Course 06 of 10
Agent patterns
Anthropic's Building Effective Agents draws one line — workflows, where code decides the route, and agents, where the model does — and names five patterns on the workflow side. This course implements all of them as plainly as possible and runs them against the same tasks, because the hard part is not understanding a pattern but knowing which failure each one fixes, and whether that fix is worth what it costs.

Workflows
- 02Prompt chainingFixed sequential steps, with a gate written in code between them.11 min
- 03RoutingClassify the input, then hand it to a prompt built for that class.11 min
- 04ParallelisationSectioning and voting, and the difference between wall-clock and cost.12 min
- 05Orchestrator-workersWhen the sub-tasks cannot be known until you have seen the input.12 min
- 06Evaluator-optimiserGenerate, grade, feed back — and when the loop is worth its cost.11 min
