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

With no annotations, the description must disclose behavior. It mentions reading inputs and writing an output feature class, but does not discuss permissions, processing limitations, or the fact that overwrite behavior is controlled via a parameter. Adequate but not comprehensive.

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?

Three sentences, front-loaded with core function, then use cases, then process. No wasted words. Excellent conciseness.

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?

The description covers the high-level workflow and use cases. With an output schema present (not shown but indicated), the lack of return value details is acceptable. Slightly incomplete regarding output attribute structure, but adequate.

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?

The input schema already has detailed parameter descriptions (paths, overwrite, keep_all_polygons). The tool description adds no extra semantic value beyond stating the tool's purpose. Schema coverage is high, so baseline 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 'summarize' and the resource 'features within polygon areas', with specific examples of use cases. However, it does not explicitly differentiate from sibling tools like intersect_features or dissolve_features, which also operate on polygon boundaries.

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?

The description includes usage examples (administrative zones, grid cells, etc.), implying when to use it, but lacks explicit guidance on when not to use it or alternatives among many spatial sibling tools.

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