whetstone

plugin-marketplace

A local marketplace of Claude Code plugins — self-contained packages that extend Claude with hooks, skills, agents, and MCP servers.

Plugins

whetstone v1.4.1

Meta-plugin that injects project state into every session and synthesizes session transcripts into a persistent knowledge base. The backbone for self-improving Claude Code setups.

Skills: /whetstone:route, /whetstone:think, /whetstone:verify, /whetstone:compress, /whetstone:synthesizer, /whetstone:improve, /whetstone:setup

Auto-behaviors:

• Routes before any task requiring >2 tool calls
• Thinks before implementation when confidence is low
• Verifies before reporting done
• Compresses context when turns exceed 10

toon

Transparently converts structured data in prompts to TOON format for token-efficient LLM processing, then converts responses back to JSON for display. Saves 30–60% tokens on structured data.

Extraction methods: LLM (Claude API), Markdown tables, key-value regex — with graceful fallback.

Installation

Each plugin is self-contained. Install by pointing Claude Code at the plugin directory:

# Load a single plugin
claude --plugin-dir /path/to/plugin-marketplace/whetstone

# Or copy to your Claude plugins directory
cp -r whetstone ~/.claude/plugins/

Then enable in ~/.claude/settings.json:

{
  "enabledPlugins": {
    "whetstone": true
  }
}

Plugin Structure

Each plugin follows the Claude Code plugin spec:
