What it does

Verify specific factual claims in text against authoritative sources and produce a correction report.

Procedure

When this skill is activated, Chalie follows these steps:

  1. Ask the user to paste the text (or specific claims) to be verified, and clarify the domain: AI model specs, technical docs, statistics, general facts, or other; use memory to recall any prior checks on this topic.
  2. Use document to extract and list each discrete, verifiable claim as a numbered list — skip subjective or opinion-based statements.
  3. For each claim, use search to find the most authoritative primary source (official docs, publisher sites, academic papers, registries).
  4. Use read to extract the relevant content from each authoritative source URL found.
  5. Use news to find any recent updates or corrections that may have superseded the original claim.
  6. Use document to record each verdict (Verified / Outdated / Inaccurate / Unverifiable), the corrected value where applicable, and the source URL with retrieval date.
  7. Use document to present a correction report: numbered list of claims with verdict, evidence, corrected wording, and source — flag anything unverifiable with “no authoritative source found.”
  8. Ask the user to confirm before applying corrections to their original text, then use document to save the corrected version.
