agent-tool-builder
Tools are how AI agents interact with the world. A well-designed tool is the difference between an agent that works and one that hallucinates, fails silently, or costs 10x more tokens than necessary. This skill covers tool design from schema to error handling.

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: 0.80). The SKILL.md explicitly includes tool examples that fetch and ingest open web content (e.g., the Python "search_web" beta_tool example and MCP/tool-runner snippets that call external APIs like weather_api.fetch and fetchWeather), showing the agent is expected to read and act on untrusted public web/search results as part of its tool workflow.
