The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructs the user or agent to install the fred-pp-cli binary using npx -y @mvanhorn/printing-press-library or go install github.com/mvanhorn/printing-press-library/library/other/fred/cmd/fred-pp-cli@latest. These resources are hosted on GitHub and NPM under the author's organization.
[COMMAND_EXECUTION]: The primary function of the skill is to execute the fred-pp-cli binary with various arguments to interact with the FRED API and manage a local SQLite database.
[DATA_EXFILTRATION]: The tool includes a --deliver webhook:<url> flag which allows the command output to be POSTed to any arbitrary external URL. Additionally, a feedback feature can be configured via environment variables (FRED_FEEDBACK_ENDPOINT) to send local notes to a remote server.
[INDIRECT_PROMPT_INJECTION]: The skill processes time-series data and metadata fetched from the external FRED API, which serves as an untrusted data source.
Ingestion points: Data is ingested via fred-pp-cli series observations, series search, and other API-connected subcommands (SKILL.md).
Boundary markers: None identified in the prompt instructions for the agent.
Capability inventory: The tool can write to the local filesystem (--deliver file:<path>) and perform network POST requests (--deliver webhook:<url>).
Sanitization: No specific sanitization or validation of the API data is mentioned before it is processed or displayed by the agent.
