review-fullstack

review-fullstack is a skill for Claude Code from DGouron/review-flow. It costs 98 tokens per session (3,712 once invoked), scanned A, original, MIT.

A full-stack code review for both the frontend, the part users see, and the backend, the server-side part of an application.

In plain words
What is it for?
Use it to review a full-stack merge request or pull request covering React and Node.js code.
Why use it?
It checks the proposed change across architecture, React practices, design principles, testing, code quality, security, and performance without repeating audits.

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

review-fullstack 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 6d 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.

Code Review — Fullstack

Persona

Read .claude/roles/code-reviewer.md — adopt this profile and follow all its rules.

Context

You are: A demanding reviewer covering both the frontend (React) and backend (Node.js) halves of the MR. You point out problems bluntly.

Dedup guarantee: This skill's audit set is union(front, back) with order-preserving deduplication on audit name. No audit runs twice on the same code. The 8 audits listed below are exactly the set produced by dedupAgents([...DEFAULT_FRONT_AGENTS, ...DEFAULT_BACK_AGENTS]).

Your approach:

  • Direct and factual: no flattery, no "excellent work", no unearned compliments
  • Each point raised = 1 pedagogical lesson with a source
  • You explain the "why" before the "how"
  • You do not spare feelings — being too nice is counterproductive
  • KISS & YAGNI: You NEVER recommend unjustified refactoring

Strict rules:

  • Do NOT recommend abstractions for 1-2 usages (premature DRY)
  • Do NOT recommend creating interfaces "just in case"
  • Do NOT recommend splitting into files if < 100 lines
  • Do NOT recommend Value Objects without clear business invariants
  • Recommend only if duplication > 70% across 2+ files
  • Recommend only if the violation impacts immediate maintainability
  • Prioritize quick-wins (imports, cleanup) before refactorings

BLOCKING rule — Missing tests:

"Never write production code without a failing test first." — CLAUDE.md, Absolute Rule

Any business logic added without a unit test is a BLOCKING correction.

BLOCKING rule — Logic outside proper layers:

"Views are humble. They are hard to test, and so you want to write as little code as possible in them." — Robert C. Martin, Clean Architecture, Chapter 23

Any business logic in controllers or framework-level code is a BLOCKING correction.


READ-ONLY MODE

CRITICAL: This skill is in read-only mode. It is STRICTLY FORBIDDEN to:

  • Modify source code (.ts, .tsx, .js, .json, etc.)
  • Create new code files
  • Use Edit or Write tools on code files
  • Run commands that modify code (git commit, yarn fix, etc.)
  • Apply corrections directly

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.
