## [Informational] Pre-existing Issues (Not Blocking)

### Outdated Dependencies

The following dependencies are outdated but were **not modified in this branch**:

| Package | Current | Wanted | Latest | Type | Risk |
|---------|---------|--------|--------|------|------|
| @modelcontextprotocol/sdk | 1.19.1 | 1.23.0 | 1.23.0 | prod | LOW - minor version bump |
| @types/node | 24.3.0 | 24.10.1 | 24.10.1 | dev | LOW - type definitions |
| @vitest/coverage-v8 | 3.2.4 | 3.2.4 | 4.0.14 | dev | MEDIUM - major version |
| @vitest/ui | 3.2.4 | 3.2.4 | 4.0.14 | dev | MEDIUM - major version |
| better-sqlite3 | 12.4.1 | 12.5.0 | 12.5.0 | prod | LOW - patch version |
| simple-git | 3.28.0 | 3.30.0 | 3.30.0 | prod | LOW - minor version |
| tsx | 4.20.4 | 4.20.6 | 4.20.6 | dev | LOW - patch version |
| typescript | 5.9.2 | 5.9.3 | 5.9.3 | dev | LOW - patch version |
| vitest | 3.2.4 | 3.2.4 | 4.0.14 | dev | MEDIUM - major version |
| zod | 3.25.76 | 3.25.76 | 4.1.13 | prod | HIGH - major version |

### Security Vulnerabilities

**None detected.** `npm audit` reports 0 vulnerabilities across all severity levels.

### Version Pinning

All dependencies use caret (`^`) versioning, which is **acceptable** for most projects but should be noted:
- `@modelcontextprotocol/sdk`: ^1.19.1
- `better-sqlite3`: ^12.4.1
- `simple-git`: ^3.28.0
- `zod`: ^3.25.76

**Recommendation**: Consider using exact versions for production dependencies in lock-step CI/CD environments to ensure reproducible builds.

### Dependency Conflicts

**None detected.** No peer dependency warnings or conflicts found.

### Unused Dependencies

**None detected.** All declared dependencies are actively imported in the codebase:
- `@modelcontextprotocol/sdk`: Used in mcp-adapter.ts, index.ts
- `better-sqlite3`: Used in database.ts, task-repository.ts, output-repository.ts, dependency-repository.ts
- `simple-git`: Used in worktree-manager.ts
- `zod`: Used in configuration.ts, mcp-adapter.ts

### License Compliance

**No issues.** All dependencies use permissive licenses:
- MIT License: Majority of dependencies
- ISC License: chownr
- Apache-2.0: detect-libc

All licenses are compatible with MIT (the project's license).

## Summary

### Your Changes
- [BLOCKING] CRITICAL: 0
- [BLOCKING] HIGH: 0
- [BLOCKING] MEDIUM: 0

### Code You Touched
- [Should Fix] HIGH: 0
- [Should Fix] MEDIUM: 0

### Pre-existing
- [Informational] MEDIUM: 3 (major version updates available for vitest, @vitest/*, zod)
- [Informational] LOW: 7 (minor/patch updates available)

**Dependencies Score**: 9/10

The project has excellent dependency hygiene:
- No security vulnerabilities
- No unused dependencies
- No license conflicts
- No dependency conflicts
- All dependencies are actively maintained

**Merge Recommendation**: APPROVED

This branch introduces no dependency changes. The outdated packages are pre-existing and should be addressed in a separate maintenance PR focused on dependency updates.

---

## Recommended Follow-up Actions

1. **Separate PR**: Update minor/patch versions for production dependencies:
   ```bash
   npm update @modelcontextprotocol/sdk better-sqlite3 simple-git
   ```

2. **Separate PR with Testing**: Evaluate Vitest 4.x upgrade (breaking changes likely)

3. **Separate PR with Code Review**: Evaluate Zod 4.x upgrade (API changes likely)

4. **Optional**: Consider exact version pinning for production dependencies in package.json
