Risk Level: HIGH
Full Analysis
HIGH W007: Insecure credential handling detected in skill instructions.
- Insecure credential handling detected (high risk: 0.90). The prompt includes commands that embed plaintext secrets (e.g., fill @e2 "password123", set credentials user pass, set headers '{"X-Key":"v"}' and saving/loading auth.json), so an agent following it would likely need to output secret values verbatim, creating exfiltration risk.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 1.00). The skill's SKILL.md explicitly instructs the agent to open arbitrary URLs (agent-browser open ), snapshot and read page DOM/text (agent-browser snapshot, get text/html, eval), and interact with elements—i.e., it fetches and interprets untrusted public web content which can directly influence subsequent actions.
