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

Annotations already establish readOnlyHint=true, so the agent knows this is a safe read operation. The description adds meaningful behavioral scope by stating the response covers availability and how to book, without claiming any booking side effect. No contradiction exists.

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?

One tightly packed sentence front-loads the action and object ('List the professional services on offer') and follows with useful qualifiers. Every word earns its place; no filler or repetition of schema fields.

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 parameterless, read-only list tool with an existing output schema, the description covers all necessary context: what is listed, the domain of the services, and the availability/booking details. Nothing needed for correct invocation is missing.

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 has zero parameters, so the baseline for this dimension is 4. The description still helps by explaining what the returned list contains (offerings, availability, booking instructions), which is the only semantic content an agent could need.

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?

States a specific verb ('List') and resource ('professional services'), and goes beyond a label by naming the exact offerings (AI architecture advisory and mentoring) plus the availability/booking details. This distinguishes it clearly from sibling tools that cover profile, certifications, experience, projects, publications, and articles.

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 makes the tool's scope obvious—services, not profile credentials or publications—so an agent can select it without overlap. It does not explicitly name alternatives or exclusion conditions, but the sibling set is distinct enough that no stronger routing guidance is needed.

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