configure-agents: Instructions file for Codex

AGENTS.md

configure-agents AGENTS.md is an instructions file for Codex, OpenCode from gleanwork/configure-agents. It costs 380 tokens per session, scanned A, original, MIT.

Instructions for `gleanwork/configure-agents`, a command-line tool that creates and checks standard agent instruction files in software projects. It covers development commands and the files that define the standard.

In plain words
What is it for?
Use them when developing the CLI, changing its baseline agent files, or running its setup and consistency checks.
Why use it?
They help contributors build, test, and update the tool without changing its templates and validation rules inconsistently.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; mentions Codex.

This is gleanwork/configure-agents's own configuration. It tells Codex and OpenCode how to work on configure-agents 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 configure-agents 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

configure-agents 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 23d 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

AGENTS.md

Agent instructions for @gleanwork/configure-agents — the CLI that scaffolds and drift-checks the gleanwork agent baseline (AGENTS.md, CLAUDE.md, skills/) across library and SDK repos.

Development

  • Install: npm install
  • Build: npm run build (compiles src/ to build/, then copies templates)
  • Test: npm test (vitest)
  • Checks: npm run lint, npm run lint:ts, npm run format
  • Run locally: npm run go -- init / npm run go -- check, or node build/index.js <command> after a build

This is an ESM project with module: nodenext, so relative imports use .js extensions even though the files are .ts.

The review module (configure-agents review) lives in src/review/. Its permission presets and Codex compiler in src/review/permissions.ts match the runtime copy in the scalvert agent plugin. test/fixtures/presets.json and test/fixtures/draft-pr.rules pin that shared contract, so change both repos together.

The single source of truth for the baseline is src/baseline/spec.ts. init writes the baseline and check enforces it from the same lists — change them together. Scaffold templates live in src/init/templates/files/ and are copied into build/ at build time.

Skills

skills/configure-agents/SKILL.md is the authoring rubric — a skill for authoring library skills — distributed via skills.sh. It is the rubric, not a library skill, so the drift check is intentionally not self-applied to this repo.

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.
