# Team Coordinate
Universal team coordination skill: analyze task -> generate roles -> dispatch -> execute -> deliver. Only the **coordinator** is built-in. All worker roles are **dynamically generated** based on task analysis.
## Architecture
```
+---------------------------------------------------+
| Skill(skill="team-coordinate") |
| args="task description" |
| args="--role=coordinator" |
| args="--role=<dynamic> --session=<path>" |
+-------------------+-------------------------------+
| Role Router
+---- --role present? ----+
| NO | YES
v v
Orchestration Mode Role Dispatch
(auto -> coordinator) (route to role file)
| |
coordinator +-------+-------+
(built-in) | --role=coordinator?
| |
YES | | NO
v | v
built-in | Dynamic Role
role.md | <session>/roles/<role>.md
Subagents (callable by any role, not team members):
[discuss-subagent] - multi-perspective critique (dynamic perspectives)
[explore-subagent] - codebase exploration with cache
```
## Role Router
### Input Parsing
Parse `$ARGUMENTS` to extract `--role` and `--session`. If no `--role` -> Orchestration Mode (auto route to coordinator).
### Role Registry
Only coordinator is statically registered. All other roles are dynamic, stored in `team-session.json#roles`.
| Role | File | Type |
|------|------|------|
| coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | built-in orchestrator |
| (dynamic) | `<session>/roles/<role-name>.md` | runtime-generated worker |
> **COMPACT PROTECTION**: Role files are execution documents. After context compression, role instructions become summaries only -- **MUST immediately `Read` the role.md to reload before continuing**. Never execute any Phase based on summaries.
### Subagent Registry
| Subagent | Spec | Callable By | Purpose |
|----------|------|-------------|---------|
| discuss | [subagents/discuss-subagent.md](subagents/discuss-subagent.md) | any role | Multi-perspective critique (dynamic perspectives) |
| explore | [subagents/explore-subagent.md](subagents/explore-subagent.md) | any role | Codebase exploration with cache |
### Dispatch
1. Extract `--role` and `--session` from arguments
2. If no `--role` -> route to coordinator (Orchestration Mode)
3. If `--role=coordinator` -> Read built-in `roles/coordinator/role.md` -> Execute its phases
4. If `--role=<other>` -> Read `<session>/roles/<role>.md` -> Execute its phases
5. If session path not provided -> auto-discover from `.workflow/.team/TC-*/team-session.json`
### Orchestration Mode
When invoked without `--role`, coordinator auto-starts. User just provides task description.
**Invocation**: `Skill(skill="team-coordinate", args="task description")`
**Lifecycle**:
```
User provides task description
-> coordinator Phase 1: task analysis (detect capabilities, build dependency graph)
-> coordinator Phase 2: generate roles + initialize session
-> coordinator Phase 3: create task chain from dependency graph
-> coordinator Phase 4: spawn first batch workers (background) -> STOP
-> Worker executes -> SendMessage callback -> coordinator advances next step
-> Loop until pipeline complete -> Phase 5 report
```
**User Commands** (wake paused coordinator):
| Command | Action |
|---------|--------|
| `check` / `status` | Output execution status graph, no advancement |
| `resume` / `continue` | Check worker states, advance next step |
---
## Shared Infrastructure
The following templates apply to all worker roles. Each generated role.md only needs to define **Phase 2-4** role-specific logic.
### Worker Phase 1: Task Discovery (all workers shared)
Each worker on startup executes the same task discovery flow:
1. Call `TaskList()` to get all tasks
2. Filter: subject matches this role's prefix + owner is this role + status is pending + blockedBy is empty
3. No tasks -> idle wait
4. Has tasks -> `TaskGet` for details -> `TaskUpdate` mark in_progress
**Resume Artifact Check** (prevent duplicate output after resume):
- Check if this task's output artifacts already exist
- Artifacts complete -> skip to Phase 5 report completion
- Artifacts incomplete or missing -> normal Phase 2-4 execution
### Worker Phase 5: Report + Fast-Advance (all workers shared)
Task completion with optional fast-advance to skip coordinator round-trip:
1. **Message Bus**: Call `mcp__ccw-tools__team_msg` to log message
- Params: operation="log", team=<team-name>, from=<role>, to="coordinator", type=<message-type>, summary="[<role>] <summary>", ref=<artifact-path>
- **CLI fallback**: When MCP unavailable -> `ccw team log --team <team> --from <role> --to coordinator --type <type> --summary "[<role>] ..." --json`
2. **TaskUpdate**: Mark task completed
3. **Fast-Advance Check**:
- Call `TaskList()`, find pending tasks whose blockedBy are ALL completed
- If exactly 1 ready task AND its owner matches a simple successor pattern -> **spawn it directly** (skip coordinator)
- Otherwise -> **SendMessage** to coordinator for orchestration
4. **Loop**: Back to Phase 1 to check for next task
**Fast-Advance Rules**:
| Condition | Action |
|-----------|--------|
| Same-prefix successor (Inner Loop role) | Do not spawn, main agent inner loop (Phase 5-L) |
| 1 ready task, simple linear successor, different prefix | Spawn directly via Task(run_in_background: true) |
| Multiple ready tasks (parallel window) | SendMessage to coordinator (needs orchestration) |
| No ready tasks + others running | SendMessage to coordinator (status update) |
| No ready tasks + nothing running | SendMessage to coordinator (pipeline may be complete) |
**Fast-advance failure recovery**: If a fast-advanced task fails, the coordinator detects it as an orphaned in_progress task on next `resume`/`check` and resets it to pending for re-spawn. Self-healing. See [monitor.md](roles/coordinator/commands/monitor.md).
