Get Platform Statistics

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

The description adds valuable context beyond annotations: it specifies the tool is for 'public' statistics and 'No authentication required,' which aren't covered by the existing annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint). However, it doesn't mention rate limits, response format, or data freshness, leaving some behavioral aspects unspecified.

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, efficient sentence that front-loads the purpose ('Get public platform statistics') and includes essential usage guidance ('No authentication required'). Every word serves a clear purpose with zero waste.

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?

Given the tool's simplicity (0 parameters, no output schema) and rich annotations, the description is mostly complete. It covers purpose, public access, and authentication status. However, without an output schema, it could briefly mention the return format (e.g., 'returns counts as numbers') for full 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?

With 0 parameters and 100% schema description coverage, the baseline would be 4. The description appropriately notes there are no parameters to specify, aligning with the empty input schema, and adds context about the tool's public nature.

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 specific action ('Get public platform statistics') and enumerates the exact resources returned ('total objects, templates, and wallets'). It distinguishes itself from sibling tools by emphasizing its public nature and lack of authentication, unlike most other tools that require authentication.

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 explicitly states 'No authentication required,' providing clear guidance on when to use this tool versus authentication-required alternatives. It implicitly suggests this is for public data access, contrasting with most sibling tools that likely require authentication.

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