Summary

Terminal-based AI assistant with TUI interface, multi-provider support, and MCP extensibility. Successor to OpenCode, developed by Charmbracelet team with "glamorous agentic coding for all." Features LSP integration, cross-platform support (macOS, Linux, Windows, Android, BSDs), and comprehensive Model Context Protocol support across stdio, HTTP, and SSE transports.

Assessment

HIGH VALUE for harness assimilation - modern terminal AI interface with sophisticated MCP integration and skill system. Active development with 22K+ stars indicates strong community adoption. However, lack of stop hooks limits full babysitter integration potential.

Extraction Priority

• High
• Rationale: Active successor to OpenCode with modern architecture and strong MCP support. TUI patterns and session management valuable for babysitter observer dashboard improvements.

Harness Integration Ideas

**Capability Assessment for Babysitter Integration:**

**Integration Viability:** PARTIAL - Excellent MCP integration and skills system but **lacks critical stop-hook capability** for babysitter's orchestration loop interruption needs.

- Adapter implementation: createCrushAdapter in packages/sdk/src/harness/adapters/ - Plugin structure: plugins/babysitter-crush/ for Charmbracelet Crush integration - CLI integration: Terminal UI patterns, session management, MCP server orchestration - Current limitation: **No stop hooks for conversation interruption** - Integration approach: Custom conversation pause/resume mechanism required - Implementation scope: Terminal UI adaptation, MCP protocol bridging, session state management

• **Harness Adapter**: New harness integration for Crush platform

TUI/Orchestration Improvements

- Current limitation: Basic terminal output vs. polished TUI experience - Integration approach: Import Charmbracelet's TUI libraries and design patterns - Implementation scope: Observer dashboard visual enhancement, terminal UI modernization

• **Terminal Interface Patterns**: Adapt Crush's glamorous TUI design for babysitter observer dashboard

- Current limitation: Single-context babysitter runs vs. multi-session capability - Integration approach: Implement session switching and context isolation - Implementation scope: Run directory organization, session state persistence

• **Session Management**: Multi-context session architecture for project-specific agent state

Implicit Procedural Knowledge

None - framework rather than process repository.
