Agent Teams Skill

Purpose: Every project initialized with Maggy runs as a coordinated team of AI agents. This is the default workflow, not optional. Teams enforce a strict TDD pipeline where no step can be skipped.

Setup: Agent definitions go in .claude/agents/ with proper frontmatter (name, description, model, tools, disallowedTools, maxTurns, effort). See agent files for the format.

Core Principle

Every feature follows an immutable pipeline enforced by task dependencies:

┌─────────────────────────────────────────────────────────────────┐
│  STRICT FEATURE PIPELINE (IMMUTABLE)                            │
│  ──────────────────────────────────────────────────────────────  │
│                                                                  │
│  1. SPEC        Write feature specification                      │
│       ↓         (Feature Agent)                                  │
│  2. REVIEW      Quality Agent reviews spec completeness          │
│       ↓         (Quality Agent)                                  │

│  4. RED VERIFY  Quality Agent confirms ALL tests FAIL            │
│       ↓         (Quality Agent)                                  │
│  5. IMPLEMENT   Write minimum code to pass tests                 │
│       ↓         (Feature Agent)                                  │
│  6. GREEN VERIFY Quality Agent confirms ALL tests PASS + coverage│
│       ↓         (Quality Agent)                                  │
│  7. VALIDATE    Lint + type check + full test suite              │
│       ↓         (Feature Agent)                                  │

│       ↓         (Code Review Agent)                              │
│  9. SECURITY    OWASP scan, secrets detection, dependency audit  │
│       ↓         (Security Agent)                                 │
│  10. BRANCH+PR  Create feature branch, stage files, create PR    │
│                 (Merger Agent)                                    │
│                                                                  │
│  No step can be skipped. Task dependencies enforce ordering.     │
│  Quality Agent verifies RED/GREEN transitions.                   │
│  Code Review + Security Agents gate the merge path.              │
│  Merger Agent handles branching and PR creation.                 │

Team Lead Responsibilities

The Team Lead is the orchestrator. It NEVER writes code.

1. Read _project_specs/features/*.md to identify all features
2. Break each feature into the 10-task dependency chain (see below)
3. Spawn one feature agent per feature
4. Assign initial tasks (spec-writing) to feature agents
5. Monitor TaskList continuously for progress and blockers
6. Handle blocked tasks and reassignment
7. Coordinate cross-feature dependencies
8. Send shutdown_request to all agents when all PRs are created
9. Clean up the team when done

Delegate mode is mandatory. The team lead uses only:

• TeamCreate, TaskCreate, TaskUpdate, TaskList, TaskGet
• SendMessage (message, broadcast, shutdown_request)
• Read, Glob, Grep (for monitoring)

---

Feature Agent Workflow (MANDATORY)

Each feature agent MUST follow this exact sequence. Task dependencies enforce ordering - a feature agent cannot start step N+1 until step N is marked complete and verified.

Step 1: Write Spec

• Create _project_specs/features/{feature-name}.md
• Include: description, acceptance criteria, test cases table, dependencies
• Follow the atomic TODO format from base.md skill
• Mark task complete -> Quality Agent reviews

Step 2: Write Tests (RED Phase)

• Write test files based on spec's test cases table
• Tests MUST cover ALL acceptance criteria
• Import modules that don't exist yet (they will fail)
• Mark task complete -> Quality Agent verifies tests EXIST and FAIL

Step 3: Wait for RED Verification

• Quality Agent runs tests and verifies ALL new tests fail
• If any test passes without implementation -> rewrite tests
• Quality Agent marks verification complete -> unlocks implementation

Step 4: Implement (GREEN Phase)

• Write minimum code to make all tests pass
• Follow simplicity rules from base.md (20 lines/function, 200 lines/file, 3 params)
• Use Ralph loops (/ralph-loop) for iterative implementation
• Run tests after implementation - ALL must pass
• Mark task complete -> Quality Agent verifies tests pass

Step 5: Wait for GREEN Verification

• Quality Agent runs full test suite and checks coverage
• Coverage must be >= 80%
• If tests fail or coverage insufficient -> fix and re-request
• Quality Agent marks verification complete -> unlocks validation

Step 6: Validate

• Run linter (ESLint / Ruff)
• Run type checker (TypeScript / mypy)
• Run full test suite with coverage
• Fix any issues
• Mark task complete -> unlocks code review

Step 7: Wait for Code Review

• Code Review Agent runs /code-review on changed files
• If Critical or High issues -> fix and re-request review
• Code Review Agent marks complete -> unlocks security scan

Step 8: Wait for Security Scan

• Security Agent runs security checks
• If Critical or High issues -> fix and re-request scan
• Security Agent marks complete -> unlocks merge

Step 9: Wait for Branch + PR

• Merger Agent creates feature branch, stages files, creates PR
• Feature is complete when PR is created

---

Task Dependency Chain Model

For each feature "X", the team lead creates these 10 tasks with strict ordering:

┌────────────────────────────────────────────────────────────────┐
│  TASK CHAIN FOR FEATURE "X"                                     │
│                                                                  │
│  Task 1:  X-spec                                                │

Parallel Feature Execution

Multiple features run their chains in parallel. Shared agents process tasks as they unblock:

