Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Web Fetch not in their notes

Web fetching is capped at 15 turns and runs in the foreground unless you background it.

What

The built-in web-fetching helper is now bounded to 15 turns, where its configuration previously set no cap. Its instructions were also reframed: it runs in the foreground and returns its report as the tool result, and backgrounding is now the exception you opt into with run_in_background: true when you have independent work to do meanwhile.

Details
  • Live for everyone using the web-fetch tool; no gate.
