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

With no annotations provided, the description carries the disclosure burden. It clearly communicates that this is a read-only profile retrieval and lists the specific information returned, implying no side effects or destructive behavior. It does not detail authentication or data freshness, but the absence of parameters and the informational nature keep the gap small.

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 focused sentences with no filler. The main identity of the tool is front-loaded, the content list is compact, and the usage guidance is delivered in a single clear directive.

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 simple, zero-parameter profile-fetch tool, the description is complete: it names the subject, lists the returned fields, and tells the agent when to use it. No output schema or nested structures exist, and the description sufficiently covers what an agent needs to select and invoke it correctly.

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 (0 parameters), so the baseline is 4. The description adds meaningful contextual information about what the profile contains, even though there are no parameters to document. It does not need to compensate for schema gaps because 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 begins with 'Full professional profile of Laurent Knauss' and enumerates the contained data (title, location, availability, contact, socials, certifications, booking link), making the tool's function unambiguous. It clearly distinguishes from sibling tools like book_call, get_skill, and list_articles, which target different resources.

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 instruction 'Use this first to understand who he is and how to reach him' provides explicit context for when to call this tool and positions it as an initial step. It does not explicitly mention alternatives or exclusions, but for a zero-parameter profile lookup the guidance is sufficient.

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