Structured Bug Reports

!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys automation

Automation mode: Resolve modes.automation (project.local.yaml → project.yaml → default collaborative). Every AskUserQuestion call and every file write follows .claude/docs/automation-modes.md (collaborative asks always · guided major-only · autonomous logs and proceeds; automation_always_ask categories always prompt).

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 bugs
• verify [BUG-ID] → Verify Mode: confirm a reported fix actually resolved the bug
• close [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

1. Parse the description for key information: what broke, when, how to reproduce it, and what the expected behavior is.

2. Search the codebase for related files using Grep/Glob to add context (affected system, likely files).

3. 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

1. Read the target file(s) specified in the argument.

2. Identify potential bugs: null references, off-by-one errors, race conditions, unhandled edge cases, resource leaks, incorrect state transitions.

3. 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.

1. 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.
2. 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 with commands.test from project.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.test unset → no test ran: name the unset key and go on to step 3.
3. Check for regression — grep the codebase for any new occurrence of the pattern that caused the bug.
4. Manual verification — when no related test ran (none covers the bug — the usual case where qa.level waives tests — commands.test is unset, or the run did not complete), or the bug's Category is Visual or UI, whose look no automated test checks, ask via AskUserQuestion: "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.test unset, 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].
