spawning-reviewers

spawning-reviewers is a skill for Claude Code from smixs/disruptor-skills. It costs 102 tokens per session (3,643 once invoked), scanned A, original, MIT.

A method for assigning independent reviewer agents to examine a fixed piece of work and return specific, ranked findings. The work can be code, a design, a document, a plan, or research.

In plain words
What is it for?
Setting up adversarial reviews, choosing reviewers from different perspectives, and requiring findings to point to exact locations in the artifact.
Why use it?
It reduces the risk of reviews simply agreeing with the original description or repeating the same reviewer’s assumptions.

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

spawning-reviewers 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.

Spawning Reviewers

Stage contract

  • Stage: 5a. Review (inside the build loop) · Kind: method
  • Inputs: a settled artifact to critique (frozen — no edits while the review runs).
  • Outputs: ranked findings anchored to precise locations — no verdict.
  • Entry gate: called each review-and-fix iteration by the converging-and-polishing skill.
  • Done when: located findings returned from a cross-family / independent critic (unanchored claims don't count).
  • Next: back to the converging-and-polishing skill — you fix the real findings, verify, re-spawn.

Overview

A review's value is decided before the reviewer starts working — by how you framed the prompt, which reviewers you picked, and whether you forced them to examine the real thing. Get those wrong and even a strong model returns confident noise.

Core principle: a reviewer is an instrument you can bias or starve without noticing. Tell it what you expect — or even where to look — and it confirms your priors. Don't make it look at the artifact and it reviews your description of the artifact. Pick reviewers that share a brain and their agreement means nothing. This skill is the discipline that prevents all three.

When to use

  • You want a genuine critique, not reassurance, on anything that "works but might be wrong/bloated/fragile."
  • A high-stakes or hard-to-reverse decision deserves an independent perspective.
  • A previous review felt thin, agreeable, or suspiciously aligned with what you already believed.

When NOT to use: trivial or throwaway artifacts; when you need help producing rather than critiquing; when a 30-second self-check settles it.

The two failure modes (the heart of the skill)

1. Leading the witness — biased framing

Anything in the prompt that signals what you expect or where to look gets echoed back. Poison includes:

  • a changelog / history ("here's what changed", "after N rounds of fixes")
  • a list of suspected problems or "I think X is the issue"
  • pointing at a region — or assigning a sub-area to "focus on / go deepest on". Even a neutral-sounding "go deep on the auth module" partitions the artifact and caps what the reviewer hunts for. Coverage is not a reason to pinpoint (see Principle 3 for the real fix).
  • enumerating the artifact's parts. A feature/module list in the prompt reads as an exhaustive set — the model treats it as the whole and stops thinking past it. Point at the artifact; do not list it.
  • calibrating the outcome ("should be clean", "few findings expected")
  • asking for a pass/fail verdict instead of findings

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.

spawning-reviewers is a skill published in the GitHub repository smixs/disruptor-skills (18 stars, last pushed 2mo ago), licensed MIT. It adds 102 tokens to every session and 3,643 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 2026-08-30.
