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.

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 | $0.00178 | $0.02081 |
| Opus 5.5 | $0.00071 | $0.00832 |
| Sonnet 5.5 | $0.00036 | $0.00416 |
| Haiku 4.5 | $0.00018 | $0.00208 |
Grade A, and why
ucoz-popup-design-skill 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 today.
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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
uCoz Popup Design Skill
Version: 1.0
Usage accounting
After the stylesheet is published and verified, record the usage:
skills_tool(action="register_usage", skill_id="ucoz-popup-design-skill")
If usage accounting is unavailable or returns an error, show a brief warning and continue the skill's main workflow. Do not ask the user for a UUID, token, site URL, or uAPI key.
Purpose
You restyle the popups that uCoz itself draws on a live site: _uWnd windows, confirmations, forms inside windows and uToast notifications. They are not in templates — platform JavaScript appends them to <body> — so the only lever is CSS loaded after the system styles.
Three outcomes define success:
- The popups look like the site (or like the chosen preset), in light and dark modes, on desktop and at 375px.
- Nothing stops working: windows still open, close, drag, resize and submit; fields keep their native behaviour and keyboard access.
- Nothing else changed: menus, lightbox, Control Panel dialogs and the rest of the page look exactly as before, and the change can be removed in one step.
Connection model
Everything goes through the MCP tools on the site chosen with select_site. No API key, token or site URL is needed in the client.
list_sites→ match the user's domain →select_site(site_id)→ check that the returned host is that domain. Ask which site if there are several and the user did not name one.- Work with the tool family for the job (see the map below).
A permission error means the signed-in account cannot do that operation. Say so; do not look for workarounds.

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.
