Agents no longer commit task files (tasks/*.md) to their feature branches.
This eliminates the highest-frequency merge conflict category (parallel
agents committing metadata to the same file set). The coordinator updates
task status on main after merging source code changes.
Implementation specialist changes:
- Removed 'Update Task' workflow step (status/summary updates)
- Completion summary now included in worktree notify message
- Simplified Safe Exit (no task file commit step)
- Added 'do not commit task files' instruction to commit step
Coordinator changes:
- Added Task File Handling section with coordinator ownership model
- Updated spawn prompt template to include task file convention
- Added post-merge task status update step
