Course 4.4 · Curriculum 2026.1
Running agents in parallel with worktrees
Run several agents at once without them overwriting each other. Isolation, merge discipline, and knowing when parallelism stops paying.

This course does not issue a certificate on its own. It counts toward the paths listed below, and those do.
01What you will learn
6 capabilities, stated as things you can do
Each one is what you should be able to do at the end, not what the course covers. If an outcome is not testable, it is not an outcome.
- Set up isolated working trees so two agents never touch the same files.
- Split work into tasks that genuinely do not overlap.
- Merge parallel results without losing work or shipping a silent conflict.
- Recognise the point where coordination costs more than the parallelism saves.
- Keep org-level side effects from colliding when two agents deploy.
- Review parallel output as one change rather than as three unrelated ones.

5 modules, 26 lessons
Every lesson shows its length and its type. A SCORM lesson looks like any other lesson, which is the point of ingesting packages rather than linking out to them.

Separate working trees, separate scratch orgs, separate everything an agent can write to.

Three agents produce one change. Reviewing it as three unrelated diffs misses the story that only exists across all of them.

Parallelism has a coordination cost. Past a certain point it is larger than the time it saves.

SCORM lessons report their own completion, so we treat it as telemetry. The assessment is what awards a certificate.
