code-review-thermo

code-review-thermo is a skill for Claude Code, Codex from hachej/boring-ui. It costs 32 tokens per session (2,469 once invoked), scanned A, a copy of thermo-nuclear-code-quality-review, MIT.

A strict code-review skill focused on keeping software understandable and maintainable. It examines large files, tangled conditions, weak abstractions, and opportunities to simplify the structure.

In plain words
What is it for?
Use it for deep reviews of branch changes, especially when you want to reconsider the structure, reduce tangled logic, improve modularity, and simplify the implementation without changing its behavior.
Why use it?
It looks beyond individual defects to find design problems that make future changes harder and increase the cost of maintaining the code.

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-review-thermo 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 5d 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.

Thermo-Nuclear Code Quality Review

Use this skill for an unusually strict review focused on implementation quality, maintainability, abstraction quality, and codebase health.

Above all, this skill should push the reviewer to be ambitious about code structure. Do not merely identify local cleanup opportunities. Actively search for "code judo" moves: restructurings that preserve behavior while making the implementation dramatically simpler, smaller, more direct, and more elegant.

Core Prompt

Start from this baseline:

Perform a deep code quality audit of the current branch's changes. Rethink how to structure / implement the changes to meaningfully improve code quality without impacting behavior. Work to improve abstractions, modularity, reduce Spaghetti code, improve succinctness and legibility. Be ambitious, if there is a clear path to improving the implementation that involves restructuring some of the codebase, go for it. Be extremely thorough and rigorous. Measure twice, cut once.

Non-Negotiable Additional Standards

Apply the baseline prompt above, plus these explicit review rules:

  1. Be ambitious about structural simplification.

    • Do not stop at "this could be a bit cleaner."
    • Look for opportunities to reframe the change so that whole branches, helpers, modes, conditionals, or layers disappear entirely.
    • Prefer the solution that makes the code feel inevitable in hindsight.
    • Assume there is often a "code judo" move available: a re-organization that uses the existing architecture more effectively and makes the change dramatically simpler and more elegant.
    • If you see a path to delete complexity rather than rearrange it, push hard for that path.
  2. Do not let a PR push a file from under 1k lines to over 1k lines without a very strong reason.

    • Treat this as a strong code-quality smell by default.
    • Prefer extracting helpers, subcomponents, modules, or local abstractions instead of letting a file sprawl past 1000 lines.
    • If the diff crosses that threshold, explicitly ask whether the code should be decomposed first.
    • Only waive this if there is a compelling structural reason and the resulting file is still clearly organized.
