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

Annotations already indicate this is a safe, read-only, idempotent operation with a closed-world assumption. The description adds minimal behavioral context beyond this, such as specifying it retrieves 'detailed information' for a single issue, but does not elaborate on response format, error handling, or other traits like rate limits.

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 front-loaded with the core purpose in the first sentence, followed by a brief parameter explanation. It is appropriately sized with zero wasted words, making it efficient and easy to parse.

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 simplicity (one parameter), rich annotations covering safety and behavior, and the presence of an output schema, the description is reasonably complete. It could be improved by clarifying distinctions from sibling tools, but it adequately supports tool selection and 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?

The schema description coverage is 0%, but the description provides the parameter 'issue_key' with an example ('AXy1k...'), adding meaning beyond the bare schema. However, it does not fully compensate for the lack of schema descriptions, such as explaining key format constraints or validation rules.

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's purpose: 'Get detailed information for a single SonarQube issue by key.' It specifies the verb ('Get'), resource ('SonarQube issue'), and scope ('single'), but does not explicitly differentiate it from sibling tools like 'search_issues' or 'get_rule', which prevents a score of 5.

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 provides no guidance on when to use this tool versus alternatives. It does not mention sibling tools such as 'search_issues' for multiple issues or 'get_rule' for rule details, nor does it specify prerequisites or exclusions, leaving usage context unclear.

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