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 | $0.00049 | $0.01441 |
| Opus 5 | $0.00024 | $0.00720 |
| Sonnet 5 | $0.00010 | $0.00288 |
| Haiku 4.5 | $0.00005 | $0.00144 |
Grade A, and why
shader-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 8d 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.

Shader Router
Routes to 4 specialized GLSL shader skills based on task requirements.
Routing Protocol
- Classify — Identify what visual result is needed
- Match — Find skill(s) with highest signal match
- Combine — Most shaders need 2-3 skills together
- Load — Read matched SKILL.md files before implementation
Quick Route
Tier 1: Core (Always Consider)
| Task Type | Skill | Primary Signal Words |
|---|---|---|
| Writing shaders | shader-fundamentals |
GLSL, vertex, fragment, uniform, varying, coordinate |
| Organic patterns | shader-noise |
noise, procedural, terrain, clouds, turbulence, organic |
Tier 2: Specialized (Add When Needed)
| Task Type | Skill | Primary Signal Words |
|---|---|---|
| Shapes/geometry | shader-sdf |
shape, circle, box, boolean, union, morph, raymarch |
| Visual polish | shader-effects |
glow, bloom, chromatic, distortion, vignette, glitch |
Signal Matching Rules
Priority Order
When multiple signals present, resolve by priority:
- Explicit technique — "use simplex noise" →
shader-noise - Visual goal — "organic look" →
shader-noise - Shape need — "rounded rectangle" →
shader-sdf - Polish need — "add glow" →
shader-effects - Default — Start with
shader-fundamentals
Confidence Scoring
- High (3+ signals) — Route immediately
- Medium (1-2 signals) — Route with
shader-fundamentalsas base - Low (0 signals) — Ask: "What visual effect are you trying to achieve?"
Common Combinations
Procedural Texture (2 skills)
shader-fundamentals → Vertex/fragment setup, uniforms
shader-noise → Noise functions, FBM
Wiring: Fundamentals provides shader structure, noise generates patterns.
Stylized Shape (3 skills)
shader-fundamentals → Shader setup, UV handling
shader-sdf → Shape definition, boolean ops
shader-effects → Glow, outline, anti-aliasing
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.
- 8d ago First seen · 191 lines · 49 tokens per session scan A da1d423cf06d
shader-router is a skill published in the GitHub repository Bbeierle12/Skill-MCP-Claude (8 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 1,441 once invoked, about $0.0002 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 2026-09-03.
