## Description

Improve factual reliability while creating or reviewing a course or supplied content. Use when the user asks to fact-check, verify accuracy, reduce hallucinations, make a reliable course, or mentions 事实性错误、知识性错误、专业知识准确性、可靠性. During creation, checks the completed pages before delivery; on existing content, returns a short evidence-backed report and lets the user choose what to fix. Not for grammar, style, or layout. Combine with deep-research when current evidence is the course's main subject.

# Fact check

Keep serious factual mistakes and AI hallucinations out of the course without
turning course-making into an exhaustive audit. Focus on the few claims that
materially affect trust.

Choose the mode from the request and current course state; do not ask the user
to choose a mode:

- **Creating:** when there is no course yet or the user asks to build/rebuild
  one, load `stage-design` and run the check only after all pages exist.
- **Reviewing:** when content already exists and the user asks to inspect it,
  report findings first. Do not edit unless fixes were already requested or the
  user approves findings after the report.

## While creating a course

Use the normal `stage-design` workflow; this skill changes factual handling,
not the teaching method, page style, or build sequence.

After all pages exist, call `list_scenes`, then read every completed page with
`read_stage` using `detail:"text"`; follow `nextOffset` until all visible text
and narration have been read. Run a quick final sanity check of exact facts and
cross-page contradictions. Correct obvious errors before delivery because
creating the course already authorizes making its content accurate, subject to
the source-of-truth boundary below. Do not interrupt creation with a separate
audit report or approval gate unless that boundary requires a user decision;
briefly mention only material corrections or remaining uncertainty when
handing off the finished course.

## When reviewing existing content

For a course, call `list_scenes`, then read all visible text and narration with
`read_stage` using `detail:"text"`; follow `nextOffset` until complete. Respect a
narrower scope if the user gave one.

Read once for context and silently shortlist high-signal risks:
