A meta-skill for turning scattered documentation, API details, code, or specifications into a reusable coding-agent skill.

Use it to create or improve a skill, define when it should activate, split long material into references, and add validation or quality gates.

It helps organize specialist knowledge into clear instructions, supporting references, examples, and checks instead of leaving it fragmented.

auto-skill — Skill for Claude Code and Codex by ziiyuecheng

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/ziiyuecheng/vibe-coding-cn

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.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.02368
Opus 5	$0.00024	$0.01184
Sonnet 5	$0.00010	$0.00474
Haiku 4.5	$0.00005	$0.00237

Security

Grade A, and why

auto-skill 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 9d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/create-skill.sh, scripts/skill-seekers-bootstrap.sh, scripts/skill-seekers-import.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Auto Skill

Turn scattered domain material into a Skill that is reusable, maintainable, and reliably activatable:

SKILL.md as the entrypoint (triggers, constraints, patterns, examples)
references/ for long-form evidence and navigation
optional scripts/ and assets/ for scaffolding and templates

When to Use This Skill

Trigger this meta-skill when you need to:

Create a new Skill from scratch from docs/specs/repos
Refactor an existing Skill (too long, unclear, inconsistent, misfires)
Design reliable activation (frontmatter + triggers + boundaries)
Extract a clean Quick Reference from large material
Split long content into navigable references/
Add a quality gate and a validator

Not For / Boundaries

This meta-skill is NOT:

A domain Skill by itself (it builds domain Skills)
A license to invent external facts (if the material does not prove it, say so and add a verification path)
A substitute for required inputs (if inputs are missing, ask 1-3 questions before proceeding)

Quick Reference

Deliverables (What You Must Produce)

Your output MUST include:

A concrete directory layout (typically skills/<skill-name>/)
An actionable SKILL.md with decidable triggers, boundaries, and reproducible examples
Long-form docs moved to references/ with a references/index.md
A pre-delivery checklist (Quality Gate)

Built-in Tool (Mandatory): Skill Seekers (Linked)

This meta-skill exposes the tools/external/Skill_Seekers-development submodule through a relative symlink so you can generate a first-draft Skill from:

Documentation websites
GitHub repositories
PDFs

Bootstrap dependencies (once):

./skills/auto-skill/scripts/skill-seekers-bootstrap.sh

Run Skill Seekers (from linked source):

./skills/auto-skill/scripts/skill-seekers.sh -- --version
./skills/auto-skill/scripts/skill-seekers.sh -- scrape --config ./skills/auto-skill/scripts/Skill_Seekers-development/configs/react.json
./skills/auto-skill/scripts/skill-seekers.sh -- github --repo facebook/react --name react

What ships with it

24 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
