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

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 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.

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.md should be concise + actionable.
  • REFERENCES.md should 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)

  1. Identify the most specific skill folder.
  2. Update SKILL.md first.
  3. Add/refresh links in REFERENCES.md.
  4. 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
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.
