Instructions file for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions Claude Code.

This is verygoodplugins/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.

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

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 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Claude Code plugin marketplace repository. It hosts plugins that extend Claude Code functionality through commands, hooks, skills, and MCP server integrations.

Repository structure:

  • plugins/<name>/ - Individual plugin directories
  • .claude-plugin/marketplace.json - Marketplace registry listing all plugins

Currently contains the automem plugin (persistent memory via AutoMem MCP service). Other plugins (freescout, evernote, toggl, pirsch) are listed as "coming soon" placeholders.

Plugin Architecture

Each plugin follows this structure:

plugins/<name>/
├── .claude-plugin/plugin.json    # Plugin manifest (name, version, author, hooks/mcp refs)
├── .mcp.json                     # MCP server configuration (optional)
├── commands/*.md                 # Slash command definitions (YAML frontmatter + markdown)
├── hooks/hooks.json              # Event hooks (SessionStart, Stop, PostToolUse)
├── scripts/                      # Shell/Python scripts for hooks
└── skills/*/SKILL.md             # Skill definitions (YAML frontmatter + markdown)

Key Files

Manifest (plugin.json) - Required fields: name, version, description. Optional: hooks, mcpServers (paths to respective JSON files).

Commands - Markdown files with YAML frontmatter containing description. File name becomes command name (e.g., memory-store.md → /memory-store).

Hooks (hooks.json) - Maps events to handlers:

  • SessionStart - Runs on session begin
  • Stop - Runs when conversation ends
  • PostToolUse - Runs after specific tool execution (use matcher field)

Hooks can be type: "command" (shell scripts) or type: "prompt" (inject text).

Skills (SKILL.md) - YAML frontmatter with name, description, allowed-tools. Body contains detailed instructions.

AutoMem Plugin Details

The automem plugin provides persistent memory across sessions:

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.
