What: New command for Pro and Max subscribers to quickly access Claude AI usage settings How to use:

claude extra-usage

Details:

Opens https://claude.ai/settings/usage in your browser
Only available for "pro" or "max" subscription tiers
Can be disabled by setting DISABLE_EXTRA_USAGE_COMMAND environment variable
Evidence: RAI command definition at line 467420 in new function, ha2 = RAI at line 467528

What: New architecture for temporary, session-scoped hooks that automatically clean up when sessions end How it works:

Session hooks are stored separately from user settings (sessionHooks field in app state at line 141240)
Automatically cleared on session end to prevent accumulation
Support callback functions (onMatch) for programmatic responses
Cannot be removed through settings UI (protected at diff lines 2057-2059)

Details:

Three new management functions:
wB1() at line 457341 - Retrieves session hooks for a specific session
ll2() at line 457356 - Finds and returns matching hook callbacks
il2() at line 457367 - Clears all hooks for a session
Session hooks are merged with permanent hooks at execution time (merge logic in nl2() at line 457391)
Hooks are marked with source: "sessionHook" to distinguish from settings-based hooks
Designed for plugins, agents, and temporary automation without polluting user settings
Evidence: State initialization at line 141240, management functions at lines 457341-457367, integration in nl2() at lines 457391-457413

What: New telemetry backend for event logging and monitoring Details:

Sends logs to Datadog HTTP intake endpoint: https://http-intake.logs.datadoghq.com/api/v2/logs
Controlled by feature gate tengu_log_datadog_events (gate name at line 477899)
Batches events for efficiency (batch size threshold KBI, flush interval VBI = 15000ms at line 477634)
Includes context tags: user type, version, model, session ID, platform details
Automatic flush on process exit
Evidence: FBI constant at line 477632, gate check er2 at line 477899, batching logic in QB0() at line 477567 and BB0() at line 477543

What: First-party event logging using OpenTelemetry protocol Details:

Exports events to Anthropic's event logging endpoint: {ANTHROPIC_BASE_URL}/api/event_logging/batch
New exporter class IB0 at line 477676 handles batching and export
Transforms logs into ClaudeCodeInternalEvent format with environment context
Logger initialization in or2() at line 477773 with automatic shutdown handling
Controlled by feature gate tengu_log_1p_events (gate check in rr2() at line 477755)
Events include session context, environment details, and custom metadata
Evidence: IB0 class at lines 477676-477751, initialization or2() at line 477773, event emission ZB0() at line 477761

What: Plugin loading now detects and prevents duplicate hook file loading How it works:

Uses realpathSync() to resolve canonical file paths (at line 275643 in BwQ())
Tracks loaded hook files in a Set to detect duplicates
In strict mode (default), duplicate hooks trigger errors with helpful messages
Automatically loads hooks/hooks.json if it exists, so manifest shouldn't reference it

Details:

New 5th parameter added to plugin loading function BwQ(A, B, Q, I, G = !0) where G controls strict mode (function signature at line 275505)
Strict mode enabled by default but can be disabled via marketplace entry's strict: false property (call site at line 275831)
Enhanced logging: "Loaded hooks from standard location for plugin..." (at line 275647)
Error message explains the issue: "The standard hooks/hooks.json is loaded automatically, so manifest.hooks should only reference additional hook files" (at lines 275696-275697)
Prevents common plugin authoring mistakes and duplicate hook registrations
Evidence: Function BwQ() at line 275505, duplicate detection at lines 275689-275707, Set tracking at line 275637

What: Session end processing now includes session hook cleanup and accepts additional configuration Details:

Function renamed from Hf1() to Tf1() with enhanced parameters (signature at line 483476)
Now accepts options object with getAppState, setAppState, signal, timeoutMs
Automatically clears session hooks after executing SessionEnd hooks (cleanup call il2(I, J) at line 483506)
Prevents session hook accumulation across multiple sessions
Evidence: Old function Hf1 at line 482867 (removed), new function Tf1 at line 483476 (added), session hook clearing at line 483506

What: More robust detection of user "continue" commands Details:

Updated pattern matching in prQ() at line 347927
Now trims input and checks for exact "continue" match: if (B === "continue") return !0;
Also matches phrase patterns "keep going" and "go on"
Evidence: Function prQ() at line 347927, exact match check at line 347929

What: PR review workflow now triggers on more PR events Details:

Previous triggers: [opened, synchronize]
New triggers: [opened, synchronize, ready_for_review, reopened]
Ensures reviews run when draft PRs become ready for review and when closed PRs reopen
Evidence: Workflow template yp2 at line 452368, trigger definition at line 452314

Function identifier iS2 repurposed: old agent definitions renderer moved to Fy2() at line 437284
New iS2() at line 436183 is async query handler managing user input processing, checkpointing, message preparation, and queue processing
Not user-facing but improves code organization

Function renamed from sl2() to Hi2() with additional state parameter
Now merges session hooks with settings-based hooks
Updated to call nl2(A) which includes session hook integration
Evidence: Old function signature sl2(A) at diff line 1940, new signature Hi2(A, B) at diff line 1984
