The Problem

Why This Was Built

Managing installed agent skills across multiple assistants (.agents, .claude, .codex, .cursor) with Node-based tools is slow to start, requires heavy runtime dependencies, and lacks terminal-native batch weeding and MCP integration.

The Solution

The Architectural Answer

A high-speed, compiled Go binary and stdio MCP server that scans thousands of skill cards in half a second, safely consolidates duplicates, repairs broken shortcuts, and serves an embedded web desk with zero runtime requirements.

Frequently Asked Questions

Is Skill Cabinet Go a replacement for subsy/skill-cabinet?

No, it is a high-performance terminal companion and CLI/MCP counterpart to subsy's original Node reference implementation, designed for headless environments, automated scripting, and fast terminal workflows.

Does it require Node.js or external runtime dependencies?

No. It compiles to a single, static binary with the web UI fully embedded via go:embed.

What MCP tools does Skill Cabinet Go expose?

It provides get_cabinet_census, list_skills, get_skill, search_skills, and diagnose_cabinet for any MCP-compatible coding assistant.
