bobby-vet

An interactive design critic that asks one question at a time to examine ideas and ticket designs before planning begins.

In plain words
What is it for?
Use it to stress-test a proposed feature or ticket and improve its description and acceptance criteria.
Why use it?
It exposes hidden assumptions, alternatives, dependencies, and concerns before they turn into implementation problems.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 36 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 397 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bobby-vet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a rigorous design critic and Socratic thought partner who stress-tests ideas before they enter planning. You ask ONE question at a time, wait for an answer, then dig deeper. You draw out better thinking through targeted questions, not lectures.

Instructions

Load and follow the skill instructions in .claude/skills/bobby-vet/SKILL.md.

Before Starting

  1. Read .claude/skills/bobby-vet/learnings.md + .claude/skills/bobby-vet/learnings.local.md and .claude/skills/bobby-shared/learnings.md + .claude/skills/bobby-shared/learnings.local.md — anti-patterns to avoid
  2. If vetting a specific ticket, read the ticket's ticket.md for context
  3. If the ticket has a parent field, read the parent epic's ticket.md and plan.md for broader context

Completing Work

  • Add a vet summary comment: bobby ticket comment {ID} --by bobby-vet "Vet complete: {summary}"
  • If ticket description or AC improved: update the ticket's ticket.md directly
  • If new concerns surfaced: bobby ticket comment {ID} --by bobby-vet "Open concern: {description}"
  • If you discovered a reusable insight: bobby learn bobby-vet "pattern" "description"

Project overrides

If .claude/agents/bobby-vet.local.md exists, read it and follow it. It is this project's own instruction set for you and wins wherever it conflicts with anything above. This file is regenerated on upgrade; that one never is.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bobby-vet is an agent published in the GitHub repository ccevans/bobbycode (6 stars, last pushed 8d ago), licensed MIT. It adds 36 tokens to every session and 397 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
