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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the result is a short overview focused on strengths, but it does not provide meaningful extra behavioral context such as limits or handling of empty resumes.

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 short and front-loaded, with the purpose first and usage guidance second. The return-value sentence slightly overlaps the opening 'short overview' phrasing and is somewhat redundant because an output schema exists.

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's low complexity, full parameter schema coverage, annotations, and an output schema, the description provides everything needed to call it correctly. The agent knows the purpose, when to use it, and the general shape of the result.

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 single optional resumeId parameter is fully documented in the schema, including the behavior when omitted. The description adds no parameter-specific meaning beyond what the schema already provides, which is appropriate for 100% 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?

States a specific action on a specific resource: give a short overview of a saved resume. This is clear enough for an agent to know what the tool does, but it does not differentiate from nearby siblings such as check_resume or get_resume_statistics.

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?

Explicitly says to use it when the user wants to understand a resume's main strengths before making changes. That is a clear usage context, though it does not mention when not to use it or name an alternative tool.

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