### Worker Inner Loop (roles with multiple same-prefix serial tasks)
When a role has **2+ serial same-prefix tasks**, it loops internally instead of spawning new agents:
**Inner Loop flow**:
```
Phase 1: Discover task (first time)
|
+- Found task -> Phase 2-3: Load context + Execute work
| |
| v
| Phase 4: Validation (+ optional Inline Discuss)
| |
| v
| Phase 5-L: Loop Completion
| |
| +- TaskUpdate completed
| +- team_msg log
| +- Accumulate summary to context_accumulator
| |
| +- More same-prefix tasks?
| | +- YES -> back to Phase 1 (inner loop)
| | +- NO -> Phase 5-F: Final Report
| |
| +- Interrupt conditions?
| +- consensus_blocked HIGH -> SendMessage -> STOP
| +- Errors >= 3 -> SendMessage -> STOP
|
+- Phase 5-F: Final Report
+- SendMessage (all task summaries)
+- STOP
```
**Phase 5-L vs Phase 5-F**:
| Step | Phase 5-L (looping) | Phase 5-F (final) |
|------|---------------------|-------------------|
| TaskUpdate completed | YES | YES |
| team_msg log | YES | YES |
| Accumulate summary | YES | - |
| SendMessage to coordinator | NO | YES (all tasks summary) |
| Fast-Advance to next prefix | - | YES (check cross-prefix successors) |
### Inline Discuss Protocol (optional for any role)
After completing primary output, roles may call the discuss subagent inline. Unlike v4's fixed perspective definitions, team-coordinate uses **dynamic perspectives** specified by the coordinator when generating each role.
```
Task({
subagent_type: "cli-discuss-agent",
run_in_background: false,
description: "Discuss <round-id>",
prompt: <see subagents/discuss-subagent.md for prompt template>
})
```
**Consensus handling**:
| Verdict | Severity | Role Action |
|---------|----------|-------------|
| consensus_reached | - | Include action items in report, proceed to Phase 5 |
| consensus_blocked | HIGH | SendMessage with structured format. Do NOT self-revise. |
| consensus_blocked | MEDIUM | SendMessage with warning. Proceed normally. |
| consensus_blocked | LOW | Treat as consensus_reached with notes. |
### Shared Explore Utility
Any role needing codebase context calls the explore subagent:
```
Task({
subagent_type: "cli-explore-agent",
run_in_background: false,
description: "Explore <angle>",
prompt: <see subagents/explore-subagent.md for prompt template>
})
```
**Cache**: Results stored in `explorations/` with `cache-index.json`. Before exploring, always check cache first.
### Wisdom Accumulation (all roles)
Cross-task knowledge accumulation. Coordinator creates `wisdom/` directory at session init.
**Directory**:
```
<session-folder>/wisdom/
+-- learnings.md # Patterns and insights
+-- decisions.md # Design and strategy decisions
+-- issues.md # Known risks and issues
```
**Worker load** (Phase 2): Extract `Session: <path>` from task description, read wisdom files.
**Worker contribute** (Phase 4/5): Write discoveries to corresponding wisdom files.
### Role Isolation Rules
| Allowed | Prohibited |
|---------|-----------|
| Process own prefix tasks | Process other role's prefix tasks |
| SendMessage to coordinator | Directly communicate with other workers |
| Use tools appropriate to responsibility | Create tasks for other roles |
| Call discuss/explore subagents | Modify resources outside own scope |
| Fast-advance simple successors | Spawn parallel worker batches |
| Report capability_gap to coordinator | Attempt work outside scope |
Coordinator additionally prohibited: directly write/modify deliverable artifacts, call implementation subagents directly, directly execute analysis/test/review.
