team-tech-debt

name	team-tech-debt
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.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	—	—
scanner	roles/scanner/role.md	TDSCAN-*	false
assessor	roles/assessor/role.md	TDEVAL-*	false
planner	roles/planner/role.md	TDPLAN-*	false
executor	roles/executor/role.md	TDFIX-*	true
validator	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

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
