Improve and optimize prompts for Claude using Anthropic's official best practices and the 5-Element Persona Framework. Use when asked to improve, refine, optimize, or review a prompt. Also triggers on requests to make prompts clearer, more effective, better structured, or to get better/more realistic outputs from Claude. Covers Claude 4.x-specific techniques, persona engineering, constraint-based prompting, and structured outputs.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'prompt-improver' ] || [ -L ~/.agents/skills/'prompt-improver' ]; then echo 'A skill folder named prompt-improver already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/zocomputer/skills' "$d" && git -C "$d" checkout --quiet 'a86c4b112e108e0d1938f5e61ee3a1de59e37f1d' -- 'Community/prompt-improver' && mkdir -p ~/.agents/skills && cp -R "$d"/'Community/prompt-improver' ~/.agents/skills/'prompt-improver' && rm -rf "$d"; fi

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/'prompt-improver' ~/.claude/skills/'prompt-improver' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
