Skill profile
thermos
Runs two parallel Cursor subagents — a deep correctness/security audit and a strict maintainability rubric — and synthesizes both into one prioritized branch review.
What it actually does
- Runs two subagents in parallel over a diff: `thermo-nuclear-review` (bugs, breakages, security, devex, feature-gate leaks) and `thermo-nuclear-code-quality-review` (a strict maintainability rubric — code-judo, a 1k-line rule, spaghetti, boundary violations), then synthesizes deduplicated, prioritized findings.
When to use it — and when not to
Use it when
- You want a deliberately harsh, deep review of a branch before merging — beyond what a general-purpose `/review` gives you.
Not for
- A quick sanity check is enough — the built-in `/review` or `/review-bugbot` are lighter-weight for that.
Agent compatibility
- Cursor
Cursor-native plugin — parallel subagents and Cursor's own hook/plugin system, not a portable SKILL.md.
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
Requirements and operational surface
Depends on
- Cursor subagents
What it actually does at runtime
- Reads `git diff` and the full contents of changed files
- Runs two parallel subagent passes; no writes or network calls documented
Related skills
- review-agentThe equivalent bundled review option on Codex, far lighter-weight than thermos.
Overlap and alternatives
- Cursor Team Kitcursor-team-kit bundles the same thermo-nuclear-code-quality-review skill as one of its 17 — installing both gets you that reviewer twice.
Evidence and provenance
Maintained by Cursor (official). Primary source: cursor/plugins — thermos, last checked against this page’s claims on . This page summarizes and analyzes that source — it isn’t a copy of its SKILL.md or README, and installation happens at the source, not here.
