PDD (Prompt-Driven Development) inverts the traditional development model: instead of writing code directly, you write prompt files that describe what you want, then let AI generate and maintain the code for you. Prompts are versioned, composable, and regenerable — your code becomes a disposable artifact.

What PDD does

PDD provides a complete workflow from a natural-language prompt to production-ready, tested code:
1

Write a prompt file

Describe what you want in a .prompt file using natural language. Prompts are modular and composable — one prompt per module.
2

Run pdd sync

The sync command runs the full cycle automatically: resolves dependencies, generates code, creates runnable examples, verifies correctness, generates tests, fixes bugs, and back-propagates learnings to your prompt.
3

Iterate with prompts, not code

When requirements change, update the prompt and regenerate. PDD’s fingerprint-based change detection only regenerates what needs updating.
4

Implement GitHub issues automatically

Use pdd change <issue-url> or pdd bug <issue-url> to let PDD implement or fix GitHub issues end-to-end using an agentic multi-step workflow.

Choose your workflow

Web Interface

Launch pdd connect for a visual browser-based UI — the easiest way to get started

Issue-Driven CLI

Point PDD at a GitHub issue and let it implement the feature or fix automatically

Prompt Workflow

Write prompt files and use pdd sync for full manual control over the generation cycle
