description	Compara dos versiones de un curso (via git tags o commits), clasifica cada cambio, y reporta impacto en alumnos enrolados. Read-only — no modifica state. Use when user asks to "diff course", "compare versions", "comparar versiones", "qué cambió", "/course-diff".

Diff de Curso entre Versiones

Lee dos versiones de course.json desde git history y produce un reporte de diferencias clasificadas.

Inputs

course-slug (required)
v1 (required): versión vieja (tag git o commit, ej. v1.0.0, HEAD~5)
v2 (required): versión nueva (tag git o commit, ej. v2.0.0, HEAD)

Flujo

Paso 1 — Verificar git context

cd docs/instructional-design/courses/{slug}/
git log --oneline {v1}..{v2} -- course.json

Si no hay diff, mensaje al usuario "No hay cambios entre {v1} y {v2} en course.json".

Paso 2 — Extraer ambas versiones

git show {v1}:docs/instructional-design/courses/{slug}/course.json > /tmp/course-{v1}.json
git show {v2}:docs/instructional-design/courses/{slug}/course.json > /tmp/course-{v2}.json

Paso 3 — Despachar changelog-generator

Despachar ${CLAUDE_PLUGIN_ROOT}/agents/changelog-generator.md con ambos paths.

Recibir:

Classification global (major/minor/patch)
Lista de cambios clasificados individualmente
Impact analysis si MAJOR

Paso 4 — Detectar ID stability violations

Si el agent reporta ID changes inmutables: marcarlos como ERRORS críticos en el reporte (no solo "BREAKING" — son inválidos en el modelo cmi5).

Paso 5 — Generate diff-report.md

docs/instructional-design/courses/{slug}/diffs/diff-{v1}-to-{v2}.md:

# Course Diff: {course} {v1} → {v2}
**Generated**: {date}
**Classification**: MAJOR | MINOR | PATCH | NO_CHANGE

## ID Stability Errors (críticos si presentes)
- {if any}: estos IDs no debieron cambiar — rompen historial xAPI

## Impact Analysis (solo si MAJOR)
- N alumnos enrolados podrían verse afectados
- Migration path sugerido: ...

Sin gates — read-only, idempotente. Mostrar el path generado al usuario al final.

workbook-generate

DojoCodingLabs/instructional-design-toolkit

Interactive course workbook design system — turns a course's text classes into one standalone, accessible, interactive HTML explainer (a navigable document chunked by module, Articulate-Rise lesson model; stepped mode for screen-recording). Defines the curated component kit, the content-shape -> component mapping rules, the accessibility contract, and the consumer-spec (instruction-bundle-spec.yaml) consumption + graceful-degrade rules. Consumer plugins own the brand tokens and the component vocabulary via their `workbooks` spec section; this skill stays voice-neutral.
