A free static scan against the OWASP Agentic Skills Top 10 found no risk patterns in Sales Square Online’s SKILL.md — no data-exfiltration, prompt-injection, or unexpected-execution signatures. The full security scan is below.

Installing & verifying

Installing Sales Square Online writes its SKILL.md to ~/.claude/skills/sales-square-online/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — sales-square-online should appear by name.

From the source SKILL.md

Square Online is the online store inside the Square ecosystem — a free-to-start storefront that shares one catalog, inventory, customer directory, and order book with Square POS. You don't automate the site builder (that's UI-only); you automate the commerce layer with the standard Square APIs (Catalog, Orders, Inventory, Payments/Checkout) plus webhooks, OAuth, and the official Square MCP server. This skill covers that integration surface and the pain points — POS↔online inventory sync, processing-fee math, plan gates — that trip people up.

What this skill does

Sales Square Online is a community-contributed Claude Code skill in the sales-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sales-square-online/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when Square Online inventory won't sync with POS or items oversell, wiring Square orders or catalog into a CRM or data warehouse via the API, a Square webhook fails HMAC signature verification, your Square OAuth token expired after 30 days, choosing a Square Online plan (Free vs Plus vs Premium) or weighing the 3.3%+30¢ online fee against upgrading, setting up the Square MCP server in Claude or Cursor, or comparing Square Online vs Shopify/Wix/Squarespace/Ecwid for a retail-plus-online seller.
