Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions OpenCode.

This is oyi77/1ai-skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on 1ai-skills 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 1ai-skills 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

1ai-skills 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — 1ai-skills

MANDATORY PROCESS (8 Steps — No Skipping)

Every task follows this sequence. No exceptions.

  1. AUDIT — Read existing code. Understand current state.
  2. THINK — Understand WHY. Intent vs literal.
  3. BRAINSTORM — ≥3 approaches. Score options.
  4. PLAN — Decompose. Risks. Rollback plan.
  5. EXECUTE — Build. TDD when possible.
  6. TEST — Run all tests. Break it first.
  7. VERIFY — Prove with literal output.
  8. REVIEW — Read your own diff before committing.

This repo

Production-ready AI agent skill library — 1306 skills across 19 categories with anti-rationalization tables, code examples, and verification checklists. Stack: Node.js / Python / YAML skills Domain: Agent skill library — NOT a product repo. Do not add features here unless adding new skills.

Rules — thin loader, no submodule

Engineering rules are enforced by machine-level loaders when setup-dev.sh has been run:

  • Claude Code: SessionStart hook injects ~/.1ai/core/RULES.md
  • OpenCode: plugin injects ~/.1ai/core/RULES.md
  • OMP: wrapper appends ~/.1ai/core/RULES.md to launch sessions

Primary rules file:

cat ~/.1ai/core/RULES.md

Pre-ship gate:

cat ~/.1ai/core/GATE.md

What this repo is

1ai-skills provides domain-specific playbooks for AI agents. Each skill has:

  • YAML frontmatter (name, description, domain, tags)
  • Anti-Rationalization Table (prevents cutting corners)
  • Workflow (step-by-step)
  • Code examples (Python/JS/Bash)
  • Verification checklist

1ai-rules = HOW to code. 1ai-skills = WHAT to do.

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.
