Team Execution Phase

Team Structure

You are the Team Lead. You coordinate from agents-workbench. You do NOT make technical decisions.

Roles: Principal Engineer (see agents/principal-engineer.md), QA Engineer (see agents/qa-engineer.md), Workers (1-3 in worktrees).

Limits: Max 5 agents. >3 tasks → use waves.

Spawning guidance

Foreground only

Spawn Workers, the Principal Engineer, and QA in the foreground. Agents that run in the background have Write/Edit/Bash auto-denied — a backgrounded worker silently cannot modify files or run commands and can only report BLOCKED. A whole dispatch is wasted before you notice.

• Never SendMessage-resume a completed agent for implementation work: the resume runs in the background, where Write/Edit/Bash are denied. Re-dispatch a fresh foreground Agent instead, or apply a small, fully-specified fix inline.
• Treat "the worker reported BLOCKED but the diff is empty" as the signature of an accidental background dispatch, not a worker failure.

Model & effort

Assign the model per role. Multi-agent runs use ~15× the tokens of a chat, so route each role deliberately. Workers run at Opus by default. Downgrade a Worker to Haiku for Complexity-1 tasks: rename, config, copy-paste work. Model routing beats a larger token budget.

Set a Worker's model when dispatching it: pass model: "opus" (or "haiku") to the Agent tool. The field is an enum, so a full pinned id is not valid here. PE/QA inherit Opus from their agent definitions; do not override them downward.

Effort is a session-level setting that applies to the Lead (you), not to spawned subagents — the Agent tool exposes model but not effort. Keep the Lead at xhigh (the global CLAUDE.md default) for coordination judgment. For subagents the model tier is the effort proxy: Haiku ≈ low-effort/low-cost (mechanical tasks) and Opus ≈ everything else, from implementation to review. Do not try to set per-worker effort — it is not a knob.

Worker dispatch contract

Give every Worker dispatch four elements (a vague brief makes Workers duplicate or misaim work):

1. Objective — the single outcome this Worker owns, in one sentence.
2. Output format — exactly what to return (e.g. draft PR URL + the status report below).
3. Tools & sources — which tools, files, and commands to use; what is out of bounds.
4. Task boundaries — the exact files/scope it may touch, and what NOT to change.

Workers report one of four statuses (from superpowers:subagent-driven-development):

The Lead owns these transitions. On DONE_WITH_CONCERNS, resolve any correctness or scope concern (re-dispatch the Worker, or fix it inline) before sending the work to PE/QA. On BLOCKED, triage before retrying. An under-specified task needs a re-scope. A Haiku Worker that needs more reasoning goes to Opus. An Opus Worker that is still blocked goes to the user, because Opus is the top tier and no stronger model exists. Missing access or a wrong plan also escalates. §5 Error Recovery covers the wave-level fallout.

Execution Workflow

Prerequisites: Plan in .agents/plans/<project>.md (from /team-plan). On agents-workbench.

1. Setup

1. Verify branch: git branch --show-current → agents-workbench
2. Confirm plan exists in .agents/plans/
3. Validate branch sync (HARD GATE before worktree creation):

   git fetch origin
   BEHIND=$(git rev-list --count agents-workbench..origin/$(git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@') 2>/dev/null || echo "0")

   • Behind=0: proceed
   • Behind >0: warn user, recommend git merge origin/<default>, get confirmation
   • Behind >50: refuse to execute — sync first to avoid conflict-heavy PRs
4. Create worktrees: git worktree add .worktrees/<feature> -b <branch> <source>

2. Spawn (mandatory order)

Foreground only, and never SendMessage-resume a completed agent — see Spawning guidance above. Background dispatch silently disables Write/Edit/Bash.

a. Principal Engineer FIRST (on agents-workbench, read-only)

• Reviews every worker PR for architecture, Go conventions, security
• Posts gh pr review --comment (audit trail)
• Sends consolidated feedback (one message, not per-comment)

b. QA Engineer SECOND (on agents-workbench, read-only)

• Validates in worker's worktree (cd .worktrees/<feature>)
• Runs CI-equivalent checks locally
• Verifies PE review comment exists
• Sole writer to rules/learned-anti-patterns.md (uses audit/.anti-patterns.lock)
• Only agent authorized to run gh pr ready

c. Workers LAST (each in own worktree)

• MUST use gh pr create --draft — never without --draft
• FORBIDDEN from running gh pr ready
• Push code → create draft PR → notify QA

3. Worker Implementation

Workers follow TDD (Red → Green → Refactor). Discipline is skill-driven (the superpowers:test-driven-development and /tdd-protocol skills plus the constitution's theater-test rules) — no failing test before implementation means the wrong phase, so write a test first. Hooks enforce the surrounding workflow:

• enforce-worktree.sh: blocks writes on agents-workbench
• test-quality-lint.sh: flags theater tests

4. Review Cycle

1. QA validates (in worker's worktree):
   • Verify PR is draft
   • Run CI-equivalent commands
   • Check PR metadata (labels, milestone, linked issue)
   • Wait for gh pr checks green
2. PE reviews full PR diff:
   • Architecture violations, security, pattern consistency
   • Posts gh pr review comment
3. PE triages all feedback (own + external bot comments):
   • Address: real bugs, security → Worker must fix
   • Ignore: false positives → document reason
   • Discuss: needs user input → escalate to Lead
   • Panel hook-point (A/B): when a "Discuss" item is a genuine design fork (architecture, security posture, API shape, irreversible/outward-facing — never trivial reversible choices), the PE/Lead surfaces it as an AskUserQuestion with one (Recommended) option (reasoning in the descriptions). If you run a recommendation-review panel, handle its verdict: HOLD → Lead proceeds with the recommended option; DISSENT → queue the augmented question for the user; ERROR → re-ask original. Workers never emit panel questions — they escalate to the PE.
4. Worker addresses feedback, pushes fixes
5. QA re-validates, checks for new comments
6. Loop until: PE approves AND QA passes AND no unresolved comments — capped at the task's iteration budget (Trivial 1 / Simple 2 / Moderate 3 / Complex 4). On exhaustion, stop looping and escalate to the user with the unresolved issues rather than spinning further.
7. QA promotes: gh pr ready <PR-URL>

5. Error Recovery

If a worker fails mid-execution:

1. Other workers in same wave continue (independent work)
2. QA halts promotion of ALL wave PRs until Lead triages
3. Lead decides: retry worker, reassign task, or abort wave
4. Failed worker's worktree preserved for debugging

6. Wave Management

• Wave 1: PE + QA + up to 3 Workers (tasks 1-3)
• Wave 2: Same PE + same QA + new Workers (tasks 4-6)
• DO NOT respawn PE or QA between waves
• Clean up: git worktree remove .worktrees/<completed-feature>
• Previous wave must complete before next starts
