MengTo/Skills is a collection of reusable instruction folders that teach coding agents workflows for interface design, games, frontend systems, automations, and agent loops. Designers and developers use the skills to turn references, prompts, and implementation habits into repeatable work. The catalogue contains the project’s skills and supporting instruction.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00333 | $0.00333 |
| Opus 5 | $0.00167 | $0.00167 |
| Sonnet 5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
Skills CLAUDE.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.

What it actually says
Claude Code — Repo Guide
Repo: @MengTo/Skills
This repo contains designer-focused AgentSkills for reusable agent workflows.
What to do here
- Add new skills (new folders under
agent-skills/) - Improve existing skills (
SKILL.md+REFERENCES.md) - Keep docs procedural: checklists, recipes, pitfalls, workflows
Folder contract
Each skill folder should look like:
agent-skills/<category>/<skill-name>/
SKILL.md # required (frontmatter + steps)
REFERENCES.md # optional (links only)
ARTICLE.md # optional (long-form)
assets/ # optional
scripts/ # optional
Conventions:
SKILL.mdshould be concise + actionable.REFERENCES.mdshould be links only (no big explanations).- Prefer copy/paste snippets and “when to use” triggers.
Style
- Write like Meng To: skimmable, practical, confident.
- Prefer constraints and defaults (durations, spacing, hierarchy).
- Avoid fluff.
Safety
- Don’t include secrets, API keys, tokens.
- Don’t paste private client info.
Suggested workflow (for Claude)
- Identify the most specific skill folder.
- Update
SKILL.mdfirst. - Add/refresh links in
REFERENCES.md. - Keep changes small and commit with a clear message.
Git
This folder is its own git repo. Work from:
cd /Users/mengto/clawd/@MengTo/Skills
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.

Skills CLAUDE.md is an instructions file published in the GitHub repository MengTo/Skills (5,814 stars, last pushed 8d ago), licensed MIT. It adds 333 tokens to every session, about $0.0017 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
