Show HN: Higgs, a local AI CLI for Proton Mail (no cloud, no telemetry) (github.com)

Higgs, an independent community-built command-line interface (CLI) for Proton Mail, has been announced, featuring a unique agent-first design that emphasizes integration with language models. Unlike traditional CLIs that rely on human interaction, Higgs is structured to be driven directly by an AI model, simplifying the process of command execution through a JSON schema manifest that details subcommands and their parameters. Key features include NDJSON streaming for structured output, typed error envelopes for consistent error handling, deterministic exit codes, and a state database to support resumable operations. This project is significant for the AI/ML community as it promotes enhanced interoperability between AI models and email management systems without relying on cloud infrastructure, thereby ensuring privacy and data security. Higgs allows users to locally classify their Proton Mail inbox using models like Ollama's Gemma 4, which features a 128K context window. By streamlining the integration of AI with email utilities, Higgs offers a promising approach for developers and users looking to leverage machine learning in day-to-day operations while maintaining full control over their data.
