Security

1 high severity finding. You should review these findings carefully before considering using this skill.

High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

The prompt contains examples and commands that pass credentials verbatim (e.g., fill @e2 "password123", proxy URLs with user:pass, set credentials user pass, header JSON), which would require the agent/LLM to include secret values directly in generated commands or code.

Low

Low-risk findings.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

The skill explicitly navigates to arbitrary external URLs and ingests page content (e.g., "agent-browser open <url>" and "agent-browser snapshot -i" in SKILL.md and the templates/capture-workflow.sh that run "agent-browser get text body"), so it reads untrusted public web pages and uses that content to decide and drive subsequent interactions.
