Fine to try.

Use when writing or improving prompts for a language model. Covers instruction structure, examples, reasoning elicitation, output formatting, and systematically diagnosing why a prompt fails. Trigger on "improve this prompt", "the model ignores my instructions", "prompt works sometimes and fails randomly". Do not use for guaranteeing schema-valid JSON — see the structured-output skill; for measuring prompt quality, see the llm-evaluation skill.

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-engineering' ] || [ -L ~/.agents/skills/'prompt-engineering' ]; then echo 'A skill folder named prompt-engineering already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nimadorostkar/Claude-Skills-collection' "$d" && git -C "$d" checkout --quiet '1691932edc17063d712a85d02bcc7a1cd3791057' -- 'skills/ai/prompt-engineering' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/ai/prompt-engineering' ~/.agents/skills/'prompt-engineering' && 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-engineering' ~/.claude/skills/'prompt-engineering' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
