Create Space Time Cube

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

Annotations already establish this is a non-read-only, non-idempotent, non-destructive, closed-world write. The description adds nothing behavioral beyond that — no mention of overwrite behavior when output_cube exists, no permission or licensing requirements, no error conditions.

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?

A single front-loaded sentence with no filler, so nothing is wasted. It is arguably too terse for an 11-parameter geoprocessing tool, but the structure itself is efficient.

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 complex 11-parameter, 5-required geoprocessing operation with zero schema descriptions, the description is far too thin. An output schema exists so return values need not be explained, but input handling, defaults, and prerequisites are all missing.

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?

Schema description coverage is 0% across 11 parameters, so the description must carry the full semantics burden. It only gestures at time/distance units, alignment, and summary fields, leaving the 5 required parameters (in_features, output_cube, time_field, time_step_interval, distance_interval) and optional ones like template_cube and reference_time undocumented.

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 names a specific verb (创建/create) and resource (.nc space-time cube) with its input (时空点/spatiotemporal points), so an agent can tell what the tool produces. It is clear but never contrasts itself with any sibling tool or explains what a space-time cube is for.

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?

There is no statement of when to use this versus alternatives, no prerequisites, and no exclusion criteria. It only lists constraints on the operation, not context for choosing it.

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