thermo-nuclear-review-subagent

thermo-nuclear-review-subagent is an agent for Claude Code from michael-denyer/pstack-claude. It costs 65 tokens per session (498 once invoked), scanned A, original, MIT.

A branch-review helper that checks changed code for bugs, breaking changes, security problems, developer-workflow regressions, and accidental feature exposure. It reviews only code added or modified in the change.

In plain words
What is it for?
Use it for a thorough security and correctness audit of a branch or pull request before merging.
Why use it?
It helps catch risks that may appear when a small code change affects other modules or packages. It can also take existing pull-request discussion into account when relevant.

About the project

pstack-claude is a set of opinionated coding-agent skills and workflows ported from Cursor to Claude Code, Codex, Pi, and other agent harnesses. It guides agents toward concise, simple, and verified code by routing goals to suitable workflows and supporting subagent tools. The catalogue entries are the project's skills, agents, hook, and plugin implementations for these agent environments.

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 3d 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

Thermo Nuclear Review (Deep review)

You are an Agent subagent. 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 review-bot 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, through the Explore agent when the set is large. Then invoke this agent with subagent_type: "pstack:thermo-nuclear-review-subagent" and a user prompt containing ### 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.
