Devin.

A task that can be accepted

Devin is convenient where verification of the result is already known. For example, the task specifies which request causes the error and which response is expected. The agent can read the project code, execute commands and check changes within the session. Prepare a playable input, the expected result and the test run command. This task is easier to understand whether the reason has been corrected or only the text of the message has changed.

In an unfamiliar repository, it is useful to limit the search area. Specify the service or directory where the error occurs, and separately name files that cannot be changed. If playback requires access keys to real systems, replace them with test data.

Reprocessing check

In this example, a handler receives the same notification twice and creates two records. Give the agent an anonymized event, the unique key schema, and the command to run the test locally. Ask it to show where repeat events go unchecked, then add a test with two identical requests. During review, check separately that two different events still work as before.

In the patch, see where uniqueness is defined. Protection only at the level of one process can skip simultaneous requests. If the test runs events sequentially, it confirms a particular scenario but leaves the competition question open.

Access to the environment

Connect the repository and configure the environment separately. The team decides what code and tools are available in the session. Before accepting the patch, review the changes, run the tests from a clean branch, and compare the behavior with the task requirements.

Suitable tasks

• Reproduce the reported error and prepare a patch
• Check the change in a separate branch
