USDA FoodData Central API

Security checks across malware telemetry and agentic risk

Overview

This skill is a narrow USDA FoodData Central helper that uses a user-provided API key to search foods and display nutrition data.

Install only if you are comfortable storing a USDA FDC API key for OpenClaw. Keep ~/.openclaw/openclaw.json private, do not commit or share it, and rotate the key if it is exposed.

Finding
The skill invokes shell scripts and makes outbound API calls, but the manifest does not declare explicit permissions for shell or network access. This creates a transparency and policy-enforcement gap: a host system or reviewer may underestimate the skill’s capabilities, and future permission gating cannot reliably restrict it. In this context the behavior is expected for the skill’s purpose, but undeclared capabilities are still a real security weakness.
