Summary

AI summary

Auth is no longer required in the critical path; device code authentication enables optional Studio activation.

Full changelog

The big change

Auth is no longer in the critical path. Extraction, preview, brand_check, and all local tools work without authentication. The first 10 minutes are zero-friction. Studio activation is the optional upgrade.

Added

Device code authentication. brand_brandcode_auth mode="activate" displays a short code (e.g. BRAND-7K4X) for the user to enter at brandcode.studio/activate. The agent polls for completion. No JWT copy-paste. No leaving the session to hunt for tokens. Two tool calls, fully agent-driven.

Changed

Auth deferred from happy path. Tool descriptions, prompts, recovery guidance, and status messages stop pushing Studio auth until the brand is extracted and the user wants persistence.
brand_brandcode_auth now leads with activate mode and explicitly states auth is NOT needed for extraction or checking.

39 tools. 4 prompts. 2 resources. 395 tests.

Breaking Changes

Removed requirement for authentication in the critical path of extraction, preview, brand_check, and all local tools.
