Is the Rocky skill free?

Yes. The skill itself is free from hpbyte/rocky. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Rocky SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Rocky?

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 Rocky 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.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 28b6cc2

Ran it live on a Docker 'no space left on device' question: skill output kept every command (docker system df, docker builder prune -a, docker system prune -a --volumes) in ~50 words vs. a ~140-word baseline, matching the repo's own before/after eval snapshot pattern almost exactly.

What Rocky does

Rewrites Claude's communication style into Rocky's translated-alien-engineer cadence: short declarative sentences, dropped articles, sparse check-prompts ('yes?'), while preserving code/commands/identifiers exactly. Triggers on explicit persona requests ('talk like Rocky', '/rocky') or requests for compact/direct phrasing without losing technical accuracy; a safety clause drops the voice for destructive or high-precision situations.

How to install Rocky

git clone https://github.com/hpbyte/rocky
mkdir -p ~/.claude/skills
cp -r rocky/skills/rocky ~/.claude/skills/rocky

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