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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00058 | $0.00267 |
| Opus 5.5 | $0.00023 | $0.00107 |
| Sonnet 5.5 | $0.00012 | $0.00053 |
| Haiku 4.5 | $0.00006 | $0.00027 |
Grade A, and why
component-source-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 1mo 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.
What it actually says
Component Source Router
Principle
A component source solves implementation cost; it does not define the final visual language.
Route in this order
- semantic native HTML/CSS when sufficient;
- accessible unstyled primitives for complex behavior;
- owned/source components when they save implementation time;
- animated/visual registries as inspiration or behavior prototypes;
- custom implementation when the signature interaction requires it.
Read references/catalog.md when choosing a source.
Before adopting an external component
Check:
- behavior fit;
- accessibility and keyboard model;
- framework/runtime fit;
- dependency cost and duplication;
- styling reset effort;
- responsive behavior;
- reduced-motion behavior;
- license/current documentation.
Integration rule
Strip generic surface styling, map to project tokens, rewrite content, adapt composition, audit states, and remove unused dependencies. If the imported component makes the page look like its registry, the integration is unfinished.
What ships with it
2 files 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.

component-source-router is a skill published in the GitHub repository Lrinvl1203/world-class-web-design-os (8 stars, last pushed 22d ago), licensed MIT. It adds 58 tokens to every session and 267 once invoked, about $0.0002 per session on Opus 5.5. 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.
