Security audit
Security checks for vulnerabilities and agentic risk
The Square workflow is coherent, but fallback setup executes unverified downloaded code without a clear installation approval step.
Review and explicitly approve a pinned, verified CLI installation before allowing setup. Understand that Square customer operations pass through OOMOL, and retain the required confirmation for writes. Only SKILL.md was bundled; the remote installer and connector runtime were not available for inspection.
The only supplied behavior is fetching and executing an external installer, rather than interacting with Square. Dependency installation could be a supporting implementation detail, but nothing in this chunk establishes that the installer supports the declared Square functionality. The remote payload's downstream behavior cannot be determined from the supplied code.
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
- `create_customer` — Create a Square customer profile. [write]
- `get_customer` — Retrieve one Square customer profile by ID.
- `list_customers` — List Square customer profiles with cursor pagination.
- `list_locations` — List Square seller locations for the connected access token.
- `search_customers` — Search Square customer profiles with supported Square filters.
- `update_customer` — Update a Square customer profile by ID. [write]
Piping an HTTPS response directly into bash executes whatever the endpoint returns with the agent process's local permissions, without inspection or independent integrity verification. A compromised distribution endpoint could therefore compromise the local environment; the PowerShell installation example has the same risk, although there is no evidence that either endpoint is currently malicious.
oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):
curl -fsSL https://cli.oomol.com/install.sh | bash # macOS / Linux
On a missing-command error, the skill directs the agent to execute a downloaded installer without first explaining its effects or obtaining installation approval. This expands a Square data task into local code execution and system modification; the conditional setup trigger reduces exposure but does not establish user consent.
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.
- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
