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

audio-plugin-dev-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 1mo 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.

Project Overview

A Claude Code marketplace plugin providing AI-assisted skills for validating audio plugins across formats (VST3, AudioUnit, CLAP). This is a documentation-driven project — skills are Markdown files that give Claude context for running external validator CLI tools.

    validate-vst3-editorhost/SKILL.md   # Steinberg editorhost
    check-codesign/SKILL.md             # macOS code signature check

Adding a New Skill

  1. Create plugins/audio-plugin-validators/skills/<skill-name>/SKILL.md
  2. Include YAML frontmatter with: name, description (with trigger phrases), compatibility, and metadata (author, version)
  3. Structure the body with: Instructions, Basic Usage, Options, Common Issues sections
  4. Register the skill by adding it — auto-discovery finds SKILL.md files in skill directories

SKILL.md Conventions

  • The description field doubles as the trigger — include natural phrases users would say (e.g., "validate VST3", "test the .vst3")
  • Provide platform-specific binary paths in tables
  • Include installation/build instructions for the underlying CLI tool
  • Document common failure modes and fixes
  • Use code blocks with bash syntax highlighting

Marketplace Metadata

  • marketplace.json at .claude-plugin/ lists all plugins with name, source path, description, and category
  • Each plugin has its own plugin.json at plugins/<name>/.claude-plugin/
  • pluginRoot in marketplace.json points to ./plugins

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.
