+# Discovery Checklist
+
+## Quick Discovery
+
+Run the discovery script to get all available models:
+
+```bash
+node .claude/skills/partner-providers-eachlabs/discover-models.mjs
+```
+
+This outputs a minimal JSON array sorted by `output_type`:
+
+```json
+[
+  { "slug": "flux-2-pro", "title": "Flux 2 Pro", "output_type": "image" },
+  { "slug": "kling-v2-6-pro-text-to-video", "title": "Kling | v2.6 | Pro | Text to Video", "output_type": "video" }
+]
+```
+
+## Workflow
+
+1. **Run the script** to get current API models
+2. **Read `specs/providers/eachlabs/providers.md`** to see what's tracked
+3. **Compare** the lists to identify:
+   - New models (in API but not in providers.md)
+   - Removed models (in providers.md but not in API)
+4. **Report findings** to user with recommendations
+5. **Update providers.md** with new models after user approval
+
+## Output Types
+
+| output_type | Meaning |
+|-------------|---------|
+| `image` | Single image output |
+| `array` | Multiple images (batch) |
+| `video` | Video output |
+| `audio` | Audio output |
+| `text` | Text output |
+| `object` | Structured data |
+| `code` | Training/code output |
+
+## Capability Detection
+
+Determine capability from slug patterns:
+
+| Pattern in slug | Capability |
+|-----------------|------------|
+| `text-to-video` | t2v |
+| `image-to-video` | i2v |
+| `text-to-image` | t2i |
+| `-edit`, `-remix` | i2i |
+| `reference-to-` | i2i or i2v |
+
+## Notes
+
+- No authentication required for the models API
+- The script fetches up to 500 models
+- Full model details (including `request_schema`) available via: `GET https://api.eachlabs.ai/v1/model?slug=<slug>`
