# Team Tech Debt Systematic tech debt governance: scan -> assess -> plan -> fix -> validate. 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`. ## Architecture ``` Skill(skill="team-tech-debt", args="task description") | SKILL.md (this file) = Router | +--------------+--------------+ | | no --role flag --role <name> | | Coordinator Worker roles/coordinator/role.md roles/<name>/role.md | +-- analyze → dispatch → spawn workers → STOP | +-------+-------+-------+-------+ v v v v v [team-worker agents, each loads roles/<role>/role.md] scanner assessor planner executor validator ``` ## Role Registry | Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | — | — | | scanner | [roles/scanner/role.md](roles/scanner/role.md) | TDSCAN-* | false | | assessor | [roles/assessor/role.md](roles/assessor/role.md) | TDEVAL-* | false | | planner | [roles/planner/role.md](roles/planner/role.md) | TDPLAN-* | false | | executor | [roles/executor/role.md](roles/executor/role.md) | TDFIX-* | true | | validator | [roles/validator/role.md](roles/validator/role.md) | TDVAL-* | 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**: `TD` - **Session path**: `.workflow/.team/TD-<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**: 3 ## 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 Tech debt follows a discovery-to-fix pipeline. Scanner is broad/fast, later stages need deeper reasoning. | Role | reasoning_effort | Rationale | |------|-------------------|-----------| | scanner | medium | Broad codebase scan, pattern matching over deep analysis | | assessor | high | Severity assessment requires understanding impact and risk | | planner | high | Remediation planning must prioritize and sequence fixes | | executor | high | Code fixes must preserve behavior while removing debt | | validator | medium | Validation follows defined acceptance criteria | ### Pipeline Pattern: Scanner Results Inform Downstream Scanner discoveries flow through the pipeline — each stage narrows and refines: 1. TDSCAN produces broad debt inventory 2. TDEVAL assesses and prioritizes (filters low-impact items) 3. TDPLAN creates sequenced fix plan from assessed items 4. TDFIX implements fixes per plan 5. TDVAL validates fixes against original debt findings ## User Commands | Command | Action | |---------|--------| | `check` / `status` | View execution status graph | | `resume` / `continue` | Advance to next step | | `--mode=scan` | Run scan-only pipeline (TDSCAN + TDEVAL) | | `--mode=targeted` | Run targeted pipeline (TDPLAN + TDFIX + TDVAL) | | `--mode=remediate` | Run full pipeline (default) | | `-y` / `--yes` | Skip confirmations | ## Specs Reference - [specs/pipelines.md](specs/pipelines.md) — Pipeline definitions and task registry ## Session Directory ``` .workflow/.team/TD-<date>-<slug>/ ├── .msg/ │ ├── messages.jsonl # Team message bus │ └── meta.json # Pipeline config + role state snapshot ├── scan/ # Scanner output ├── assessment/ # Assessor output ├── plan/ # Planner output ├── fixes/ # Executor output ├── validation/ # Validator output └── wisdom/ # Cross-task knowledge ``` ## v4 Agent Coordination ### Message Semantics | Intent | API | Example | |--------|-----|---------| | Queue supplementary info (don't interrupt) | `send_message` | Send scan findings to running assessor | | Assign fix from remediation plan | `followup_task` | Assign TDFIX task from planner output | | 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 meta.json active tasks // 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: "TDSCAN-001", message: "..." })` -- send additional scan scope to scanner - `followup_task({ target: "TDFIX-001", message: "..." })` -- assign fix task from planner output - `close_agent({ target: "TDVAL-001" })` -- cleanup after validation ## 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 | | Scanner finds no debt | Report clean codebase, skip to summary |
