Command	Description

Skills

Skills are contextual and auto-loaded based on your conversation. When a request matches a skill's triggers, the agent loads and applies the relevant skill to provide accurate, up-to-date guidance.

Skill	Description
de-slop	Detect and remove "LLM smells" (AI-slop tells) from any text or document.
deepseek-consult	Consult DeepSeek for architectural review, code feedback, or a second opinion — with built-in calibration.

MCP servers

Some skills are backed by an MCP server in mcp-servers/. These ship Node code and need their dependencies installed before use.

Server	Backs skill	Tool
deepseek-consult	deepseek-consult	consult_deepseek

The repo's .mcp.json registers them for plugin installs via ${CLAUDE_PLUGIN_ROOT}. Dependencies (node_modules) are gitignored and resolved automatically:

• Plugin install — the SessionStart hook in hooks/hooks.json installs each server's runtime deps into the persistent ${CLAUDE_PLUGIN_DATA} and symlinks them into place. Nothing to run.
• Local dev — the servers are npm workspaces; one npm install at the repo root installs everything.

See each server's README for auth and registration details.
