Optimize any AI skill. Prove it with benchmarks.
Benchmark prompts, skills, and instructions across Claude, ChatGPT, Cursor, Gemini, and Windsurf. Ship the improved version with a measurable report card.
Works everywhere
One optimized skill, packaged for every major AI surface.
What are AI skills?
AI models are general-purpose by default. Skills make them specialists. Better skills mean better output — and we can prove it.
Skills are instructions for AI
A skill is a system prompt, custom instruction, or workflow definition that tells an AI model how to approach a specific task. Think of it as the difference between a generic assistant and a trained specialist.
Anyone can create them
Developers, teams, and creators write skills for everything from code review to debugging to strategic planning. They work across Claude, ChatGPT, Cursor, Gemini, and Windsurf.
Optimization makes them measurably better
We run your skill through blind evaluation with binary pass/fail criteria and 3 independent AI judges. If the optimized version wins, you get it. If it doesn't, you get a refund.
Proof, not promises
Every optimized skill ships with a report card showing before/after scores, win rate, judge breakdown, and SHA-256 verification. You see exactly what improved and by how much.
See the difference.

The Karpathy Loop works — but your LLM will lie to you
Auto-optimizing prompts is real. But if you don't control the evaluation, the LLM learns to game the judge instead of actually improving. Without proper fitness function design, you get reward hacking — not improvement.
Naive AutoResearch
- AI learns to game the judge instead of actually improving
- Scaled scoring (1-10) compounds probability noise across iterations
- Single-judge evaluation creates systematic bias
- Output gets longer and more verbose — looks "better" to LLM judges but isn't
Presient's Approach
- Binary pass/fail criteria — no noisy scaled scores to game
- 3 independent blind judges (different AI models) vote on every test case
- Randomized A/B ordering prevents position bias
- Proper fitness function design — the hard part that makes optimization actually work
Our proof: the Writing Plans failure
We ran our own writing-plans skill through optimization with poorly designed fitness tests. The result? Score dropped from 78% to 75%. The AI "optimized" for length and verbosity instead of actual planning quality. The optimized version was larger, slower, and worse.
You can run the loop yourself. Designing the right fitness function is the hard part.
We've run hundreds of evaluations through this pipeline. The methodology matters more than the automation — that's what we sell.
Every optimization comes with proof.
