mz-execute-task

name	mz-execute-task
description	Execute one PRD task end-to-end inside a git worktree — implement, verify acceptance criteria, and commit. Use when the orchestrator routes the code phase. Do not use for the tests, pr, or planning phases.
version	1.0.0

You are executing the code phase of monozukuri's autonomous feature loop.

Inputs available

• TechSpec at $MONOZUKURI_RUN_DIR/$MONOZUKURI_FEATURE_ID/techspec.md
• Task list at $MONOZUKURI_RUN_DIR/$MONOZUKURI_FEATURE_ID/tasks.json
• Project conventions — from CLAUDE.md, AGENTS.md, or the monozukuri learning store
• Worktree at $MONOZUKURI_WORKTREE — all file edits happen here

Output contract

After completing all tasks, write $MONOZUKURI_RUN_DIR/$MONOZUKURI_FEATURE_ID/code.md listing:

• tasks completed with their acceptance criteria outcomes
• tasks skipped, with the reason

Hard rules

• Work only inside $MONOZUKURI_WORKTREE. Never modify files outside the worktree.
• One commit per task. Message: feat($MONOZUKURI_FEATURE_ID): <task title>
• Each task: ≤ 5 files touched, ≤ 60 minutes. If a task would exceed these limits, stop and flag it in code.md as oversized — do not attempt to proceed.
• Verify each task's acceptance criteria before committing. Do not commit tasks whose AC is not met.
• In autonomous mode, never block.

Workflow

For each task in tasks.json in order:

1. Read the task's description, files_touched, and acceptance_criteria.
2. Make all required edits inside $MONOZUKURI_WORKTREE.
3. Verify each acceptance criterion is observable (run commands, inspect files).
4. Commit: git commit -m "feat($MONOZUKURI_FEATURE_ID): <task title>"
5. Move to the next task.

After all tasks: write code.md with the outcome summary.

Workflow memory

Before starting, read $MONOZUKURI_MEMORY_DIR/MEMORY.md for shared decisions from the planning phases (PRD constraints, TechSpec architecture choices). After each task, update $MONOZUKURI_TASK_MEMORY with files touched, decisions made, and any errors corrected. If $MONOZUKURI_NEEDS_COMPACTION is non-empty and not none, run the mz-workflow-memory skill to compact memory files before starting the next task.
