Project Checker
Automatically build, test, and review the 9Router project.
Workflow
Follow this exact sequence:
1. Run Build
npm run build
Check for any build errors. Report success or failure immediately.
2. Run Lint (if requested or on commit)
npx eslint . 2>&1 | head -50
Report lint errors if any.
3. Run Tests
npx vitest run
Report test results - passed/failed counts.
4. Review Changes (if git changes exist)
Check for uncommitted or unpushed changes:
git status --short
git diff --cached
git diff
Review the changes following these guidelines:
- Bugs: Logic errors, off-by-one, incorrect conditionals, null/empty/undefined handling
- Security: Injection, auth bypass, data exposure
- Structure: Does code follow existing patterns? Are there established abstractions?
- Performance: Flag if obviously problematic (O(n²), N+1 queries)
- Behavior Changes: Note if changes alter existing behavior
5. Provide Report
Format the report as:
## Project Check Results
### Build: ✅ PASS / ❌ FAIL
[summary]
### Lint: ✅ PASS / ⚠️ WARNINGS / ❌ ERRORS
[count and key issues if any]
### Tests: ✅ PASS (X/Y) / ❌ FAIL (X/Y)
[failed tests if any]
### Code Review:
[for each file changed]
- **File**: filename
- **Issues**: [list issues found with severity: HIGH/MEDIUM/LOW]
- **Notes**: [behavioral changes, if any]
## Summary
[overall assessment]
Severity Guidelines
- HIGH: Security vulnerability, data loss, complete breakage
- MEDIUM: Feature broken, partial failure, missing router.refresh()
- LOW: Code style, minor improvement, silent error swallowing
Error Handling
If any step fails:
- Report the failure immediately with error message
- Do NOT continue to next steps
- Ask user if they want to fix before continuing
Context
This project uses:
- Next.js 16 with App Router
- Vitest for testing
- ESLint for linting
- lowdb + better-sqlite3 for data persistence
- JWT auth with httpOnly cookies
