higgsfield-soul-id
Train a Soul Character — a personalized model on a person's face that Higgsfield uses for identity-faithful image and video generation. Use when: "create my Soul", "train my face", "make my digital twin", "build me an avatar", "learn my appearance", "create a character of me", "set up identity for video", "I want my face in generated images". Chain: train Soul (one-time, returns reference_id) → use in higgsfield-generate via `--soul-id <id>` with models like `text2image_soul_v2` or `soul_cinematic`. NOT for: one-shot face swaps (use higgsfield-generate with --image), named-character / non-photo avatars (use higgsfield-generate with prompt).

Manual command
git clone https://github.com/higgsfield-ai/skills /tmp/skills && ln -s /tmp/skills/higgsfield-soul-id ~/.claude/skills/higgsfield-soul-idFrom README
Higgsfield Soul Character Train a face-faithful identity model. Reusable across all Soul-powered generations. Step 0 — Bootstrap Before any other command: If higgsfield is not on $PATH, it: If higgsfield account status fails with Session expired / Not authenticated, ask the user to run higgsfield auth login (interactive) and wait for confirmation. Soul training requires a paid plan (Basic+). If higgsfield account status shows free plan, tell the user before submitting. UX Rules Be concise. No raw IDs in chat. Just say "Soul ready" with a name reference. Detect language and respond in it. CLI flags stay English. Ask for the smallest set of inputs: name + photos. Pick a sensible model variant. Polling is silent — training takes minutes. Don't repeat status updates. Workflow Get name. One word, used for later reference. Ask if missing. Get photos. 5–20 face photos, varied angles and lighting. Local paths or already-uploaded IDs both work — --image accepts either. Pick variant.
