This release adds Claude Fable 5 support, a dedicated model for session-title generation, and checksum verification for tool installs, along with session compaction and TUI fixes.

What's New

  • Adds title_model field for delegating session-title generation to a dedicated model
  • Adds Claude Fable 5 support with refusal handling and server-side fallbacks via provider_opts
  • Surfaces model refusals as a distinct finish reason
  • Adds asset checksum verification to tool installation and supports aqua version_overrides

Improvements

  • Allows models.dev in the sandbox proxy for model catalog metadata resolution
  • Makes the TUI editor component embeddable by other modules, with a new editor.WithPlaceholder option
  • Shows a toast error when opening a URL fails
  • Removes MCP catalog entries with broken OAuth

Bug Fixes

  • Fixes agent losing context and halting after the first session compaction by scaling compaction budgets to the context window
  • Fixes sub-session tokens being counted in the compaction trigger
  • Fixes Anthropic parallel tool calls by routing input_json deltas by content-block index
  • Adds a max_tokens floor for Anthropic when thinking is disabled
  • Fixes sidebar token usage panel flickering during sub-agent transfers
  • Surfaces useful errors when session title generation fails and honors the agent title_model in the debug title command
  • Fixes fork-mode skill commands looping in the TUI
  • Fixes cell alignment when the suggestion overlay cuts a wide rune
  • Fixes the configured placeholder not being restored when voice recording stops

Technical Changes

  • Disables git commit signing in test helpers
  • Bumps github.com/anthropics/anthropic-sdk-go to v1.49.0
