Claude Code v2.0.36

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

• New helper function Hp2() at line 451872 formats telemetry metadata
• Structures environment context, process metrics, and core session data
• Used by telemetry exporters for consistent event formatting
• Evidence: Function Hp2(A, B = {}) at line 451872
