The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions for setting up the chrome-devtools-mcp package using npx. This targets the official Chrome DevTools project resources, which is a well-known and trusted service.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to audit external websites, creating a surface for indirect prompt injection where a target site could contain instructions intended to influence the agent.
Ingestion points: The skill ingests untrusted data from external websites through tools such as navigate_page, list_network_requests, and take_snapshot as described in Phases 1 through 4 of the workflow in SKILL.md.
Boundary markers: The instructions do not define explicit delimiters or warnings to isolate external data retrieved from target websites from the agent's core instructions.
Capability inventory: The skill utilizes browser interaction capabilities, including page navigation, performance trace recording, network inspection, and accessibility tree snapshots.
Sanitization: There are no specific sanitization or filtering steps defined for processing data retrieved from the target page's DOM or network response headers.
