get_member_profile

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

With no annotations provided, the description carries the burden of explaining behavior. It discloses that the tool returns the page's text content (bio, tags, links, etc.), which is useful behavioral information. It does not explicitly state that the operation is read-only or discuss error handling, but 'Fetch' implies a non-destructive read.

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 two sentences long, front-loads the core purpose, and includes a useful example without excess. Every sentence contributes value, and the structure is clean.

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?

Given the tool has a single required parameter and an output schema, the description sufficiently covers the input format, the source of valid inputs, and the nature of the returned content. It is complete for a simple fetch operation, with no significant gaps.

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 input schema only specifies the parameter name and type, so the description adds critical meaning by explaining that 'profile' can be a profile URL or a UUID from search results, with a concrete example. This fully compensates for the 0% schema description coverage.

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 uses a specific verb ('Fetch') and resource ('member's full profile page'), and distinguishes itself by explaining the input can be a profile URL or UUID from search results. This clearly separates it from sibling tools like search_members, which find members rather than fetch a full 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?

It provides clear context for when to use the tool—after obtaining a profile URL or UUID from search results—and includes an example. However, it does not explicitly mention when not to use it or name alternative tools, so it stops short of fully explicit guidance.

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