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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds a small amount of useful scoping by saying 'one report' and 'basics about the issues,' but it does not disclose additional behavioral details such as how much of the issue details are returned or any limitations.

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 one sentence with no wasted words and the core subject is front-loaded. It is concise and readable, though slightly vague in what 'details' means.

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 simple two-parameter read-only tool with an output schema and safety annotations, the description provides enough subject scope to be minimally viable. However, it still leaves ambiguity about how listIssues differs from getReport and listDiagnoses, which is a meaningful gap.

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 description coverage is 100%, and both parameters already have meaningful descriptions and examples. The description does not add parameter-level nuance, but because the schema carries the full burden, a baseline of 3 is appropriate.

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 names a resource ('one report') and a topic ('issues reported in it'), but the verb 'Provide details' is generic and doesn't clearly state that this tool lists issues. It also overlaps with sibling getReport, which likely also provides report details, so an agent cannot confidently differentiate them from the description alone.

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?

No explicit guidance is given about when to use this tool versus alternatives such as getReport or listDiagnoses. The only implied context is that the caller must identify a report via jobID and timeStamp, but there are no exclusions or conditions for choosing a sibling.

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