Planning Workflow — The Foundation of Agentic Development

Core Philosophy: "Planning tokens are a lot fewer and cheaper than implementation tokens."

The models are far smarter when reasoning about a detailed plan that fits within their context window. This is the key insight behind spending 80%+ of time on planning.

Why Planning Matters

Before burning tokens with a big agent swarm:

• Measure twice, cut once — becomes "Check your plan N times, implement once"
• A very big, complex markdown plan is still shorter than a few substantive code files
• Front-loading human input in planning enables removing yourself from implementation
• The code will be written ridiculously quickly when you start enough agents with a solid plan
