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

Annotations already declare readOnlyHint=true, so the description does not need to emphasize safety. The description adds value by specifying that both metadata and content are returned, but it does not disclose potential edge cases (e.g., 404 if not found) or permissions needed. The behavioral disclosure is adequate but not extensive.

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 a single sentence of 10 words—succinct and directly informative. No extraneous information, perfectly sized for an agent to process quickly.

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 presence of an output schema, the description does not need to detail return values. It adequately covers what the tool does (get metadata and content) and requires only an ID. Minor omission: it could mention error handling or that it retrieves a previously saved cover letter, but overall it provides sufficient context for correct invocation.

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 100%, and the parameter description ('Cover letter UUID identifier') is clear. The tool description does not add additional semantic information beyond the schema, so it meets the baseline expectation of 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?

The description clearly states the tool retrieves metadata and content for a specific cover letter by ID. It uses a specific verb ('Get') and resource ('cover letter'), and the scope ('by its ID') distinguishes it from siblings like list.

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 implies use when you have a cover letter ID and want its details, but it does not explicitly state when to use this tool over alternatives like list, create, or generate. No 'when not' or alternative guidance is provided, which is a gap given the number of siblings.

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