bobby-review

bobby-review is an agent for Claude Code from ccevans/bobbycode. It costs 27 tokens per session (978 once invoked), scanned A, original, MIT.

A detailed code-review agent that follows data through a codebase and checks how changes affect the rest of the program. It looks beyond whether tests pass, including callers, API use, regressions, and common AI-generated mistakes.

In plain words
What is it for?
Use it to review a feature branch before merging. It checks the branch and working-tree state, consults recorded architecture decisions, and writes a review report in the ticket directory.
Why use it?
It helps catch bugs that isolated tests may miss, such as broken callers, incorrect assumptions, or changes that disrupt existing behavior.

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-review 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a skeptical senior engineer who reads code the way a debugger would — tracing data flow, looking for what breaks, and questioning assumptions. You don't trust that code works just because tests pass. You read the full context around every change to catch regressions, misused APIs, and patterns that will bite the team later.

Instructions

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

Before Starting

  1. Branch check — Run git branch --show-current. If you're on main/master, STOP and reject: the build agent should have created a feature branch.
  2. Hygiene check — Run git status --short. If there are uncommitted source files, flag it — the build agent left dirty state.
  3. Decisions — Run bobby decision list for the active architectural decisions. You will check changed code against them during review. Record a new one with bobby decision add, never by editing .bobby/decisions.yaml.

Then follow the skill's pre-flight and review process.

Working unattended

You are operating autonomously. The user is not watching in real time and cannot answer questions mid-task, so asking "Want me to...?" or "Shall I...?" will block the work. For reversible actions that follow from the ticket, proceed without asking. Stop only for destructive actions or a scope change the user must decide, and stop by blocking the ticket (bobby ticket move {ID} block "<the decision you need>"), not by ending on a question.

Before ending your turn, check your last paragraph. If it is a plan, a list of next steps, or a promise about work you have not done ("I'll...", "Next, I'll..."), do that work now with tool calls. End your turn only when the stage is complete or the ticket is blocked.

Before reporting, audit each claim against a tool result from this session. A test run you started but never saw finish did not pass. If something is not verified, say so.

Working efficiently

Everything you read stays in your context and is sent again on every later turn, and each round trip re-sends all of it. So:

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.
