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.

Background Agents

Background session names auto-changed to dodge collisions now survive respawn like ones you chose.

--name-n
What

A background session's name now records a third origin, collision, alongside user-chosen and derived. Names given for this reason are treated like user-chosen ones when a session respawns, so the --name/-n flag is preserved rather than dropped, and the session list displays them differently.

Evidence

nameSource === "collision"

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