What it does

This skill teaches an AI agent to review a set of knowledge pages (a 'brain' of notes) and check that every fact carries an inline source citation in a standard format, with a date and source type. Where a citation is malformed, the agent rewrites it to match the standard; where a post or tweet is mentioned without a link, the agent tries to find the original through the host's X/Twitter API integration and adds a verified x.com link. It then reports counts of pages scanned, issues fixed and remaining gaps.

Great for

  • Maintainers of a gbrain-style knowledge base who want consistent source citations
  • Researchers or writers who reference social media posts and need verifiable links
  • Teams running a periodic batch cleanup of citation quality across many pages

Skip it if

  • Users who want the agent to invent or fill in missing sources: the skill says to flag unsourced facts, not guess them, and guessing would create false citations
  • Single documents outside a brain-page system, since the conventions and page tools it relies on are specific to gbrain
  • Bulk edits run without review: the skill itself recommends checking a sample first, because it rewrites pages and cannot be trusted to get every fix right

Try asking

  • “Fix citations on this page”
  • “Run a citation audit across my brain pages and report the gaps”
  • “Resolve the broken tweet references on the pages I edited this week”
  • “Check citations on the pages that mention posts from X but have no links”

Get better results

  • Run on a small sample of pages first and review the rewritten citations before any batch run, as the skill advises.
  • Check that the X API credentials and rate limits are set up by your host before starting, since tweet resolution depends on them.
  • Keep a backup or version history of the brain pages, because the skill rewrites pages (marked mutating: true) and resolves conflicts by re-reading them.
