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

With no annotations provided, the description carries the behavioral disclosure burden. It clearly reveals that the tool is LLM-backed, grounded in khalidibnehasan.com content, and speaks as Khalid's persona rather than the real person, which is important context for setting expectations.

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 compact and front-loads the core action in the first sentence. The second and third sentences add crucial guidance about the persona's nature and the alternative ways to reach the real person without unnecessary verbosity.

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 one-parameter tool with no output schema, the description covers the tool's purpose, its behavior, its grounding, and the appropriate alternatives. Nothing essential is missing for an agent to use 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 schema already covers the single 'question' parameter at 100%, so the baseline is 3. The description reinforces that a question is asked but does not add meaningful new details about format, constraints, or expected input beyond what the schema provides.

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 states a specific verb ('asks'), a specific resource (Khalid's chat persona), and a clear outcome ('returns its answer'). It clearly distinguishes this from the sibling tools by framing it as the persona/chat tool rather than a data-retrieval tool.

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 explains when to use the tool (to ask about Khalid's work, experience, and availability) and when not to use it (to actually reach Khalid, use the contact form or book a call). This gives an agent actionable routing guidance.

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