skillcraft: Instructions file for Codex

AGENTS.md

skillcraft AGENTS.md is an instructions file for Codex, OpenCode from cloudroad-io/skillcraft. It costs 959 tokens per session, scanned A, original, MIT.

Repository instructions for skillcraft, a tool that manages agent configuration files such as AGENTS.md, SKILL.md, and Claude or Copilot rules. It can lint these files, generate related versions from one canonical source, and detect differences.

In plain words
What is it for?
Use it to initialize a configuration project, lint instruction files, synchronize managed targets, check for drift, and inspect the tool's version.
Why use it?
It helps keep configuration instructions consistent across different AI coding tools. A shared AGENTS.md source and drift checks reduce conflicting or outdated copies.

Instructions file for CodexOpenCode

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

This is cloudroad-io/skillcraft's own configuration. It tells Codex and OpenCode how to work on skillcraft 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 skillcraft 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

skillcraft 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 2mo 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.

skillcraft

ESLint + Jest for agent-config files. skillcraft lints, syncs and scaffolds the fragmented ecosystem of SKILL.md, CLAUDE.md, AGENTS.md, .cursor/rules, .claude/rules and copilot-instructions. One canonical source, many managed targets, drift detection in CI.

Install

uv tool install skillcraft
# or: pip install skillcraft

Commands

Command Purpose
skillcraft lint [--check] [-f plain|json|github|sarif] Run the rule set over discovered config files; exit 1 on any ERROR.
skillcraft sync [--check] [--diff] [--adopt <file>] Regenerate managed targets from AGENTS.md; detect drift.
skillcraft init [--name <name>] Scaffold a minimal AGENTS.md + .skillcraft.toml.
skillcraft version Print the version.

How it works

  • Canonical source = AGENTS.md (vendor-neutral, schema-less). Richer metadata (name, description, scope, license, …) rides in invisible <!-- skillcraft:meta <json> --> comments — valid markdown to every consumer, machine-readable to skillcraft.
  • IR: ConfigDoc. Every parser emits it, every renderer consumes it. Same-format parse→render is lossless; extra_frontmatter escape hatch guarantees no field is silently dropped.
  • Sync. skillcraft sync renders each target from the canonical doc and writes it with a <!-- skillcraft:managed-source path=AGENTS.md --> marker. skillcraft sync --check exits 1 if any managed target drifted (CI). Unmanaged files are never overwritten; opt in with --adopt.
  • Plugins. Subclass Rule or Converter, decorate with @register_rule / @register_converter, and (for external packages) declare an entry-point in skillcraft.rules / skillcraft.converters. See CONTRIBUTING.md.

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.
