PR Review Skill
Automated technical validation before commits. Uses ReadLints for lint/type errors and Shell for running validation commands.
When to Use
- Before every commit (invoked by commit.mdc)
- Before pushing PR (invoked by push-pr.mdc Phase 1)
- Manually with "use pr-review skill"
Phase 0: Runtime Check (Auto-Resolve)
Verify development environment is ready. Auto-resolve safe issues, prompt for risky ones.
0.1 Dependencies Check
Check if dependencies are fresh:
bash# Check if node_modules exists ls -d node_modules 2>/dev/null # Check if package-lock.json is newer than node_modules find package-lock.json -newer node_modules 2>/dev/null
If node_modules missing or stale (auto-resolve):
bashnpm install
Wait for install to complete before proceeding.
0.2 Docker Containers
Check if required containers are running:
bashdocker ps --filter name=well_ --format "{{.Names}}: {{.Status}}"
Expected: well_postgres and well_hasura running
If not running (auto-resolve):
bashcd apps/api/docker && docker compose up -d
Wait up to 30 seconds for containers to be healthy.
0.3 Database Migrations
Check for pending migrations:
bashcd apps/api && npm run mikro:up -- --dry-run 2>&1 | head -5
If migrations pending (WARN - do NOT auto-run):
Database migrations may be pending. Run manually if needed: cd apps/api && npm run mikro:up Continue without running migrations? (y/n)
Wait for user confirmation before proceeding.
0.4 API Server (port 8080)
bashcurl -s -o /dev/null -w "%{http_code}" http://localhost:8080/health --max-time 5
Expected: HTTP 200
If not responding:
- Check if process exists:
lsof -i :8080 - If NO process, prompt user to start:
API server not running on port 8080. Start with: npm run dev (in apps/api) - If process EXISTS but unresponsive, ASK user:
API server on port 8080 is unresponsive (process exists but not responding). Options: A) Kill process and restart (recommended) B) Skip and continue anyway C) Abort commit Reply with A, B, or C. - If user chooses A:
Then prompt user to restart:bashlsof -ti :8080 | xargs kill -9 2>/dev/nullcd apps/api && npm run dev
0.5 Web Server (port 3000)
bashcurl -s -o /dev/null -w "%{http_code}" http://localhost:3000 --max-time 5
Expected: HTTP 200
If not responding:
- Check if process exists:
lsof -i :3000 - If NO process, prompt user to start:
Web server not running on port 3000. Start with: npm run dev (in apps/web) - If process EXISTS but unresponsive, ASK user:
Web server on port 3000 is unresponsive (process exists but not responding). Options: A) Kill process and restart (recommended) B) Skip and continue anyway C) Abort commit Reply with A, B, or C. - If user chooses A:
Then prompt user to restart:bashlsof -ti :3000 | xargs kill -9 2>/dev/nullcd apps/web && npm run dev
0.6 Build Cache (on error only)
If typecheck passes but runtime errors occur (module not found, stale code):
bashnpm run clean
Then prompt user to restart dev servers.
0.7 Runtime Check Output
markdown### Runtime Environment | Service | Status | Action | |---------|--------|--------| | Dependencies | FRESH/STALE | [installed/skipped] | | Docker (postgres) | UP/DOWN | [started/already running] | | Docker (hasura) | UP/DOWN | [started/already running] | | Migrations | CURRENT/PENDING | [warning shown/current] | | API Server (8080) | UP/DOWN/STALE | [running/started/killed/skipped] | | Web Server (3000) | UP/DOWN/STALE | [running/started/killed/skipped] | **Runtime:** [READY / WAITING - user action needed]
If any service requires manual action, wait for user confirmation before proceeding.
Phase 1: Technical Validation
1.1 Type Check
bashnpm run typecheck
Expected: Exit code 0, no errors
1.2 Lint Check
bashnpm run lint
Expected: Exit code 0, no errors
1.3 ReadLints Integration
Use Cursor's ReadLints tool on changed files:
ReadLints: paths: [list of changed files]
Categorize results:
| Severity | Action |
|---|---|
| Error | BLOCK - must fix before commit |
| Warning | WARN - should fix, can proceed |
| Info | PASS - informational only |
Phase 2: Code Quality Checks
2.1 Console.log Detection
Search changed files for debug statements:
Grep: pattern: "console\.(log|debug|warn|error)" path: [changed files]
If found: WARN - remove before commit
2.2 TODO/FIXME Detection
Grep: pattern: "(TODO|FIXME|HACK|XXX):" path: [changed files]
If found: INFO - document or address
2.3 Hardcoded Values
Grep: pattern: "(localhost|127\.0\.0\.1|hardcoded)" path: [changed files]
If found: WARN - use environment variables
Phase 3: Risk Assessment
Calculate risk score based on:
| Factor | Weight | Criteria |
|---|---|---|
| Lines Changed | 1-3 | <50=1, 50-200=2, >200=3 |
| Files Changed | 1-3 | <5=1, 5-10=2, >10=3 |
| New Dependencies | 0-2 | None=0, 1=1, >1=2 |
| API Changes | 0-2 | None=0, Internal=1, Public=2 |
| Database Changes | 0-2 | None=0, Field=1, Entity=2 |
Risk Levels:
- LOW (0-4): Standard review
- MEDIUM (5-8): Careful review
- HIGH (9+): Thorough review recommended

Verdict Logic
| Condition | Verdict |
|---|---|
| Runtime WAITING (user action needed) | BLOCK |
| User chose C (Abort) for stale server | BLOCK |
| Dependencies installed | Continue (auto-resolved) |
| Migrations pending | WARN (can proceed after confirmation) |
| Server killed by user (chose A) | Continue after user restarts |
| TypeCheck FAIL or Lint FAIL | BLOCK |
| ReadLints has Errors | BLOCK |
| console.log found | WARN |
| Risk >= HIGH | WARN |
| All checks pass | PASS |
Integration
This skill is invoked by:
commit.mdc- Before each commitpush-pr.mdc- Phase 1.1 validationagent.mdc- Part of commit-level workflow
Tools Used
| Tool | Purpose |
|---|---|
| Shell | Run npm scripts (typecheck, lint) |
| ReadLints | Get IDE diagnostic errors |
| Grep | Search for patterns in code |
| Read | Examine specific file contents |
Quick Mode
For rapid iteration, run minimal checks:
markdown## Quick Review - [ ] `npm run typecheck` - PASS - [ ] `npm run lint` - PASS - [ ] No console.log - PASS **Verdict:** PASS - Ready to commit
Use full review before PR push; quick mode acceptable for intermediate commits.
