description	Agent Teams orchestration patterns for multi-agent SAFe workflows. Use when spawning agent teams, coordinating teammates, enforcing quality gates via task dependencies, or orchestrating the 11-agent SAFe pipeline. Covers team creation, messaging, shared task lists, and SAFe gate enforcement. Do NOT use for single-agent or simple subagent workflows.

Team Coordination Skill

TEMPLATE: This skill uses {{PLACEHOLDER}} tokens. Replace with your project values before use.

Purpose

Orchestrate multi-agent teams for SAFe workflows. This skill provides patterns for spawning teams, assigning work by role, enforcing quality gates via task dependencies, and managing the full delivery pipeline.

Prerequisites

Agent Teams may be experimental depending on provider. Enable as required:

// Provider-specific settings
{
  "env": {
    "AGENT_TEAMS_ENABLED": "1"
  }
}

When This Skill Applies

• Orchestrating work across multiple agent roles (FE, BE, QAS, etc.)
• Spawning a team for a Feature or Epic-level deliverable
• Coordinating parallel implementation with quality gate enforcement
• Running competing hypothesis debugging with multiple agents
• Performing parallel code review across security, performance, and test coverage

Agent Teams vs Subagents vs Background Agents

Approach	Communication	Coordination	Best For
Agent Teams	DMs, broadcasts	Shared TaskList with dependencies	Complex multi-role SAFe workflows
Subagents	Report back only	Main agent manages	Focused tasks, results only
Background Agents	None	None	Fire-and-forget parallel work

Use Agent Teams when: teammates need to share findings, challenge each other, and coordinate via SAFe gates. Use Subagents when: you need quick, focused workers that report back. Use Background Agents when: tasks are independent and do not need coordination.

SAFe Team Patterns

Pattern 1: TDM as Team Lead

The TDM (Technical Delivery Manager) is the natural team lead in the 11-agent model:

Create an agent team for ASP-XXX implementation.

Team lead (TDM) responsibilities:
- Spawn teammates by role (BE, FE, QAS, etc.)
- Create tasks with SAFe gate dependencies
- Monitor progress and steer teammates
- Synthesize results and escalate blockers

Spawn these teammates:
- BE Developer: Implement API endpoints per spec
- FE Developer: Implement UI components per spec
- QAS: Validate acceptance criteria after implementation

Pattern 2: Task Dependencies for Quality Gates

Use task dependencies to enforce the SAFe pipeline:

Task structure for ASP-XXX:

1. "Implement API endpoint" (owner: be-developer)
2. "Implement UI components" (owner: fe-developer)
3. "QAS validation" (owner: qas, blockedBy: [1, 2])
4. "Create PR" (owner: rte, blockedBy: [3])
5. "Stage 1 review" (owner: system-architect, blockedBy: [4])

This enforces: Implementation -> QAS -> RTE -> Architect Review

Pattern 3: Spawning Teammates by Role

Map harness agent roles to teammate configurations:

Spawn teammates with role-specific prompts:

BE Developer teammate:
- Load: api-patterns, rls-patterns skills
- Task: Implement endpoints per spec at specs/ASP-XXX-spec.md
- Constraint: All DB operations must use RLS context helpers

FE Developer teammate:
- Load: frontend-patterns skill
- Task: Implement UI per spec
- Constraint: Follow API patterns in patterns_library/api/

QAS teammate:
- Load: testing-patterns skill
- Task: Execute testing strategy from spec
- Constraint: Must verify all acceptance criteria before approving

Pattern 4: Parallel Code Review

Create an agent team to review PR #XXX. Spawn three reviewers:
- Security reviewer: Focus on RLS enforcement, input validation, auth checks
- Architecture reviewer: Focus on pattern compliance, separation of concerns
- Test reviewer: Focus on test coverage, edge cases, acceptance criteria

Have them each review independently, then share and challenge findings.

Pattern 5: Competing Hypothesis Debugging

Users report [issue description]. Spawn 3-4 teammates to investigate:
- Teammate 1: Investigate [hypothesis A]
- Teammate 2: Investigate [hypothesis B]
- Teammate 3: Investigate [hypothesis C]

Have them talk to each other to challenge and disprove theories.
Update findings as consensus emerges.

Communication Patterns

Direct Messages (Most Common)

Send a message to the BE developer:
"The API endpoint needs to handle pagination. Check patterns_library/api/
for the standard pagination pattern before implementing."

Broadcast (Use Sparingly -- Expensive)

Broadcast to all teammates:
"STOP: Architecture decision changed. The auth middleware now uses
{{AUTH_PROVIDER}} session tokens instead of JWT. Check the updated
spec before continuing."

Only broadcast for:

• Critical blocking issues
• Architecture changes affecting everyone
• Stop-the-line announcements

Shutdown Coordination

When all tasks are complete:
1. Send shutdown request to each teammate
2. Wait for approval from each
3. Clean up team resources

Quality Gate Hooks

TeammateIdle Hook

Validates teammates completed their work before going idle. Configure hook to return exit code 2 to send feedback and keep the teammate working.

TaskCompleted Hook

Validates task output meets criteria before allowing completion. Configure hook to return exit code 2 to prevent completion and send feedback.

Team Sizing Guidelines

Work Scope	Recommended Size	Tasks per Teammate
Single Story	2-3 teammates	3-4 tasks each
Feature (multi-story)	3-5 teammates	5-6 tasks each
Epic (parallel features)	5-8 teammates	5-6 tasks each

Rules of thumb:

• Start with fewer teammates; scale up if needed
• Each teammate should own different files (avoid conflicts)
• 5-6 tasks per teammate keeps everyone productive
• More than 8 teammates rarely helps (coordination overhead)

Known Limitations

• Experimental: May require feature flag to enable
• No session resumption: Resuming may not restore in-process teammates
• One team per session: Clean up before starting a new team
• No nested teams: Teammates cannot spawn their own teams
• Permissions inherit: All teammates start with lead's permission mode
• Token cost: Significantly higher than single session
