Instructions for maintaining a Claude Code plugin marketplace, including its marketplace file, plugin folders, validation commands, and repository conventions.

In plain words

Why use it?
They provide a consistent structure for adding plugins and checking that the marketplace and its documentation are valid.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions Claude Code.

This is cblecker/claude-plugins's own configuration. It tells Claude Code how to work on claude-plugins 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 claude-plugins 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.

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

claude-plugins 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 25d 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.

Each plugin directory contains .claude-plugin/plugin.json and its own components (skills, hooks, agents, MCP configs). Plugins are at the repository root in a flat structure.

Commands

Command Purpose
claude plugin validate . Validate marketplace
claude plugin validate ./<plugin-name> Validate specific plugin
npx markdownlint-cli2 --config ${CLAUDE_PROJECT_DIR}/.markdownlint-cli2.jsonc "**/*.md" Lint markdown files
uvx skillsaw --strict Lint plugin

Adding a Plugin

  1. Create plugin directory at repository root using /plugin-dev:create-plugin

  2. Add entry to .claude-plugin/marketplace.json:

    {"name": "plugin-name", "source": "./plugin-name", "strict": true}
    
  3. Update README.md Available Plugins table

  4. Validate: claude plugin validate . and claude plugin validate ./<plugin-name>

Conventions

  • Use kebab-case for all names
  • Use ${CLAUDE_PLUGIN_ROOT} for portable paths in hooks/MCP configs
  • When editing plugin files (other than README.md or CLAUDE.md), bump the version in that plugin's .claude-plugin/plugin.json following semver:
    • patch: bug fixes, typo corrections, minor wording changes
    • minor: new skills, commands, hooks, agents, or backward-compatible behavior changes
    • major: breaking changes (renamed/removed skills, changed hook behavior, restructured plugin)
  • Only bump once per PR branch. Before bumping, check git diff main -- <plugin>/.claude-plugin/plugin.json to see if the version was already bumped. Skip if it was, unless the accumulated changes now warrant a higher semver level (e.g., patch already bumped but a new skill was added — upgrade to minor)
  • Use plugin-dev skills: /plugin-dev:create-plugin, /plugin-dev:skill-reviewer, /plugin-dev:plugin-validator
  • .skillsaw.yaml pins version to the skillsaw release the lint workflows run. Rules newer than that version are silently skipped, so when Dependabot bumps the stbenjam/skillsaw actions, bump version to match and re-run uvx skillsaw --strict. Deliberate !`command` preflight lines in skills must be added verbatim to the security-dynamic-context allowlist
  • CodeRabbit auto-review is disabled (reviews.auto_review.enabled: false in .coderabbit.yaml). Reviews are rate-limited, so request one manually with an @coderabbitai review comment only when the branch is ready — not after every push
  • When addressing automated review feedback on a PR (Copilot, CodeRabbit): wait until every reviewer has finished reviewing the current head, then push fixes for all findings as a single commit — one push per review round, not one per reviewer

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.
