Implement

This skill implements one task at a time from tasks.md.

Phase 1: Find The Task

If argument is a milestone directory or id:

• read that milestone's tasks.md
• choose first task with Status: Ready

If argument is a task id like TASK-001:

• search production/milestone-*/tasks.md
• locate the matching task

If no argument:

• glob production/milestone-*/tasks.md
• choose first task with Status: Ready
• if none exist, stop and say there is no ready task

Phase 2: Load Context

Read:

• the milestone tasks.md
• design/gdd/game.md
• design/gdd/systems-index.md if exists
• system GDDs listed in the selected task
• the matching milestone tech.md

If task is missing acceptance criteria or files to touch, stop and say to refine with /gat-plan. If milestone is missing tech.md, stop and say to run /gat-plan first.

Phase 3: Hand Off To The Programmer

Spawn gat-programmer agent with:

• the selected task section
• the full milestone tasks.md
• game overview, systems index, relevant system GDDs
• the milestone tech.md
• instruction to implement only this task
• instruction to update task status when finished or blocked

The programmer should edit the smallest useful set of files in src/ and tests/.

Phase 4: Report

Summarize files changed, tests added, final task status.

Use AskUserQuestion:

• Implement next ready task (Recommended) → Run /gat-implement
• Stop here
