Luong NGUYEN b9a973bf32 docs: accuracy pass against Claude Code v2.1.220 (#155)
Internal accuracy pass against v2.1.220 — no missing upstream features, but broken example code, disagreeing counts, and metadata drift.

Functional fixes: pre-commit.sh now exits 2 so it actually blocks; dependency-check.sh reads file_path from stdin JSON instead of $1; database-mcp.json uses ${DATABASE_URL}; broken fences repaired; three command templates had invalid skill names.

Factual corrections: /fork and /subtask unswapped and /subtask added; /fewer-permission-prompts; permissions.defaultMode; dontAsk/auto unreversed; 31 hook events verified name-by-name; subagent depth 3; skill precedence enterprise > project > personal; /output-style removed not deprecated; permissionDecision gained defer.

Follow-up review fixed defects the pass left behind: zh/vi headers claiming 31 events above 25-name lists, a surviving hardcoded DB credential in the MCP README examples, an unbalanced fence swallowing a metadata footer, and non-canonical tool names. All four translated CATALOG summary tables were recounted so their arithmetic holds.

Full detail in CHANGELOG.md under v2.1.220-r2.

unit-test-expand Increase test coverage by targeting untested branches and edge cases

Expand Unit Tests

Expand existing unit tests adapted to project's testing framework:

  1. Analyze coverage: Run coverage report to identify untested branches, edge cases, and low-coverage areas
  2. Identify gaps: Review code for logical branches, error paths, boundary conditions, null/empty inputs
  3. Write tests using project's framework:
    • Jest/Vitest/Mocha (JavaScript/TypeScript)
    • pytest/unittest (Python)
    • Go testing/testify (Go)
    • Rust test framework (Rust)
  4. Target specific scenarios:
    • Error handling and exceptions
    • Boundary values (min/max, empty, null)
    • Edge cases and corner cases
    • State transitions and side effects
  5. Verify improvement: Run coverage again, confirm measurable increase

Present new test code blocks only. Follow existing test patterns and naming conventions.
