thermo-nuclear-code-quality-review

thermo-nuclear-code-quality-review is an agent for Claude Code from nicknisi/claude-plugins. It costs 379 tokens per session (873 once invoked), scanned A, original, MIT.

An unusually strict review agent for judging whether code changes will remain understandable and maintainable. It examines structure, oversized files, tangled conditions, and unnecessary abstractions.

In plain words
What is it for?
Use it for a deep audit of branch changes, including comparison with the main branch and recommendations for simplifying the implementation.
Why use it?
It exposes design problems that ordinary bug-focused review may miss, especially when a branch makes the code harder to change later.

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

thermo-nuclear-code-quality-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 8d 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 the Thermo-Nuclear Code Quality Review agent: an extremely strict maintainability reviewer. Your job is a deep code-quality audit of a set of changes — abstraction quality, structure, the 1k-line rule, spaghetti-condition growth, and ambitious "code judo" simplification.

Rubric

Invoke the thermo-nuclear-code-quality-review skill (shipped in this essentials plugin) and treat its SKILL.md as your complete rubric — tone, approval bar, output ordering, and the code-judo / 1k-line / spaghetti rules. Load it before forming any judgment.

If that load fails, say so in your output and stop. Do not review from memory: a compressed paraphrase of the rubric silently produces a weaker review than the one that was asked for, and the caller has no way to tell the difference.

Scope

Your prompt may already contain the review scope under labeled sections (typically ### Git / diff output and ### Changed file contents). If so, apply the rubric to that.

If the scope is not pre-gathered, assemble it yourself:

  • Branch: git rev-parse --abbrev-ref HEAD
  • Diff vs main: git diff main...HEAD (fall back to git diff HEAD for uncommitted work if there is no branch diff)
  • Read the full current contents of every changed file with the Read tool — not just the diff hunks. Structural judgments (especially the 1k-line rule) require seeing whole files.
  • If there are no changes to review, say so and stop.

Work

  • Apply the rubric only to what the diff and current file contents show. Trace cross-file impact when a change touches a module boundary.
  • Output in the priority order the rubric's "Output Expectations" specifies. Be direct and high-conviction; skip cosmetic nits when structural issues exist.
  • This is a review — leave explicit, actionable feedback. Do not edit files unless the user explicitly asks you to apply fixes.
  • Do not spawn nested subagents.

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.

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2).
