skills: Instructions file for Claude Code

CLAUDE.md

skills CLAUDE.md is an instructions file for Claude Code from OmarSaleh506/skills. It costs 843 tokens per session, scanned A, original, MIT.

A project instruction file describing how skills must be organized, listed, documented, and versioned in a Claude Code plugin marketplace.

In plain words
What is it for?
Use it when adding or changing skills in the repository, especially to check required files, listings, README entries, and version updates.
Why use it?
It gives contributors consistent rules so the marketplace entries, plugin files, and documentation do not drift apart.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions Claude Code.

This is OmarSaleh506/skills's own configuration. It tells Claude Code how to work on skills 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 skills configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo conventions

This is a public Claude Code plugin marketplace of portable agent skills. The whole collection ships as one plugin, omar-skills, in the skills marketplace.

Layout

.claude-plugin/
  marketplace.json   # the marketplace ("skills") + the omar-skills plugin entry
  plugin.json        # the omar-skills plugin manifest
skills/
  <skill-name>/
    SKILL.md         # required — the skill itself
    ...              # optional supporting scripts / reference docs

Rules for every shipped skill

  • It lives at skills/<name>/SKILL.md.
  • It is listed in the skills array of both .claude-plugin/plugin.json and .claude-plugin/marketplace.json (the two must always agree).
  • It has a row in README.md, with the skill name linked to its SKILL.md.
  • Bump version in plugin.json when you change what ships.

Invocation: model-invoked vs user-invoked

Every skill is one of two kinds, set in its SKILL.md frontmatter:

  • model-invoked (default) — reachable by the model or the user. Keep a rich, trigger-heavy description ("Use when the user wants…, asks for…") so it auto-fires. Use this for reusable discipline. ai-os-init is model-invoked.
  • user-invoked — reachable only when the human types its name. Set disable-model-invocation: true; keep the description short and human-facing. Use this for orchestration skills you want to fire deliberately.

A user-invoked skill may invoke model-invoked skills, never another user-invoked one.

Before adding anything

This repo is public — anything merged is visible forever (git history outlives deletion). Audit every skill before adding it; never commit one that contains secrets or machine-/work-specific details. Verify:

  • No secrets — no API keys, tokens, passwords, connection strings, or .env contents anywhere (including example snippets).
  • No personal/work identifiers — no internal hostnames, cluster/tenant names, account IDs, real emails, employer-specific service names, or private URLs.
  • No machine-specific absolute paths — use ${CLAUDE_PLUGIN_ROOT}, ~, or relative paths. Never hardcode /Users/<you>/....
  • Degrades gracefully — if a skill needs a tool beyond Python 3 / bash, it must skip rather than fail, and say so in its SKILL.md.
  • Generic, not internal — solves a problem anyone could have; infra- or employer-specific tooling belongs in a private repo, not here.

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.
