tricorder

tricorder empowers developers and LLM coding agents working with Haskell by surfacing the right information at each stage: build status, diagnostics, test results, and documentation.

Like ghcid and ghciwatch, it rebuilds continuously on every change and reports diagnostics — but it runs builds in a background daemon so multiple clients (an interactive TUI, a tricorder status CLI, a Claude Code skill) can query a single shared build state without triggering redundant rebuilds. It discovers components across multi-package cabal.project workspaces automatically and ships context-friendly output for agentic use.

See the repository README for installation (Nix, Home Manager, NixOS), Claude Code plugin setup, configuration, and custom key bindings.

Built on atelier

tricorder is built on the atelier toolkit, also developed in this repository:

• atelier-prelude — relude-based prelude with Effectful conventions
• atelier-core — foundational effects and utilities
• atelier-db — relational database effect (Hasql/Rel8)
• atelier-testing — database-backed test utilities
