vfx-water-ripple from summerengine/summer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add summerengine/summer/vfx-water-ripple@git:20261016.e9d6e70Pins git:20261016.e9d6e70 in mdr.lock. Pin the fingerprint instead.

Water-ripple effect: animated normal-distortion ripples on a water plane or Decal, set off by impacts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# water-ripple — Impact Ripples on a Water Plane Concentric expanding rings on a water surface, normal-distorted so the ripple actually refracts the reflection. The shader keeps a small ring buffer of (origin, time, amplitude) tuples and renders all of them simultaneously over a base water plane. GDScript exposes `add_ripple(world_pos, amplitude)` so any system (rain, footsteps, projectile impacts, fish) can spawn one with a single call. ## When to use - "Add ripples when the player walks through the puddle." - "Rain hitting the lake should make ripples." - "When the bullet hits the water, ripple." - "Fish jumping leaves ripples." - "Footsteps on the wet street should ripple." - A water plane already exists and looks too static. ## When NOT to use - The user wants the *whole* water surface to wave (Gerstner / FFT ocean) — that needs an ocean wave shader; this recipe adds impact ripples on top. - The user wants a 2D top-down ripple effect on a UI map — use `canvas_item` shader, not this `spatial` one. - The user wants splash particles flying upward on impact — pair this with `vfx-hit-spark` (recolor blue) for the droplets; this only handles the ring on the surface. …

How to install
mdr add summerengine/summer/vfx-water-ripple@sha256:6d78fd868137b497The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
