Feature & Specification Comparison
Tools & Capabilities Breakdown
Conversation Handoff MCP Tools (11)
handoff_save
Save a conversation handoff for later retrieval. Use this to pass conversation context to another AI or project.
## Long conversations (>~100KB)
If the conversation is large, **save the first chunk with this tool**, then call `handoff_append` repeatedly with the remaining chunks. Doing one giant `handoff_save` can fail with an XML parse / tool-input error because Claude Code encodes tool arguments as XML internally and very large strings can break that encoding.
## Format Selection
- **structured** (default): Organize content using the template below. Much faster — reduces output tokens to ~5-20% of the original conversation. Best for most handoffs.
- **verbatim**: Save the complete word-for-word conversation. Use only when exact wording matters (e.g., legal text, precise error messages).

handoff_list
List all saved handoffs with summaries. Returns lightweight metadata without full conversation content. Opens interactive UI if supported.
handoff_load
Load a specific handoff by key. Returns full conversation content.
