Get My Unsplash Profile

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

Annotations already declare readOnlyHint=true and openWorldHint=true, but the description adds meaningful behavioral context beyond them: it exposes that private fields are included, that OAuth sign-in is required, and the exact login command. It also reinforces read-only behavior without contradicting any annotations.

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 three short sentences with no fluff. The core action and unique scope are front-loaded, and the prerequisite and read-only note are placed after the main purpose. Every sentence adds needed information.

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 no-parameter, self-profile retrieval tool, the description is adequately complete. It explains what is returned (private fields like email and remaining uploads), what is required (OAuth login), and the safety profile (read-only). With annotations and an empty schema, nothing essential for correct invocation 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?

The tool has 0 parameters and an empty schema, so there are no parameter details needed. The baseline for 0 parameters is 4, and the description does not need to compensate for any parameter coverage gaps.

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 ('Get'), a precise resource ('the authenticated user's own Unsplash profile'), and important scope details ('including private fields (email, remaining uploads)'). The word 'own' clearly distinguishes it from the sibling unsplash_get_user, which retrieves another user's profile.

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 makes the usage context clear: it is for the authenticated user's own profile, and it gives a concrete prerequisite ('run npx @hanoak/unsplash-mcp-server login first'). However, it does not explicitly state when not to use it or name alternatives, although 'own' and the sibling list make that inference easy.

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