Create a plan for a new feature or bug fix

Runtime Tools

When this skill needs user questions, todo/progress tracking, subagents, or another skill, use the active runtime equivalents in RUNTIME_TOOLS.md.

Follow the active shared and project instruction files. ETHOS.md is a human reference, not an additional mandatory runtime source.

Introduction

Use the current date from the active environment when dating plans. Treat dated examples as illustrative.

Transform feature descriptions, bug reports, or improvement ideas into:

1. spec.md - Human-readable plan with rationale, context, and design decisions
2. prd.json - Machine-executable story breakdown for systematic implementation