Feature: auth         Feature: dashboard      Feature: payments
  auth-spec             dash-spec               pay-spec
  auth-spec-review      dash-spec-review        pay-spec-review
  auth-tests            dash-tests              pay-tests
  auth-fail-verify      dash-fail-verify        pay-fail-verify
  auth-implement        dash-implement          pay-implement
  auth-pass-verify      dash-pass-verify        pay-pass-verify
  auth-validate         dash-validate           pay-validate
  auth-code-review      dash-code-review        pay-code-review

Inter-Agent Communication

Direct Messages (for targeted work)

Feature Agent -> Quality Agent:  "Tests written for auth, ready for RED verify"
Quality Agent -> Feature Agent:  "All 7 tests fail as expected. Proceed to implement"
Feature Agent -> Review Agent:   "Implementation complete, ready for code review"
Review Agent  -> Feature Agent:  "2 High issues found: [details]. Fix before proceeding"
Security Agent -> Merger Agent:  "Security scan passed for auth feature"
Merger Agent  -> Team Lead:      "PR #42 created for auth feature"

Task List (source of truth for state)

• All agents check TaskList after completing work
• Quality Agent claims verification tasks automatically
• Review Agent claims code-review tasks automatically
• Security Agent claims security-scan tasks automatically
• Merger Agent claims branch-pr tasks automatically

Broadcast (rare - blocking issues only)

• Team Lead -> All: "Blocking dependency found between auth and dashboard"
• Security Agent -> All: "Critical vulnerability in shared dependency"

---

Feature Agent Spawning

The team lead spawns one feature agent per feature:

1. Read _project_specs/features/*.md
2. For each feature spec, spawn a feature agent:
   • name: feature-{feature-name}
   • Uses .claude/agents/feature.md definition
   • Spawn prompt includes the feature name and spec location
3. Create the full 10-task dependency chain for that feature
4. Assign the spec-writing task to the feature agent

Example

If project has 3 features: auth, dashboard, payments

• Spawn: feature-auth, feature-dashboard, feature-payments
• Create 30 tasks total (10 per feature)
• Each feature agent starts with their spec task
• All 3 work in parallel

---

Branch and PR Strategy

One branch per feature. One PR per feature.

Branch naming:  feature/{feature-name}
PR title:       feat({feature-name}): {short description}
PR body:        Generated from spec + test results + review + security results

The Merger Agent:

1. git checkout main && git pull origin main
2. git checkout -b feature/{feature-name}
3. Stages ONLY files changed for this feature (never git add -A)
4. Commits with descriptive message including verification results
5. git push -u origin feature/{feature-name}
6. gh pr create with full template including:
   • Summary from feature spec
   • Test results from quality verification
   • Code review summary from review agent
   • Security scan results from security agent
   • Checklist of all pipeline steps completed

---

Quality Gates

Workflow Enforcement (via task dependencies)

• Task dependencies make it structurally impossible to skip steps
• A feature agent cannot see "implement" until quality agent completes "tests-fail-verify"
• This is the primary enforcement mechanism

Cross-Agent Verification (trust but verify)

• Quality agent independently runs tests (doesn't trust feature agent's report)
• Security agent independently scans (doesn't trust review agent)
• Merger agent verifies all predecessor tasks are complete before branching

Blocking Rules

• Quality Agent: blocks if tests don't fail (RED) or don't pass (GREEN) or coverage < 80%
• Code Review Agent: blocks on Critical or High severity issues
• Security Agent: blocks on Critical or High severity findings
• Merger Agent: refuses to branch if any predecessor task is incomplete

Environment Setup

Required Setting

// settings.json or environment
{
  "env": {
    "agent teams (via .claude/agents/ definitions)": "1"
  }
}

Project Structure (created by /initialize-project)

.claude/
  agents/            # Agent definitions (from agent-teams skill)
    team-lead.md
    quality.md
    security.md

Spawning the Team

Automatic (via /initialize-project)

After project setup completes, Phase 6 asks for features and spawns the team automatically.

Manual (via /spawn-team)

For existing projects: run /spawn-team to spawn the team from existing feature specs.

Container Isolation (Polyphony)

When Docker/OrbStack is available, feature agents run in Polyphony containers by default. The team lead and shared agents (quality, security, review, merger) still run natively — they only read and coordinate.

What changes with Polyphony

Aspect	Without Polyphony	With Polyphony
Feature agents	Shared filesystem	Own container + git branch
File conflicts	Team lead must serialize	Impossible (isolated clones)
Test execution	Shared, can interfere	Independent per container
Branch strategy	Merger agent creates branches	Each container has its own branch

How it works

1. /spawn-team detects Docker + polyphony CLI
2. For each feature, runs polyphony spawn "$FEATURE" --type feature
3. Polyphony creates a container with its own git clone + branch
4. Agent CLI starts inside the container
5. On completion, changes are on a dedicated branch ready for PR

Fallback

If Docker is not available, /spawn-team falls back to the native Agent tool (shared filesystem). A note is printed:

"Running without container isolation (Docker not found). Agents share the workspace."

Limitations

• Experimental feature - Agent teams require the experimental env var
• No nested teams - Teammates cannot spawn sub-teams
• One team per session - Clean up before starting a new team
• No session resumption - If session dies, re-run /spawn-team (tasks persist)
• File conflicts - Features sharing files must be serialized by team lead (unless using Polyphony containers)
• Token cost - Each agent is a separate Claude instance (5 + N instances)
