The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill connects to the Alpha Vantage API (alphavantage.co) to retrieve financial data. This is a well-known and established service for financial information.
[PROMPT_INJECTION]: The skill processes external data from news feeds and earnings transcripts, which represents an attack surface for indirect prompt injection.
Ingestion points: Market news and earnings call transcripts via the NEWS_SENTIMENT and EARNINGS_CALL_TRANSCRIPT endpoints as documented in references/intelligence.md.
Boundary markers: The code examples do not show the use of delimiters or instructions to prevent the agent from obeying instructions embedded in the external data.
Capability inventory: The skill utilizes the requests library in SKILL.md to perform network operations.
Sanitization: No explicit sanitization or filtering of the retrieved financial text is demonstrated in the examples.
