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**: `TAO` - **Session path**: `.workflow/.team/TAO--/` - **CLI tools**: `ccw cli --mode analysis` (read-only), `ccw cli --mode write` (modifications) - **Message bus**: `mcp__ccw-tools__team_msg(session_id=, ...)` ## Worker Spawn Template Coordinator spawns workers using this template: ``` spawn_agent({ agent_type: "team_worker", task_name: "", fork_turns: "none", message: `## Role Assignment role: role_spec: /roles//role.md session: session_id: requirement: inner_loop: Read role_spec file (/roles//role.md) to load Phase 2-4 domain instructions. ## Task Context task_id: title: description: pipeline_phase: ## Upstream 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. **Inner Loop roles** (refactorer): Set `inner_loop: true`. **Single-task roles** (analyzer, designer, validator, reviewer): Set `inner_loop: false`. ### Model Selection Guide Architecture optimization is reasoning-intensive. All analysis and design roles need high reasoning effort. | Role | reasoning_effort | Rationale | |------|-------------------|-----------| | analyzer | high | Deep structural analysis of codebase architecture | | designer | high | Architecture redesign requires careful reasoning about tradeoffs | | refactorer | high | Code transformations must preserve correctness | | validator | high | Validation must thoroughly check refactoring correctness | | reviewer | high | Code quality review demands deep understanding | Override in spawn_agent when needed: ``` spawn_agent({ agent_type: "team_worker", task_name: "", fork_turns: "none", reasoning_effort: "high", message: "..." }) ``` ## User Commands | Command | Action | |---------|--------| | `check` / `status` | View execution status graph (branch-grouped), no advancement | | `resume` / `continue` | Check worker states, advance next step | | `revise [feedback]` | Revise specific task + cascade downstream | | `feedback ` | Analyze feedback impact, create targeted revision chain | | `recheck` | Re-run quality check | | `improve [dimension]` | Auto-improve weakest dimension | ## Session Directory ``` .workflow/.team/TAO--/ ├── session.json # Session metadata + status + parallel_mode ├── task-analysis.json # Coordinator analyze output ├── artifacts/ │ ├── architecture-baseline.json # Analyzer: pre-refactoring metrics │ ├── architecture-report.md # Analyzer: ranked structural issue findings │ ├── refactoring-plan.md # Designer: prioritized refactoring plan │ ├── validation-results.json # Validator: post-refactoring validation │ ├── review-report.md # Reviewer: code review findings │ ├── aggregate-results.json # Fan-out/independent: aggregated results │ ├── branches/ # Fan-out mode branch artifacts │ │ └── B{NN}/ │ │ ├── refactoring-detail.md │ │ ├── validation-results.json │ │ └── review-report.md │ └── pipelines/ # Independent mode pipeline artifacts │ └── {P}/ │ └── ... ├── explorations/ │ ├── cache-index.json # Shared explore cache │ └── .md ├── wisdom/ │ └── patterns.md # Discovered patterns and conventions ├── discussions/ │ ├── DISCUSS-REFACTOR.md │ └── DISCUSS-REVIEW.md └── .msg/ ├── messages.jsonl # Message bus log └── meta.json # Session state + cross-role state ``` ## Specs Reference - [specs/pipelines.md](specs/pipelines.md) — Pipeline definitions, task registry, parallel modes ## v4 Agent Coordination ### Message Semantics | Intent | API | Example | |--------|-----|---------| | Queue supplementary info (don't interrupt) | `send_message` | Send codebase patterns to running analyzer | | Assign new work / trigger processing | `followup_task` | Assign fix task to refactorer after review feedback | | 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 session.json active tasks // Reset orphaned tasks (in_progress but agent gone) to pending ``` ### Named Agent Targeting Workers are spawned with `task_name: ""` enabling direct addressing: - `send_message({ target: "ANALYZE-001", message: "..." })` -- queue analysis context without interrupting - `followup_task({ target: "REFACTOR-001", message: "..." })` -- assign fix task after review feedback - `close_agent({ target: "VALIDATE-001" })` -- cleanup by name ### Merged Exploration Pattern For architecture analysis, analyzer may need broad codebase exploration. Consider spawning analyzer with `fork_turns: "all"` when deep structural analysis of interconnected modules is needed: ``` spawn_agent({ agent_type: "team_worker", task_name: "ANALYZE-001", fork_turns: "all", // Share coordinator's codebase context reasoning_effort: "high", message: "..." }) ``` ## Error Handling | Scenario | Resolution | |----------|------------| | Unknown command | Error with available command list | | Role not found | Error with role registry | | CLI tool fails | Worker fallback to direct implementation | | Fast-advance conflict | Coordinator reconciles on next callback | | Completion action fails | Default to Keep Active | | consensus_blocked HIGH | Coordinator creates revision task or pauses pipeline | | Branch fix cycle >= 3 | Escalate only that branch to user, others continue | | max_branches exceeded | Coordinator truncates to top N at CP-2.5 |
