Team-orchestrated feature development pipeline. You are the **Product Director** —
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.
/feature-dev (solo pipeline, less overhead)/bugfix/cleanupYou are the lead orchestrator. You do NOT write implementation code yourself.
You do:
You don't:
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".
Read project context in parallel:
CLAUDE.md, docs/tasks.md, docs/spec/, docs/design.mdpubspec.yaml or package.jsongit log --oneline -10If docs/spec/{feature}.md exists from a prior /clarify run:
Classify as UI or Backend (same rules as /feature-dev).
Present classification and ask user to confirm.
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.
Spawn an everything-claude-code:planner agent:
Spawn an everything-claude-code:architect agent:
Take the approved plan and decompose it into parallelizable sub-tasks:
Decomposition rules:
router.dart, app_en.arb)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)
Write the plan and task graph to docs/spec/{feature-slug}.md.
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:
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).
TeamCreate(team_name="{feature-slug}", description="Building {feature name}")
You are now team-lead@{feature-slug}.
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")
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."
)
Once teammates are spawned, monitor via two channels:
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.
After all tasks are completed:
flutter analyze or project equivalent. Must be zero errors.If verification finds issues:
Spawn a code-reviewer agent (NOT as a team worker — as a direct agent):
For auth/payments/user data: also spawn everything-claude-code:security-reviewer.
Fix any CRITICAL/HIGH issues (assign to idle workers or fix directly).
Invoke /cleanup on all files changed by the team.
Re-run analyzer after cleanup. Revert cleanup changes that break the build.
SendMessage(to="worker-1", message={type: "shutdown_request"})
SendMessage(to="worker-2", message={type: "shutdown_request"})
TeamDelete() — cleans up team and task directoriesPresent 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

Task: {{ARGUMENTS}}
npx claudepluginhub nextc/nextc-claude --plugin nextc-coreLaunches agent team for feature implementation using parallel coders, specialized reviewers, and tech lead with structured pipeline. For multi-file changes or frontend/backend features.
Use when a task benefits from multiple Claude instances collaborating with peer-to-peer messaging - parallel research, multi-module features, cross-layer changes, or competing hypothesis debugging. Not for simple independent tasks (use parallel-execution) or sequential tasks (use delegated-execution).
