About

Augment Code is an agentic development platform built to help engineering teams move from isolated AI coding assistants to a coordinated system of software agents. Its Cosmos platform runs software agents at scale, giving them the context, tools, environments, memory, and feedback loops they need to improve with every workflow. Cosmos works across the software development lifecycle, with reusable expert agents for authoring pull requests, reviewing changes, analyzing risk, testing updates, and helping teams build their own specialized workflows. Its PR Author can take a task description from first commit through merge, while Pair Review reviews changes alongside the author, Deep Code Review reads pull requests end to end and posts inline comments, PR Risk Analysis surfaces blast radius, security exposure, and migration risk, and Tester exercises changes end to end with results and screenshots included.

About

Leanstral is an open-source code agent developed by Mistral AI specifically designed to work with the Lean 4 proof assistant. The model focuses on generating code while also formally verifying its correctness against strict mathematical or software specifications. Unlike traditional coding assistants, Leanstral integrates directly with formal proof systems to ensure that generated code satisfies defined logical requirements. Its architecture is optimized for proof engineering tasks and operates efficiently with sparse model parameters. Leanstral is released under the Apache 2.0 license, making it freely accessible for developers, researchers, and organizations to use and customize. The model is designed to operate within real-world formal repositories rather than isolated problem environments. By combining code generation with formal verification, Leanstral aims to reduce the need for manual human review in complex software and mathematical development.
