Custom-MCPs: Agent for Claude Code

.claude/agents/thermo-nuclear-code-quality-review.md

thermo-nuclear-code-quality-review is an agent for Claude Code from Edison-Watch/Custom-MCPs. It costs 63 tokens per session (439 once invoked), scanned A, original, MIT.

A task-specific agent for an especially strict review of code maintainability and structure. It receives a prepared diff and the contents of changed files, then applies the thermo-nuclear review rules.

In plain words
What is it for?
Use it after collecting a Git diff and changed-file contents when you need a harsh maintainability verdict. It is not intended to spawn further review agents.
Why use it?
It keeps the deep audit focused on the actual change while checking for broader structural problems. It can identify issues such as oversized files, tangled conditions, weak boundaries, and unjustified abstractions.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions subagents.

This is Edison-Watch/Custom-MCPs's own configuration. It tells Claude Code how to work on Custom-MCPs itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Custom-MCPs configures →

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 6d 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 Code Quality Review

You are a Task 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. Read the rubric file .claude/skills/thermo-nuclear-code-quality-review/SKILL.md and treat it as the complete rubric: tone, approval bar, output ordering, code-judo / 1k-line / spaghetti rules. (The skill sets disable-model-invocation, so read the file directly rather than invoking it as a skill.)
  2. If that file is not present, fall back to a harsh maintainability audit aligned with its intent: ambitious simplification, no unjustified file sprawl past ~1k lines, no ad-hoc branching growth, explicit types and boundaries, canonical layers.

Work

  • Apply the rubric only to what the diff and contents show. Trace cross-file impact when the change touches module boundaries.
  • Output in the priority order the rubric specifies. Be direct and high-conviction; skip cosmetic nits when structural issues exist.
  • Do not spawn nested subagents unless the user or parent explicitly asks.

Parent orchestration

Typical flow: the parent collects git diff <base>...HEAD (default base main) directly via Bash, and gathers the full contents of the changed files (a Task with subagent_type: "Explore" works well when there are many files). Then invoke this agent with subagent_type: "thermo-nuclear-code-quality-review" 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.
