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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds two useful facts beyond that: only 'published' profiles are returned, and the payload is schema.org Person JSON-LD. It does not say what happens for an unknown or unpublished slug (empty result vs. error).

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?

A single sentence that front-loads the singular scope and the return shape, with no filler. Every clause carries information an agent can use.

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 one-parameter read tool with complete annotations and a rich schema, the description covers resource, scope, and output format. The remaining gap is not-found/unpublished behavior, which matters for a slug lookup but is a minor omission overall.

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?

Schema description coverage is 100% and the slug parameter's schema entry already explains the format with a concrete example derived from get_team_directory. The description only restates 'by slug', so baseline 3 is appropriate.

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 (get), a single resource (one team member profile), and the return format (schema.org Person JSON-LD), scoped to slug and to published profiles. 'One' implicitly contrasts with the sibling get_team_directory, but no sibling is named, so it falls short of a 5.

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 gives no guidance on when to use this instead of get_team_directory or other siblings, and no prerequisites or exclusion conditions. The only routing clue (that the slug comes from a URL fragment found in get_team_directory) lives in the schema, not in the description.

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