Is the Clean Cache skill free?

Yes. The skill itself is free from addxai/enterprise-harness-engineering. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Clean Cache SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Clean Cache?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Clean Cache with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Actually ran the bundled scan-and-delete bash commands against a throwaway workspace with a fake node_modules, android build/, and .dart_tool/: L1 cleanup wiped only the build artifacts and left package-lock.json, src/, and node_modules exactly where the skill's own 'Red Lines' table says they must stay — the safety claims are real, not just documented.

What Clean Cache does

Batch-scans a workspace of Flutter/Android/iOS/Node.js projects, sizes up build artifacts vs project dependencies vs global caches into three safety tiers (L1/L2/L3), and only auto-executes the safe L1 tier while requiring explicit confirmation for anything that would force a re-download. Triggers on 'clean cache', 'disk space low', 'free up space' and similar. Tested live against a throwaway multi-project workspace: it correctly sized .dart_tool/, android app/build, and node_modules, then L1 cleanup deleted only the build artifacts and left package-lock.json, node_modules, and source files untouched exactly as its red-lines table promises.

How to install Clean Cache

git clone https://github.com/addxai/enterprise-harness-engineering
cd enterprise-harness-engineering
mkdir -p ~/.claude/skills
cp -r skills/clean-cache ~/.claude/skills/clean-cache

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Clean Cache

/clean-cache Tiered, confirmation-gated cache cleanup for Flutter/Android/iOS/Node workspaces — verified not to touch lockfiles or source.

It also activates on plain-language prompts like these:

My disk space is low, scan and clean my Flutter and Node projects
Free up space across my workspace without touching any source files
Tier my build caches and only auto-delete the safe ones
