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 | $0.00101 | $0.01284 |
| Opus 5.5 | $0.00040 | $0.00514 |
| Sonnet 5.5 | $0.00020 | $0.00257 |
| Haiku 4.5 | $0.00010 | $0.00128 |
Grade A, and why
crazy-ecommerce-builder 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crazy Ecommerce Builder
Turn a short company brief into a coherent creative thesis, a custom image world, and a working ecommerce experience. Make the result surprising because it expresses the product truth—not because it uses random effects.
Required companion skills
Use the available sites-building skill for implementation and validation, imagegen for original raster assets, and sites-hosting for publishing unless the user asks to keep the site local. Read each selected skill before taking its actions. If one is unavailable, follow the closest local workflow and state the limitation briefly.
Inputs
Extract or infer:
- company or product name;
- what is sold and why it is meaningfully different;
- customer and price position;
- catalog size or representative products;
- brand personality, taboos, and desired level of visual risk;
- existing assets, copy, site, stack, and publishing preference.
Do not demand a complete brief. Ask at most two short questions only when a missing answer would materially change the business or creative direction. Otherwise make labeled assumptions and proceed. Treat supplied product facts, prices, claims, and materials as source of truth; never invent regulated, medical, sustainability, performance, or certification claims.
Workflow
1. Inspect and protect the workspace
Determine whether this is a new site or an existing project. Preserve the existing package manager, architecture, working features, user changes, and hosting configuration. Inspect the current product surface before editing. Do not replace a functioning project solely to use a preferred framework.
2. Write the creative thesis
Before designing, condense the brief into:
- Product tension — the surprising contradiction or transformation inside the product.
- Customer feeling — the emotion the first viewport should create.
- Visual world — one specific art-direction system with palette, type behavior, composition, photography, motion, and texture.
- Commerce spine — the shortest path from intrigue to product understanding to purchase.
- Signature device — one memorable motif tied to the product, such as a seam, split, orbit, tear, specimen label, thermal map, or impossible scale shift.
What ships with it
4 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.
