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

No annotations are provided, so the description carries the burden. It does disclose the basic behavior of returning aggregate counts, which implies a read-only operation, but it does not describe the return format or explicitly confirm non-mutating behavior. This is minimal but not misleading.

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, tightly written sentence with the verb and resource front-loaded. Every word adds value and there is no filler.

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 zero-parameter stats tool, the description lists the main output categories (total boards, families, topologies), which is mostly sufficient. However, there is no output schema, so a note about the return format (e.g., a single object with these counts) would improve completeness.

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 tool has zero parameters, so the description has no parameters to explain. A baseline of 4 is appropriate because no parameter documentation is needed.

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 uses a specific verb ('Get statistics') and names the resource ('board gallery') with concrete contents (total boards, families, topologies). This clearly distinguishes it from sibling tools like board_gallery_get and board_gallery_search.

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 use case is implied by the word 'statistics' — an agent would know to use this when aggregate counts are needed. However, there is no explicit guidance about when to prefer this over get/search variants or similar stats tools for other galleries.

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