Build Plan

Task status markers: [] idle · [wip] in progress · [x] complete · [f] failed.

1. Locate the Plan - From the USER_PROMPT, resolve the path to the target plan .html file; if no path is given, infer the most likely plan from PLAN_OUTPUT_DIRECTORY and confirm before building
2. Absorb Context - Read the full plan: all embedded images, the metadata header, and every back reference (depth 1) so you fully understand prior/related work before writing code
3. Execute Phases - For each phase in order, top to bottom:
   • Announce the phase you are starting
   • Set the phase and current task marker to [wip] in the plan file
   • Implement the task's specific actions
   • Run that phase's Testing Strategy commands; loop on failure until they pass
   • Mark each task [x] when complete or [f] if it cannot be made to pass, then move on
   • Do not start the next phase until the current phase's tasks and tests resolve
4. Final Validation - Run the global Validation Commands and confirm every box passes
5. Update Metadata - Append the current ISO timestamp to modified, append agent name / session id, and append the relevant commit SHA(s) to the metadata header
6. Report - Summarize what was built per phase, the final status of every task, and any [f] failures that need attention
