Use when the session context is getting long or unwieldy during training, before manual compaction, or when a long tangent should be compressed — steers compaction so the curriculum survives and tangents shrink.

Use when a maintainer asks to generate, build, or create the training package/course/deliverable for the current project ("generate the training", "build the course for this repo", "/training-generator:generate") — runs the full analyze → design → assemble → validate → register workflow.
Use when a maintainer asks to regenerate, refresh, or update an existing training package after source changes ("regenerate the training", "the docs changed, update the course", "/training-generator:regenerate").
Use when a maintainer asks to validate, check, or verify a generated training package ("validate the training package", "/training-generator:validate") without regenerating it.
Use when the learner asks any question — about the current lesson, a later topic, their own use case, design rationale, comparisons with other tools, or anything else during the {{PROJECT_NAME}} course.
Use when the learner asks to start, begin, or continue the {{PROJECT_NAME}} training in any natural phrasing ("Let's start the training.", "Start the course.", "Continue my training.", "let's keep going") — conducts the interactive course from durable local progress.
Use when the current activity is an exercise, when the learner asks to try an exercise, needs a hint, wants their exercise work checked, or wants to skip an exercise.

Generic compaction can preserve chit-chat and destroy course state. This
skill applies instructor/compaction-policy.md instead.
Flush durable state first. Anything that must survive but exists only in conversation goes to disk now:
node scripts/progress.mjs complete-activity ...node scripts/progress.mjs add-question "..."node scripts/progress.mjs add-context --topic T --note NCompact with explicit instructions. Run /compact with instructions
drawn from the policy's priority list, for example:
Preserve: course identity and version, current module/lesson/activity, remaining learning objectives, established project facts, exercise state, learner-specific context, unresolved questions. Compress every tangent to one line. Discard conversational narrative. Output a briefing in the shape given by instructor/compaction-policy.md.
Re-ground from files afterwards. The SessionStart hook re-injects the
authoritative summary after compaction; verify against
node scripts/progress.mjs status and the current lesson file before
continuing to teach. Trust files over summarized memory.
Compaction is a resilience mechanism. The durable record is
state/progress.json; if compaction ever loses conversational nuance, the
course continues correctly from disk.
