| 1 | # /higgsfield-soul-id — Train a Reusable Face Identity |
| 2 | |
| 3 | Train a face-faithful Soul Character model. Reusable across all Soul-powered image and video generations in `higgsfield-generate`. |
| 4 | |
| 5 | ## When to use |
| 6 | |
| 7 | - User wants their face (or a specific person's face) in Higgsfield-generated images/videos |
| 8 | - "train my soul", "create soul character", "make a digital twin", "brand character training" |
| 9 | - Setting up a reusable identity before a campaign requiring consistent character appearance |
| 10 | - The user has 5–20 photos of a face and wants them persisted as a model reference |
| 11 | |
| 12 | **Route elsewhere if:** |
| 13 | - User just wants a one-shot image with a face reference → `higgsfield-generate` with `--image` |
| 14 | - User wants a fictional/non-photo avatar from a text description → `higgsfield-generate` with a prompt |
| 15 | |
| 16 | ## On Activation |
| 17 | |
| 18 | 1. Read `brand/visual-style.md` if present — check for brand character or persona notes. |
| 19 | 2. Ask for the name to assign to the Soul (one word, used for later reference). |
| 20 | 3. Ask for photos (5–20 face photos, local paths or upload UUIDs). |
| 21 | 4. Confirm plan tier: Soul training requires Basic+ plan. Check `higgsfield account status`. |
| 22 | |
| 23 | ## Optional dependency — Higgsfield account |
| 24 | |
| 25 | This skill requires the `@higgsfield/cli` binary and a Higgsfield account. |
| 26 | |
| 27 | **Without the CLI installed**, return a clear actionable error: |
| 28 | ``` |
| 29 | higgsfield CLI not found. Install with: |
| 30 | curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh |
| 31 | Then authenticate: |
| 32 | higgsfield auth login |
| 33 | ``` |
| 34 | |
| 35 | **Without an authed Higgsfield account**, the CLI itself surfaces the auth prompt — no special handling needed in the skill. |
| 36 | |
| 37 | **Fallback for image generation only:** if the user just needs a one-off image and doesn't have a Higgsfield account, route them to `image-gen` (Gemini, model `gemini-3.1-flash-image-preview`, free tier). Soul Character training has no fallback — it requires Higgsfield. |
| 38 | |
| 39 | ## Step 0 — Bootstrap |
| 40 | |
| 41 | Before any other command: |
| 42 | |
| 43 | 1. If `higgsfield` is not on `$PATH`, install it: |
| 44 | ```bash |
| 45 | curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh |
| 46 | ``` |
| 47 | 2. If `higgsfield account status` fails with `Session expired` / `Not authenticated`, ask the user to run `higgsfield auth login` (interactive) and wait for confirmation. |
| 48 | 3. Soul training requires a paid plan (Basic+). If `higgsfield account status` shows free plan, tell the user before submitting. |
| 49 | |
| 50 | ## UX Rules |
| 51 | |
| 52 | 1. Be concise. No raw IDs in chat. Just say "Soul ready" with a name reference. |
| 53 | 2. Detect language and respond in it. CLI flags stay English. |
| 54 | 3. Ask for the smallest set of inputs: name + photos. Pick a sensible model variant. |
| 55 | 4. Polling is silent — training takes minutes. Don't repeat status updates. |
| 56 | |
| 57 | ## Workflow |
| 58 | |
| 59 | 1. **Get name.** One word, used for later reference. Ask if missing. |
| 60 | 2. **Get photos.** 5–20 face photos, varied angles and lighting. Local paths or already-uploaded IDs both work — `--image` accepts either. |
| 61 | 3. **Pick variant.** |
| 62 | - `--soul-2` — for image generation (default) |
| 63 | - `--soul-cinematic` — for cinematic / video work |
| 64 | Choose based on user's stated downstream use. Default to `--soul-2`. |
| 65 | 4. **Submit.** |
| 66 | ```bash |
| 67 | higgsfield soul-id create --name "<name>" --soul-2 --image ./photo1.png --image ./photo2.png ... |
| 68 | higgsfield soul-id create --name "<name>" --soul-2 --image <upload_id> --image <upload_id> ... |
| 69 | ``` |
| 70 | CLI auto-uploads paths. Captures returned reference id. |
| 71 | 5. **Wait.** `higgsfield soul-id wait <id>`. Silent. Default timeout 30m. |
| 72 | 6. **Deliver.** "Soul `<name>` ready. Use in generate with `--soul-id <id>`." |
| 73 | 7. **Log to brand assets.** Append the soul reference_id to `brand/assets.md` so it's discoverable in future sessions without re-asking. |
| 74 | |
| 75 | ## Use the Soul |
| 76 | |
| 77 | Once trained, pass to `higgsfield-generate`: |
| 78 | |
| 79 | ```bash |
| 80 | higgsfield generate create text2image_soul_v2 --prompt "..." --soul-id <ref_id> --wait |
