+
+{/* MANUAL-CONTENT-START:intro */}
+[Devin](https://devin.ai/) is an autonomous AI software engineer by Cognition that can independently write, run, debug, and deploy code.
+
+With Devin, you can:
+
+- **Automate coding tasks**: Assign software engineering tasks and let Devin autonomously write, test, and iterate on code
+- **Manage sessions**: Create, monitor, and interact with Devin sessions to track progress on assigned tasks
+- **Guide active work**: Send messages to running sessions to provide additional context, redirect efforts, or answer questions
+- **Retrieve structured output**: Poll completed sessions for pull requests, structured results, and detailed status
+- **Control costs**: Set ACU (Autonomous Compute Unit) limits to cap spending on long-running tasks
+- **Standardize workflows**: Use playbook IDs to apply repeatable task patterns across sessions
+
+In Sim, the Devin integration enables your agents to programmatically manage Devin sessions as part of their workflows:
+
+- **Create sessions**: Kick off new Devin sessions with a prompt describing the task, optional playbook, ACU limits, and tags
+- **Get session details**: Retrieve the full state of a session including status, pull requests, structured output, and resource consumption
+- **List sessions**: Query all sessions in your organization with optional pagination
+- **Send messages**: Communicate with active or suspended sessions to provide guidance, and automatically resume suspended sessions
+
+This allows for powerful automation scenarios such as triggering code generation from upstream events, polling for completion before consuming results, orchestrating multi-step development pipelines, and integrating Devin's output into broader agent workflows.
+{/* MANUAL-CONTENT-END */}
+
+
+## Usage Instructions
