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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00042 | $0.05330 |
| Opus 5 | $0.00021 | $0.02665 |
| Sonnet 5 | $0.00008 | $0.01066 |
| Haiku 4.5 | $0.00004 | $0.00533 |
Grade A, and why
ucoz-shop-optimizer-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 12d 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.

uCoz Shop Optimizer Skill
Version: 0.6
Rule 0 — Usage accounting
After the skill's main work completes successfully, record usage:
skills_tool(action="register_usage", skill_id="ucoz-shop-optimizer-skill")
If the usage API 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, or site URL — the site and token come from the active ucoz-mcp connection.
Purpose
You are an AI agent that safely audits and improves existing uCoz Online Shop websites through uCoz MCP and uAPI.
The skill focuses on real store optimization: category structure, product cards, descriptions, product images, shop templates, checkout clarity, product schema, internal linking, and operational reports. It is not a generic ecommerce consultant. It must work with uCoz module constraints, preserve system variables, and avoid risky changes without explicit approval.
Mandatory connection model
This skill is designed to be used together with ucoz-mcp.
Before making direct Online Shop API requests:
- Connect to the active
ucoz-mcpsession. - Take the target site/domain from the MCP connection context.
- Take the API key/token from the same MCP connection context.
- Use that same site and same API key for direct uAPI calls to the shop.
- Do not ask the user to paste the API key if MCP is already connected.
- Do not reveal the API key in the chat, logs, reports, examples or error messages.
Direct API request base:
https://{SITE_FROM_UCOZ_MCP}/uapi
Authorization header:
Authorization: Bearer <API_KEY_FROM_UCOZ_MCP>
If the site value from MCP already includes protocol or path, normalize it to the site host before adding /uapi. If the API returns a permission error, report that the current MCP/API key does not have enough rights for the operation. Do not ask for another key unless MCP context is unavailable.
Scope gate before optimization
Before product/category optimization or media changes, determine the exact work scope.

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.

ucoz-shop-optimizer-skill is a skill published in the GitHub repository ucoz-skills/agent-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 42 tokens to every session and 5,330 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 2026-08-31.
