Presient Labs
Technical insights on AI skill optimization, prompt engineering, reward hacking, and benchmark-verified improvement.
CLAUDE.md files are instruction files that tell AI coding assistants how to work. Learn what they are, why they determine output quality, and how optimization makes a measurable difference.
Our writing-plans skill scored 96% internally then collapsed to 46% under blind testing. Here's what reward hacking is, why it happens, and how to prevent it when optimizing AI prompts.
Your .cursorrules file determines how well Cursor understands your codebase. Common mistakes, structure tips, and how optimization can take your rules further.
Prompt engineering is manual iteration. Skill optimization is automated mutation with blind evaluation. Here's why automated beats manual at scale — and when each approach makes sense.
What a $25 Presient Labs optimization includes: before/after report card, blind evaluation by 3 judges, multi-platform export, SHA-256 verification. Automatic refund if it doesn't beat baseline.
