Full Analysis
  • [COMMAND_EXECUTION]: The skill primarily operates by invoking shell commands through the grimoire and polymarket CLI tools to query market data and manage orders.
  • [EXTERNAL_DOWNLOADS]: The skill requires the installation of the official Polymarket CLI from its GitHub repository using Homebrew (brew tap Polymarket/polymarket-cli), which is a well-known service in the prediction market space.
  • [REMOTE_CODE_EXECUTION]: Utilizes npx -y @grimoirelabs/cli to download and execute code from the npm registry at runtime, which allows the agent to run the latest version of the wrapper tool without manual installation.
  • [CREDENTIALS_UNSAFE]: The skill instructs the user to provide highly sensitive information, including POLYMARKET_PRIVATE_KEY and API credentials, through environment variables to facilitate blockchain transactions and authenticated API requests.
  • [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection, a surface where instructions embedded in external data (like market titles or event descriptions) could influence agent behavior.
  • Ingestion points: User-supplied parameters for the search-markets command (such as --query, --slug, --question, --event, --tag, --category, --league, and --sport) are passed to the external API, and the results are returned to the agent context.
  • Boundary markers: No explicit delimiters or instructions to ignore embedded commands within the market data are present in the skill definition.
  • Capability inventory: The skill possesses the ability to execute shell commands and perform sensitive financial operations (order placement and cancellation) on the Polygon blockchain.
  • Sanitization: There is no evidence of sanitization or validation of the market metadata fetched from the external Polymarket backend before it is interpreted by the agent.
