Pro Plan Opus Default Option#

What: New experimental feature that allows Pro plan subscribers to use Opus 4.5 as their default model.

How it works: When enabled via the tengu_opus_default_pro_plan experiment, Pro plan users will see "Opus 4.5 · Most capable for complex work" as their default model option.

Details:

  • Controlled by experimental flag tengu_opus_default_pro_plan with variant opus_is_default
  • Added VI6() function at line 181554 that checks if the user's plan is "pro"
  • Added haA() function at line 181569 that checks if the Opus default experiment is enabled
  • Model description function uaA() at line 181634 now includes the Pro plan Opus option check

Teammate Message Display Component#

What: New UI component to render incoming teammate messages with proper formatting and color support.

How to use: Teammate messages are automatically displayed when received via the inbox system. Messages appear with the teammate's ID and optional color styling.

Details:

  • Added L69() component at line 471586 to parse and render <teammate-message> tags
  • Added KS7() parser function at line 471552 that extracts teammate ID, color, and content from message tags
  • Messages are rendered with teammate identification and styled borders
  • Evidence: Message rendering added at line 17992-17993 in the message display switch statement

Agent Notification Display Component#

What: New UI component to display agent completion/failure notifications in the conversation.

How to use: When a background agent completes or fails, a notification is automatically shown with the agent ID, status, and summary.

Details:

  • Added O69() component at line 471624 to render <agent-notification> tags
  • Displays agent ID, status (completed/failed/stopped), and summary message
  • Includes guidance to use AgentOutputTool to retrieve full results
  • Added function m39() at line 479132 to format and queue agent notifications
  • Evidence: Message rendering added at line 17994-17995 in the message display switch statement

Prompt Queue Auto-Execution Hook#

What: New hook that automatically processes queued commands when the session becomes idle.

How it works: When commands are queued (via /add-to-queue or similar), they are now automatically executed when the session is no longer busy, rather than requiring manual intervention.

Details:

  • Added i59() hook at line 475244 that monitors loading state and queued commands
  • Calls executeQueuedInput callback when session is idle and queue is non-empty
  • Added p59() function for executing the queued input with proper state management
  • Tracks execution with a ref to prevent duplicate processing
  • Evidence: Hook usage at line 19833-19839 in main component

Teammate Message Submission Handler#

What: New handler that allows submitting messages directly from the inbox to the conversation when idle.

How it works: Messages from teammates in the inbox can now be submitted as user queries when the session is idle, enabling seamless teammate collaboration.

Details:

  • Added w39() hook at line 478948 for inbox polling and message delivery
  • Added onSubmitTeammateMessage callback that creates a user message from teammate content
  • Includes sophisticated idle detection and busy-state queuing logic
  • Evidence: Hook usage at line 19883 in main component

Disable Slash Commands Option#

What: New disableSlashCommands parameter for the main component that prevents slash command processing.

How to use: Pass disableSlashCommands: true to the main component to disable all slash command handling.

Details:

  • Added disableSlashCommands parameter at line 19137 with default value false
  • When enabled, the commands list is replaced with an empty array
  • Evidence: Parameter defined at line 19137, conditional at line 19191

Git Rebase/Merge State Detection#

What: Claude now detects when git is in the middle of a rebase, merge, cherry-pick, or revert operation and skips the diff display to avoid confusing partial state.

Details:

  • Added rm5() function at line 405566 that checks for git state files:
  • MERGE_HEAD - merge in progress
  • REBASE_HEAD - rebase in progress
  • CHERRY_PICK_HEAD - cherry-pick in progress
  • REVERT_HEAD - revert in progress
  • The ky2() function at line 405477 now calls rm5() and returns early if any state file exists
  • Evidence: New function added at line 16108, integration at line 17927

WebFetch Documentation Mode#

What: WebFetch now has a special mode for fetching documentation that allows including code examples without the strict quote limits.

How it works: When fetching from llms.txt or documentation sources, the response can include full code examples and documentation excerpts rather than being limited to 125-character quotes.

Details:

  • Added Zp0() function at line 53880 with conditional prompt generation
  • When the isDocumentation flag is true, uses prompt: "Include relevant details, code examples, and documentation excerpts as needed"
  • When false, uses the standard restrictive prompt with 125-character quote limits
  • Added ZzB variable at line 182657 pointing to https://platform.claude.com/llms.txt
  • Evidence: New function at line 7427, parameter added to md2() at line 18044-18045

Model Name Display Function#

What: New helper function that formats model identifiers into user-friendly "Claude" prefixed names.

Details:

  • Added PCB() function at line 181670
  • Transforms model IDs like "sonnet" into "Claude Sonnet"
  • Returns just "Claude" if the model name is unchanged after transformation
  • Evidence: Function at line 7462-7468

React Reconciler Update#

What: Updated internal React reconciler with scheduler improvements for better performance.

Details:

  • Added new scheduler functions including Hg1(), taA(), aaA() for priority queue management
  • Added Dg1() for work loop execution with expiration handling
  • Added timing functions Iy(), PzB() for deadline checking
  • These are internal React infrastructure updates that improve rendering performance

Inbox Message Handling Improvements#

  • Inbox polling now properly queues messages when session is busy
  • Messages are delivered when session transitions from busy to idle
  • Improved logging with [InboxPoller] prefix for debugging

Query Return Value Handling#

  • The onQuery callback no longer returns a status object
  • Simplified concurrent query handling that just returns early without status
