Plan a project

One plan file, in the template below, at docs/plan/PLAN.md unless the decider names another path. When the project has code, a repository AGENTS.md carries the rules that bind. Nothing else: no index, no brief, no mapping document unless asked.

The gate

Writing the plan and starting the work are different turns. Save the plan, summarise it, list the open questions, ask the decider to approve or amend, and end the turn. Planning tasks and writing code start only after approval arrives in a later turn.
