code-review

code-review is a skill for Claude Code, Codex from joelmnz/mcp-markdown-manager. It costs 19 tokens per session (1,315 once invoked), scanned A, original, MIT.

A project-specific checklist for reviewing code in the MCP Markdown Manager application, a TypeScript system for managing Markdown articles through web, API, and MCP interfaces.

In plain words
What is it for?
Use it during pull-request reviews to verify layering, imports, naming, error handling, database access, authentication, and test coverage.
Why use it?
It checks changes against the project's AGENTS.md rules for architecture, TypeScript, database safety, authentication, MCP behavior, and tests.

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-review 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 4d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What I Do

Enforce AGENTS.md rules during PR review (architecture layering, TypeScript discipline, DB safety, auth, MCP protocol, tests).

Core Checklist (Must Enforce)

Architecture / Boundaries

  • Layering: Routes/Handlers (routes/) → Service Facade (services/articles.ts) → DB Services (databaseArticles.ts, databaseVersionHistory.ts, databaseEmbedding.ts) → PostgreSQL
  • Single server: src/backend/server.ts handles API, MCP, and static serving
  • Routes = orchestration only (auth check → validate input → call service → format response)
  • Services throw descriptive errors; handlers catch and return HTTP status codes
  • Use the facade: handlers call articleService, never import DB services directly
  • Filenames are virtual: slug + .md (use slugToFilename / filenameToSlug)

TypeScript / Imports (CRITICAL)

  • Strict mode: no any, no @ts-ignore, no @ts-expect-error
  • Explicit interfaces for all data structures
  • ESM only with .ts extensions in imports (e.g., from './file.ts')
  • Node built-ins via bare specifiers (fs/promises, path)
  • Naming: camelCase functions/vars, PascalCase Components/Interfaces, SCREAMING_SNAKE_CASE constants
  • If you see type suppression: block the review until fixed

Database Operations

  • Parameterized queries only ($1, $2 placeholders) — never string interpolation in SQL
  • Connection pooling: use databaseService.getClient(), never create Pool instances
  • Always client.release() in finally blocks — no resource leaks
  • Wrap DB operations in try-catch, use handleDatabaseError()

Authentication & Security

  • All write endpoints: requireAuth(request, 'write') with scope check
  • All read endpoints: requireAuth(request) (read-only scope minimum)
  • Web-only endpoints (token management): useWebAuth: true
  • Bearer tokens: Authorization: Bearer <token> — never log full tokens
  • Input validation via mcp/validation.ts helpers
  • Path traversal prevention (no ../ in filenames/slugs)
  • DOMPurify for user content on frontend

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.
