When the SDK marks the "default" model entry with a `resolvedModel`, `buildConfigOptions` now fills the option's `description` with the human-readable name of the matching named model (e.g. "Claude Sonnet 5") so clients can display it instead of a bare "Default". Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The SDK's session summary is set to the last user message after each turn, so editor tabs always showed the raw prompt text instead of a meaningful label. This change: - Calls claude-haiku after the first turn to generate a concise 3–6 word title from the first user message (IDE context block stripped) - Prefers the generated title over the SDK summary in session_info_update (user /rename still wins) - Eager-pushes the title in loadSession before history replay, so tabs update immediately on open instead of waiting for inventory refresh - Skips title generation silently when ANTHROPIC_API_KEY is absent (Bedrock/Vertex/gateway setups fall back to existing behaviour)

Problem
The Claude Code SDK sets
session.summaryto the last user message after each turn. As a result, editor tabs in AIR always showed raw prompt text (e.g. "продолжи", "смотри plugins/air...") instead of a meaningful title.Two separate issues contributed:
session_info_updatewas forwarding the SDK summary (last user message) rather than a semantic label.loadSessiondid not callmaybeUpdateSessionTitle, so the correct title only arrived after the next inventory refresh (up to 60s later).Changes
