# Devin building Devin

Cognition's team uses Devin across Slack, Linear, web, CLI and API to write, review, triage and debug code in its own codebase.

Result: Cognition merged 659 Devin-authored PRs into its own codebase in one week, up from 154 in its best week of 2025.

## How it was set up

Repos added to Devin and indexed. Used via Slack, Linear/Jira tags, web app, with playbooks and MCP integrations such as Datadog, Sentry and Redshift.

## Worth knowing

Written by the vendor about its own product; the post gives no detail on review effort or failure rates.

## Evidence note

Vendor blog states weekly PR counts; screenshots, no independent repo
