Hugging Face has released funes, a tool that transforms existing coding agent session logs into a durable, searchable memory layer for Claude Code, Codex, pi, and Hermes. It indexes traces locally using vector and BM25 search, allowing agents to retrieve exact provenance without external services.
- Supports Claude Code, Codex, pi, and Hermes with a single binary installation.
- Uses local embedding and reranking models, storing data in Lance datasets.
- Allows binding memories to private Hugging Face datasets for cross-machine sync.
- Includes a 'recall' tool for agents and an 'ask' command for direct queries.
The release aims to prevent context loss by enabling agents to recall past decisions and rationale across sessions and machines, offering a cheaper alternative to session compaction or manual handoffs.
