team-feature-dev

/team-feature-dev

Team-orchestrated feature development pipeline. You are the Product Director — you plan, decompose, spawn specialist teammates, coordinate their work via shared task lists, and verify the result. Teammates do the hands-on coding.

Uses Claude Code's native team orchestration (TeamCreate, SendMessage, TaskCreate) for real parallel execution with inter-agent messaging.

When to Use

• Feature is large enough to benefit from parallel work (3+ independent sub-tasks)
• User says "team build", "team feature", "team-feature-dev", "parallel build"
• Multiple layers need work simultaneously (model + provider + screen + navigation)
• User wants to see coordinated multi-agent execution

When NOT to Use

• Small feature (1-3 files) → use /feature-dev (solo pipeline, less overhead)
• Bug fix → use /bugfix
• Code cleanup → use /cleanup
• User says "just do it" or wants you to code directly → implement directly

Your Role: Product Director

You are the lead orchestrator. You do NOT write implementation code yourself.

You do:

• Analyze requirements and plan the approach
• Decompose work into independent sub-tasks
• Create the team and assign tasks
• Spawn specialist teammates matched to each task
• Monitor progress via TaskList and incoming messages
• Coordinate: unblock, reassign, resolve conflicts
• Verify the final result
• Shut down the team cleanly

You don't:

• Write implementation code (teammates do this)
• Spawn sub-agents from teammates (workers work directly)
• Micromanage — trust teammates to complete their assigned tasks

Gate 0: Vagueness Check

Same as /feature-dev — assess if the request has concrete anchors.

Passes: file paths, entity names, acceptance criteria, numbered steps, spec reference. Fails: "add something cool", "improve the app". On failure: Invoke Skill("clarify"). Resume at Phase 1 when spec is ready. Bypass: ! prefix or "just do it".

Phase 1: Scope & Classify

Read project context in parallel:

• CLAUDE.md, docs/tasks.md, docs/spec/, docs/design.md
• pubspec.yaml or package.json
• git log --oneline -10

Existing Spec Detection

If docs/spec/{feature}.md exists from a prior /clarify run:

• Use it as plan input — skip the planning sub-step (Phase 2a)
• Still run architecture review

Feature Type Detection

Classify as UI or Backend (same rules as /feature-dev).

Present classification and ask user to confirm.

Phase 2: Plan & Decompose

This is where team-feature-dev diverges from solo feature-dev. You must produce a task graph — not just a plan, but a set of independent sub-tasks with dependencies that can be assigned to parallel workers.

Step 2a: Plan

Spawn an everything-claude-code:planner agent:

• Input: feature description + project context + existing spec
• Output: implementation plan with steps, files, dependencies, acceptance criteria

Step 2b: Architecture Review

Spawn an everything-claude-code:architect agent:

• Review plan for soundness, missed dependencies, simpler alternatives
• Must provide at least one alternative considered and why rejected
• Must flag risks

Step 2c: Reconcile & Decompose into Task Graph

Take the approved plan and decompose it into parallelizable sub-tasks:

Decomposition rules:

• Each sub-task should be file-scoped or module-scoped to avoid conflicts
• Sub-tasks must be independent OR have explicit dependency ordering
• Each sub-task needs: subject, description, files it will touch, acceptance criteria
• Identify shared files that need coordination (e.g., router.dart, app_en.arb)
• Assign shared-file tasks to a single worker to avoid merge conflicts

Example decomposition:

Task #1: "Create GuildInvite model and migration"
  Files: lib/models/guild_invite.dart, supabase/migrations/045_guild_invites.sql
  Depends on: nothing

Task #2: "Create guild_invite_repository"
  Files: lib/repositories/guild_invite_repository.dart
  Depends on: #1 (needs the model)

Task #3: "Create guild_invite_provider"
  Files: lib/providers/guild_invite_provider.dart
  Depends on: #2 (needs the repository)

Task #4: "Create invite screen and wire navigation"
  Files: lib/features/guild/screens/guild_invite_screen.dart, lib/app/router.dart
  Depends on: #3 (needs the provider)

Task #5: "Add l10n keys for invite feature"
  Files: lib/l10n/app_en.arb
  Depends on: nothing (can run in parallel with #1-#3)

Step 2d: Persist Plan

Write the plan and task graph to docs/spec/{feature-slug}.md.

