Devin

Devin 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.

Usage Instructions

Integrate Devin into your workflow. Create sessions to assign coding tasks, send messages to guide active sessions, and retrieve session status and results. Devin autonomously writes, runs, and tests code.

Actions

devin_create_session

Create a new Devin session with a prompt. Devin will autonomously work on the task described in the prompt.

Input

Output

devin_get_session

Retrieve details of an existing Devin session including status, tags, pull requests, and structured output.

Input

Output

devin_list_sessions

List Devin sessions in the organization. Returns up to 100 sessions by default.

Input

Output

devin_send_message

Send a message to a Devin session. If the session is suspended, it will be automatically resumed. Returns the updated session state.

Input

List the files uploaded to or produced by a Devin session.

Input

Output

devin_get_session_tags

Retrieve the tags currently applied to a Devin session.

Input

Add tags to a Devin session without removing existing tags (max 50 tags total).

Input

Output

devin_replace_session_tags

Replace all tags on a Devin session with a new set of tags (max 50 tags).

Input

Output

devin_archive_session

Archive a Devin session. Archived sessions can still be viewed but cannot be modified or resumed.

Input

Output
