ai-output-verifier

ai-output-verifier is a skill for Claude Code from mohitagw15856/pm-claude-skills. It costs 142 tokens per session (1,119 once invoked), scanned A, original, MIT.

A skill for checking whether an AI answer is accurate before relying on it. It identifies claims that may be wrong or invented and suggests ways to verify them.

In plain words
What is it for?
Use it to review a specific answer, decide which claims need independent checking, choose verification sources or tests, and spot signs of fabricated information.
Why use it?
AI can state false facts, citations, numbers, or recent details with confidence, making unverified answers risky to use.

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

ai-output-verifier 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 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.

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.

AI-Output Verifier

AI is fluent, confident, and sometimes completely wrong — inventing facts, citations, and details in the same authoritative tone as the correct ones. That confidence is exactly what makes unverified trust dangerous. This checks a specific output: which claims are most likely wrong or fabricated, what genuinely needs independent verification, how to verify it, and the tells of hallucination — so you use AI's speed without inheriting its errors.

What This Skill Produces

  • A risk read of the output — which specific claims are most likely to be wrong, outdated, or made up (facts, numbers, citations, names, recent events, specifics)
  • Verify vs. low-risk split — what genuinely needs independent checking vs. what's low-stakes or self-evident, so you spend effort where it counts
  • How to verify each — the concrete way to check the high-risk claims (a primary source, a second tool, a domain expert, testing it)
  • The hallucination tells — the signs AI is likely fabricating (oddly specific citations, confident claims about recent/niche facts, plausible-but-unverifiable details)
  • A verification habit — how to build appropriate checking into your AI use by default, scaled to the stakes (trust more for low-stakes, verify hard for high-stakes)

Required Inputs

Ask for these if not provided:

  • The output — the AI response to check (paste it)
  • What it's for — the stakes (a casual question vs. something you'll publish, decide on, or act on)
  • The domain — factual/technical/legal/medical/current-events (some are far higher-risk for AI)
  • What you'd do with it — trust it, act on it, share it, build on it

Framework: Risk-Rate The Claims, Verify What Matters

  1. Scan for the high-risk claim types. Specific facts, numbers, dates, names, citations, recent events, and niche/technical specifics are where AI most often invents — flag these.
  2. Split by risk and stakes. Separate the claims that genuinely need verification (high-risk × high-stakes) from the low-risk or low-stakes ones you can reasonably accept — don't verify everything equally.
  3. Verify against real sources. For the high-risk claims, check a primary source, a second independent tool, an expert, or by testing — not by asking the same AI "are you sure?" (it'll often just re-confirm).
  4. Watch the hallucination tells. Oddly precise citations, confident answers about very recent or obscure things, and unverifiable specifics are red flags — treat them as unverified until checked.
  5. Scale trust to stakes. For low-stakes uses, light verification is fine; for anything you'll publish, decide on, or that could harm if wrong, verify hard. Build this reflex in.