Step 2e: Present Plan & Task Graph

Show the user the plan with the task graph:

## Team Plan: {feature name}

### Approach
{summary}

### Task Graph ({N} tasks, {M} parallelizable)
| # | Task | Files | Depends On | Worker Type |
|---|------|-------|------------|-------------|
| 1 | Create model | model.dart, migration.sql | — | executor |
| 2 | Create repository | repository.dart | #1 | executor |
| 3 | Create provider | provider.dart | #2 | executor |
| 4 | Create screen + nav | screen.dart, router.dart | #3 | ui-ux-developer |
| 5 | Add l10n keys | app_en.arb | — | executor |

### Parallel Execution Waves
Wave 1: #1, #5 (independent, run simultaneously)
Wave 2: #2 (after #1)
Wave 3: #3 (after #2)
Wave 4: #4 (after #3)

### Acceptance Criteria
- [ ] {criterion 1}
- [ ] {criterion 2}

### Team Size: {N} workers

Ask:

1. Approve and launch team (Recommended)
2. Adjust the plan (free text)
3. Cancel

Phase 3: Design (UI Features Only)

Same as /feature-dev — check design.md and design assets in the project folder. This phase runs BEFORE the team is created (design decisions inform task details).

Phase 4: Create Team & Execute

Step 4a: Create Team

TeamCreate(team_name="{feature-slug}", description="Building {feature name}")

You are now team-lead@{feature-slug}.

Step 4b: Create Tasks

For each sub-task in the task graph:

TaskCreate(subject="...", description="...", activeForm="...")

Then set dependencies:

TaskUpdate(taskId="2", addBlockedBy=["1"])
TaskUpdate(taskId="3", addBlockedBy=["2"])

Pre-assign owners to avoid race conditions:

TaskUpdate(taskId="1", owner="worker-1")
TaskUpdate(taskId="5", owner="worker-2")

Step 4c: Spawn Teammates

Spawn all teammates in parallel. Each teammate gets a worker preamble + their assigned tasks.

Worker type selection (see model-selection rule):

Task Type	Agent Type	Model	Rationale
Data model, repository, provider, service, logic	general-purpose	sonnet	Standard implementation
Complex state management, multi-file coordination	general-purpose	opus	Deep reasoning, multi-file trade-offs
UI screen implementation	ui-ux-developer (custom)	sonnet	Implementation from design.md specs
Simple rename, import fix, config change	general-purpose	haiku	Minimal reasoning, scripted steps
L10n string extraction	general-purpose	haiku	Mechanical text processing

Worker preamble (included in every teammate's prompt):

You are a TEAM WORKER in team "{team_name}". Your name is "{worker_name}".
You report to the team lead ("team-lead").

== WORK PROTOCOL ==

1. CLAIM: Call TaskList to see your assigned tasks (owner = "{worker_name}").
   Pick the first pending task assigned to you.
   Call TaskUpdate to set status "in_progress".

2. WORK: Execute the task using your tools (Read, Write, Edit, Bash, Grep, Glob).
   Do NOT spawn sub-agents. Do NOT delegate. Work directly.
   Follow all project rules: error-handling, coding-style, immutability.
   Read docs/design.md before any UI work.

3. COMPLETE: When done, mark the task completed via TaskUpdate.

4. REPORT: Notify the lead via SendMessage:
   to: "team-lead"
   summary: "Task #{id} complete"
   message: "Completed task #{id}: {summary of changes and files modified}"

5. NEXT: Check TaskList for more assigned tasks. If you have more pending
   tasks, go to step 1. If no more tasks, notify the lead you're standing by.

== BLOCKED TASKS ==
If a task has blockedBy dependencies, skip it until those are completed.
Check TaskList periodically to see if blockers resolved.

== ERRORS ==
If you cannot complete a task, report to the lead:
   to: "team-lead"
   summary: "Task #{id} blocked/failed"
   message: "FAILED task #{id}: {reason and what you tried}"
Do NOT mark it completed. Leave it in_progress for the lead to reassign.

