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:

# 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):

npm install

Wait for install to complete before proceeding.

0.2 Docker Containers

Check if required containers are running:

docker ps --filter name=well_ --format "{{.Names}}: {{.Status}}"

Expected: well_postgres and well_hasura running

If not running (auto-resolve):

cd 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:

cd 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)

curl -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:
```
lsof -ti :8080 | xargs kill -9 2>/dev/null
```
Then prompt user to restart: cd apps/api && npm run dev

0.5 Web Server (port 3000)

curl -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:
```
lsof -ti :3000 | xargs kill -9 2>/dev/null
```
Then prompt user to restart: cd apps/web && npm run dev

0.6 Build Cache (on error only)

If typecheck passes but runtime errors occur (module not found, stale code):

npm run clean

Then prompt user to restart dev servers.

0.7 Runtime Check Output

### 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

npm run typecheck

Expected: Exit code 0, no errors

1.2 Lint Check

npm 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

## PR Review Report

### 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/killed/skipped] |
| Web Server (3000) | UP/DOWN/STALE | [running/killed/skipped] |

**Runtime:** [READY / WAITING]

### Technical Validation

| Check | Status | Details |
|-------|--------|---------|
| TypeCheck | PASS/FAIL | [error count or "clean"] |
| Lint | PASS/FAIL | [error count or "clean"] |
| ReadLints | PASS/WARN/FAIL | [summary] |

### Code Quality

| Check | Status | Count | Files |
|-------|--------|-------|-------|
| console.log | PASS/WARN | [N] | [files] |
| TODO/FIXME | PASS/INFO | [N] | [files] |
| Hardcoded | PASS/WARN | [N] | [files] |

### Risk Assessment

| Factor | Score |
|--------|-------|
| Lines Changed | [N] |
| Files Changed | [N] |
| New Dependencies | [N] |
| API Changes | [N] |
| Database Changes | [N] |
| **Total Risk** | [N] ([LOW/MEDIUM/HIGH]) |

### Verdict

**[PASS / WARN / BLOCK]**

[If BLOCK: List issues that must be fixed]
[If WARN: List issues that should be addressed]
[If PASS: Ready to commit]

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 commit
push-pr.mdc - Phase 1.1 validation
agent.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:

## 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.
