About Skillful

Skillful is a local-first desktop app for building reusable AI skills and agents as real folders, then installing them into Claude Code, Codex, Cursor, Copilot, Gemini, Junie, and opencode. Skillful turns prompts, agents, screenshots, scripts, and notes into a filesystem library you can inspect and maintain. Prompts, screenshots, scripts, and supporting notes live next to the skill that uses them. Keep `SKILL.md` and `AGENT.md` workflows in one library, with filters and badges that make the difference clear without splitting your workspace.

About Toolbay Stack

60 free MIT skills for Claude Code. 146 engines, every one carrying its own test. Built to refuse the one thing agent tooling does worst: reporting success while doing nothing. Set it up once, then list what you have built by asking. Most agent tooling fails silently: a guard that allows everything when it is missing, a check that exits 0 having done nothing, a save that writes somewhere you will never look. This is built around refusing that one behaviour, and the refusals are measured rather than claimed, npm run backtest reproduces every number on this page.
