read_file_gpd

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the burden. It describes a read operation with no side effects, which is appropriate, but it doesn't elaborate on what 'stats' are returned or any limitations (e.g., file size, supported formats). The presence of an output schema partially mitigates this, but the description adds limited behavioral detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no fluff. It is concise and efficient, though it could be slightly more informative without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with an output schema, the description is mostly adequate but lacks details about the nature of the stats and data preview. It does not list supported file formats or handling of errors. The presence of many sibling tools suggests more context could help disambiguate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Only one parameter 'file_path' with a string type. Schema description coverage is 0%, so the description must compensate. It adds the context that the file is geospatial, but does not clarify allowed formats, path conventions, or that the function returns stats and a preview. Given the simplicity of the parameter, a score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'reads' and the resource 'geospatial file' and mentions returning 'stats and a data preview'. It distinguishes itself from sibling tools like 'write_file_gpd' by focusing on reading, but does not explicitly contrast with other read-like tools such as 'metadata_raster'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidelines are provided. The description does not specify when to use this tool over alternatives, such as 'metadata_raster' or 'get_geometry_type', nor does it mention prerequisites or context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
