HEAV3NS

HEAV3NS is a local-first CLI coding agent designed for focused, reviewable work. It operates as a command-line tool that assists with coding tasks by inspecting context, making scoped changes, and verifying them before handing control back to the developer. The project emphasizes a tight coding loop, with features such as project-aware search, reviewable recovery, and cost-aware context management. According to the website, "HEAV3NS takes the fighter-jet mission: one focused coding task close to the code—inspect context, make a scoped change, verify it, then hand control back to the developer." The tool is built to be used locally, with provider and network time remaining visible as separate costs.

The agent includes a set of predefined AI specialists, such as coder, researcher, sre, writer, student, and minimal, each tailored for different tasks. Users can switch between these profiles and even create custom assistants by dropping notes or script files into a folder. The website states, "Drop any notes or script files into a folder to create a personalized AI assistant." HEAV3NS also provides features like typo-friendly smart matching, port diagnostics, and context and cache telemetry to help users understand provider usage. It is designed to be observable, with health checks, tests, and telemetry to make behavior easier to inspect.

HEAV3NS is open-source and licensed under the Apache License 2.0. It is inspired by hermes-agent by Nous Research and is dedicated to the open-source community. The project includes extensive documentation, including architecture guides, benchmark measurements, and a verification suite. The website notes, "Current first-party work is offered under the Apache License 2.0." The tool aims to provide a reliable and transparent coding assistant for developers who prefer a CLI-based workflow.
