Ante is an open-source, Rust-based CLI coding agent developed by AntigmaLabs. Built specifically for terminal-first development workflows, Ante provides a fast, modular runtime designed to execute automated software engineering tasks across local repositories. In day-to-day development, Ante executes from the command line, leveraging internal subsystems such as `ante-harbor` for runtime event orchestration and `ante-acp` for standardized agent communication protocols. The agent processes instructions, analyzes codebase context, and executes structured code generation and modification workflows driven by curated configuration profiles. Ante distinguishes itself through its native Rust implementation and modular crate architecture. Unlike heavier scripting-language agents, Ante emphasizes low execution latency, deterministic process iteration, and extensible architecture through dedicated event-handling and protocol crates. Ante is currently distributed in public preview releases on GitHub, providing an evolving set of crates and pre-configured execution profiles for early adopters.
Rust-native modular core — Implemented as a modular workspace of Rust crates for minimal footprint and optimal runtime performance. - ante-harbor runtime harness — Dedicated event orchestration module supporting event iterables and reactive agent operation loops. - ante-acp integration — Implements Agent Client Protocol (ACP) support for standardized agent interaction and tooling integration. - Curated execution profiles — Ships with curated planning and execution profiles to structure step-by-step code generation tasks. - Terminal-centric interface — Designed to run entirely within standard developer terminal environments without requiring external desktop runtimes.
Use cases
Use Case: Plan-Driven Codebase Refactoring Developers can invoke Ante with curated planning profiles to systematically plan, inspect, and apply multi-file code modifications across large repositories directly from the shell.
Use Case: Protocol-Standardized Agent Tooling Teams building custom developer environments can integrate Ante's ante-acp client protocol components to orchestrate the coding agent across decoupled client-server setups.
Use Case: Scripted Terminal Task Automation Engineers can embed Ante's CLI into automated local development pipelines or CI environments to handle routine code modifications and event-driven code validation.
Who it is for
Ante is designed for systems engineers, Rust developers, and command-line power users who prefer lightweight, native CLI coding agents over heavyweight electron apps or web environments. It is not intended for non-technical users seeking graphical click-and-drag AI assistants.
Install guide
Installation Ante is distributed as a Rust project. You can clone the repository and build it locally using Cargo: bash git clone https://github.com/AntigmaLabs/ante.git cd ante cargo build --release Ensure the compiled binary in target/release/ is added to your system PATH.
First Run Verify that the Ante executable is accessible and inspect available profiles: bash ante --help Ensure your LLM provider credentials or API environment variables (such as OPENAI_API_KEY or ANTHROPIC_API_KEY) are exported in your current shell session.
Example Session Run Ante in your project directory using a curated planning profile: bash ante run --profile curated/plan "Refactor the event handling logic in the core module to support stream iterators"
