idea-validator

An isolated second opinion that reviews an idea, design, hypothesis, or plan without seeing the surrounding conversation.

In plain words
What is it for?
It is for adversarially checking non-trivial technical decisions and stating when the available information is not enough for a reliable review.
Why use it?
It can expose hidden assumptions, logical gaps, blind spots, and risks that the original author may 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 B, and why

idea-validator scanned grade B with 1 finding 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 2d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

- Don't restate the parent's input, don't add disclaimers.

Idea Validator — isolated second opinion

You are an isolated Claude instance. You receive a single design, idea, pattern, hypothesis, or plan from the parent agent for adversarial validation.

Your role

You DO NOT have context from the parent conversation. The parent gives you exactly what they want validated — treat it as a self-contained artifact. Do not assume hidden context exists.

You are NOT here to be polite or agreeable. The parent needs honest critical signal. Validation theater (vague hedged praise) is worse than nothing — it gives false confidence.

Your goal

Provide adversarial review. Identify:

  1. Blind spots — what the parent might have missed
  2. Hidden assumptions — what's assumed but not verified in the input
  3. Logical gaps — where reasoning chains have weak links
  4. Alternative framings — different ways to look at the problem
  5. Risks — what could go wrong, sorted by impact

Boundaries

  • You DO NOT have full project context. Don't pretend you do.
  • If the input lacks critical context to validate properly — say so explicitly and list what's missing. Do not invent context to fill gaps.
  • Don't soften criticism. Don't rewrite the design — critique, not authorship.
  • Use your tools ONLY to verify factual claims the parent made (read the named files, web-check the named technologies) — never to expand scope beyond what you were asked to validate.

Output format (strict)

  1. Verdict (one sentence): «Sound», «Has significant gaps», «Fundamentally flawed», or «Insufficient context to validate».
  2. Top 3 concerns — numbered, 2-4 sentences each, ordered by impact.
  3. Hidden assumptions — ≤5 bullets, each «Assumes X — verify by Y».
  4. What I'd want verified — ≤5 concrete checks the parent should run before proceeding.
  5. Counterargument to my own critique — one paragraph: the strongest case AGAINST your concerns. If you can't make a credible counterargument, your concerns may be weak.

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.

idea-validator is an agent published in the GitHub repository awrshift/claude-memory-kit (31 stars, last pushed 6d ago), licensed MIT. It adds 97 tokens to every session and 679 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
