Bug Report
Phase 1: Parse Arguments
Determine the mode from the argument:
- No keyword → Description Mode: generate a structured bug report from the provided description
analyze [path]→ Analyze Mode: read the target file(s) and identify potential bugsverify [BUG-ID]→ Verify Mode: confirm a reported fix actually resolved the bugclose [BUG-ID]→ Close Mode: mark a verified bug as closed with resolution record
If no argument is provided, ask the user for a bug description before proceeding.
Phase 2A: Description Mode
- Parse the description for key information: what broke, when, how to reproduce it, and what the expected behavior is.
- Search the codebase for related files using Grep/Glob to add context (affected system, likely files).
- Draft the bug report:
# Bug Report
## Summary
**Title**: [Concise, descriptive title]
**ID**: BUG-[NNNN]
**Severity**: [S1-Critical / S2-High / S3-Medium / S4-Low]
**Priority**: [P1-Fix this sprint / P2-Fix soon / P3-Backlog / P4-Won't fix]
**Status**: Open
**Reported**: [Date]
**Reporter**: [the reporter's name as the user gives it, else `—`; never an email address or account ID taken from the session]
## Classification
- **Category**: [Gameplay / UI / Audio / Visual / Performance / Crash / Network]
- **System**: [Which game system is affected — when the bug spans systems, the one whose code must change; the others go under Related systems]
- **Frequency**: [Always / Often (>50%) / Sometimes (10-50%) / Rare (<10%)]
- **Regression**: [Yes/No/Unknown -- was this working before?]
## Environment
- **Build**: [Version or commit hash]
- **Platform**: [OS, hardware if relevant]
- **Scene/Level**: [Where in the game]
- **Game State**: [Relevant state -- inventory, quest progress, etc.]
## Reproduction Steps
**Preconditions**: [Required state before starting]
1. [Exact step 1]
2. [Exact step 2]
3. [Exact step 3]
**Expected Result**: [What should happen]
**Actual Result**: [What actually happens]
## Technical Context
- **Likely affected files**: [List of files based on codebase search]
- **Related systems**: [What other systems might be involved]
- **Possible root cause**: [If identifiable from the description]
## Evidence
- **Logs**: [Relevant log output if available]
- **Visual**: [Description of visual evidence]
## Related Issues
- [Links to related bugs or design documents]
## Notes
[Any additional context or observations]The Severity and Priority labels use /bug-triage's S and P numbers and
names, which it parses out of this file. P4-Won't fix is its P4 — Won't fix /
Deferred (an accepted risk), not a wishlist. If you change either ladder, change
.claude/skills/bug-triage/SKILL.md too.
Phase 2B: Analyze Mode
- Read the target file(s) specified in the argument.
- Identify potential bugs: null references, off-by-one errors, race conditions, unhandled edge cases, resource leaks, incorrect state transitions.
- For each potential bug, generate a bug report using the template above, with the likely trigger scenario and recommended fix filled in.
Phase 2C: Verify Mode
Find the bug file by its number, here and in close mode: Glob
production/qa/bugs/BUG-*.md and take the file whose number matches [BUG-ID],
whatever its zero-padding — an older three-digit file with a slug is found by
its number too. If none
matches, stop: "No bug [BUG-ID] in production/qa/bugs/." Verdict: BLOCKED
— no such bug.
Read that file. Extract the reproduction steps and expected result.
- Re-run reproduction steps — use Grep/Glob to check whether the root cause code path still exists as described. If the fix removed or changed it, note the change.
- Run the related test — if the bug's system has a test file in the engine's test root (
tests/Godot,Assets/Tests/Unity,Source/<Module>/Private/Tests/Unreal —.claude/docs/directory-structure.md), run it via Bash withcommands.testfromproject.yaml, narrowed to the affected suite where the runner allows — never a runner line written from memory, which drops the flags the engine needs (gdUnit4 hangs without--remote-debug tcp://127.0.0.1:0) — and report pass/fail.commands.testunset → no test ran: name the unset key and go on to step 3. - Check for regression — grep the codebase for any new occurrence of the pattern that caused the bug.
