What it does

Thermo Nuclear Code Quality Review is an agent skill from cursor/plugins, published by the product's own GitHub organization. Run an extremely strict maintainability review for abstraction quality, giant files, and spaghetti-condition growth. Use for a thermo-nuclear code quality review, thermonuclear review, deep code quality audit, or especially harsh maintainability review.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code quality. The repository describes itself as: Cursor plugin specification and official plugins.

When your agent uses it

  • A thermo-nuclear code quality review
  • Thermonuclear review
  • Deep code quality audit
  • Especially harsh maintainability review

Example prompts

  • “/thermo-nuclear-code-quality-review”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Be ambitious about structural simplification.
  2. Do not let a PR push a file from under 1k lines to over 1k lines without a very strong reason.
  3. Do not allow random spaghetti growth in existing code.
  4. Bias toward cleaning the design, not just accepting working code.
  5. Prefer direct, boring, maintainable code over hacky or magical code.
  6. Push hard on type and boundary cleanliness when they affect maintainability.
  7. Keep logic in the canonical layer and reuse existing helpers.
  8. Treat unnecessary sequential orchestration and non-atomic updates as design smells when the cleaner structure is obvious.

What it can do on your machine

Read from SKILL.md and the folder at commit ccb5507. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Thermo Nuclear Code Quality Review loads about 3.1k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 1,766 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,766 words (~3,110 tokens).

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