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.

Claude Code v2.1.242

Subagents inherit the session model, and delegated reports are asked for as HTML

You'll notice

Subagents

Subagents now run on your session's model, and delegated reports are asked for as HTML pages.

What

The instructions Claude follows when handing work to a subagent now say to leave the model unset so the worker runs on the same model as your session, and never to move substantive work to a cheaper one. Where the page-publishing tool is available, delegated reports are asked for as .html pages instead of a Markdown file.

Details
  • the HTML paragraph is appended only when the publish tool is in the delegating agent's tool list; otherwise the prompt is unchanged
Evidence

Omit the model parameter so workers inherit the session model

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
