SKILL.md instructions

# camsnap

Use `camsnap` to grab snapshots, clips, or motion events from configured cameras.

Setup

- Config file: `~/.config/camsnap/config.yaml`
- Add camera: `camsnap add --name kitchen --host 192.168.0.10 --user user --pass pass`

Common commands

- Discover: `camsnap discover --info`
- Snapshot: `camsnap snap kitchen --out shot.jpg`
- Clip: `camsnap clip kitchen --dur 5s --out clip.mp4`
- Motion watch: `camsnap watch kitchen --threshold 0.2 --action '...'`
- Doctor: `camsnap doctor --probe`

Local webcams (macOS)

- List devices: `camsnap devices`
- Snapshot from a local camera: `camsnap snap --device 0 --out webcam.jpg`
- PTZ position and ranges: `camsnap ptz status --device 0`
- Move a gimbal camera: `camsnap ptz goto --device 0 --pan 45 --tilt -18`
- Also `camsnap ptz move` (relative deltas) and `camsnap ptz home`.

Notes

- Requires `ffmpeg` on PATH.
- Prefer a short test capture before longer clips.
- PTZ needs macOS Camera permission: these cameras only service UVC controls while streaming, so `camsnap` holds a capture session open for the operation.
- Motion commands verify the settled position and exit non-zero if the camera did not reach it. On-camera AI framing can override manual positioning; disable tracking if moves keep missing.
