cold-review

cold-review is a skill for Claude Code from allemaar/open-skills. It costs 107 tokens per session (2,212 once invoked), scanned A, original, Apache-2.0.

An independent review process for checking real work such as code, tests, documents, screenshots, plans, and command results against its goals. It uses fresh reviewers and evidence to find issues the original worker may have missed.

In plain words
What is it for?
Use it to review completed or unfinished implementation work, compare results with objectives, classify problems, and apply review scores or pass thresholds.
Why use it?
It reduces the risk of approving work based on familiarity or personal bias. Findings are checked again before the review is returned.

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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/cold-review

Run an independent review of actual work artifacts using fresh context. The goal is to surface issues the current agent misses because it has too much context, owns the work, or is biased toward its own implementation. This is a workflow, not a persistent mode.

Structured execution spec: protocol.yon. Read it for the canonical rules and step sequence; this file is explanation. The two must stay in sync — if you edit one, update the other and refresh the @STAMP date.

Caller Options. Before executing, run the Caller Options protocol (caller-options/SKILL.md): triage this invocation for material optionality across the venues and modes declared in front-matter; if one path clearly dominates, proceed silently; otherwise surface the options to the caller. cold-review's modes are the reviewer-count tiers (narrow/medium/broad → 1/2/3 reviewers); its venue is inline only (cold-review spawns its own reviewers — COP never wraps a self-orchestrating skill).

Boundary

Use cold-review for completed or in-progress work artifacts: diffs, files, code, tests, screenshots, UI states, plans, specs, docs, command outputs, worker reports. Do not use it for raw ideas. Use insight-adversarial for multi-POV critique of plans/ideas/strategy, verify for a formal self-gate, and double-check when the current agent should re-read and challenge a specific target itself.

Step 1 — Establish target and objectives

Identify: the work assessed; the objectives (infer and label as inferred if not given); the constraints (non-goals, compatibility, style, acceptance criteria, preferences); and the available evidence (tests, commands, screenshots, docs, diffs, source). If no concrete artifact exists, stop and ask for the target — do not review from vague memory.

Step 2 — Classify the work

Classify the primary target type and choose lenses accordingly:

Target type Required review lenses
Backend / code Correctness, architecture, security, tests, maintainability, performance
Frontend / UI User flow, visual layout, responsiveness, accessibility, interaction states
Plan / spec Ambiguity, scope, sequencing, assumptions, executability
Agent skill / workflow Trigger clarity, runtime portability, step ordering, failure modes
Mixed work Pick the top 2 target types and cover both

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.
