easy-cheese: Instructions file for Codex

AGENTS.md

easy-cheese AGENTS.md is an instructions file for Codex, OpenCode from paulnsorensen/easy-cheese. It costs 1,633 tokens per session, scanned A, original, MIT.

Development instructions for easy-cheese, a collection of reusable instructions for coding agents, with one required quality-check command.

In plain words
What is it for?
Use them when changing a skill, its Python or shell support, documentation, or build configuration, and run `just check` before declaring success.
Why use it?
They provide a single way to check formatting, tests, builds, shell scripts, and instruction files before work is handed over.

Written for Codex and OpenCode: the file is AGENTS.md.

This is paulnsorensen/easy-cheese's own configuration. It tells Codex and OpenCode how to work on easy-cheese 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 easy-cheese 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

easy-cheese 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 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.

Agent Instructions for easy-cheese

This document is for LLMs, agents, and automation tools working in this repository.

Single Quality Gate: just check

Always run just check before declaring work done — before any commit, push, PR open, or hand-off. Treat green from just check as the only signal that a change is shippable.

just check autofixes lint (markdown, yaml, python via ruff) and runs the full local build: skill frontmatter validation (validate_skills.py), shell lint, python + bash test suites, and mkdocs build --strict. CI runs just ci (same checks, no autofixes).

just check

Do NOT commit or push when just check fails. If CI fails, pull the branch locally, run just check, commit the autofixes, and push.

Prerequisites

  • just — recipe runner
  • uvlint-py-fix invokes uvx ruff (no global ruff install needed)
  • yamllint, yamlfmt, markdownlint-cli2, shellcheck, bats — see README for install hints

Skills in this repo

This is a skills-only collection following the Agent Skills spec. Every change either adds, edits, or supports a skill under skills/<name>/.

Skill Python bundle doctrine

This is the target contract. Existing violations are migration work; do not expand them while enforcement is implemented separately.

  • A skill that executes Python ships exactly skills/<skill>/scripts/<skill>.pyz; a skill with no Python ships no .pyz. Skill prose invokes only its own archive—never loose source, common.pyz, repository automation, or another skill's bundle.
  • Runtime Python lives under src/. Tests remain under tests/; repository build, release, generation, and maintenance programs may live under scripts/.
  • Published schemas live in src/easy_cheese_schemas/. All non-published runtime code lives under src/easy_cheese/, split between skills/<python_skill_name>/ and shared/. Skill slugs remain kebab-case; Python package segments use underscores.
  • Bundles may contain Python modules, bytecode, and immutable package resources. Dependencies must be pure Python and zip-importable. Native extensions, platform-specific libraries, required external executables, runtime installation/downloads, and caller-managed extraction are prohibited. Shiv's transparent cache extraction is part of the archive runtime contract.
  • Each bundle contains its entrypoints and metadata-resolved runtime closure: one skill distribution, the cohesive internal shared distribution, schemas, and approved pure-Python dependencies. Other skill distributions are excluded.
  • Checked-in .pyz files are generated deployment artifacts, never source of truth. Python source never lives under skills/.

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.
