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.

How eagerly Claude is told to run shell commands now varies with the session's proactive level.

What

The Bash tool's instructions are now built with the session's proactive level as an input, so how eagerly Claude is told to run shell commands can differ between sessions.

Evidence

async prompt({ model: e, tools: t, proactiveLevelActive: r })

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