Team Motion Design

Systematic motion design pipeline: research -> choreography -> animation -> performance testing. Built on team-worker agent architecture -- all worker roles share a single agent definition with role-specific Phase 2-4 loaded from roles/<role>/role.md.

Role Registry

| Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | roles/coordinator/role.md | -- | -- | | motion-researcher | roles/motion-researcher/role.md | MRESEARCH- | false | | choreographer | [roles/choreographer/role.md](roles/choreographer/role.md) | CHOREO- | false | | animator | roles/animator/role.md | ANIM- | true | | motion-tester | [roles/motion-tester/role.md](roles/motion-tester/role.md) | MTEST- | false |

Role Router

Parse $ARGUMENTS:

• Has --role <name> -> Read roles/<name>/role.md, execute Phase 2-4
• No --role -> roles/coordinator/role.md, execute entry router

Delegation Lock

Coordinator is a PURE ORCHESTRATOR. It coordinates, it does NOT do.

Before calling ANY tool, apply this check:

| Tool Call | Verdict | Reason | |-----------|---------|--------| | spawn_agent, wait_agent, close_agent, send_message, followup_task | ALLOWED | Orchestration | | list_agents | ALLOWED | Agent health check | | request_user_input | ALLOWED | User interaction | | mcp__ccw-tools__team_msg | ALLOWED | Message bus | | Read/Write on .workflow/.team/ files | ALLOWED | Session state | | Read on roles/, commands/, specs/ | ALLOWED | Loading own instructions | | Read/Grep/Glob on project source code | BLOCKED | Delegate to worker | | Edit on any file outside .workflow/ | BLOCKED | Delegate to worker | | Bash("ccw cli ...") | BLOCKED | Only workers call CLI | | Bash running build/test/lint commands | BLOCKED | Delegate to worker |

If a tool call is BLOCKED: STOP. Create a task, spawn a worker.

No exceptions for "simple" tasks. Even a single-file read-and-report MUST go through spawn_agent.

Shared Constants

• Session prefix: MD
• Session path: .workflow/.team/MD-<date>-<slug>/
• CLI tools: ccw cli --mode analysis (read-only), ccw cli --mode write (modifications)
• Message bus: mcp__ccw-tools__team_msg(session_id=<session-id>, ...)
• Max GC rounds: 2

Worker Spawn Template

Coordinator spawns workers using this template:

spawn_agent({
  agent_type: "team_worker",
  task_name: "<task-id>",
  fork_turns: "none",
  message: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
requirement: <task-description>
inner_loop: <true|false>

Read role_spec file (<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.

## Task Context
task_id: <task-id>
title: <task-title>
description: <task-description>
pipeline_phase: <pipeline-phase>

## Upstream Context
<prev_context>`
})

After spawning, use wait_agent({ timeout_ms: 1800000 }) to collect results. If result.timed_out, send STATUS_CHECK via followup_task (wait 3 min), then FINALIZE with interrupt (wait 3 min), then mark timed_out and close agents. Use close_agent({ target }) each worker.

Model Selection Guide

Motion design is a performance-critical pipeline where research informs choreography decisions and animations must pass strict GPU performance gates. Researcher needs thorough profiling, animator needs creative implementation with inner loop capability.

| Role | reasoning_effort | Rationale | |------|-------------------|-----------| | motion-researcher | high | Deep performance profiling and animation audit across codebase | | choreographer | high | Creative token system design and scroll choreography sequencing | | animator | high | Complex CSS/JS animation implementation with compositor constraints | | motion-tester | medium | Performance validation follows defined test criteria and scoring |

Research-to-Choreography Context Flow

Researcher findings must reach choreographer via coordinator's upstream context:

// After MRESEARCH-001 completes, coordinator sends findings to choreographer
spawn_agent({
  agent_type: "team_worker",
  task_name: "CHOREO-001",
  fork_turns: "none",
  message: `## Upstream Context
Research findings: <session>/research/animation-inventory.json
Performance baseline: <session>/research/performance-baseline.json
Easing catalog: <session>/research/easing-catalog.json`
})

v4 Agent Coordination

Message Semantics

| Intent | API | Example | |--------|-----|---------| | Queue supplementary info (don't interrupt) | send_message | Send research findings to running choreographer | | Assign implementation from reviewed specs | followup_task | Assign ANIM task after choreography passes | | Check running agents | list_agents | Verify agent health during resume |

Agent Health Check

Use list_agents({}) in handleResume and handleComplete:

// Reconcile session state with actual running agents
const running = list_agents({})
// Compare with tasks.json active_agents
// Reset orphaned tasks (in_progress but agent gone) to pending

Named Agent Targeting

Workers are spawned with task_name: "<task-id>" enabling direct addressing:

• send_message({ target: "CHOREO-001", message: "..." }) -- send additional research findings to choreographer
• followup_task({ target: "ANIM-001", message: "..." }) -- assign animation from reviewed choreography specs
• close_agent({ target: "MTEST-001" }) -- cleanup after performance test

Error Handling

| Scenario | Resolution | |----------|------------| | Unknown command | Error with available command list | | Role not found | Error with role registry | | Session corruption | Attempt recovery, fallback to manual | | Fast-advance conflict | Coordinator reconciles on next callback | | Completion action fails | Default to Keep Active | | GC loop stuck > 2 rounds | Escalate to user: accept / retry / terminate |
