# postfx-router — postfx-router intelligently directs Claude's post-processing requests to specialized skills based on the effect type being applied. This routing layer simplifies effect management by matching incoming requests with the appropriate handler, reducing manual configuration and improving workflow efficiency in MCP-based systems.

# Post-Processing Router

Routes to 3 specialized skills based on post-processing requirements.

## Routing Protocol

1. **Classify** — Identify effect type from user request
2. **Match** — Apply signal matching rules below
3. **Combine** — Most production scenes need 2-3 skills together
4. **Load** — Read matched SKILL.md files before implementation

## Quick Route

### Tier 1: Core (Start Here)
| Need | Skill | Signals |
|------|-------|---------|
| Pipeline setup, effect ordering | `postfx-composer` | EffectComposer, setup, pipeline, render target, custom pass, multi-pass |
| Glow, luminance effects | `postfx-bloom` | bloom, glow, neon, emissive, luminance, UnrealBloom, selective bloom |
| Cinematic polish, color | `postfx-effects` | vignette, chromatic, DOF, grain, color grade, LUT, aberration |

## Signal Matching

### Primary Signals

**postfx-composer** (always start here for new projects):
- "set up post-processing"
- "configure effect pipeline"
- "create custom effect/pass"
- "render targets", "effect ordering"

**postfx-bloom**:
- "bloom", "glow", "luminance", "neon", "emissive"
- "selective bloom", "object glow", "UnrealBloomPass"

**postfx-effects**:
- "chromatic aberration", "vignette", "depth of field", "DOF"
- "film grain", "noise", "color grading", "LUT", "tone mapping"
- "scanlines", "CRT", "god rays"

### Confidence Scoring

- **High (3+ signals)** — Route directly to matched skill
- **Medium (1-2 signals)** — Route with composer as foundation
- **Low (0 signals)** — Start with `postfx-composer` for setup

## Common Combinations

### Basic Post-Processing Setup (2 skills)
```
postfx-composer → Pipeline architecture, effect ordering
postfx-bloom    → Basic glow effects
```

### Cinematic Scene (3 skills)
```
postfx-composer → Pipeline setup, tone mapping
postfx-bloom    → Subtle glow on lights
postfx-effects  → Vignette, grain, color grading
```

### Neon/Cyberpunk Aesthetic (2 skills)
```
postfx-bloom    → High-intensity selective bloom
postfx-effects  → Chromatic aberration, vignette
```

### Custom Effect Development (1-2 skills)
```
postfx-composer → Custom Effect class, shader writing
postfx-effects  → Reference existing effects
```

## Decision Table

| Effect Type | Complexity | Primary Skill | Supporting Skill |
|-------------|------------|---------------|------------------|
| Glow/bloom only | Simple | bloom | composer |
| Cinematic look | Medium | effects | composer + bloom |
| Custom effect | Complex | composer | - |
| Selective bloom | Medium | bloom | composer |
| Color grading | Simple | effects | composer |
| Full production | Complex | All three | - |

## Effect Categories

### Lighting Effects → postfx-bloom
- Bloom/glow, selective bloom, emissive enhancement, HDR luminance

### Camera Effects → postfx-effects
- Chromatic aberration, vignette, depth of field, lens distortion

### Color Effects → postfx-effects
- Tone mapping, color grading, LUT, hue/saturation

### Texture Effects → postfx-effects
- Film grain, noise, scanlines, CRT

### Architecture → postfx-composer
- EffectComposer setup, effect ordering, custom effects, render targets

## Integration with Other Domains

### With R3F (r3f-*)
```
r3f-fundamentals → Scene setup
postfx-composer  → Effect pipeline
postfx-bloom     → Object glow
```

### With Shaders (shaders-*)
```
shaders-glsl     → Custom effect shader code
postfx-composer  → Wrap in Effect class
```

### With Particles (particles-*)
```
particles-systems → Particle emitters
postfx-bloom      → Particle glow
postfx-effects    → Atmosphere
```

### With Audio (audio-*)
```
audio-analysis    → Frequency data
postfx-bloom      → Audio-reactive bloom
postfx-effects    → Audio-reactive aberration
```

## Quick Reference

| Effect | Skill |
|--------|-------|
| Bloom | `postfx-bloom` |
| Selective Bloom | `postfx-bloom` |
| Vignette | `postfx-effects` |
| Chromatic Aberration | `postfx-effects` |
| Depth of Field | `postfx-effects` |
| Film Grain/Noise | `postfx-effects` |
| Color Grading | `postfx-effects` |
| LUT | `postfx-effects` |
| Tone Mapping | `postfx-effects` |
| Custom Effects | `postfx-composer` |
| Render Targets | `postfx-composer` |

## Temporal Collapse Stack

```
postfx-composer → HDR pipeline, tone mapping, adaptive quality
postfx-bloom    → Cosmic glow on digits, particles, UI
postfx-effects  → Vignette (void edge), subtle chromatic, grain
```

## Fallback Behavior

- **No framework context** → Assume @react-three/postprocessing
- **Unclear effect type** → Start with `postfx-composer` + `postfx-bloom`
- **Performance concerns** → Prioritize `postfx-composer` optimization patterns
