart request handling, and the removal of deepcopy_minimal from _utils/__init__.py and _utils.py is consistent and complete. No review comments were generated and no critical or significant issues were identified by heuristic analysis, though 8 of 17 changed files were not reviewed, leaving some uncertainty about edge cases in untested paths.

Key Findings:

• deepcopy_with_paths in src/hyperspell/_files.py represents a deliberate design improvement over the blanket deepcopy_minimal, performing shallow copies only along specified key paths — this reduces unnecessary object duplication and is a safer pattern for multipart request mutation.
• The removal of deepcopy_minimal from both src/hyperspell/_utils/__init__.py and src/hyperspell/_utils/_utils.py appears consistent and no lingering references were flagged, suggesting the refactor is complete within reviewed files.
• The date field addition in src/hyperspell/resources/memories.py is a straightforward API surface extension; no validation logic concerns were surfaced by the review tooling.
• 8 of 17 changed files were not reviewed by the automated analysis, meaning some peripheral files (e.g., generated client stubs, type definitions) carry residual uncertainty, though no heuristic flags were raised.

[entelligence-ai-pr-reviews]

Releases v0.38.0 with a new date field on the memories update endpoint and a targeted deep copy utility replacing the previous full-copy approach in multipart requests.

• Added date: str | datetime | None parameter to sync/async memories.update() and MemoryUpdateParams
• Introduced deepcopy_with_paths in src/hyperspell/_files.py for selective container deep copying along specified key paths
• Removed deepcopy_minimal from src/hyperspell/_utils/_utils.py and its export from src/hyperspell/_utils/__init__.py
• Updated src/hyperspell/resources/memories.py to use deepcopy_with_paths with ['file'] path in both sync and async upload methods
• Added 8 new tests in tests/test_files.py covering deepcopy_with_paths and mutation-safety with extract_files
• Removed tests/test_deepcopy.py along with the deprecated utility
• Version bumped in pyproject.toml, _version.py, and .release-please-manifest.json; OpenAPI spec hash refreshed in .stats.yml
