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

Description aligns with readOnlyHint annotation (read operation implied by 'Get'), but adds no additional behavioral context such as what profile data contains, caching behavior, or default values when profile doesn't exist.

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?

Single sentence of appropriate length. Front-loaded with verb and zero extraneous 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?

Adequate for a simple single-parameter read operation, but lacks specification of what constitutes a 'profile' or return structure given no output schema exists.

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?

With 100% schema coverage and only one parameter (agent_id fully described as 'Agent identifier'), the schema carries the load. Description adds no parameter-specific guidance, warranting baseline score 3.

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 specific verb 'Get' and resource 'profile' for an agent. Clear basic purpose, though it could explicitly differentiate from sibling 'update_profile' beyond the implicit verb contrast.

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?

Provides no guidance on when to use this tool versus siblings like 'update_profile' or 'check_health', nor prerequisites for the agent_id parameter.

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