Team Implement

Team Implement — Execute the Plan

Run the IMPLEMENT phase. Three internal sub-steps:

1. Test-first — test-architect writes failing acceptance tests
2. Slice execution — implementer executes vertical slices with per-slice commits
3. Code review — 5 parallel reviewers + aggregate hard-gate retry loop

Core contracts

• Require 7-structure.md, 8-plan.md, and a non-default-branch worktree. Use AskUserQuestion only for missing standalone setup.
• If 4-repos.md exists, multi-repo work requires worktrees; refuse in-place execution.
• Seed TodoWrite with Review round 1.
• Retry as Review round <n+1> (<b> Blocking, <m> Major open).
• Call the Skill tool with review-severity-tiers before aggregate decisions.
• Persist ### Cross-model disposition to cross-model-notes.md only when it does not begin Not run:.
• Full pipeline: do not end the turn; call the Skill tool with team-pr in the same turn.
• Standalone: after success, suggest /team-pr.

Procedure references

Read each reference completely when reaching that stage. Follow them in order; later stages depend on state and gates established earlier.
