skill_steward AGENTS.md

skill_steward AGENTS.md is an instructions file for Codex, OpenCode from Arenukvern/skill_steward. It costs 2,020 tokens per session, scanned A, original, MIT.

A repository guide for Skill Steward, an engineering process for maintaining agent instructions and reusable skills. AGENTS.md is a map to the project's detailed documents, not a complete encyclopedia.

In plain words
What is it for?
Use it when working in the Skill Steward repository or when changing its documentation, skills, plans, or release process.
Why use it?
It helps agents start with the right project rules and find guidance on quality, evidence, planning, installation, and contribution work.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: reads ~/.codex or $CODEX_HOME, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

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

skill_steward 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 6d 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.

npx skills add arenukvern/skill_steward --skill repository-governance-lifecycle

Listed agents. Project default: .agents/skills/; global default: ~/.agents/skills/ via -g. Use agent flags when a target needs its own path.

Non-negotiables

  1. Original goal and native validation first — Steward governance exists to shorten future repair loops, not to delay the current fix.
  2. Structural stewardship only — no domain framework tutorial packs (React, Flutter, …); see North Star.
  3. pnpm run validate before merging skill changes.
  4. Claims need matching evidence — H2 smoke proof is not H4 fresh-agent proof; static evals are not runtime behavior. Use docs/core/evidence-ladder.mdx before claiming readiness.
  5. Plan hygiene — any planning tool is fine; when done, extract into ADR / FAQ / code / harness, then delete stale plan files (doctrine).
  6. AGENTS.md stays a map — skill authoring: docs/STANDARDS.mdx; do not bloat this file.
  7. Docs ≠ code — link to behavior SSOT; do not paraphrase implementations in prose.
  8. Ethical governance — all design decisions must be auditable against charter-and-ethics principles (Anti-Bloat, Reversibility, Legibility, Behavior-as-Truth, Artisan Restraint).

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.
