Harness Acquires Augment Code, Advancing the Autonomous SDLC from Idea to Production

Introducing the Harness Cosmos Software Factory Agent, connecting code and delivery data so engineering work moves from idea to production without losing context.

SAN FRANCISCO, Oct. 8, 2026 /PRNewswire/ -- Harness, the Autonomous SDLC Platform^TM company, today announced that it has acquired select Augment Code assets, including Cosmos and the Auggie CLI products, the Code Context Engine, and related technology. The team behind these products will join Harness, accelerating its work to make the entire software development lifecycle increasingly autonomous.

Cosmos will become Harness Cosmos Software Factory Agent, with a clear role: automate engineering work from idea to code. From there, Harness's existing agents for software delivery, security testing, runtime protection, and cost management take over, carrying the work into production and operations, creating a seamless agent to agent experience.

Connecting Augment's Code Context Engine with Harness's Software Delivery Knowledge Graph provides insights across the full SDLC — what's being built, and what happens to it once it ships. Harness is bringing codebase understanding together with delivery context, so Harness Cosmos can make better-informed changes upfront, and Harness agents can use downstream findings to correct and verify them.

"AI's impact on software will not be measured by how much code it generates, but by how much valuable software reaches customers," said Jyoti Bansal, founder and CEO of Harness. "Augment Code built Cosmos to create a software factory for repeatable engineering work. With this acquisition, we are bringing code context together with delivery and production context to help agents make better changes from the start. When Harness downstream agents identify an issue while testing, securing, or deploying code, they send it back to Cosmos with the context to fix it."

"We set out to bring AI to the entire software development lifecycle, starting with context-aware coding," said Igor Ostrovsky, co-founder and CTO of Augment Code. "Joining Harness is the next step toward that vision. Together, we can make engineering work increasingly autonomous, with engineers stepping in only where judgment really matters. We've seen software factories transform how companies build software. Now, with Harness, that same transformation is within reach for every team already on the Harness platform — and every team getting started."

Introducing the Harness Cosmos Software Factory Agent

Harness Cosmos takes engineering work from idea to merge-ready code. When a requirement is written, a ticket is assigned, or a bug is reported, a fleet of Cosmos agents plans the change, writes the code and tests, and opens a pull request. Each agent works in its own isolated VM and pulls in an engineer only where judgment is needed, like approving a design or making the final merge.

Cosmos agents run as a continuous loop through ticket, code, and review. When a reviewer comments or a check fails, an agent fixes the issue on the same pull request. Teams can fork prebuilt Experts like Project Builder, PR Author, Deep Reviewer, and PR Fixer, tune each one to their own codebase, and deploy it organization-wide.

Augment's Code Context Engine keeps a live map of the codebase, so changes fit the code already there. Model routing matches each task to the right model, and built-in integrations connect to GitHub, Jira, and Slack. Shared memory carries lessons from each review into the next change, and versioning and budget controls let teams run autonomous coding across the entire engineering organization.

What leaves the factory is a reviewed pull request, ready for Harness agents to test, secure, and deploy.

Shared context from code to production
Harness's Software Delivery Knowledge Graph connects delivery and operational information, including builds, deployments, infrastructure, security, and costs. Augment's Code Context Engine brings that same specificity to the code itself.

Before a change is written, Harness Cosmos will pull together the delivery context that should shape it: test cases, security requirements, past incidents and their remediations. Once that change exists, Harness's downstream agents will use codebase context to reason about dependencies, risk, and what validation it needs. If something fails, the agents can loop until resolution.

Extending the Harness Autonomous SDLC Platform
Harness Cosmos joins the Harness platform, automating engineering work from idea to code. No matter how that code is written, the Harness platform already takes it the rest of the way:

• Software Delivery Agent moves changes safely to production
• Security Testing Agent finds and fixes risk before production
• Runtime Protection Agent protects applications, APIs, and AI in production
• Cost Management Agent controls and optimizes cloud and AI costs

The integration vision focuses on connecting Harness Cosmos workflows with the policies, permissions, and approvals that already govern the Harness platform, bringing the same discipline to creating a change that enterprises already expect when releasing one.

Frequently Asked Questions (FAQs)

Q: What is the news?
A: Harness has acquired select assets from Augment Code, the company behind Cosmos and the Auggie CLI. Cosmos is a programmable software factory that runs a fleet of AI agents taking engineering work from idea to merge-ready code. The acquisition brings Cosmos into the Harness Autonomous SDLC Platform, connecting agent-driven development work with the Harness Agents that already manage software delivery, security testing, runtime protection, and cost management.

Q: What is Augment Code?
A: Augment Code is the company behind Cosmos, a software factory that runs a fleet of AI agents that trigger on events like a pull request opening, an alert firing, or a webhook landing. Agents run as continuous loops covering workflows like code review and ticket-to-PR, with engineers in control at each checkpoint.

Q: Why did Harness acquire the assets of Augment Code?
A: Augment Code's Cosmos will become the Harness Cosmos Software Factory Agent, with a clear role: automate engineering work from idea to code. From there, Harness's existing agents for software delivery, security testing, runtime protection, and cost management take over, carrying the work to production, creating a seamless agent to agent experience.

Q: What is the Harness Autonomous SDLC Platform?
A: The Harness Autonomous SDLC Platform handles everything after code:

• Software Delivery Agent moves changes safely to production
• Security Testing Agent finds and fixes risk before production
• Runtime Protection Agent protects applications, APIs, and AI in production
• Cost Management Agent controls and optimizes cloud and AI costs

Q: How will Cosmos by Augment Code integrate with the Harness Autonomous SDLC Platform?
A: Cosmos will handle the idea to merge-ready code, coordinating agents from idea through implementation, review, and verification. From there, Harness Agents — Software Delivery, Security Testing, Runtime Protection, and Cost Management — take the change to production. Before a change is written, Harness Cosmos pulls together the delivery context that should shape it: test cases, security requirements, historical incidents and remediations. Once that change exists, Harness's downstream agents use codebase context to reason about dependencies, risk, and what validation it needs. If something fails, the agents can loop until resolution.
