pdd

We built PDD (Prompt-Driven Development) to shift the source of truth from code to prompts. What it is - CLI that treats prompts as first-class artifacts. You write a prompt; PDD generates the code, a minimal usage example, and tests. It can run a verify step that compares program output against the prompt and iterates until it passes. What’s different - Prompts stay in sync with code. If you edit code by hand, `update` back-propagates changes into the prompt so the prompt remains authoritative. - End-to-end “sync” flow: auto-deps → generate → example → crash/verify → test → fix, with cost/attempt budgets. - Traceability: map a code line back to the prompt section that produced it.
