Debt Triage — Backlog Review and Prioritization

Overview

Review the debt backlog, verify items are still relevant, re-prioritize based on current state, close resolved items, and present recommendations to the PM.

Announce at start: "I'm using the coordinator:debt-triage skill to review the debt backlog."

When to Trigger

• On demand (PM or EM invocation)
• When debt backlog exceeds 20 open items (surfaced by weekly-architecture-audit with escalating insistence — mild concern at >20, visible Patrik disappointment at >30, coffee-down intervention at >40 — and by session-start)
• After a major refactor that may have resolved multiple debt items

The Process

This is an EM-PM conversation, not a dispatched agent. The EM reads the backlog, applies judgment, and presents recommendations.

Step 1: Read Current State

1. Read tasks/debt-backlog.md
2. Summarize: total open items, breakdown by severity (P0/P1/P2), breakdown by system
3. Identify the oldest open items (stalest debt)

Step 1b: Cross-reference bug backlog

Also read tasks/bug-backlog.md (if it exists). Flag any BS-* entries that overlap with open DCH-/WAA- items by file path or description similarity. When overlap is found, populate the Cross-ref field on both entries (e.g., Cross-ref: BS-2026-03-18-1 on the debt item, Cross-ref: WAA-2026-03-19-1 on the bug item). Present overlaps to PM for deduplication decision.

Step 2: Verify Relevance (Haiku agents)

Dispatch Haiku agents to verify each open item against the current code. This is mechanical read-and-confirm work — no judgment needed. Group items by system for efficient dispatch (one Haiku per system).

Each Haiku agent receives a list of items for its system and:

1. Checks if the referenced code has changed since the finding was logged

   git log --since="<finding-date>" -- <file-path>
   

2. Reads the cited file:line to confirm the issue still exists
3. Returns a verdict per item: still-open / already-fixed / partially-addressed

The coordinator then categorizes:

• Items the Haiku marked already-fixed: mark as no-longer-applicable
• Items marked still-open: item remains open
• Items marked partially-addressed: update the description based on Haiku's report

Why Haiku: 12 of 16 items in the 2026-03-19 triage were already fixed. Haiku verification costs minutes; dispatching Sonnet executors on ghost debt costs significantly more.

Step 3: Re-Prioritize

Based on current state:

• Items blocking other work → escalate to P0
• Items in systems with grade D/F → escalate to P1
• Items in systems recently audited as A/B → may deprioritize to P2
• Items >30 days old with no activity → flag for PM attention

Step 4: Group for Execution

Group remaining items by system for efficient batch execution:

## Triage Results

### Closed (no longer applicable): N items
| ID | Reason |
|----|--------|

### Recommended for immediate action: N items
| ID | System | Severity | Description | Effort |
|----|--------|----------|-------------|--------|

### Can defer: N items
| ID | System | Severity | Reason to defer |
|----|--------|----------|----------------|

### Needs PM decision (YAGNI/scope): N items
| ID | System | Description | Question |
|----|--------|-------------|----------|

Step 5: Present to PM

Present the triage results and ask for:

1. Approval to close no-longer-applicable items
2. YAGNI/scope decisions on flagged items
3. Prioritization of immediate-action items
4. Agreement on deferral reasoning

Step 6: Update Backlog

After PM decisions:

1. Close resolved items (status: closed — [reason])
2. Update priorities per PM direction
3. Remove items PM declares YAGNI
4. Update header counts
5. Commit:

   git add tasks/debt-backlog.md
   git commit -m "debt-triage: reviewed N items, closed M, N remain open"
   

Notes

• The EM triages severity; only the PM removes items (YAGNI call)
• Items verified as no-longer-applicable can be closed by EM without PM approval
• This skill produces no code changes — it's a backlog management activity
