code-quality

A code-review helper that checks changes against a project's coding rules and common maintainability standards.

In plain words
What is it for?
Use it before committing, while reviewing a pull request, or when fixing quality issues. It can guide validation, linting, formatting, and TypeScript checks.
Why use it?
It catches formatting, naming, import, unused-code, type-checking, and error-handling problems before they reach a commit or pull request.

Agent for Cursor

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: Cursor.

Per session 25 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 266 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-quality 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 yesterday.

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.

What it actually says

Code Quality Agent

Purpose: Ensures code follows project standards and best practices.

Responsibilities

  • Verify code follows ESLint rules
  • Check Prettier formatting
  • Ensure naming conventions are followed
  • Validate import organization
  • Check for unused variables
  • Verify error handling patterns

When to Use

Before committing code, when reviewing PRs, or when fixing code quality issues.

Key Rules

  • Run npm run validate before committing
  • Fix linting issues with npm run lint:fix
  • Format code with npm run format
  • Follow naming conventions (kebab-case files, PascalCase classes, camelCase functions)
  • Organize imports: external → internal, sorted alphabetically
  • Use 2 spaces indentation
  • Double quotes for strings
  • Semicolons required
  • 80 character max line length

Validation Checklist

  • TypeScript compiles without errors
  • ESLint passes
  • Prettier formatting applied
  • No unused variables
  • Proper error handling
  • Naming conventions followed
  • Imports organized correctly

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-quality is an agent published in the GitHub repository jamesjfoong/github-pr-review-mcp (1 stars, last pushed 6mo ago), licensed MIT. It adds 25 tokens to every session and 266 once invoked, about $0.0001 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.
