402-mcp AGENTS.md

402-mcp AGENTS.md is an instructions file for Codex, OpenCode from forgesworn/402-mcp. It costs 235 tokens per session, scanned A, original, MIT.

Project instructions for AI coding agents working on the 402-mcp codebase. AGENTS.md is a file that tells coding tools how a project is built, tested, structured, and written.

In plain words
What is it for?
It helps agents build the project, run Vitest tests, check TypeScript types, follow its file structure and coding conventions, and apply its security patterns.
Why use it?
It gives an agent the project rules and commands it needs to make changes that fit the existing codebase.

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

402-mcp AGENTS.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 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.

What it actually says

AI Agent Instructions

This project uses CLAUDE.md as the primary source of AI agent instructions. It covers:

  • Build, test, and typecheck commands
  • Project structure and conventions
  • Security patterns and rationale
  • Dependency API notes (cashu-ts v2, @forgesworn/nwc-kit, farrier-kit)
  • Testing conventions (handler extraction, mock injection)

All AI coding agents (Cursor, Copilot, Gemini, etc.) should read CLAUDE.md for project context.

Quick reference

npm run build       # tsc → build/
npm test            # vitest run
npm run typecheck   # tsc --noEmit
  • British English — colour, initialise, behaviour, licence
  • ESM-only"type": "module", target ES2022, module Node16
  • Tool pattern — each tool exports handle* (testable) + register*Tool (MCP wiring)
  • Tests live in tests/, not co-located with source
Changes

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.
