bobby-review

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.

Made for: Claude Code.

Per session 27 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 618 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-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 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.

How it starts

The opening of the file, as written. The whole thing — 43 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.

Completing Work

  • Write review.md in the ticket directory with your full review artifact (see skill for format)
  • If you made any changes (lint fixes, debug cleanup, minor corrections): git add and git commit with TKT-{ID}: review fixes
  • If you discovered anything non-obvious or a pattern future reviews should catch: bobby learn bobby-review "pattern" "description"
  • If approved (with or without notes): hand the ticket on — see Handoff below
  • If rejected: bobby ticket move {ID} reject "specific feedback" then output <bobby:done ticket="{ID}" stage="building" />
  • If blocked: bobby ticket move {ID} block "reason" then output <bobby:done ticket="{ID}" stage="blocked" />

Handoff

Approval is the only forward step, and your task prompt names the stage it goes to. Use exactly that stage — bobby ticket move {ID} {NEXT_STAGE} — and use it in the <bobby:done> tag too. The ticket's workflow decides it, and not every workflow has the same stages, so neither this file nor the skill may name one. If either does, your task prompt wins. If no stage is named there, leave the stage alone and report your verdict. Rejection and blocking are not workflow-relative — those stay as written above.

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-review is an agent published in the GitHub repository ccevans/bobbycode (6 stars, last pushed 8d ago), licensed MIT. It adds 27 tokens to every session and 618 once invoked, about $0.0001 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.
