A cupel is a small vessel for refining precious metal. This project borrows that idea: separate useful code context from repository noise, then feed the refined signal into fast local agent workflows.

cupel is a lean Rust coding harness focused on provider-neutral inference, deterministic tooling, CLI/TUI workflows, and efficient code retrieval. Search and reranking will lean on fff, with parts of the architecture inspired by pi.dev and parts shaped around my own coding workflows.

The inference crate builds the foundation.
