plugin-marketplace
A local marketplace of Claude Code plugins — self-contained packages that extend Claude with hooks, skills, agents, and MCP servers.
Plugins
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
Routes tasks to the appropriate Claude model tier (Haiku / Sonnet / Opus) based on task complexity, reducing cost without sacrificing quality.
Skills: /dispatch:route, /dispatch:haiku, /dispatch:sonnet, /dispatch:opus
Interactive wizard for managing project-level settings.local.json permissions. Detects project type, suggests safe permission patterns, and reduces manual approval friction.
Command: /permissions
Features: Smart project-type detection, categorized permission safety levels, proactive suggestions when starting new projects.
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.
MCP server and hook-driven automation for structured problem-solving workflows. Decomposes problems, specifies requirements, generates solutions, validates output, and resumes context across sessions.
Agents: decomposer, specifier, generator, validator, calibrator
Hooks: SessionStart (resume context), PostToolUse (validate stage), PreCompact/PostCompact (save/restore state)
Requires: Python ≥ 3.12, uv
Automated wiki maintenance for this plugin marketplace. Ingests plugin source files, lints wiki docs, and keeps the knowledge base in sync.
Agents: ingest-agent, lint-agent, remediate-agent, obsidian-agent
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:
