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

This is vincentkoc/dotskills's own configuration. It tells Codex and OpenCode how to work on dotskills 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 dotskills 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

dotskills 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 1mo 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.

Repository Purpose

This repository contains Codex, OpenClaw and other agentic AI skills and supporting references. Changes are scoped to skill definitions and lightweight workflow artifacts. Skills are managed using vercel-labs/agent-skills (skills.sh/docs).

Mandatory Contribution Flow

  1. Read CONTRIBUTING.md before making changes in this repo.
  2. Make targeted edits to skill files and references.
  3. Run validation gates before finalizing:
    • make validate
    • pre-commit run --all-files
    • make check-generated
    • if generated artifacts are out of date, run make marketplace && make releases-index and re-run make check-generated
  4. Open PRs as drafts first when applicable.

Skill Standards

  • Keep changes focused and minimal to requested scope.
  • Prefer deterministic commands and repeatable workflows.
  • Prefer concise, evidence-backed SKILL.md guidance.
  • Put operational details in references/ when they are verbose.
  • For public workflow charts and justified exemptions, follow CONTRIBUTING.md.
  • Public skills under skills/ must include license: MIT and metadata.source: https://github.com/vincentkoc/dotskills.
  • Validators must enforce public-skill license and source metadata.

OpenAI Metadata Defaults

Default values for agents/openai.yaml in public skills:

openai_yaml_defaults:
  interface:
    icon_small: "./assets/icon.jpg"
    icon_large: "./assets/icon.jpg"
    brand_color: "#111827"

New/Updated Skills Checklist

  • Update SKILL.md to keep required sections and concise workflow guidance.
  • Add or update references/, scripts/, and assets/ only when needed for reuse.
  • Public skills must include agents/openai.yaml with required interface fields and the defaults above.
  • Store per-skill icons in skills/<skill>/assets/icon.jpg and reference them via ./assets/icon.jpg.
  • If a public skill is added or renamed, update README.md public skills and install list.
  • If a public skill is added or renamed, update catalog.yaml entry.
  • Regenerate published indexes when public skills change: make marketplace and make releases-index.

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.
