mlava/agent-ready-cli
Use the Agent Ready (agent-ready.dev) command-line client to scan any public URL for AI agent-readability against the Vercel Agent Readability Spec, the llmstxt.org standard, and agent-protocol manifests (MCP server cards, A2A, agents.json, agent-permissions.json, UCP, x402, NLWeb). Activates for "scan this site with the agent-ready CLI", "run agent-ready scan {URL} in the terminal", "agent-ready get {id}", "agent-ready list", "agent-ready ask {question}", or any time the user wants a one-command terminal scan with no fetch wiring and no MCP install. Pick this skill when the agent can run shell commands. For raw HTTP, use the `agent-ready-api` skill; for MCP-native tool calls, use `agent-ready-mcp`.

2 low severity findings. Worth noting, but not necessarily harmful.
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
SKILL.md Step 3 (“agent-ready scan {URL}”) causes the service to crawl and then the CLI outputs scraped page text (titles/headings/llms.txt/AGENTS.md/check messages) that is outsider-authored, making indirect prompt-injection text readable at runtime via the target URL.

domain · 4 sites
The plugin fetches content from agent-ready.dev at runtime; that service crawls a user-specified target URL and returns scraped text (titles, headings, llms.txt, AGENTS.md bodies) which the agent reads back, creating an indirect prompt-injection surface.

W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill instructs running npx/npm which fetches and executes remote package code (agent-ready-scanner) at runtime — see the npm package URL: https://www.npmjs.com/package/agent-ready-scanner
