The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill facilitates the installation of the polars Python library (version 1.41.2). This is a well-established, reputable open-source library used for data manipulation and analysis.
[COMMAND_EXECUTION]: The documentation includes shell commands for environment setup and package installation using the uv tool, which is a common and legitimate practice in Python development.
[PROMPT_INJECTION]: The skill enables an attack surface for indirect prompt injection by providing tools to ingest data from external sources (CSV, Parquet, JSON, and databases).
Ingestion points: Data reading functions such as pl.read_csv, pl.scan_parquet, and pl.read_database documented in references/io_guide.md allow the agent to load content from external files and network locations.
Boundary markers: The provided code examples do not explicitly demonstrate the use of delimiters or 'ignore' instructions to isolate processed data from the agent's control logic.
Capability inventory: The skill allows the agent to perform extensive data transformations and analytical queries using the native Polars expression API.
Sanitization: The skill does not specifically address data sanitization for injection risks, relying instead on the strict schema enforcement and type system of the underlying library.
