Code Review: /review & /ultrareview

RugvAI Labs

Command	Speed	Depth	Cost	Best For
`/review`	~30s	Single-agent pass	Local model tokens	Pre-commit sanity check on uncommitted changes
`/ultrareview`	2–5 min	Multi-agent fanout (security, perf, tests, style)	Billed cloud run	Pre-PR or pre-merge — production-grade

🟡 src/api/auth.py:42 — SQL string concatenation; use parameterized query
🟢 src/api/auth.py:68 — Magic constant 86400; consider TOKEN_TTL_SECONDS
🟢 tests/auth.py — Missing test for expired-token path

No critical issues. 3 suggestions.

> /review --staged           # only review staged changes
> /review src/auth/          # only review files in src/auth/
> /review --since main       # review everything since branching from main
> /review --focus security   # focus on security issues only

1. Bundle the diff (current branch vs base, OR fetch PR #N)
2. Spawn parallel cloud agents:
   - security-reviewer    (auth, secrets, injection, OWASP)
   - performance-reviewer (N+1, big-O, blocking I/O, allocations)
   - test-reviewer        (coverage, edge cases, missing assertions)
   - style-reviewer       (project conventions, CLAUDE.md compliance)
   - architecture-reviewer (layering, module boundaries, abstractions)
4. Each agent reads relevant files for context (not just the diff)
5. Synthesizer agent merges findings, dedupes, ranks by severity
6. Outputs unified report + (optional) GitHub PR comment

ULTRAREVIEW — feat/auth-google (12 files, +487 -128)

🔴 CRITICAL (2)
  src/api/auth.py:42  — SQL injection: f-string in WHERE clause
  src/api/auth.py:101 — JWT verified without checking expiry

🟡 MAJOR (4)
  src/api/auth.py:68    — Token TTL hardcoded; use config
  src/api/auth.py:155   — Missing rate limit on /callback endpoint
  tests/auth.py:23      — No test for expired-token branch
  src/db/users.py:12    — N+1: get_user_with_roles loops queries

🟢 MINOR (7)
  ... (style, naming, doc improvements)

OVERALL: 2 blockers, 4 should-fix, 7 nits.
Recommendation: BLOCK merge until critical issues resolved.

# Code Review Guidelines

## Severity Bar
- CRITICAL: blocks merge — security, data loss, public API breakage
- MAJOR: should fix — bugs, missing tests, performance regressions
- MINOR: nits — naming, comments, formatting

## Project-Specific Rules
- All API endpoints must have rate limiting (use @rate_limit decorator)
- Database queries must use parameterized statements (no f-strings in SQL)
- React components must handle prefers-reduced-motion
- TypeScript strict mode — no `any`
- All public functions need JSDoc

## Skip
- Don't flag prettier formatting (CI handles it)
- Don't suggest renaming variables to match a different convention
- Don't recommend abstraction unless the duplication exceeds 3 places

## Tests
- Coverage minimum: 80% on new code
- Every new endpoint needs at least: happy path, auth failure, validation failure

> /review --since main --focus security
   ↳ security-only review of full branch

> /ultrareview --skip style
   ↳ skip the style agent (saves cloud cost on draft PRs)

> /ultrareview 142 --post-comment
   ↳ post the synthesized review as a GitHub PR comment

> /review --diff-only
   ↳ skip context fetching; only look at diff (fastest, less accurate)