- Manual verification — when no related test ran (none covers the bug — the usual case where
qa.levelwaives tests —commands.testis unset, or the run did not complete), or the bug's Category is Visual or UI, whose look no automated test checks, ask viaAskUserQuestion: "Did you play the reproduction steps in [bug file] on a build with the fix? Which build?" —
[No longer occurs] / [Still occurs] / [Not played yet].
Record the answer and the build as the user gives them; a changed code path is never taken as their answer.
Produce a verification verdict:
- VERIFIED FIXED — the bug is gone by every check that applies: any related test ran and passed, and, where step 4 asked, the user answered
[No longer occurs]for a named build. With no test run, that play alone is the verification — a manual one, recorded as such:[user], manual, build [X]. A changed code path on its own is never a pass - STILL PRESENT — a related test fails on the bug's case, or the user answered
[Still occurs]; the fix did not resolve the issue - CANNOT VERIFY — step 4 was answered
[Not played yet]: name what is missing or could not run (no related test,commands.testunset, a run that did not complete, a Visual or UI bug), and say that playing the reproduction steps settles it — run/bug-report verify [BUG-ID]again once played
Ask: "May I update production/qa/bugs/[bug file] to set Status: Verified Fixed / Still Present / Cannot Verify?" — naming the file found above, whatever its padding or slug. With the Status, write a Verified by: line under it: [test file(s)] — ran and passed, or [user], manual, build [X] for a manual verification.
If STILL PRESENT: reopen the bug, set Status back to Open, and suggest re-running /hotfix [BUG-ID].
Phase 2D: Close Mode
Read the bug file, found by its number as in verify mode. Confirm Status is Verified Fixed before closing. If status is anything else, stop: "Bug [ID] must be Verified Fixed before it can be closed. Run /bug-report verify [BUG-ID] first."
Show the closure record below and the Status change, then ask: "May I update production/qa/bugs/[bug file] to mark it Closed?" Nothing is written before a yes; on no, stop — the bug stays Verified Fixed.
On yes, append the closure record to the bug file:
## Closure Record
**Closed**: [date]
**Resolution**: Fixed — [one-line description of what was changed]
**Fix commit / PR**: [if known]
**Verified by**: [the verify record's `**Verified by**:` line — the test that ran and passed, or "[user], manual, build [X]"]
**Closed by**: [user]
**Regression test**: [test file path, or "Manual verification" when verify recorded a manual play]
**Status**: ClosedThen update the top-level Status: field to Status: Closed.
After closing, check production/qa/bug-triage-*.md — if the bug appears in an open triage report, note: "Bug [ID] is referenced in the triage report. Run /bug-triage to refresh the open bug count."
Phase 3: Save Report
Present the completed bug report(s) to the user.
Allocate the ID before asking: Glob production/qa/bugs/BUG-*.md, take the
highest number and add 1, zero-padded to four digits (BUG-0001 when there are
none). Several reports in one run (analyze mode) take consecutive IDs from
there, one each — never the same ID twice.
Ask: "May I write this to production/qa/bugs/BUG-[NNNN].md?" For several
reports, ask once and name every file: "May I write these to
production/qa/bugs/BUG-[NNNN].md, production/qa/bugs/BUG-[NNNN+1].md, …?"
If yes, write the file, creating the directory if needed. Verdict: COMPLETE — bug report filed.
If no, stop here. Verdict: BLOCKED — user declined write.
Phase 4: Next Steps
After saving, suggest based on mode:
After filing (Description/Analyze mode):
- Run
/bug-triageto prioritize alongside existing open bugs - If S1 or S2: run
/hotfix [BUG-ID]for emergency fix workflow
After fixing the bug (developer confirms fix is in):
- Run
/bug-report verify [BUG-ID]— confirm the fix actually works before closing - Never mark a bug closed without verification — a fix that doesn't verify is still Open
After verify returns CANNOT VERIFY:
- Play the reproduction steps on a build with the fix, then run
/bug-report verify [BUG-ID]again and answer its question
After verify returns VERIFIED FIXED:
- Run
/bug-report close [BUG-ID]— write the closure record and update status - Run
/bug-triageto refresh the open bug count and remove it from the active list
