review

review is a skill for Claude Code from kimmingul/xllm. It costs 102 tokens per session (838 once invoked), scanned A, original, MIT.

A tool for asking several external AI systems to examine the same question or code change, then combining or comparing their responses. Its modes support parallel advice, independent blind answers, adversarial debate, or a combination of blind review and debate.

In plain words
What is it for?
Use it for design decisions, code-diff reviews, security checks, competing opinions, measured agreement, or arguments that need to be challenged.
Why use it?
It gives you more than one perspective and can expose disagreement or weaknesses that a single review might miss.

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

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 8d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

review — cross-vendor deliberation (xllm)

One entry point, four modes. Your host CLI synthesizes; external CLIs advise.

Resolve the script

Claude Code: "${CLAUDE_PLUGIN_ROOT}/scripts/xllm-review.js". Other hosts: <plugin-root>/scripts/xllm-review.js (two dirs above this SKILL.md).

Modes

node <xllm-review.js> roles   p1,p2[,p3] "<prompt>"      # parallel advisors, host synthesis — NOT measured
node <xllm-review.js> blind   p1,p2[,p3] "<question>" [--tiebreak] [--ready=a,b,c]
node <xllm-review.js> debate  p1,p2[,p3] "<claim>"       # SURVIVED / KILLED / UNRESOLVED
node <xllm-review.js> council p1,p2[,p3] "<question>" [--tiebreak] [--ready=a,b,c]
node <xllm-review.js> stats                              # pairwise agreement (measured decorrelation)
node <xllm-review.js> outcome <run-id> --adopted <spec|majority|minority|none> --helpful yes|no
mode epistemology cost reach for it when
roles coverage — synthesis labels, not measured advisors need different prompts
blind measurement — identical blind prompt, append-only ledger ~1× you want the measured spread
debate adversarial — decisive falsifiers kill wrong claims ~2–3× being wrong is expensive
council independent divergence → hostile convergence ~3–4× the highest-stakes calls

Reviewing code

Add exactly one diff source to any mode. The diff is collected deterministically (plain git), size-capped, sent to advisors — and never persisted (ledger/index record source/stat/bytes only):

--staged | --base <ref> | --diff-file <path>

--base <ref> is two-dot (git diff <ref>): working tree vs ref, so uncommitted changes are included — NOT a merge-base (three-dot) branch diff.

Contract

  • Advisors are read-only; your own vendor is refused; nothing is auto-applied.
  • blind/council write <state>/panel-ledger.jsonl BEFORE prose. The ledger is truth; your summary is UX; minority reports are findings; failures abstain.
  • roles output is never "measured" — its labels are your synthesis, not agreement rates. Only blind/council/stats speak measured decorrelation.
  • On a blind split the core suggests the measured tiebreaker for free — spend it with --tiebreak; never hand-pick by vendor pedigree.
  • Afterwards record adoption: outcome <run-id> … — it feeds measured routing.
  • SURVIVED = withstood refutation, not proven. Re-verify consequential claims.

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.

review is a skill published in the GitHub repository kimmingul/xllm (2 stars, last pushed 15d ago), licensed MIT. It adds 102 tokens to every session and 838 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
