How Devin marks a commit
Detection looks for any one of these signals. A commit needs only one to be attributed.
| Signal | Pattern |
|---|---|
| Co-author trailer | Co-Authored-By: Devin <[email protected]> |
| Commit author | devin-ai-integration[bot] |
Example
Author: devin-ai-integration[bot]
Add pagination to the rankings endpoint
Devin is an autonomous agent that works a task end to end and opens a pull request. Its commits carry a deterministic GitHub App author name and, where a person co-authored, a trailer under an address Cognition controls.
Devin is the clearest case of a general limitation: when an agent commits under its own identity, the commit attributes to the tool, not to the engineer who scoped, reviewed and merged the work. Those commits raise the tool’s totals and the repository’s, and never a person’s rank.
What detection misses
- Devin opens pull requests under its own identity, so the human who directed the work is not credited in these counts.
- Sessions that end without a merged branch leave nothing in history.
