Open-source memory for coding agents, synced over SSH
TL;DR
Coding agents like Claude Code and Codex generate extensive local histories of conversations, which are often unsearchable. Deja is a new tool that creates a memory layer from these histories without requiring additional models or services.
✦ Why It Matters
Engineers can implement Deja today to enhance their coding workflow by easily accessing past interactions and decisions.
Key Takeaways
- Install Deja to index your coding history for quick access.
- Utilize agent recall to avoid redundant debugging efforts.
- Sync your memory across devices using SSH for seamless access.
- Redact sensitive information automatically during indexing.
How It Works
Deja operates by indexing local files created by coding agents, allowing users to search through months of historical data quickly. It uses a connection pool to serve search results in about 12 milliseconds, enabling agents to recall past solutions and decisions without needing to re-debug.
The tool also supports auto-recall features that inject relevant historical context into new sessions, enhancing the coding experience.
