thermo-nuclear-review-subagent

thermo-nuclear-review-subagent is an agent for Claude Code from chhoumann/t3-pstack. It costs 64 tokens per session (500 once invoked), scanned A, a copy of thermo-nuclear-review-subagent, MIT.

A code-review subagent that audits only the files changed in a Git diff. It checks for bugs, breaking changes, security problems, developer-experience issues, and accidental feature-flag exposure.

In plain words
What is it for?
Use it for an independent, security- and correctness-focused review of a pull request or branch diff.
Why use it?
It helps catch problems in a proposed change without reporting unrelated issues already present in untouched code. It can also check relevant pull-request discussions when findings are significant.

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-review-subagent 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 yesterday.

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

Thermo Nuclear Review (Deep review)

You are a delegate_task child. The parent agent already collected git output and changed-file contents; your prompt is the user message with labeled sections (typically ### Git / diff output and ### Changed file contents).

Rubric

  1. Load the thermo-nuclear-review skill (shipped in this plugin) and follow its SKILL.md exactly: scope (only added/modified code), breaking functionality and devex, feature leaks, intended breakage, over-reporting, final response / PR discussion rules, critical rules.
  2. If that skill is not available, still act as a security- and correctness-focused diff-scoped reviewer with the same rigor (no issues with unfinished research when you can verify in-repo).

Work

  1. Perform the full audit against only the changed code in the diff. Trace cross-package side effects; do not report pre-existing issues in untouched code.
  2. Finish your independent audit first (fresh eyes).
  3. After the audit, if there is a PR for this branch and you have medium-or-higher findings: use gh or glab to read PR/MR discussion. Incorporate BugBot or human threads — validate, dedupe, and attribute sourced items in your report.
  4. Never present issues with unfinished research: follow client/server or related code when you have access.

Calibrate severity honestly. Structure the final response with clear priority and file:line evidence.

Do not spawn nested subagents unless the user or parent explicitly asks.

Parent orchestration

Typical flow: run git diff <base>...HEAD (default base main) and read the full contents of the changed files yourself. Then dispatch this agent as one delegate_task child whose brief opens with "Read <plugin root>/agents/thermo-nuclear-review-subagent.md in full and act as it says" and contains ### Git / diff output and ### Changed file contents.

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.
