tricorder: Continuous Haskell build status, diagnostics, and tests via a shared daemon

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

[maintain] [Publish]

tricorder rebuilds your Haskell project continuously and surfaces build status, diagnostics, test results, and documentation - for developers and LLM coding agents. Like ghcid and ghciwatch it reloads on every change, but builds run in a background daemon so multiple clients (an interactive TUI, a status CLI, an agent skill) share a single build state without triggering redundant rebuilds. It discovers components across multi-package cabal.project workspaces automatically and ships context-friendly output for agentic use via the CLI.

Readme for tricorder-0.2.2.1

[back to package description]

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.
