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

readOnlyHint=true already covers the safety profile, so the description only needs to add context. It adds that the profile is 'public' and scoped to one tutor, but does not mention auth needs, rate limits, or what happens on an unknown slug. Since no output schema exists, the return-content description ('full public profile') is thin.

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 tight sentence that front-loads the verb and resource and packs the slug provenance into a parenthetical. No wasted words.

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 lookup with no output schema, the description establishes scope and the upstream source of the identifier. It is largely sufficient, though it could say a little more about what the returned profile contains given there is no output schema to fall back on.

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 coverage is 0% and the single required 'slug' parameter has no inline description. The description partially compensates by telling the agent the slug originates from search_tutors, but it omits any format, casing, or length constraints (schema maxLength 80 is undocumented).

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') and resource ('full public profile for one TutorPing tutor'), with scope narrowed to a single record. It also hints at the sibling relationship by noting the slug comes from search_tutors, though it doesn't fully contrast against get_tutor_availability or other siblings.

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 phrase 'by slug from search_tutors' implies this is a follow-up lookup after a search, but there is no explicit when-to-use or when-not guidance, nor any stated alternative for retrieving tutor data.

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