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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds value beyond that by disclosing the shape of the payload (links to a PDF and a web copy) and warning that the substantive content lives inside those documents rather than in the response fields. No output schema exists, so this return-shape note is doing real work.

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?

Three short sentences, front-loaded with what the tool returns, followed by the no-input note and the sibling routing. Nothing is padded; the only mildly redundant phrase ('Takes no input') is a cheap and useful confirmation against the empty schema.

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 trivial, zero-parameter, read-only tool with no output schema, the description covers everything an agent needs: what it returns, that it needs no arguments, and when a sibling is a better fit. Nothing relevant 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?

There are zero parameters, which sets the baseline at 4. The description reinforces this with 'Takes no input', removing any doubt about whether filters or identifiers are expected.

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 and resource ('Links to Shlok's résumé') and enumerates exactly what comes back: a PDF download, a web version, plus title, summary, current role and education. It also explicitly distinguishes itself from the structured-data siblings, so an agent can choose without opening any schema.

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?

Gives a clear routing rule: use get_experience, get_skills and list_projects when the same facts are wanted as structured data, implying this tool is for the document itself. It stops short of an explicit 'use this when the user wants the résumé file/download' statement, but the alternative and its condition are named.

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