Youdo Business

Security checks for vulnerabilities and agentic risk

Overview

This is an instruction-only YouDo Business API reference; it covers sensitive business actions, but those actions are disclosed and fit the stated purpose.

Install only if you want an agent to help with YouDo Business API operations. Use least-privilege credentials, avoid exposing private keys or JWTs in prompts/logs, prefer sandbox testing, verify IDs, amounts, and webhook URLs, and require explicit confirmation before payments, invoices, employee/project changes, agreement changes, document access, or webhook modifications.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The skill includes detailed instructions for JWT authentication and RS256 request signing, including issuer/company identifiers and signed payment flows, but provides no warning about protecting private keys, bearer tokens, or sensitive company/account data sent to the external API. In an agent setting, this can encourage unsafe handling of credentials or inadvertent transmission of secrets and business data without user awareness.
