dogfood

Systematically explore and test a web application to find bugs, UX issues, and other problems. Use when asked to "dogfood", "QA", "exploratory test", "find issues", "bug hunt", "test this app/site/platform", or review the quality of a web application. Produces a structured report with full reproduction evidence -- step-by-step screenshots, repro videos, and detailed repro steps for every issue -- so findings can be handed directly to the responsible teams.

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

Insecure credential handling detected (high risk: 1.00). The prompt explicitly instructs the agent to request and insert user credentials and OTPs into commands (e.g., agent-browser ... fill "{PASSWORD}"), which requires the LLM to handle and output secrets verbatim, creating an exfiltration risk.

Medium

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

Third-party content exposure detected (high risk: 0.90). The SKILL.md explicitly instructs the agent to open and systematically explore an arbitrary Target URL (e.g., "agent-browser --session {SESSION} open {TARGET_URL}" and use snapshot/read commands to read page content and drive navigation), so it fetches and interprets untrusted third‑party web content that can influence subsequent actions.
