AGENTS.md

genie AGENTS.md is an instructions file for Codex, OpenCode from automagik-dev/genie. It costs 2,508 tokens per session, scanned A, original, MIT.

A shared contributor guide for Genie, a command-line tool that manages repository tasks and related state.

In plain words
What is it for?
Use it when developing Genie, running its checks and tests, changing hooks or commands, or working with its per-project and global task databases.
Why use it?
It explains where code and databases belong, which checks changes must pass, and how Claude Code, Codex, and people should work together.

Instructions file for CodexOpenCode

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

This is automagik-dev/genie's own configuration. It tells Codex and OpenCode how to work on genie 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 genie configures →

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

genie 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 25d 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.

Genie repository contract

This is the runtime-neutral contributor contract for Claude Code, Codex, and human contributors. Client-specific overlays may add syntax, but they must not contradict this file.

Validate changes

bun install --frozen-lockfile
bun run check
bun test path/to/file.test.ts

The full gate runs type checking, Biome, dead-code analysis, skill/wish/council linting, and tests. Tests use bun:test; fixtures belong under a temporary directory and must isolate GENIE_HOME when touching global state.

Architecture

  • src/genie.ts is the Commander CLI entry point.
  • src/lib/v5/ owns SQLite state. The per-repo .genie/genie.db stores task state and is the only database genie writes; the machine-scope ~/.genie/genie.db path carries no genie state in v6, and the per-repo opener refuses it so the two can never merge.
  • src/term-commands/ owns init, context, MCP, task, and board commands.
  • plugins/genie/ is retired with the Orca integration: the source tree carries none, and release tarballs keep an empty plugins/genie/ compat directory only because earlier binaries' update path requires it. genie orca is a one-release stub that prints a retirement notice and exits 2.
  • skills/ is shared runtime-neutral workflow guidance, delivered to every agent home by the skills channel. genie install/genie update run the pinned skills.sh CLI over the local delivered tree and record the result in <GENIE_HOME>/skills-install.json; without the Genie binary the same skills install with npx skills add automagik-dev/genie, which serves the repository's default branch rather than a release.
  • .genie/ contains git-tracked wishes, reviewed designs (brainstorms/*/DESIGN.md) and the index, plus gitignored brainstorm working notes and operational SQLite files.

Genie is zero-daemon: every command is fork-and-exit and there is no resident process, optional or otherwise. Do not use telemetry presence as integration health.

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.