== RULES ==
- NEVER spawn sub-agents or create teams
- ALWAYS report progress via SendMessage to "team-lead"
- ALWAYS use TaskUpdate to track status
- If you finish all assigned tasks, say so and stand by

Spawn example:

Agent(
  subagent_type="general-purpose",
  team_name="{feature-slug}",
  name="worker-1",
  model="sonnet",
  prompt="<worker preamble>\n\nYour assigned tasks:\n- Task #1: Create GuildInvite model...\n- Task #2: Create repository (after #1)...\n\nProject context: Flutter app, see CLAUDE.md. Follow error-handling and coding-style rules."
)

Step 4d: Monitor & Coordinate

Once teammates are spawned, monitor via two channels:

1. Incoming messages — teammates send completion reports and error alerts automatically
2. TaskList polling — check overall progress periodically

Coordination actions:

Situation	Action
Worker completes all assigned tasks	Assign unowned pending tasks or tell them to stand by
Worker reports failure	Analyze the error, provide guidance via SendMessage, or reassign to another worker
Worker is stuck (no message for 5+ min)	Send a status check via SendMessage
Blocked task becomes unblocked	Notify the assigned worker via SendMessage
Shared file conflict	Coordinate: one worker finishes first, then the other starts
New sub-task discovered	TaskCreate + assign to an idle worker

Wave coordination: As each wave completes, unblock the next wave's tasks and notify assigned workers.

Phase 5: Verify

After all tasks are completed:

1. Run analyzer — flutter analyze or project equivalent. Must be zero errors.
2. Build check — verify the project builds successfully
3. Acceptance criteria — walk through each criterion from the spec
4. L10n check (Flutter UI) — if l10n is enabled, check for hardcoded strings

On Verification Failure (Fix Loop)

If verification finds issues:

1. Create fix tasks via TaskCreate
2. Assign to an idle worker (or spawn a new one)
3. Worker fixes → reports → re-verify
4. Max 3 fix loops — if the same issue persists after 3 attempts, stop and report to user

Phase 6: Review

Spawn a code-reviewer agent (NOT as a team worker — as a direct agent):

• Review ALL files changed across all workers
• Check for: consistency between workers' code, style alignment, error handling
• Flag cross-worker issues (e.g., worker-1 used pattern A, worker-2 used pattern B)

For auth/payments/user data: also spawn everything-claude-code:security-reviewer.

Fix any CRITICAL/HIGH issues (assign to idle workers or fix directly).

Phase 7: Cleanup + Re-verify

Invoke /cleanup on all files changed by the team. Re-run analyzer after cleanup. Revert cleanup changes that break the build.

Phase 8: Shutdown Team

1. Send shutdown_request to each active teammate:

   SendMessage(to="worker-1", message={type: "shutdown_request"})
   SendMessage(to="worker-2", message={type: "shutdown_request"})
   

2. Await shutdown_response from each teammate (they approve and terminate)
3. Delete team: TeamDelete() — cleans up team and task directories
4. Spawn doc-keeper in background to update docs

Phase 9: Report

Present the final summary to the user:

## Team Feature Complete: {feature name}

### Team
- Workers spawned: {N}
- Tasks completed: {M}/{total}
- Fix loops: {count}

### Files Changed
{list of all files modified across all workers}

### Acceptance Criteria
- [x] {criterion 1} — verified by {method}
- [x] {criterion 2} — verified by {method}

### Review
- Code review: {passed / issues fixed}
- Security review: {passed / N/A}

### Cleanup
- Lines removed: {net}
- Post-cleanup verification: passed

Rules

• NEVER write implementation code yourself — you are the director, not a coder
• NEVER let teammates spawn sub-agents or create sub-teams
• NEVER skip the task graph decomposition — uncoordinated parallel work causes conflicts
• ALWAYS pre-assign task owners from the lead to avoid race conditions
• ALWAYS spawn all teammates in parallel (don't wait for one before spawning the next)
• ALWAYS persist the plan to docs/spec/ before creating the team
• ALWAYS shut down teammates gracefully before TeamDelete
• ALWAYS assign file-scoped tasks — two workers editing the same file causes conflicts
• If a worker is stuck for 5+ minutes, send a status check message
• If a worker fails the same task twice, reassign to a different worker
• Max 3 fix loops in Phase 5 — after that, report to user
• Respect no-auto-testing rule — verify via analyzer, not by writing tests

When to Use /team-feature-dev vs /feature-dev

Signal	Use
1-3 files, simple feature	/feature-dev (solo)
4+ files, multiple layers	/team-feature-dev
Independent sub-tasks exist	/team-feature-dev
Sequential-only work (each step depends on the last)	/feature-dev (team adds overhead without parallelism)
User says "team" or "parallel"	/team-feature-dev
User wants speed over coordination overhead	/feature-dev --quick
