count_browser_versions

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

Description only states 'Counts' and reporting purpose. With no annotations, it does not disclose authorization needs, rate limits, or behavior on no results. However, the operation is a simple read, so minimal disclosure is acceptable.

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?

Two sentences with no redundancy. Front-loaded with action verb. Every word contributes to purpose and usage.

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 only two optional parameters and existence of output schema, description adequately covers context. No missing information for this simple counting tool.

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 covers 100% of parameters with descriptions. Description adds no extra meaning beyond what schema provides, resulting in baseline score.

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?

Description clearly states it counts Chrome browser versions reported by managed devices. Verb 'counts' and resource 'Chrome browser versions' are specific. No sibling tool performs similar counting, so differentiation is inherent.

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?

Explicitly mentions use for auditing and reporting on distribution across organization or specific OU. Provides clear context but lacks explicit when-not-to-use or alternatives, though none are present.

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