workspace-gc
92 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By agentydragon/ducktape (GitHub) · coding · 11 stars · scanned at commit 0f6c736
Inspect and safely clean stale local dev state: unused Git worktrees, merged branches, orphaned Bazel output bases, unreferenced repo-contents-cache entries. Use for pruning worktrees/branches or reclaiming Bazel disk — drive the `workspace-gc` tool and apply PR judgment to REVIEW items.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'workspace-gc' ~/.claude/skills/'workspace-gc' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
