The Agent Skills Directory

[COMMAND_EXECUTION]: The skill invokes a local Python script harness/scripts/web-crawl.py to handle web fetching, markdown conversion, and self-testing. This is a standard execution pattern for skill-specific logic.
[EXTERNAL_DOWNLOADS]: The skill is designed to fetch content from external URLs using the urllib library in its builtin backend. It also references well-known external services like Firecrawl and Crawl4AI for advanced functionality.
[PROMPT_INJECTION]: The skill processes untrusted data from the web, which introduces an indirect prompt injection surface.
Ingestion points: The fetch command ingests content from arbitrary external URLs, and the md command processes local HTML files.
Boundary markers: The skill encourages distilling content into markdown to reduce token usage and noise, which acts as a structural boundary, though explicit instructions to ignore embedded commands are not mentioned.
Capability inventory: The skill executes a local Python script and has the ability to write distilled content to the local file system (e.g., the raw/ directory).
Sanitization: The builtin backend uses regex to convert HTML to markdown, which naturally strips out executable tags like <script> and <object>, providing a layer of sanitization for the ingested content.
