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.

Scripted sessions now get a stream-json status message whenever the permission mode changes.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

Read once, for one account on one subscription tier, against v2.1.234. It isn't a statement about your account. What a flag value here can and cannot tell you

--output-format stream-json
What

Programmatic sessions (SDK and --output-format stream-json) now get a message whenever the permission mode changes: {type:"system", subtype:"status", status:null, permissionMode, uuid, session_id}. The same status is re-sent when a remote client reconnects or attaches, so a client that joined late still knows the current mode. Controlled by tengu_wobbly_pinwheel, which falls back to true, so it is on unless remote config turns it off.

Details
  • The emission on mode change sits behind a flag helper; the reconnect/attach resend keeps late joiners in sync.
  • status is null on these messages; the mode itself is carried in permissionMode.
