verify-claims

verify-claims is a skill for Claude Code, Codex from jstoup111/ai-conductor. It costs 58 tokens per session (1,956 once invoked), scanned A, original, Apache-2.0.

A checking step for important factual claims and assumptions that will influence a plan, specification, architecture decision record (ADR), finding, or code decision.

In plain words
What is it for?
Use it before relying on a nontrivial claim to record confidence, explain its basis, and require approval for assumptions that could change the work.
Why use it?
It exposes uncertain foundations before they lead to expensive downstream mistakes.

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

verify-claims 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 10d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Decisive skills routinely state things as fact, or spec and build on assumptions, without ever marking them as uncertain or getting them confirmed. A wrong assumption that slips into a PRD, an ADR, a plan, or code is discovered late and is expensive to unwind.

This skill is the correctness discipline other skills apply at their decision points. It does two things:

  1. Calibrates claims. Non-trivial statements and theories carry a grounded confidence estimate (a %) with the basis for it. No confident-sounding prose hiding an unverified guess.
  2. Gates assumptions. Every assumption is surfaced explicitly. Any assumption that is load-bearing — one that, if wrong, changes what gets specced or built — is a hard block: the work does not proceed on it until the operator explicitly approves it.

It is deliberately cheap and quiet on high-certainty, low-stakes output, and loud exactly where a mistake would cascade. It does not replace domain review, conflict-check, or prd-audit — it sits before them, keeping unverified foundations out of the artifacts they inspect.

When This Applies

Apply the protocol whenever output is load-bearing — it will drive downstream work:

  • A PRD functional requirement, an approach recommendation, or a track decision (explore, prd)
  • An architectural claim or ADR (architecture-review)
  • A story's acceptance criteria or a plan task (stories, plan)
  • A statement about how existing code, an API, a schema, or a dependency behaves, when that statement decides what to build (tdd, debugging, manual-test)
  • Any answer to the operator that they may act on as fact

Skip it for casual conversation, restating something the operator just said, or trivially verifiable mechanics with no downstream blast radius. Ceremony on low-stakes output is noise — correctness matters at the load-bearing points, not everywhere.

Practices

1. Separate Claims From Assumptions

For the output under review, split its load-bearing content into two buckets:

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.

verify-claims is a skill published in the GitHub repository jstoup111/ai-conductor (7 stars, last pushed today), licensed Apache-2.0. It adds 58 tokens to every session and 1,956 once invoked, about $0.0003 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.
