Cotal: Skill for Claude Code

.claude/skills/cold-review/SKILL.md

cold-review is a skill for Claude Code from Cotal-AI/Cotal. It costs 119 tokens per session (3,777 once invoked), scanned A, original, Apache-2.0.

A procedure for preparing a brief for an independent reviewer who has not seen a review panel's findings. The reviewer acts as a separate check on a code change or other work.

In plain words
What is it for?
Define what an independent reviewer receives, what its verdict covers, and who can override it while grading a change separately from the existing review panel.
Why use it?
Review panels can agree on the same mistake because their members share the same context. Keeping the cold reviewer isolated can expose defects that the panel missed.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

cold-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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cold review

A cold reviewer is not an extra panelist. It is a control on the panel.

A panel converges. Reviewers read each other, findings get confirmed by seats already looking in the same direction, and the group arrives somewhere with more confidence than any member earned alone. That convergence is usually right, which is why it is dangerous when it is wrong: a panel of three has approved a head carrying a defect all three missed, and what surfaced it was a differently framed read, not a fourth verifier.

This file is read by the person who WRITES the brief, not by the seat being briefed. The value is in the brief, not in the seat's context. A cold seat that never loaded a skill file, never joined the mesh and received nothing but a persona has produced three blockers that two fully-briefed lenses missed. So nothing here requires the graded seat to have access to this document, and no rule below may be written so that it does.

The isolation

  • Never joins the review channel. Not muted, not quiet. Not joined.
  • Never shown the panel's findings, verdict, or round count, including as a list of things already ruled out so it can skip them. Skipping-instructions are findings shaped like scope.
  • DM-only or file-only input from the author or manager. Its verdict goes first-hand to the dedicated record destination itself.
  • Never shares a model family with whoever WROTE the change.

Why never join, stated correctly. Joining exposes the seat to the panel's live traffic for as long as it is subscribed, and the panel is active during a cold read. Replay of history is a second exposure path but not a guaranteed one: replay is channel.replay ?? defaults.replay ?? true, a default-true policy with a per-channel override, so a replay=false channel would not replay. The rule does not depend on that setting in either direction, and a brief that justifies it by replay alone is resting on a config it cannot rely on.

Prefer the ACL to the request. subscribe: [] plus an allowSubscribe that excludes the panel channel makes non-join a property of the seat rather than an instruction it must follow. Where a fence exists, use the fence.

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.
