Version 2.0.65

What: A new command to add searchable tags to your sessions for better organization and retrieval. How to use:

/tag bugfix        # Add tag to current session
/tag bugfix        # Run again to remove (toggle behavior)
/tag feature-auth  # Use descriptive names

Details:

• Tags appear after the branch name in /resume list
• Tags are searchable with / search functionality
• Running the same tag command again removes the tag (toggle)
• Evidence: c55() at line 483604, HG0() at line 491331, nh2() at line 491336

What: New consolidated tool that retrieves output from any task type (background shells, agents, or remote sessions). How to use:

# Model uses TaskOutput instead of separate BashOutput/AgentOutputTool
TaskOutput --task_id <id> --block true --timeout 30000

Details:

• Replaces the previous BashOutput and AgentOutputTool with a single unified interface
• Works with local bash tasks, local agents, and remote agent sessions
• Supports blocking and non-blocking retrieval modes
• Evidence: BH = "TaskOutput" at line 375878, R31 tool definition at line 454807

What: MCP tools can now be loaded on-demand to reduce initial token overhead. How to use:

• Configure in settings; MCP tools marked for deferred loading won't count against initial token budget
• Tools load when needed during conversation

Details:

• New "MCP tools (deferred)" category shows in /context breakdown
• Deferred tools excluded from main token total until used
• Evidence: deferredToolTokens: H at line 380202, defer_loading property in fQ1() at line 457318

What: Claude Code now detects and works with git worktrees for multi-branch development workflows. Details:

• Automatically detects worktree configurations
• Reports worktree paths to session context
• Telemetry event tengu_worktree_detection tracks usage
• Evidence: worktree parsing logic starting at line 2461

What: After task completion, Claude now suggests the next logical prompt based on conversation context. Details:

• Suggestions appear as placeholder text in input field (press Enter to accept)
• Filters inappropriate suggestions (too long, gratitude responses, etc.)
• Telemetry tracks acceptance rates
• Evidence: HN2() at line 440590, wN2() at line 441103, _B5() at line 441117

What: Built-in performance profiling for SDK/headless usage with turn-level metrics. How to enable:

export CLAUDE_CODE_PROFILE_STARTUP=1  # Enable verbose logging

Details:

• Tracks key checkpoints: system message generation, query start, first response chunk
• Reports metrics via telemetry for 5% of sessions
• Evidence: e30(), p1A(), A80() functions at lines 445732-445745

What: Custom hook support for file path suggestions during @ mentions. Details:

• Configure via fileSuggestion in hooks settings
• Supports command-type hooks that receive query context and return file paths
• Evidence: E60() at line 460683, hook check in dH2() at line 424845

What: Full CLI support for plugin enable/disable/update operations. How to use:

claude plugin enable <name> --scope user
claude plugin disable <name> --scope project
claude plugin update <name> --scope local

Details:

• Enable disabled plugins: jRA() at line 451234
• Disable enabled plugins: PRA() at line 451237
• Update specific plugins: SRA() at line 451240
• Supports scope-aware operations (user/project/local)
• Evidence: Ld2(), Md2(), Od2(), Rd2(), Td2() CLI handlers at lines 497930-498062

What: Background auto-update for installed marketplace plugins. Details:

• Runs automatically on startup (non-headless mode only)
• Updates each marketplace sequentially with error isolation
• Evidence: _j2() at line 450763

What: Infrastructure for generating session teleport links to claude.ai. Details:

• Generates URLs in format: https://claude.ai/code/{sessionId}
• CLI command format: claude --teleport {sessionId}
• Evidence: TtB() at line 369714, _tB() at line 369717

Background tasks now include delta summaries in attachments for smoother conversation flow. New function o78() at line 358386 handles task status attachment generation with status, description, and delta summary fields.

Added framework for enterprise remote settings synchronization including authentication, validation, and local caching. New file remote-settings.json at line 3494 and related authentication handling.

LSP operations now use 1-based line/character positions (matching editor display) instead of 0-indexed. This affects goToDefinition, findReferences, hover, documentSymbol, and workspaceSymbol operations. Evidence: Schema definitions at line 455590.

New function zy2() at line 462818 provides detailed information about active settings sources, distinguishing between remote and local enterprise managed settings.

Plugin tracking migrated to v2 format with per-installation metadata including scope, project path, version, and timestamps. Functions Q31() at line 447959 and IM2() at line 447977 handle the new format.

Sessions can now be searched by tag in addition to content. Function $h() at line 491493 supports multi-path session loading with tag filtering.

New DISABLE_COMPACT environment variable allows disabling auto-compact behavior. Function wAA() at line 4001 checks this setting.

New MCP tool discovery tool schema (XwZ, WwZ) at line 456454 enables dynamic MCP tool querying with configurable result limits.
