Summary

  • Fixes context_delegate.input.insights array property missing required items declaration, which caused OpenAI-compatible providers to reject the tool schema with invalid_function_parameters
  • Adds regression test that scans all tool schemas to ensure every type: 'array' property has items declared
  • Bumps version to 0.12.2

Test plan

  • New test issue33-array-items-schema.test.ts fails before fix, passes after
  • Full test suite passes (1188 tests)
  • ESLint, Prettier, TypeScript type-check all pass (pre-commit hooks)

Closes #33

fix(schema): add missing items to context_delegate.insights array (#33)
a89eb45 
OpenAI-compatible providers reject tool schemas where array properties
lack an items declaration. Added items: { type: 'string' } and a
regression test that validates all array properties across all tools.

Closes #33

Code Review

This PR effectively addresses the JSON Schema compliance issue that was causing OpenAI-compatible providers to reject the tool schema. Here's my detailed analysis:

✅ Core Fix Quality

The fix is correct and minimal:

  • Added items: { type: 'string' } to the insights property in context_delegate tool schema (src/index.ts:1247)
  • This satisfies the JSON Schema specification requirement that type: 'array' properties must declare their items schema
  • The fix is precisely targeted - only changes what's needed to resolve the compatibility issue

✅ Excellent Test Coverage

The regression test (src/tests/integration/issue33-array-items-schema.test.ts) is exceptionally well-designed:

  1. Generic detection: findArrayPropertiesMissingItems() scans all tool schemas for missing items declarations
  2. Specific validation: Dedicated test for the context_delegate.insights property
  3. Robust parsing: Uses sophisticated depth tracking to properly parse nested JSON schema objects
  4. Future-proof: Will catch any new array properties added without items declarations

Code Quality Notes:

  • The test parsing logic is sophisticated and handles edge cases well
  • Good use of regex patterns and depth tracking for schema analysis
  • Clear, descriptive test cases with helpful comments

✅ Version Management

  • Version bump to 0.12.2 is appropriate for this bugfix
  • CHANGELOG.md entry is comprehensive and well-structured
  • Follows semantic versioning correctly

✅ No Security or Performance Issues

  • The change is purely additive to the schema
  • No runtime behavior changes
  • No new dependencies or attack surfaces introduced

🟡 Minor Suggestions for Improvement

  1. Test file location: Consider moving the test to src/__tests__/unit/ since it's testing schema structure rather than integration behavior

  2. Test efficiency: The findArrayPropertiesMissingItems function could be optimized slightly by early-exiting when depth goes too negative, but this is minor given it only runs in tests

✅ Overall Assessment

This is a high-quality fix that:

  • Solves the immediate compatibility problem with OpenAI providers
  • Includes comprehensive regression testing
  • Follows proper versioning and documentation practices
  • Makes no unnecessary changes

The approach is exactly right: minimal fix + robust testing to prevent regression.

Recommendation: ✅ APPROVE

This PR is ready to merge. The fix is correct, well-tested, and follows best practices.

fix(review): correct insights type to object, fix test docstring and …
5d51bcd 
…comment handling

Review findings:
- insights items type changed from string to object (handler accesses
  insight.patterns, insight.relationships, etc.)
- Fixed misleading docstring that said dist/index.js when test reads src/index.ts
- Added block comment stripping to match tool-profiles-integration.test.ts convention

fix(review): correct CHANGELOG, fix line numbers, clean up scanner
e7e351c 
Round 2 review fixes:
- CHANGELOG: string → object to match actual code
- CHANGELOG: add missing [0.12.2] link reference
- Scanner: track block-comment state inline instead of stripping
  (preserves original line numbers for accurate debugging)
- Scanner: remove redundant regex branch

fix(schema): harden object schemas for strict validators
4dd0a65 
- Add properties to context_delegate.input.insights items (patterns,
  relationships, trends, themes) instead of bare { type: 'object' }
- Add properties: {} to context_link.metadata bare object schema
- Fix test scanner to handle single-line array declarations
- Update CHANGELOG to reflect all schema hardening

test(e2e): add comprehensive server E2E tests
de22fee 
Spawns the actual MCP server over stdio and validates:

Schema validation (via tools/list):
- Every tool has name, description, inputSchema
- Every array property has items declared (#33 regression)
- Every property type is a valid JSON Schema type
- Every required field references an existing property
- Enum values match their declared type
- No duplicate tool names

Smoke tests (via tools/call):
- Save and retrieve a context item
- Search for saved items
- Get server status
- Unknown tool returns error
- Missing required args handled gracefully
- Default profile exposes all 38 tools
