agentmap: Instructions file for Codex

AGENTS.md

agentmap AGENTS.md is an instructions file for Codex, OpenCode from raymondchins/agentmap. It costs 1,163 tokens per session, scanned A, original, MIT.

Project instructions for agentmap, a public open-source package published to npm and an MCP registry. They define rules for code changes, releases, packaging, and the repository layout.

In plain words
What is it for?
Use them when editing the repository, preparing pull requests, adding runtime files, changing package contents, or creating a deliberate versioned release.
Why use it?
They prevent agents from bypassing the project's pull-request process, shipping unlisted files, or publishing releases accidentally.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is raymondchins/agentmap's own configuration. It tells Codex and OpenCode how to work on agentmap itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentmap configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/raymondchin/....

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

agentmap 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 1mo 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.

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

agentmap — Project Instructions

Auto-loaded every Claude Code session in this repo.

Universal rules live at ~/.claude/CLAUDE.md. This file = project-specific only.

⚠️ This is a PUBLIC OSS repo, not one of Ray's apps

Published to npm as @raymondchins/agentmap and to the MCP registry as io.github.raymondchins/agentmap. Consequences that override the usual defaults:

  • Code changes go through a PR, not a direct push. main is not branch-protected, so nothing stops you — the discipline is the point. CI (.github/workflows/ci.yml) runs on both PRs and pushes to main, so a direct push is still gated, just gated after the fact. Docs-only changes that touch no shipped file may go direct.
  • A release is a deliberate act. chore(release): X.Y.Z commits bump the version; the tag triggers publish. Don't bump the version as a side effect of a feature PR.
  • package.json files controls what ships. A new runtime file that isn't listed there is missing from the published tarball even though it works locally. Current list: agentmap.mjs, mcp.mjs, hooks, skills, .claude-plugin, server.json, NOTICE.
  • Assume strangers read the diff. No Ray-specific paths, no /Users/raymondchin/..., no internal project names in source or docs.

Read before editing

  1. CONTRIBUTING.md — the real rules live there: scope, the near-zero-deps rule, the freshness invariant, style, PR process. Read it, don't re-derive it from this file.
  2. README.md (50KB) — user-facing surface. The ## Commands section is the CLI contract.
  3. ROADMAP.md (96KB) + CHANGELOG.md (78KB) — history and intent. Check before proposing something already decided against.
  4. EVAL.md — the measured claims. Any number quoted in the README must be reproducible from eval/.

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.
