code-auditor-mcp CLAUDE.md

code-auditor-mcp CLAUDE.md is an instructions file for coding agents from BenAHammond/code-auditor-mcp. It costs 1,655 tokens per session, scanned A, original, MIT.

Development instructions for Code Auditor, a tool that checks code changes against architectural and quality rules.

In plain words
What is it for?
Use it to map a codebase, audit changed files, run the command-line tool or MCP server, and maintain its analyzers and integrations.
Why use it?
It helps an agent understand how to run the project, build it, test it, and audit only the code affected by a change.

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.

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-auditor-mcp CLAUDE.md 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 today.

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.

Commands

Development

cd app
npm run dev          # Run CLI in dev mode (tsx src/cli.ts)
npm run dev:server   # Run MCP server with watch mode
npm run dev:mcp      # Run MCP server directly
npm run watch        # Watch TypeScript compilation

Building

cd app
npm run build        # Compile TypeScript to dist/ + copy WASM grammars

Testing

cd app
npm run test         # Run Vitest tests
npm run test:watch   # Run tests in watch mode
npx vitest run path/to/test.spec.ts  # Run specific test file

Running the Tool

cd app
npm run audit        # Run audit tool (after build)
npm run start        # Start MCP server
node dist/cli.js changed --json  # Diff-scoped audit
node dist/cli.js map -p .        # Codebase map

Architecture Overview

Code Auditor enforces architectural invariants and code quality rules inside an AI agent's edit loop. It integrates with Claude via Model Context Protocol (MCP), a CLI, and a Claude Code plugin.

Core Components

  1. Analyzers (app/src/analyzers/)

    • Functional pattern: each analyzer is a function returning arrays of violations
    • Analyzers process tree-sitter ASTs via adapterBridge.ts
    • Current analyzers: SOLID, DRY, data access, React, documentation, schema, invariants

  2. Language Layer (app/src/languages/)

    • LanguageAdapter interface (23 methods) — the single seam for language support
    • adapterBridge.ts — synchronous facade over tree-sitter parsers
    • tree-sitter/parser.ts — web-tree-sitter WASM loader (initParsers(), getParser())
    • LanguageRegistry — singleton; adapters registered by initializeLanguages()
    • Two-phase init: initializeLanguages() (sync, registers adapters) then initParsers() (async, loads WASM grammars). Both required before any parsing.
    • Adapters: TreeSitterTypeScriptAdapter (.ts/.tsx/.js/.jsx), TreeSitterGoAdapter (.go)
    • WASM grammars at dist/grammars/ — shipped in the npm package; zero native compilation

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.
