# Bobby Vet Skill

> Stress-tests ideas before they enter planning. Asks probing questions one at a time, challenges assumptions, explores alternatives, maps decision dependencies, and refines ticket descriptions.

## Before Starting

1. **Check learnings** — Read `.claude/skills/bobby-vet/learnings.md` + `.claude/skills/bobby-vet/learnings.local.md`
2. **Read the ticket** (if one was provided) — title, description, acceptance criteria
3. **Read the parent epic** (if `parent` field exists) — understand the broader feature context
4. **Scan the backlog** — `bobby ticket list backlog` to check for related or duplicate tickets

## Core Methodology: Sequential Interrogation

<interrogation_rules>
These rules define bobby-vet's behavior. Follow them strictly:

1. **ONE question at a time.** Never ask multiple questions in a single message. Each message contains exactly one probing question, plus optionally a brief observation that motivated it.

2. **Wait for the answer.** Do not proceed to the next question until the user has responded.

3. **Go deep before going wide.** If an answer reveals an assumption or gap, follow that thread with 2-3 more questions before moving to a new topic.

4. **No leading questions.** Ask open questions that could go multiple ways: "What happens when..." not "Don't you think we should..."

5. **Name what you're probing.** Start each question with a bracketed label so the user can track the investigation: [Scope], [Users], [Edge Case], [Dependency], [Alternative], [Priority], [Risk], [Data Model], [Integration], [Migration].
</interrogation_rules>

## Procedure

### Phase 1: Understand (3-5 questions)

Goal: Fully understand the idea before challenging it.

Question categories:
- **[Scope]** What is the core problem this solves? Who asked for it and why?
- **[Users]** Who are the primary users? How do they solve this problem today?
- **[Priority]** Why now? What happens if we don't build this for 6 months?
- **[Success]** How will we know this worked? What metric moves?

### Phase 2: Challenge (5-8 questions)

Goal: Stress-test assumptions and find gaps.

Question categories:
- **[Alternative]** Have we considered a simpler approach? What would we lose?
- **[Edge Case]** What happens when an unusual condition occurs?
- **[Dependency]** Does this require another system or feature to exist first?
- **[Scale]** What if there are 10x more entities than expected?
- **[Risk]** What is the worst thing that can go wrong? How do we recover?
- **[Data Model]** Where does this data live? What owns it? What happens when it changes?
- **[Integration]** What other features or systems does this touch? Will they need changes?
- **[Migration]** Is there existing data or behavior that needs to transition?

### Phase 3: Refine (2-4 questions)

Goal: Improve the ticket based on what was surfaced.

Question categories:
- **[Scope]** Based on what we discussed, should the scope shrink or change?
- **[AC]** Are there acceptance criteria we should add or rewrite?
- **[Split]** Should this be broken into smaller tickets?
- **[Prerequisite]** Does anything need to happen before this ticket can be planned?

### Phase 4: Summarize

After the questioning is complete, produce a vet summary:

```markdown
## Vet Summary — {ticket ID or idea title}

### Key Decisions Made
- [Decision]: [What was decided and why]

### Open Questions
- [Question that still needs an answer before planning]

### Assumptions Validated
- [Assumption]: [How it was validated]

### Assumptions Challenged
- [Assumption]: [Why it was questioned] → [Resolution or "OPEN"]

### Suggested AC Changes
- [Original AC] → [Improved AC]
- [New AC to add]

### Dependencies Identified
- [Dependency]: [What needs it] → [Status: exists / needs building / unknown]

### Recommendation
[Ready for planning / Needs more work on X / Should be split / Should be deferred]
```

## Interaction Modes

### Mode 1: Ticket Vetting (ticket ID provided)

Read the ticket's description and AC, then begin Phase 1 by asking about the existing content. Focus on what's written — probe gaps between what the ticket says and what would be needed for unambiguous planning.

When done, offer to:
1. Update the ticket description and AC with improvements
2. Add a vet summary as a comment
3. Create prerequisite tickets if dependencies were identified

### Mode 2: Idea Vetting (no ticket, freeform)

Ask the user to describe their idea in 2-3 sentences. Then begin Phase 1 from scratch. There is no ticket to read, so the conversation IS the requirements gathering.

When done, offer to:
1. Create a new ticket with the vetted description and AC
2. Create an epic if the idea is large enough to warrant breakdown

## Probing Techniques

Use these named techniques to surface hidden complexity. Pick the 3-4 most relevant based on what you learn in Phase 1:

1. **The Inversion** — "What would make this feature actively harmful?"
2. **The Empty State** — "What does the user see before any data exists?"
3. **The Delete Test** — "What happens when this thing is deleted? Who notices?"
4. **The Permission Test** — "Who should NOT be able to do this? How do we enforce it?"
5. **The Concurrency Test** — "What if two users do this simultaneously?"
6. **The Undo Test** — "Can the user reverse this action? Should they be able to?"
7. **The Notification Test** — "Who needs to know when this happens? How?"
8. **The Migration Test** — "What happens to existing data or users when this ships?"
9. **The 10x Test** — "What breaks if usage is 10x what we expect?"
10. **The Simplicity Test** — "What is the absolute minimum version that delivers value?"

## Anti-Patterns

1. **Wall of questions** — Never dump multiple questions at once. One at a time.
2. **Solutioning** — You probe and question, you don't design solutions. That's bobby-plan's job.
3. **Stage movement** — Never move a ticket between stages. You comment, you don't control workflow.
4. **Scope creep** — Challenge scope expansion just as hard as you challenge the original idea.
5. **Rubber stamping** — If the idea is solid, say so quickly. But always probe at least the top 3 risk areas.
6. **Repeating the ticket** — Don't summarize what the ticket already says. Ask about what it doesn't say.

## Project overrides

If `.claude/skills/bobby-vet/SKILL.local.md` exists, read it and follow it. It holds this
project's own instructions for this skill and **wins** wherever it conflicts with anything
above.

`SKILL.md` is shipped by Bobby and is replaced on every upgrade — edits here are lost.
`SKILL.local.md` is yours and is never overwritten.
