IdoCohen560 Bug Triage
This skill processes the open bug backlog into a prioritised, sprint-assigned action list. It distinguishes between severity (how bad is the impact?) and priority (how urgently must we fix it?), detects systemic trends, and ensures no critical bug is lost between sprints.
Output: production/qa/bug-triage-[date].md
When to run:
- Sprint start — assign open bugs to the new sprint or backlog
- After
/team-qacompletes and new bugs have been filed - When the bug count crosses 10+ open items
1. Parse Arguments
Modes:
/bug-triage sprint— triage against the current sprint; assign fixable bugs to the sprint backlog; defer the rest/bug-triage full— full triage of all bugs regardless of sprint scope/bug-triage trend— trend analysis only (no assignment); read-only report- No argument — run sprint mode if a current sprint exists, else full mode
2. Load Bug Backlog
Step 2a — Discover bug files
Glob for bug reports in priority order:
production/qa/bugs/*.md— individual bug report files (preferred format)production/qa/bugs.md— single consolidated bug log (fallback)- Any
production/qa/qa-plan-*.md"Bugs Found" table (last resort)
If no bug files found:
"No bug files found in
production/qa/bugs/. If bugs are tracked in a different location, adjust the glob pattern. If no bugs exist yet, there is nothing to triage."
Stop and report. Do not proceed if no bugs exist.
Step 2b — Load sprint context
Read the most recently modified file in production/sprints/ to understand:
- Current sprint number / name
- Stories in scope (for assignment target)
- Sprint capacity constraints (if noted)
If no sprint file exists: note "No sprint plan found — assigning to backlog only."
Step 2c — Load severity reference
Read .claude/docs/coding-standards.md for severity/priority definitions if they
exist. If they do not exist, use the standard definitions in Step 3.
3. Classify Each Bug
For each bug, extract or infer:
Severity (impact of the bug)
| Severity | Definition |
|---|---|
| S1 — Critical | Game crashes, data loss, or complete feature failure. Cannot proceed past this point. |
| S2 — High | Major feature broken but game is still playable. Significant wrong behaviour. |
| S3 — Medium | Feature degraded but a workaround exists. Minor wrong behaviour. |
| S4 — Low | Visual glitch, cosmetic issue, typo. No gameplay impact. |
Priority (urgency of the fix)
| Priority | Definition |
|---|---|
| P1 — Fix this sprint | Blocks QA, blocks release, or is regression from last sprint |
| P2 — Fix soon | Should be resolved before the next major milestone |
| P3 — Backlog | Would be good to fix, but no active blocking impact |
| P4 — Won't fix / Deferred | Accepted risk or out of scope for current product scope |
Assignment
For each P1/P2 bug in sprint mode:
- Identify which story or epic the fix belongs to
- Check whether the current sprint has remaining capacity
- If capacity exists: assign to sprint (
Sprint: [current]) - If capacity is full: flag as
Priority overflow — consider pulling from sprint
For full mode: assign all P1 to current sprint, P2 to next sprint estimate,
P3+ to backlog.
Deviation check
Flag bugs that suggest systematic problems:
- 3+ bugs from the same system in the same sprint → "Potential design or implementation quality issue in [system]"
- 2+ S1/S2 bugs in the same story → "Story may need to be reopened and re-reviewed before shipping"
- Bug filed against a story marked Complete → "Regression in completed story — story should be re-opened in sprint tracking"
4. Trend Analysis
After classifying all bugs, generate trend metrics:
Volume trends
- Total open bugs: [N]
- Opened this sprint: [N]
- Closed this sprint: [N]
- Net change: [+N / -N]
System hot spots
- Which system has the most open bugs?
- Which system has the highest S1/S2 ratio?
Age analysis
- How many bugs are older than 2 sprints?
- Are any S1/S2 bugs un-assigned (sprint = none)?
Regression indicator
- Any bugs filed against previously-completed stories?
- Count: [N] regression bugs (story reopened implied)
5. Generate Triage Report
# Bug Triage Report
> **Date**: [date]
> **Mode**: [sprint | full | trend]
> **Generated by**: /bug-triage
> **Open bugs processed**: [N]
> **Sprint in scope**: [sprint name, or "N/A"]

## Triage Summary
| Priority | Count | Notes |
|----------|-------|-------|
| P1 — Fix this sprint | [N] | [N] assigned to sprint, [N] overflow |
| P2 — Fix soon | [N] | Scheduled for next sprint |
| P3 — Backlog | [N] | Deferred |
| P4 — Won't fix | [N] | Accepted risk |
**Critical (S1/S2) unfixed count**: [N]

## P1 Bugs — Fix This Sprint
| ID | System | Severity | Summary | Assigned to | Story |
|----|--------|----------|---------|-------------|-------|
| BUG-NNN | [system] | S[1-4] | [one-line description] | [sprint] | [story path] |
---
## P2 Bugs — Fix Soon
| ID | System | Severity | Summary | Target Sprint |
|----|--------|----------|---------|---------------|
| BUG-NNN | [system] | S[1-4] | [one-line description] | Sprint [N+1] |
---
## P3/P4 Bugs — Backlog / Won't Fix
| ID | System | Severity | Summary | Disposition |
|----|--------|----------|---------|-------------|
| BUG-NNN | [system] | S4 | [one-line description] | Backlog |
---
## Systemic Issues Flagged
[List any patterns from Step 3 deviation check, or "None identified."]
---
## Trend Analysis
**Volume**: [N] open / [+N] net change this sprint
**Hot spot**: [system with most bugs]
**Regressions**: [N] bugs against completed stories
**Aged bugs (>2 sprints old)**: [N]
[If N aged S1/S2 bugs > 0:]
> ⚠️ [N] high-severity bugs have been open for more than 2 sprints without
> assignment. These represent accepted risk that should be explicitly reviewed.

## Recommended Actions
1. [Most urgent action — usually "fix P1 bugs before QA hand-off"]
2. [Second action — usually "investigate [hot spot system] quality"]
3. [Third action — optional improvement]
6. Write and Gate
Present the report in conversation, then ask:
"May I write this triage report to production/qa/bug-triage-[date].md?"
Write only after approval.
After writing:
- If any S1 bugs are unassigned: "S1 bugs must be assigned before the sprint
can be considered healthy. Run
/sprint-statusto see current capacity." - If regression bugs exist: "Regressions found — consider re-opening the
affected stories in sprint tracking and running
/smoke-checkto re-gate." - If no P1 bugs exist: "No P1 bugs — build is in good shape for QA hand-off." Verdict: COMPLETE — triage report written.
If user declined write: Verdict: BLOCKED — user declined write.
Collaborative Protocol
- Never close or mark bugs Won't Fix without user approval — surface them as P4 candidates and ask: "Are these acceptable as Won't Fix?"
- Never auto-assign to a sprint at capacity — flag overflow and let the sprint owner decide what to pull
- Severity is objective; priority is a team decision — present severity classifications as recommendations, not mandates
- Trend data is informational — do not block work on trend findings alone; surface them as observations
