release aidev SIG 4/5

Default model env var, cross-session idle notification, auto mode improvements, screen reader support

Adds ANTHROPIC_DEFAULT_MODEL to set the starting model for new sessions while /model overrides persist across restarts. Adds notify_when_idle to SendMessage for one-shot cross-session coordination. Sandbox wildcard read-deny rules now correctly take precedence inside allowed regions. Auto mode gains severity-scored classification on all supported backends and a hardened git status check. VS Code gets screen reader support for the transcript. The /model picker trims to fit the terminal height. SIGTERM in print/SDK mode exits cleanly. Dozens of bug fixes across fullscreen rendering, session recovery, SendMessage, and more.

SOURCES1
  • Added ANTHROPIC_DEFAULT_MODEL env var (sets new session default; /model overrides persist across restarts)
  • Added notify_when_idle to cross-session SendMessage (opt-in, one-shot, no polling; macOS and Linux)
  • Sandbox wildcard read-deny rules now take precedence inside allowed read regions on macOS
  • Fixed clipboard copy, background housekeeping, background sessions, and local MCP logs breaking when session cwd is removed (regression in 2.1.229)
  • Fullscreen renderer falls back to classic instead of failing permanently after a single failed start
  • /model picker now shows only as many models as fit the terminal, with scroll for the rest
  • Fixed SendMessage being rejected when a malformed closing tag left text inside the summary field
  • Fixed unhandled promise rejections when a subprocess fails to start (powershell.exe on WSL; regression in 2.1.234)
  • Fixed fullscreen mode not showing newly sent messages until the next resize
  • Fixed blank band above prompt after clearing multi-line input in fullscreen mode
  • Managed-settings approval prompt now reliably appears at startup
  • Fixed terminal tab titles jumping in tmux (iTerm integration)
  • Fixed unclear error when cloud environments list is empty or malformed
  • Fable 5 first-time usage-credits prompt no longer auto-selects fallback model after 60s silence
  • Fixed spinner tips never appearing with malformed guest-pass cache
  • Fixed skills hot-reload raising errors after session cwd is deleted (2.1.229+)
  • Fixed self-hosted runner sessions occasionally resuming before post-session hook finishes
  • Fixed Clawd mascot rendering unevenly in iTerm2 at some font sizes
  • Session recap text capped at 400 characters (cut at word boundary)
  • Session counter now written in background (startup performance)
  • Auto mode: Monitor allow rules set aside while auto mode is active
  • Auto mode: same defaults (severity-scored classification) on Bedrock, Vertex AI, Foundry, and when telemetry is disabled
  • Auto mode: git status check no longer fooled by status.showUntrackedFiles=no
  • /model picker highlights only the newest model's name
  • /goal: idle sessions with long-running background work auto check in after 30m (then 1h, 2h)
  • /usage now shows usage-credits spend row for Team/Enterprise members
  • SIGTERM in print/SDK mode exits cleanly without recording interrupted turns or synthetic tool denials
  • Slash-command typos now report the error instead of running the closest fuzzy match (prefixes and aliases still work)
  • Remote Control marks session offline within seconds when CLI exits or terminal closes
  • SendMessage refuses rapid bursts to a session that would exceed its inbox capacity
  • Session title chip aligned with footer right edge
  • Right-aligned footer items now share consistent right margin
  • [VSCode] Added screen reader support: live announcements for replies, permission requests, errors, status changes, plus per-turn heading navigation
