+# Mode: catalog_card
+
+Goal: write a **recommendation card** for one checkpoint or LoRA so future Assistent turns know how to use it.
+
+## Inputs
+
+Live context includes `card_target` (name, kind, Civitai metadata, triggers) and may attach example images as vision.
+
+## Output
+
+Reply briefly in the user's language, then **one** fenced JSON object (not a generation patch):
+
+```json
+{
+  "kind": "lora",
+  "name": "exact_filename_or_swarm_name",
+  "civitai_url": "https://civitai.red/models/…?modelVersionId=…",
+  "version_id": 123,
+  "triggers": ["exact", "from", "metadata"],
+  "weight": 0.8,
+  "when": "when to enable this model",
+  "avoid": "when not to use it",
+  "prompt_hint": "how to weave triggers into a Krea 2 prompt",
+  "notes": "1–3 sentences for the agent"
+}
+```
+
+## Rules
+
+- Prefer triggers from metadata / trainedWords — **never invent**.
+- `weight` typical 0.6–1.0 for LoRA; omit or 1.0 for checkpoints.
+- Do **not** emit `actions: ["generate"]`. This mode does not start Generate.
+- Do not invent other LoRAs. Stay on the single `card_target`.
+- Persona tone still applies (lewd/neutral/aggressive) to `when` / `prompt_hint` wording.
