procedural-gen SKILL.md skillA

procedural-gen from ukanwat/overtime is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add ukanwat/overtime/procedural-gen@git:20260812.5b73825

Pins git:20260812.5b73825 in mdr.lock. Pin the fingerprint instead.

Generate game content procedurally — seeded deterministic RNG, value/Perlin/ Simplex noise for terrain and heightmaps, grid dungeon generation (rooms + corridors, BSP, random walk), and weighted loot/drop tables. Engine-neutral algorithms. Use when the user mentions procedural generation, perlin/simplex noise, random seed, dungeon generator, heightmap/terrain, or loot tables.

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

# Procedural generation

Generate levels, terrain, and loot from compact rules and a seed. The throughline
of good procgen is **determinism**: a single seed reproduces the same world, so
bugs are repeatable and players can share seeds. This skill owns the core
algorithms — noise, seeded RNG, dungeon layout, weighted tables; genres like
`roguelike` and `survival-crafting` consume it.

## When to use

- Use to generate maps, dungeons, terrain heightmaps, item drops, or any content
  you do not want to author by hand.
- Use when results must be **reproducible from a seed** (debugging, daily
  challenges, shareable worlds).
- Use to pick weighted random outcomes (loot rarity, spawn tables).

**When *not* to use:** for the engine's tile API to *paint* the result, use
`godot-tilemap` or `unity-tilemap-2d`. For routing AI through the generated map,
use `game-ai`. For carefully hand-paced levels, use `level-design` — procgen and
authored design are complementary, not interchangeable.

## Core workflow

1. **Own your randomness.** Create one seeded RNG instance and pass it
   everywhere. Never call the global/static random in generation code — it makes

How to install

The exact contents, by fingerprint

mdr add ukanwat/overtime/procedural-gen@sha256:f9a35b07f9963493

The line at the top of this page pins the label git:20260812.5b73825, 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.
