The agent
Devin is an autonomous software engineering agent from Cognition. Given a ticket or a brief, it plans, clones the repo, edits code, runs the build and tests, and opens a pull request for human review.
- Ticket-to-PR workflow: works from Jira, Linear or GitHub issues to a reviewed pull request.
- Full dev environment: shell, browser and editor in an isolated runtime, so it can run tests and reproduce bugs, not just suggest code.
- Repository rules and knowledge: system prompts and playbooks tuned to your architecture, API contracts and linting standards.
- Execution inside your perimeter: agent planning stays in the vendor cloud; all repo cloning, shell commands and builds run on your infrastructure via outbound-only connections. Nothing inbound, nothing egressing your code.
