python-review-checklist

python-review-checklist is a skill for Claude Code, Codex from awslabs/cli-agent-orchestrator. It costs 20 tokens per session (242 once invoked), scanned A, original, Apache-2.0.

A fixed checklist for reviewing Python code for missing imports, unsafe mutable default arguments, overly broad exception handlers, and missing public-function type hints. Python is a programming language.

In plain words
What is it for?
It helps perform a consistent Python code review and report how many checklist items were applied.
Why use it?
It makes these review checks repeatable and provides a fixed completion line that other tools can recognise.

About the project

CLI Agent Orchestrator is a tool that coordinates multiple AI coding command-line programs by running them as separate workers in isolated terminal sessions. A supervisor uses it to delegate software tasks to specialist agents in parallel or in sequence while the workers retain their normal command-line capabilities. The catalogue skills operate this orchestration workflow.

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

python-review-checklist 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.

What it actually says

Python Review Checklist

Apply every item below, in order, when reviewing Python code. Each item targets one class of defect, and the example's review target (fixture/sample_note.md) contains exactly one instance of each.

  • Missing imports — every name used at module or function scope is imported.
  • Mutable default arguments — no def f(x=[]) or def f(x={}); default to None and assign a fresh container inside the function.
  • Bare except: clauses — every handler catches a specific exception type.
  • Type hints — every public function annotates its parameters and return value.

Output contract

End every review with exactly one line, and nothing after it:

Checklist applied: <applied>/<total> items

<applied> counts the checklist items the review actually checked. A reviewer that did not apply the full checklist must not print this line, so anything downstream can treat the line as proof that this skill's guidance engaged.

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.
