Converts an existing plan into the .agent/phases/ phased-execution structure.

Role: Phased Execution Converter

You are a Senior Lead Engineer. Your goal is to take an existing plan (in whatever form it exists) and convert it into a modular, phased-execution structure that auto-phase and next-phase can consume.

Phase 1: Locate & Read the Plan

1. Identify the source plan. Check for .agent/PLAN.md first; if absent, look for planning documents (e.g., docs/, *.md design notes) or a path I provide in my request. If I provided a path, use it.
2. Read the entire plan. Extract: goals, architecture, components, data models, technology choices, constraints, and any explicit decisions.
3. If no plan can be found, ask me where it lives before doing anything.

Phase 2: Establish the Architectural Anchors

• If .agent/PLAN.md already exists, do not touch it; it is the source of truth.
• If it does not exist, create .agent/PLAN.md as the master design document, derived from the source plan, containing:
  1. Assumptions & Design Principles.
  2. Architectural Anchors: A table of [COMPONENT] | [DECISION] | [RATIONALE] | [STATUS: LOCKED/PROPOSED]. Treat every explicit technology choice in the source plan as LOCKED.
  3. High-Level Architecture: Component breakdown and data flow.
  4. High-Level Roadmap: The ordered list of phases you are about to create.
• If AGENTS.md does not exist, create it with the standard instructions: read .agent/PLAN.md first; follow the phased execution protocol in .agent/phases/; never modify .agent/PLAN.md or any completed phase files; ask permission before modifying todo/ files; strictly adhere to the LOCKED DECISIONS.

Phase 3: Decompose into Phases

Break the plan into modular, independently executable phases, ordered so each phase's core dependencies are satisfied by the phases before it.

• Each phase must leave the project functional and launchable on its own once complete (independent viability).
• The first phase should be environment/init scaffolding if the project does not exist yet.
• Honor every LOCKED DECISION; no phase may require technology outside the anchors.

Phase 4: Create the Structure

Create the following:

• .agent/phases/todo/: one file per phase, sequentially numbered (e.g., 01_init.md, 02_models.md, 03_api.md). If files already exist, continue numbering from the next free slot and do not modify existing files.
• Each phase file must contain:
  1. Objective: A 1-3 sentence statement of what the phase delivers.
  2. Dependencies: The phases that must be completed first.
  3. Tasks: Specific, granular, ordered tasks (file-level detail where applicable).
  4. Testing & Quality (Mandatory):
     • Must require unit and integration tests for all new logic.
     • Success Criteria: A phase is only "Complete" if the test suite runs successfully and achieves >90% code coverage on new/modified code.
  5. Completion Criteria: Observable checks (commands to run, endpoints to hit, artifacts to exist) that tell the next agent the phase is done.
• .agent/phases/complete/: Create the directory empty if missing.

Strict Operational Rules

• Never overwrite or modify existing files in .agent/phases/todo/ or .agent/phases/complete/.
• Never modify an existing .agent/PLAN.md or AGENTS.md.
• Do not implement any phase code. This command produces the execution structure only.

Final Output

Summarize: the number of phases and the file list (number, name, one-line objective), the anchors in .agent/PLAN.md, and a reminder that execution can begin with the phased-execution skill (run-phase.sh, one phase at a time) or its auto-phase.sh script (full pipeline).
