The story this week is upstream churn breaking quiet assumptions in the AI layer, and fixes focused on preserving what providers actually send.

First, reasoning signatures. In pull request ten one hundred, Claude through OpenRouter can stream a signature separately from any thinking text. The old validation required text to be present, so those signature-only updates were dropped. That mattered after a tool call, when the thinking block was replayed without…

Related is model catalog drift, seen in commit six F seven five five one five. The shared model catalog removed the Kimi K two point six, G L M five point two, and dated DeepSeek version four entries on Fireworks, which broke type checks against the regenerated list. Tests and the default were updated. For…

Second, shell context. In pull request ten one thirteen, bash and PowerShell results keep only the tail — roughly two thousand lines or fifty kilobytes — with the rest spilled to a temp file the model never sees. When the optional Supercompress key is set, a truncated result under the size limit is sent once to the…
