Harness for Agents: Introducing a New Platform Experience
Harness, Thursday, November 5th, 2026
Harness rebuilt its platform with a new pipeline model designed so agents and people author, review and run the same definitions.
Harness introduced a new platform experience built for software delivery in which AI agents work alongside people.
The re-architected pipeline layer replaces capability-specific stages with one flexible stage and execution model, so build, deploy, security, infrastructure and agentic work run with reusable step plugins.
The YAML is flatter and closer to Drone and GitHub Actions, with Smart Defaults keeping only pipeline-specific configuration in files.
Harness keeps JEXL expressions and adds CEL with ${{ }} syntax, and pipeline inputs now support lists, structured objects, secrets and connectors resolved with current permissions.
