# OpenVideo skill · v0.1.0

**Brand: OpenVideo** (always lead with this). MiniMax H3 is the model OpenVideo drives.

**Job:** use **OpenVideo** so an agent produces **good product video**, not a random diffusion
click. Quality comes from **prompt craft + correct mode + validated settings**, not secret samplers.

## 0. Paths (env-first)

Recommended sibling layout (any parent dir name; no machine-absolute paths):

```text
parent/
├── open-video/       # THIS product — CLI, backends, skills  ← work here
└── lab/              # ComfyUI + weights (not git)
```

| What | Path / env |
|---|---|
| **Product root (CLI, skills)** | `$OPEN_VIDEO_ROOT` (this checkout) |
| **Install / pull / run** | From product root: `./scripts/install.sh`, `python -m open_video …` |
| **Lab engine + weights** | `$OPEN_VIDEO_LAB` / `$H3_LAB` (sibling `lab/` with ComfyUI + `h3_models/`) |
| **Weights env** | `export OPEN_VIDEO_MODELS=$H3_LAB/h3_models` |
| **ComfyUI URL** | `export OPEN_VIDEO_COMFYUI=http://127.0.0.1:8188` (default) |

**Resolve product root** (never hardcode a machine path):

```bash
# Prefer env, else directory of this skill → repo root
export OPEN_VIDEO_ROOT="${OPEN_VIDEO_ROOT:-$(cd "$(dirname "$0")/../.." 2>/dev/null && pwd)}"
cd "$OPEN_VIDEO_ROOT"
```

Lab harness (same ComfyUI) when you keep a sibling runtime:

```bash
export OPEN_VIDEO_LAB="${OPEN_VIDEO_LAB:-$OPEN_VIDEO_ROOT/../lab}"
export H3_LAB="${H3_LAB:-$OPEN_VIDEO_LAB}"
export OPEN_VIDEO_MODELS="${OPEN_VIDEO_MODELS:-$H3_LAB/h3_models}"
```
