v1.53: Agent Skills

|2 min read

What's New

  • Agent Skills: Install reusable skills from GitHub, folders, or Fabric's built-in collection. Browse the marketplace, activate skills with /<skill-name>, and safely uninstall with automatic conflict handling.

  • Fabric XLarge (Kimi K2.6): Now the default model for LARGE tier subscribers and pay-per-use fallback, offering better performance for complex tasks.

  • Parallel Background Agents: Built-in commands like /code-review, /research, and /review now run multiple agents concurrently in the background for faster results.

  • Smarter Chat Status: Tab icons now show what's happening at a glance — amber when waiting for your input, grey shimmer while generating, red on errors, and green when a response finishes in the background.


Performance

  • Faster Long Conversations: Major UI improvements keep chats smooth during streaming, even with hundreds of messages. Scrolling stays responsive and follows new text as it appears.

  • Reduced Token Usage: System prompts now use ~7,000 fewer tokens for common tasks like generating titles and summaries.


Bug Fixes

  • Fixed multi-window file opening — files now open in the correct window instead of showing "outside project" errors.

  • Fixed split-pane token counters — each pane now shows its own count instead of sharing the focused pane's number.

  • Fixed file search crashes on Windows WSL paths.

  • Fixed git worktree projects reopening to the wrong location on restart.

  • Fixed long conversations hiding the assistant's final answer inside collapsed sections.

  • Fixed conversation history preservation — Fabric now keeps more of your chat before summarizing older messages.

  • Fixed new tabs stealing focus across split panes — they now open in the correct pane.

  • Fixed voice input getting stuck in "processing" state.

  • Fixed rate-limit warnings disappearing too early.
