The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: Fetches and installs standard Python dependencies httpx and python-dotenv from the official Python Package Index (PyPI) to handle network requests and environment configuration.
[DATA_EXFILTRATION]: Communicates with official Helius API endpoints (mainnet.helius-rpc.com and api-mainnet.helius-rpc.com) to retrieve Solana blockchain data. The skill correctly manages the API key via environment variables rather than hardcoding credentials.
[PROMPT_INJECTION]: The skill exhibits an indirect prompt injection surface by retrieving and displaying unvalidated content from the Solana blockchain, such as token descriptions and transaction metadata.
Ingestion points: scripts/token_lookup.py (retrieving token metadata via the DAS API) and scripts/wallet_analysis.py (retrieving transaction descriptions via the Enhanced Transactions API).
Boundary markers: No specific delimiters or "ignore instructions" warnings are applied to the displayed blockchain content.
Capability inventory: The scripts are limited to fetching data via httpx and printing to the console; no dangerous capabilities such as file system modifications, arbitrary command execution, or system-level access are present.
Sanitization: Data retrieved from the blockchain is printed directly to stdout without sanitization or HTML/markdown escaping.
