Remote script. The skills.sh installer copies skills from this GitHub repo, so review the repo before running it on a machine you care about.

Who it is forA busy reader or viewer who needs the gist of a 27-minute video or long article, or the meaning of one confusing moment, without watching the whole thing.

The problemAgents cannot watch videos, and YouTube's official API will not give captions for videos you do not own, so the content has to be fetched as text first.

The outcomeA plain-language summary of the link, or an explanation of the part you name, built from the fetched transcript or text.

What you need first

  • uv installed (the fetch script uses it to resolve its dependencies)
  • An agent with web search and the ability to run scripts, such as Claude Code, Codex, Cursor, or Gemini CLI
  • A YouTube, TikTok, article, tweet, or PDF link, or pasted text

Steps

  1. Install uv from https://docs.astral.sh/uv/ if you don't have it.
  2. npx skills@latest add SerhiiKorniienko/bullshit-detector
  3. Open your agent and ask: summarize <URL>
  4. Or ask: explain the part at 12:30 in <URL>
  5. If a site blocks fetching, paste the text or transcript and ask again.

Prompt for your agent

Using the fetch-content skill in SerhiiKorniienko/bullshit-detector, fetch <URL> and summarize it in plain language. If I name a timestamp, explain that part. Verify that the summary reflects the fetched text and says so if captions or text were unavailable.

Caveat. Fetching depends on what each site exposes, and the tool reports an actionable hint such as paste the text when a paywall or missing captions blocks it.
