The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill fetches stock price data from well-known financial services including Yahoo Finance (query1.finance.yahoo.com) and Stooq (stooq.com). These network operations are limited to retrieving delayed market quotes in JSON and CSV formats.
[INDIRECT_PROMPT_INJECTION]: The skill represents a potential surface for indirect prompt injection because it ingests data from external websites.
Ingestion points: Data is fetched via urllib.request in alerts.py from external quote providers.
Boundary markers: The tool uses structured labels like ALERT and formatted tables to delimit output, providing some context to the agent.
Capability inventory: The skill has the ability to read and write local JSON files (trader/alerts.json, trader/prices.json) and make network GET requests.
Sanitization: The script performs specific parsing of JSON and CSV data, extracting only numeric price values and metadata, which significantly limits the risk of the LLM interpreting fetched data as instructions.
