Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.01262 |
| Opus 5 | $0.00030 | $0.00631 |
| Sonnet 5 | $0.00012 | $0.00252 |
| Haiku 4.5 | $0.00006 | $0.00126 |
Grade A, and why
postfx-router scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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-composerfor 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
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 164 lines · 59 tokens per session scan A 734128272fd2
postfx-router is a skill published in the GitHub repository Bbeierle12/Skill-MCP-Claude (8 stars, last pushed yesterday), licensed MIT. It adds 59 tokens to every session and 1,262 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Exploit Flask/Werkzeug debugger exposure for traceback and SECRET leaks.
flask-expert
Expert-level Flask web development, REST APIs, extensions, and production deployment. Use when the user mentions Python, web framework, REST APIs, or Jinja2, or when the task involves Flask Fundamentals or Flask Extensions.
fast-dash
Build a Fast Dash web app from a Python function. Use when the user wants to turn a function into an interactive app, add a UI to an existing function, or build a dashboard / form / wizard. Fast Dash infers UI components from type hints, so a well-typed function becomes an app with one decorator.