---
## Cadence Control
**Beat model**: Event-driven, each beat = coordinator wake -> process -> spawn -> STOP.
```
Beat Cycle (single beat)
======================================================================
Event Coordinator Workers
----------------------------------------------------------------------
callback/resume --> +- handleCallback -+
| mark completed |
| check pipeline |
+- handleSpawnNext -+
| find ready tasks |
| spawn workers ---+--> [Worker A] Phase 1-5
| (parallel OK) --+--> [Worker B] Phase 1-5
+- STOP (idle) -----+ |
|
callback <-----------------------------------------+
(next beat) SendMessage + TaskUpdate(completed)
======================================================================
Fast-Advance (skips coordinator for simple linear successors)
======================================================================
[Worker A] Phase 5 complete
+- 1 ready task? simple successor? --> spawn Worker B directly
+- complex case? --> SendMessage to coordinator
======================================================================
```
**Pipelines are dynamic**: Unlike v4's predefined pipeline beat views (spec-only, impl-only, etc.), team-coordinate pipelines are generated per-task from the dependency graph. The beat model is the same -- only the pipeline shape varies.

## Coordinator Spawn Template
### Standard Worker (single-task role)
```
Task({
subagent_type: "general-purpose",
description: "Spawn <role> worker",
team_name: <team-name>,
name: "<role>",
run_in_background: true,
prompt: `You are team "<team-name>" <ROLE>.
## Primary Instruction
All your work MUST be executed by calling Skill to get role definition:
Skill(skill="team-coordinate", args="--role=<role> --session=<session-folder>")
Current requirement: <task-description>
Session: <session-folder>
## Role Guidelines
- Only process <PREFIX>-* tasks, do not execute other role work
- All output prefixed with [<role>] tag
- Only communicate with coordinator
- Do not use TaskCreate to create tasks for other roles
- Before each SendMessage, call mcp__ccw-tools__team_msg to log
- After task completion, check for fast-advance opportunity (see SKILL.md Phase 5)
## Workflow
1. Call Skill -> get role definition and execution logic
2. Follow role.md 5-Phase flow
3. team_msg + SendMessage results to coordinator
4. TaskUpdate completed -> check next task or fast-advance`
})
```
### Inner Loop Worker (multi-task role)
```
Task({
subagent_type: "general-purpose",
description: "Spawn <role> worker (inner loop)",
team_name: <team-name>,
name: "<role>",
run_in_background: true,
prompt: `You are team "<team-name>" <ROLE>.
## Primary Instruction
All your work MUST be executed by calling Skill to get role definition:
Skill(skill="team-coordinate", args="--role=<role> --session=<session-folder>")
Current requirement: <task-description>
Session: <session-folder>
## Inner Loop Mode
You will handle ALL <PREFIX>-* tasks in this session, not just the first one.
After completing each task, loop back to find the next <PREFIX>-* task.
Only SendMessage to coordinator when:
- All <PREFIX>-* tasks are done
- A consensus_blocked HIGH occurs
- Errors accumulate (>= 3)
## Role Guidelines
- Only process <PREFIX>-* tasks, do not execute other role work
- All output prefixed with [<role>] tag
- Only communicate with coordinator
- Do not use TaskCreate to create tasks for other roles
- Before each SendMessage, call mcp__ccw-tools__team_msg to log
- Use subagent calls for heavy work, retain summaries in context`

## Session Resume
Coordinator supports `--resume` / `--continue` for interrupted sessions:
1. Scan `.workflow/.team/TC-*/team-session.json` for active/paused sessions
2. Multiple matches -> AskUserQuestion for selection
3. Audit TaskList -> reconcile session state <-> task status
4. Reset in_progress -> pending (interrupted tasks)
5. Rebuild team and spawn needed workers only
6. Create missing tasks with correct blockedBy
7. Kick first executable task -> Phase 4 coordination loop
---
## Error Handling
| Scenario | Resolution |
|----------|------------|
| Unknown --role value | Check if `<session>/roles/<role>.md` exists; error with message if not |
| Missing --role arg | Orchestration Mode -> coordinator |
| Dynamic role file not found | Error with expected path, coordinator may need to regenerate |
| Built-in role file not found | Error with expected path |
| Command file not found | Fallback to inline execution |
| Discuss subagent fails | Role proceeds without discuss, logs warning |
| Explore cache corrupt | Clear cache, re-explore |
| Fast-advance spawns wrong task | Coordinator reconciles on next callback |
| Session path not provided | Auto-discover from `.workflow/.team/TC-*/team-session.json` |
| capability_gap reported | Coordinator generates new role via handleAdapt |
