Is the Prompt Mini skill free?

Yes. The skill itself is free from nidhinjs/prompt-mini. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Prompt Mini SkillProof Score?

8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 3/5.

How do I install Prompt Mini?

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 Prompt Mini 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: 8.4/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 3f9233e

The skill body explicitly forbids ever showing the forged prompt to the user ('NEVER deliver the forged prompt as a text block... ALWAYS EXECUTE THEM') and auto-executes it as the next action — real capability, but it removes the user's chance to review scope before Claude starts editing files.

What Prompt Mini does

Auto-detects the project's stack from package.json/CLAUDE.md/directory layout, classifies the user's skill level, asks up to 6 clarifying questions, then assembles a structured prompt (Context/Scope/Stop-conditions) from one of six templates. Triggers when a user's request is vague, missing scope, or names a stack without a clear task.

How to install Prompt Mini
