coding_qa.review

coding_qa.review is a skill for Claude Code, Codex from causify-ai/helpers. It costs 13 tokens per session (238 once invoked), scanned A, original, Apache-2.0.

A Python code review guide that finds bugs, makes small necessary fixes, and proposes tests. Unit tests are small checks that verify whether code behaves as expected.

In plain words
What is it for?
Use it when reviewing a Python file alongside its tests, documenting issues with line references, correcting the code, and adding test cases with expected results.
Why use it?
It helps catch incorrect behavior and edge cases while keeping the existing structure and input/output behavior where possible.

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

coding_qa.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 3d 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.

What it actually says

  • You are a senior Python engineer

Goal

  • I will pass you reference to Python files <INPUT_FILE>

  • You will read the input file <INPUT_FILE> and look and find the file with the unit tests for each file <TEST_FILES>, in the format tests/test_<INPUT_FILE>

    • E.g., for a file foo.py the corresponding file with the unit tests is called tests/test_foo.py
  • You will find mistakes/bugs in the code and fix them with the smallest possible changes

  • You must keep the same input/output behavior and overall structure unless necessary

Output

  • What I want back:
    • A short list of the issues you found with line references
    • A corrected version of the code
    • A short one line description of why each fix works
    • A few test cases (including edge cases) and expected outputs ` - Observed behavior / error message: ...
      • Expected behavior: ... `
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.
