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

With no annotations, the description carries the full burden of behavioral disclosure. 'Show' implies a read-only operation, but the description does not explicitly state that it is safe, what permissions are required, or what side effects (if any) exist. It also does not explain what 'coverage' entails beyond the three categories.

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 sentence, front-loaded with the verb and resource, and contains no filler or redundant information. It is appropriately concise.

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 tool is simple with no parameters and no output schema, so the description should compensate by explaining the nature of the output. While it mentions the three coverage areas, it does not clarify what 'coverage' means (e.g., a list, counts, booleans) or what the return format looks like, leaving some ambiguity.

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 is empty with zero parameters, so the baseline is 4. The description adds context about the tool's output scope (question, reporting, action coverage), which goes beyond the schema. It does not need to document parameters since there are none.

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 identifies the tool as showing 'Teamtailor Ops Control Plane' coverage and distinguishes it from sibling get_* tools for specific entities. The verb 'Show' is specific, and the resource is well-defined, though the phrase 'question, reporting, and action coverage' is somewhat jargon-heavy.

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 intended use is implied by the tool's name and description: it provides an overview of control plane capabilities. However, there is no explicit guidance on when to use this instead of alternatives like api_request or the entity-specific get_/list_ tools, nor any exclusions.

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