# Bug

Applies [CONCEPT_ALIGNMENT](../concepts/CONCEPT_ALIGNMENT.md) and
[CONCEPT_DEFINITION](../concepts/CONCEPT_DEFINITION.md) to a **defect**.
Produces `BUG.md`. Shared persist/track contract:
[../define/overrides.md](../define/overrides.md). Applies
[CONCEPT_SKILL](../concepts/CONCEPT_SKILL.md).

**On invoke:** read [../define/overrides.md](../define/overrides.md).

## Extensions

| Slot | This skill |
|------|------------|
| **Subject** | Bug, regression, or incorrect behaviour |
| **Probes** | Symptom; minimal repro; expected vs actual; impact/severity; suspected area (no deep code dive); **pass criteria**; out of scope; optional parent Story/Task link |
| **Stop condition** | The user has stated repro, expected vs actual, impact, and pass criteria (or explicitly deferred one) and approved the readiness prompt |
| **Alignment / definition artifact** | `BUG.md` (path from WORKSPACE) |
| **Readiness prompt** | "Is this enough to implement the fix?" |
| **Opening** | Thin: "What is broken?" Rich (stack/steps pasted): first question on highest-impact gap |
| **Scope guard** | Defect pass criteria and optional lineage only; keep the loop short |
| **Depth** | Lightweight |
| **Work packages** | Optional Sub-tasks only when packages are truly separate |

## Artifact

```markdown
# Bug: [title]

## Summary
- …

## Repro
1. …

## Expected
- …

## Actual
- …

## Impact
- …

## Suspected area
- …

## Pass criteria
- …   # observable that fails if the defect remains

## Out of scope
- …

## Work packages
1. …   # optional; omit if a single fix commit is enough

## Tracker
- Task: <KEY>
- Sub-tasks: … (if any)
- Branch: <delivery-branch>
- PR: <url or draft url>

## Classification
- Class: bug
- Confidence: high
- Why: explicit /bug

## Workflow
- Template: fix-fast
- Parameters: catalog defaults for fix-fast
- Chain: delivery chain for that template
```

## Inputs

| Input | When present | When absent |
|-------|----------------|-------------|
| Defect report | Apply it as the subject | Ask "What is broken?" once |

Supportive Task or Story links are applied when present.

## Output

`BUG.md` — defect spec plus the fix-fast binding. Outcome: `ready`.

This skill does not name a successor. Apply the workflow transition before the turn ends.
