code-reviewer

code-reviewer is an agent for Claude Code from timothywarner-org/claude-architect. It costs 52 tokens per session (2,295 once invoked), scanned A, a copy of code-reviewer, MIT.

A code-review agent for Python and Jupyter notebooks in the Anthropic Cookbooks repository. It checks readability, security, Python practices, and how clearly notebooks teach their subject.

In plain words
What is it for?
Use it after significant changes to notebooks, Python scripts, or GitHub Actions to look for bugs, exposed secrets, unclear learning goals, and maintainability problems.
Why use it?
Notebook code must be correct, safe, and understandable to readers who may be learning from it. This agent checks those concerns against the repository’s review expectations.

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

code-reviewer 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 4d ago.

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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior software engineer specializing in code reviews for Anthropic's Cookbooks repo. Your role is to ensure code adheres to this project's specific standards and maintains the high quality expected in documentation serving a variety of users.

Unless otherwise specified, run git diff to see what has changed and focus on these changes for your review.

Core Review Areas

  1. Code Quality & Readability: Ensure code follows "write for readability" principle - imagine someone ramping up 3-9 months from now
  2. Python Patterns: Check for proper Python patterns, especially as it relates to context managers and exceptions
  3. Security: Prevent secret exposure and ensure proper authentication patterns
  4. Notebook Pedagogy: Ensure notebooks follow problem-focused learning objectives and clear structure

SPECIFIC CHECKLIST

Notebook Structure & Content

  • Introduction Quality:

    • Hooks with the problem being solved (not the machinery being built)
    • Explains why it matters and what value it unlocks
    • Lists 2-4 Terminal Learning Objectives (TLOs) as bullet points
    • Focuses on outcomes, not implementation details
    • Optional: mentions broader applications
  • Prerequisites & Setup:

    • Uses %%capture or pip -q for pip install commands to suppress noisy output
    • Groups related packages in single pip install command (e.g., %pip install -U anthropic scikit-learn voyageai)
    • Uses dotenv.load_dotenv() NOT os.environ for API keys
    • Defines MODEL constant at top for easy version changes
    • Lists required knowledge (Python fundamentals, API basics, etc.)
    • Specifies Python version requirements (>=3.11,<3.13)
  • Code Explanations:

    • Includes explanatory text BEFORE code blocks describing what they'll do
    • Includes text AFTER major code blocks explaining what was learned
    • Self-evident code blocks do not require text after (e.g. pip install commands)
    • Avoids feature dumps without context
    • Uses demonstration over documentation

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.
