The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill fetches documentation from the official FFmpeg project website.
Evidence: The script scripts/ffdocs.py contains a hardcoded BASE URL pointing to https://ffmpeg.org and uses urllib.request to retrieve content.
[COMMAND_EXECUTION]: Instructs the agent to execute a local Python script for documentation lookup and management.
Evidence: SKILL.md contains multiple examples demonstrating how to use uv run to execute scripts/ffdocs.py for search, fetch, and indexing tasks.
[PROMPT_INJECTION]: The skill ingests data from an external website, which creates an indirect prompt injection surface.
Evidence: The fetch and search commands in scripts/ffdocs.py provide external documentation content to the agent.
Ingestion points: scripts/ffdocs.py reads HTML content from ffmpeg.org manually.
Boundary markers: The script provides structure by identifying headings and anchor IDs in the output.
Capability inventory: The skill facilitates network read operations, local file writes for caching, and script execution.
Sanitization: The script uses a custom TextExtractor class to parse HTML, explicitly skipping <script>, <style>, <nav>, and <footer> tags to provide clean text to the agent.
