High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I retrieve cross-channel chat history from past sessions?▼

Cross-channel chat history is retrieved by reading history.json files from ~/.jiuwenclaw/agent/sessions, then filtering by channel, session_id, and time to output a structured HISTORY_CONTEXT_BLOCK for injection into the current conversation.

How does keyword matching work for past conversation context injection?▼

Keyword matching for context injection scans the filtered past chat history to locate relevant messages based on your specified keywords, assembling them into a pasteable context block that informs current responses.

Can I use mcp_exec_command to fetch past session messages in JiuwenClaw workflows?▼

Yes, mcp_exec_command provides the scripting interface for JiuwenClaw workflows, allowing you to execute the script with desired channel, session_id, and time window parameters to fetch past messages seamlessly.

Does cross-channel history retrieval work across different time windows?▼

Cross-channel history retrieval applies across channels, sessions, and time windows, allowing you to specify a time range to filter past chat history and handle inquiries about earlier conversations accurately.

What is a HISTORY_CONTEXT_BLOCK and how do I insert it into the current chat?▼

A HISTORY_CONTEXT_BLOCK is a structured output of matched past messages. You insert it into the current chat by running the script with channel, session_id, and time parameters to fetch and paste the resulting context block.

What are the limitations of retrieving chat history from local session files?▼

Retrieval is limited to reading history.json files stored locally in ~/.jiuwenclaw/agent/sessions, meaning it cannot access remote sessions or histories not saved to this local directory structure.
