Ouyang

What This Skill Does

Ouyang (Jasper Recall) provides a persistent, long-term memory layer for OpenClaw agents. By leveraging ChromaDB as a vector database and sentence-transformers for semantic processing, it transforms disparate session logs, daily notes, and documentation into a queryable knowledge base. Unlike ephemeral chat history, this skill allows agents to "remember" architectural decisions, meeting outcomes, and project context across months of development.

Installation

To integrate Ouyang into your OpenClaw environment, use the following command: clawhub install openclaw/skills/skills/ttboy/ouyang

Once installed, initialize the environment using npx jasper-recall setup. This will configure the necessary virtual environment and vector database storage at ~/.openclaw/chroma-db.

Use Cases

• Project Continuity: Instantly retrieve context from previous development sessions or design debates.
• Daily Note Synthesis: Query your own notes to find patterns in your daily workflows or reminders about task priority.
• Agent Documentation: Build a searchable knowledge base from existing Markdown files, allowing the agent to answer questions based on your specific project documentation.
• Knowledge Retrieval: Use the agent to extract information from meeting digests without manually scrubbing through logs.

Example Prompts

1. "Recall what the team decided regarding the authentication middleware in last week's meeting."
2. "Search my daily notes for any mentions of 'performance bottlenecks' and summarize them."
3. "Look through the memory logs and explain why we chose PostgreSQL over MongoDB for this project."

Tips & Limitations

• Maintenance: Treat the indexing process as a routine task. Set up a heartbeat or cron job to run digest-sessions and index-digests periodically so your memory index stays current.
• Performance: The skill uses all-MiniLM-L6-v2, which is optimized for speed and low-latency retrieval. While excellent for text, it is not designed to index large binary files or massive datasets.
• Scoped Memory: Keep your ~/.openclaw/workspace/memory/ directory organized; the skill is most effective when files are clearly labeled with dates or topics, making the semantic retrieval more precise and reducing "hallucination" based on irrelevant chunks.
