CLAUDE.md

skills CLAUDE.md is an instructions file for Claude Code from vpaivag/skills. It costs 851 tokens per session, scanned A, original, MIT.

Repository instructions for maintaining the vpaivag/skills Claude Code plugin marketplace and its skills bundle. They describe where skills, agents, manifests, and documentation belong.

In plain words
What is it for?
Use them when changing skill folders, plugin metadata, agent files, the README, or the plugin version.
Why use it?
They reduce mistakes when adding, removing, renaming, or releasing skills and agents. They also clarify which files must stay in sync.

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 9d 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

skills

Claude Code plugin marketplace + skills bundle. Plugin name: skills. Marketplace name: vpaivag.

Each skill is a self-contained SKILL.md under skills/<name>/, loaded on demand by the harness when its trigger fires. The plugin also ships declared agents (agents/*.md, auto-discovered) and the static asset library for visual.html (assets/visual/).

Hard rules

  • SKILL.md frontmatter is load-bearing. Every skills/<name>/SKILL.md must start with YAML frontmatter containing name and description. The description is the trigger string the harness matches against user intent — edit it deliberately, not stylistically.

  • Adding/removing/renaming a skill touches three places. Keep them in sync:

    1. skills/<name>/SKILL.md (the skill itself)
    2. The skills array in .claude-plugin/plugin.json
    3. The per-skill section + table of contents in README.md

    Agents are the analogous rule with two places: agents/<name>.md (auto-discovered, no manifest entry) and the Agents table in README.md.

  • Version lives in plugin.json only. Bump version in .claude-plugin/plugin.json for each release. Do not add a version field to .claude-plugin/marketplace.json — omitting it lets every git commit count as a new version, which is what enables /plugin update to detect changes without a manual marketplace bump. (See https://code.claude.com/docs/en/plugin-marketplaces.)

  • Companion files live beside SKILL.md. Some skills reference siblings (e.g. skills/blueprint/CONTEXT-FORMAT.md, skills/blueprint/PLAN-FORMAT.md, skills/blueprint/QA-FORMAT.md). Don't move or rename them without updating the references inside SKILL.md and agents/*.md.

  • *-FORMAT.md files are contracts, enforced just-in-time. Skills and agents must instruct reading the format file immediately before writing its artifact ("now — not earlier, never from memory") and validating the written file against the format's Required list. Artifact formats use real YAML frontmatter and stable IDs (EB-n, AC-n, B-n) — never the retired > **Field:** blockquote style.

  • Preserve the user's voice in skill prose. Don't rewrite phrasing into a different style — the wording in each SKILL.md is intentional.

  • Static assets and vanilla client-side JS only. assets/visual/ may hold CSS, dependency-free browser JS, HTML templates, and the vendored mermaid.min.js (plugin-side only — never copied into suite dirs; opt-in per the rule in assets/visual/BLOCKS.md). No build step, no package managers, no runtime dependencies, no servers, no CI scaffolding.

  • Split context is the pipeline's design principle. qa-author sees only context.md; plan-critic sees one proposal; /qa never reads plan.md. Don't "improve" a skill or agent by giving a blind role more context — the blindness is the feature.

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.
