Treasures Behind the Curtain

Hidden within Claude Code’s source are many features not yet fully public or still in experimental stages. They represent the future direction of AI programming assistants — from persistent assistants to remote control, from automatic memory consolidation to multi-agent coordination.

Kairos: The Always-On AI Companion

Feature Flag: KAIROS | Status: Experimental

Kairos mode transforms Claude Code from “on-demand conversation” to “persistent assistant.” When enabled:

• Claude Code runs continuously, receiving messages through Channels (such as GitHub Webhooks)
• Uses daily-log memory mode instead of per-session records
• Automatically consolidates memory, maintaining continuity across sessions
• Supports session resumption via --session-id and --continue

Source: src/bootstrap/state.ts → getKairosActive() / setKairosActive()

AutoDream: Automatic Memory Consolidation

Feature Flag: GrowthBook tengu_onyx_plover | Status: Shipped

During idle periods when you’re not using Claude Code, AutoDream automatically organizes and consolidates memories in the background. Trigger conditions (checked from lowest to highest cost):

1. Time gate: At least 24 hours since last consolidation
2. Session gate: At least 5 new sessions since last consolidation
3. Lock gate: No other process is currently consolidating (file lock)

The consolidation runs as a read-only subagent, extracting key memories and updating memory files. Includes scan throttling (10 minutes) to prevent excessive polling.

UltraPlan: Remote Deep Planning

Feature Flag: GrowthBook tengu_ultraplan_model | Status: Shipped

Via the /ultraplan command, delegate complex planning tasks to Claude Code on the Web (CCR), using the most powerful Opus model for extended thinking:

• Launches a remote session on code.claude.com
• Supports user-provided initial plan seeds
• 30-minute timeout with status polling
• Upon completion, choose to execute locally or continue remotely

Source: src/commands/ultraplan.tsx + src/utils/ultraplan/

Coordinator Mode: Multi-Agent Orchestrator

Feature Flag: COORDINATOR_MODE | Status: Experimental

Coordinator mode turns the main agent into a commander, dispatching multiple parallel Workers via AgentTool:

• Workers can use the full toolset or a simplified toolset (CLAUDE_CODE_SIMPLE=1)
• Optional scratchpad directory for cross-Worker knowledge sharing
• Task completion notifications use <task-notification> XML format

Source: src/coordinator/coordinatorMode.ts → isCoordinatorMode()

Bridge: Remote Control

Feature Flag: BRIDGE_MODE | Status: Shipped

Bridge lets you remotely control Claude Code from a browser (claude.ai), IDE (VS Code, JetBrains), or mobile device:

• Register environment → poll for work requests → spawn subprocess → route I/O
• Three spawn modes: single-session (one-shot), worktree (Git Worktree isolation), same-dir (shared directory)
• JWT authentication + heartbeat lease renewal

Source: src/bridge/bridgeMain.ts (2800+ lines)

Daemon Mode: Background Sessions

Status: Shipped (part of team/swarm features)

Spawn background subagent sessions via Tmux or iTerm2:

• Run complete Claude Code sessions independently in the background
• Communicate with Leader through mailbox files (Unix socket abstraction)
• Leader routes permission requests to ToolUseConfirmQueue

Source: src/utils/swarm/backends/TmuxBackend.ts

Buddy: Virtual Pet Companion

Feature Flag: BUDDY | Status: Shipped (Easter egg)

A hidden animated sprite that sits quietly beside the input field:

• Has idle, fidget, and blink animation sequences
• Shows a speech bubble when you say its name
• /buddy pet command makes it emit hearts
• Supports rarity color coding

Source: src/buddy/CompanionSprite.tsx (1000+ lines)

UDS Inbox: Inter-Process Communication

Status: Shipped (team infrastructure)

A file-system mailbox-based message queue system supporting Leader-Teammate communication:

• Teammate polls inbox every 1 second
• Supports permission request/response, plan approval, close request, and other message types
• Deduplication mechanism prevents duplicate processing
• Crash recovery via mtime replay

Source: src/hooks/useInboxPoller.ts (970 lines)

These hidden features and experimental capabilities sketch Claude Code’s ultimate vision: not merely a reactive coding assistant, but an always-on, self-evolving, multi-device AI development environment. From Kairos’s persistent companionship to AutoDream’s automatic memory consolidation, from Bridge’s remote control to Daemon’s background execution — each feature pushes the boundaries of what an “AI programming assistant” can be. And Buddy’s presence reminds us that even the most serious engineering tools need a touch of warmth and whimsy.
