The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to install the ducklake extension within DuckDB and fetches example data from blobs.duckdb.org. These operations target the official infrastructure of the DuckDB project.
[INDIRECT_PROMPT_INJECTION]: The skill instructs the agent on how to ingest data from external sources, which is a standard feature of the database tool.
Ingestion points: Data is loaded into tables from external URLs and local paths (e.g., FROM 'https://...' in SKILL.md).
Boundary markers: None explicitly provided in the skill instructions.
Capability inventory: The skill uses DuckDB SQL capabilities to read/write files and perform maintenance tasks (detailed in SKILL.md and references/maintenance.md).
Sanitization: Relies on the underlying DuckDB engine's data parsing logic.
[COMMAND_EXECUTION]: Provides standard CLI examples for opening databases using the duckdb command-line interface.
[DATA_EXFILTRATION]: While the skill describes connecting to external PostgreSQL and SQLite catalogs, these are standard database operations for a lakehouse format and do not involve unauthorized data movement.
