Description

The Harness Cosmos Software Factory Agent is a cloud-based platform designed to automate software engineering processes, facilitating the transition from issues or events to code modifications and pull requests. Teams have the ability to customize agent workflows by incorporating specialized experts, various execution environments, triggers, integrations, and checkpoints for human approval. These workflows can be initiated through ticket updates, pull requests, alerts, scheduled tasks, or webhooks; the agents can autonomously investigate tasks, devise changes, write code along with tests, create pull requests, and handle feedback from reviews. An integral feature is the code context engine, which fetches pertinent information from the codebase, while sandboxed virtual machines ensure a secure execution environment. Organizations involved in software engineering and platform development can utilize Cosmos to manage agent-led tasks such as implementation, code review, verification, and other associated development activities, benefiting from shared organizational knowledge, historical version tracking of workflows, audit logs, and controls for managing automation budgets. Furthermore, the streamlined collaboration afforded by these features enhances overall productivity within teams, making the software development process more efficient.

Description

Mesrai serves as a collaborative AI-driven code review platform designed specifically for engineering teams. It employs a team of five specialized agents—Bug, Security, Performance, Architecture, and a Playbook agent—to meticulously evaluate each pull request, utilizing a comprehensive graph of your codebase that details the effects of every modification across both monorepos and various repositories. The review process features inline feedback that includes severity ratings and recommended improvements, while Mesrai also monitors DORA metrics to assess the overall health of engineering practices. Users can utilize their own LLM key and make payments directly to their chosen provider. The reviews take place in temporary sandboxes, ensuring that your code is never utilized for training purposes. Additionally, Mesrai offers compatibility with a VS Code extension, command-line interface (CLI), and various MCP plugins, making it a versatile tool for developers. This platform enhances collaborative efforts while promoting best practices in code quality and security.
