Post-Processing Router

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

Routing Protocol

•Classify — Identify effect type from user request
•Match — Apply signal matching rules below
•Combine — Most production scenes need 2-3 skills together
•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)

code

postfx-composer → Pipeline architecture, effect ordering
postfx-bloom    → Basic glow effects

Cinematic Scene (3 skills)

code

postfx-composer → Pipeline setup, tone mapping
postfx-bloom    → Subtle glow on lights
postfx-effects  → Vignette, grain, color grading

Neon/Cyberpunk Aesthetic (2 skills)

code

postfx-bloom    → High-intensity selective bloom
postfx-effects  → Chromatic aberration, vignette

Custom Effect Development (1-2 skills)

code

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	-

Temporal Collapse Stack

code

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
