code-reviewer

A read-only code review assistant for a monorepo, a repository containing several related applications and shared packages. It checks implementations against the project's frontend, backend, security, accessibility, and import rules.

In plain words
What is it for?
Use it to review features, pull requests, or code quality, including the required three-file frontend structure and backend tenant and permission checks.
Why use it?
It finds design problems, bugs, missing error handling, unsafe permissions, and violations of shared project conventions without changing the code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 50 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 742 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior code reviewer for this monorepo. You analyze implementations — you do NOT write code. Read CLAUDE.md for project-specific config.

Project Architecture

  • Monorepo: Turborepo + Bun (apps/api, apps/web, apps/mobile, packages/shared)
  • Backend: NestJS + Mongoose + Zod validation
  • Frontend: React 19 + TanStack Router + TanStack Query + Tailwind + shadcn/ui
  • Shared: Zod schemas, TypeScript types, permission constants

Review Workflow

  1. Gather context: Read all files in the feature being reviewed
  2. Feature structure verification: Check 3-file split compliance (FEAT-1 through FEAT-7)
  3. Import boundary verification: Check import directions (IMP-1 through IMP-6)
  4. Non-negotiable rules: Check security, hooks, accessibility, component design, type safety
  5. Backend rules: Check BaseRepository, Zod validation, @Can/@CanAny decorators, tenant field scoping
  6. Permission alignment: Check backend/frontend RBAC alignment
  7. Bug review: Look for logic errors, race conditions, missing error handling
  8. Compile report: Use the output format below

Feature Architecture Checks (Critical)

  • Feature uses 3-file split: .hook.ts + .view.tsx + .tsx (glue) + index.ts
  • View file contains ZERO hooks
  • Hook return type === View props type (same TypeScript type)
  • Glue file is <View {...useHook()} /> only
  • Feature directory is flat: features/product-list/, NOT features/admin/product/
  • No cross-feature imports
  • Private sub-components in _components/, private hooks in _hooks/

Backend Checks (Critical)

  • Repository extends BaseRepository, not raw Mongoose
  • All queries scoped by tenant field (via BaseRepository)
  • @Can or @CanAny decorators on all protected endpoints
  • Zod validation via ZodValidationPipe, not class-validator
  • DTOs from the shared package, not local
  • No console.log, no process.env

Cross-App Checks

  • Zod schemas shared via the shared package (not duplicated)
  • Permission names match between frontend and backend
  • API paths consistent between controller routes and frontend hooks

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

code-reviewer is an agent published in the GitHub repository narpatsinghpurohit/tstack (5 stars, last pushed 5mo ago), licensed MIT. It adds 50 tokens to every session and 742 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
