Release notes

Local Hoist v0.4.3

September 2, 2026

Adds Claude Fable 5.1 and new thinking controls for Claude models, retires the think and view_summaries tools, and fixes stuck shell tools and Linear MCP updates.

New

  • Added Claude Fable 5.1, Anthropic's frontier model for difficult coding and long-running agent work, with a 1M-token context window, 128k output, and always-on adaptive thinking.
  • Added per-conversation thinking controls for Claude models. Choose whether thinking is summarized, hidden, or shown as live progress updates while Claude works.
  • Added a thinking block setting for Claude models that mirrors Anthropic's API. Grandfathered API keys can keep the Legacy behavior; newer keys must choose Error or Drop. Legacy preserves the most thinking, so use it where your key allows. See Anthropic's notes on editing earlier turns.

Improved

  • Codex OAuth requests now send a routing hint for the requested model and Fast tier. Codex may still downgrade Fast to standard under load and reports the tier it actually served.
  • Compact tool call rows now align their chevrons with the label, and diff views no longer show duplicate plus signs or clipped backgrounds when scrolling horizontally.
  • Tool descriptions are clearer about when to use view_media, which helps models avoid redundant calls for images already visible in the conversation.

Fixed

  • Shell tools no longer appear stuck in a running state after an early parameter error, and terminal commands now show the same copy and action controls as regular shell calls.
  • Linear MCP update tools now send conditional arguments correctly, so patching issues, projects, and comments works. Cached MCP specs are re-sanitized on startup so the fix applies without clearing the cache.
  • Opening files in VS Code now falls back to the configured working directory when the workspace snapshot is empty.

Deprecated

  • Removed the think tool. Every model we recommend now has thinking built in, and some providers treat a separate thinking tool as an attempt to extract raw reasoning traces and may block the response.
  • Removed the view_summaries tool. Use a local research sub-agent for the same kind of codebase overview.
