Team Tech Debt

---
name: team-tech-debt-b71d54574ad2
description: Unified team skill for tech debt identification and remediation. Scans codebase for tech debt, assesses severity, plans and executes fixes with validation. Uses team-worker agent architecture with roles/ for domain logic. Coordinator orchestrates pipeline, workers are team-worker agents. Triggers on "team tech debt".

# 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>
     |                             |

     |
     +-- analyze → dispatch → spawn workers → STOP
                                    |
                    +-------+-------+-------+-------+

           [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

## Shared Constants

- **Session prefix**: `TD`
- **Session path**: `.workflow/.team/TD-<slug>-<date>/`
- **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:

```
Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker for <task-id>",
  team_name: "tech-debt",
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
team_name: tech-debt
requirement: <task-description>
inner_loop: <true|false>

## Progress Milestones
session_id: <session-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})
```

## 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 |

## 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 |
