+# Superadmin: Übungs-Anreicherung per KI
+
+Stand: 2026-05-23 · App 0.8.178
+
+## Zweck
+
+Plattform-weites Werkzeug für Superadmins, um Übungen (typisch `draft`, ohne Skills) **batchweise** per KI mit Fähigkeiten anzureichern und kontrolliert auf `in_review` zu setzen.
+
+Verbessert indirekt die Planungs-KI (`POST /api/planning/exercise-suggest`), die gegen Skill-Profile rankt — unvollständige `exercise_skills` führen dort zu Volltext-dominiertem Ranking.
+
+## UI
+
+- Route: `/admin/exercise-enrichment` (nur Superadmin)
+- Admin-Menü: „Übungs-Anreicherung“
+
+## API
+
+Prefix: `/api/admin/exercise-enrichment`
+
+| Methode | Pfad | Beschreibung |
+|---------|------|--------------|
+| GET | `/candidates` | Paginierte Kandidaten (Filter: status, visibility, focus_area, without_skills, with_ai_suggested_skills, include_club, search) |
+| POST | `/preview` | Dry-Run — `{ exercise_ids[], modes: { skills, summary }, merge_mode }` |
+| POST | `/apply` | `{ items: [{ exercise_id, merged_skills }], merge_mode, set_status }` |
+
+Auth: `require_auth` + `is_superadmin` — **kein** `TenantContext` (EXEMPT, siehe ACCESS_LAYER_ENDPOINT_AUDIT.md).
+
+## KI
+
+Wiederverwendet `run_exercise_form_ai_suggestion` → Prompts `exercise_skill_suggestions` (MVP Pflicht), optional `exercise_summary`. Skill-Katalog via `build_contextual_skills_catalog_block` / `ai_skill_retrieval_profiles`.
+
+## Merge-Modi (Skills)
+
+- `additive` (Default): manuelle Skills bleiben; KI ergänzt neue; bestehende `ai_suggested`-Links werden aktualisiert
+- `replace_ai_only`: nur `ai_suggested=true` entfernen, dann KI-Set anwenden
+- `replace_all`: alle Skills ersetzen (explizit)
+
+## Defaults
+
+- Kandidaten: **Status** primär (Default `draft`); Sichtbarkeit Default **`private`**, wählbar bis „Alle“
+- Skill-Merge Default: **`replace_all`** (alle Skills KI-neu, `ai_suggested=true` — unterscheidbar von manuell)
+- Nach Apply: `set_status=in_review` (nie automatisch `approved`)
+- Batch: keine Gesamtgrenze (bis 10.000 IDs); **Analyze** + explizite Nutzerbestätigung; HTTP-Chunks à 25/100
+
+## Inhalte (modular)
+
+| Modus | Prompt | Apply-Felder |
+|-------|--------|--------------|
+| Skills | `exercise_skill_suggestions` | `exercise_skills` inkl. Intensität, required/target_level, `ai_suggested` |
+| Summary | `exercise_summary` | `summary`, `summary_ai_generated=true` |
+| Anleitung | `exercise_instruction_rewrite` | `goal`, `execution`, `preparation`, `trainer_notes` |
+
+## API (ergänzt)
+
+| Methode | Pfad | Beschreibung |
+|---------|------|--------------|
+| GET | `/candidate-ids` | Alle IDs zum Filter (Select-all) |
+| POST | `/analyze` | `{ exercise_ids[], modes }` → Kosten-Schätzung vor Start |
+
+## Keine Migration
+
+Bestehende Spalte `exercise_skills.ai_suggested` reicht; kein Enrichment-Log in MVP.
+
+## Tests
+
+`backend/tests/test_exercise_enrichment_admin.py` — 403, Merge-Logik, Status draft→in_review.
