Turn vague asks into production-grade prompts — diagnose the failure mode, write a strict output contract, structure task/context/rules/examples, harden against 8 failure modes, and validate with a mini eval. Use when writing prompts, improving prompts, designing system prompts, or fixing an AI that ignores instructions.
My prompt keeps producing inconsistent output — diagnose the failure mode and rewrite it with a strict output contract
What you get
- SKILL.md with a 7-step engineering workflow (diagnose the failure mode, write an output contract, structure task/context/rules/examples, harden against failure modes, validate with a mini eval) + 4 reference docs (prompt anatomy, techniques toolbox, failure modes, testing playbook) + a demo prompt-lab HTML page
Good fit
- Anyone writing or improving prompts, designing system prompts or agent instructions, fixing an AI that ignores instructions, or reducing hallucinations in a specific task
Not for
- General writing advice, model selection, or API integration code — those are adjacent tasks, not prompt engineering
