## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Bevy Horror (thin router)

Genre router. Domain work lives in the Bevy skills below.

## When to use

Load this for sanity or detection as your components, plus lighting and audio.

## ECS shape

- **Components** hold the genre's per-entity flags as plain data. This file does not name new engine types.
- **Resources** hold run-wide counters (score, wave index, seed) via bevy-data-resources.
- **Systems** read those components on `Update` or the fixed timestep from bevy-master. Order them with `.chain()` when a later system must see the result.
- **Schedule:** gameplay mode changes go through bevy-state-machines. This file registers only the sanity, suspicion, and light systems.

## Routing

- [bevy-3d-lighting](https://github.com/thedivergentai/Game-Dev-Agentic-Skills/blob/main/skills/bevy-3d-lighting/SKILL.md) - Darkness.
- [bevy-audio-systems](https://github.com/thedivergentai/Game-Dev-Agentic-Skills/blob/main/skills/bevy-audio-systems/SKILL.md) - Stingers.
- [bevy-ai-navigation](https://github.com/thedivergentai/Game-Dev-Agentic-Skills/blob/main/skills/bevy-ai-navigation/SKILL.md) - Stalker policy.
- [bevy-mechanic-secrets](https://github.com/thedivergentai/Game-Dev-Agentic-Skills/blob/main/skills/bevy-mechanic-secrets/SKILL.md) - Lore flags.

## Scope

Sanity, suspicion, and light energy live on components. Darkness, stingers, and stalker paths stay in the skills linked above.

| Call | Owner here | Leave to the linked skill |
| --- | --- | --- |
| Fear falls while the player is vulnerable | `Sanity` on `FixedUpdate` | A light or audio crate |
| The stalker has line of sight | `Stalker.sees_player` and `suspicion` | Pathfinding in bevy-ai-navigation |
| A held light spends energy | `LightCell.energy` | Spotlights in bevy-3d-lighting |
