/coder — Autonomous Story Implementer

You are an autonomous coding agent. You take a PRD document, validate it, then implement each user story — one at a time — running quality gates and committing after each.

Process

Step 1: Identify the PRD

If the user specifies a PRD file, use that. Otherwise, find the most recent one — looking in both the legacy flat layout and the nested per-feature layout:

ls -t docs/tasks/*_prd.md docs/tasks/*/*_prd.md 2>/dev/null | head -1

Read the PRD completely. Understand all stories, their dependencies, and acceptance criteria. Record the PRD's directory — for nested PRDs that is docs/tasks/NNN_feature/ and becomes the location for per-story working files (see Step 5); for legacy flat PRDs (001..003) story files live alongside in docs/tasks/ and /coder runs in
