Day 27

Task Coordination

Aggregate results, handle failures, and build reliable parallel pipelines.

0 / 5 tasks

Merge strategies

After parallel agents finish, you need a merge step. For code generation, this might mean: checking imports don't conflict, ensuring naming is consistent, and running the full test suite to catch integration issues. Always have a human review the merge before committing.

Practice Tasks

0 / 5

Handle a failed subagent hard

Intentionally give one subagent an impossible task. Observe how the coordinator handles the failure.

Merge conflicting outputs hard

Have two agents generate different implementations. Have a third agent review both and choose the best.

Build a verification agent hard

After parallel generation, spawn a dedicated agent to verify consistency across all outputs.

Prioritize results medium

When agents return different quality results, have Claude rank and select the best outputs.

Parallel test pipeline hard

Split your test suite across parallel agents. Each runs a subset. Aggregate the results.
