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

The annotations already state readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the profiles relate to audit checks, but it does not disclose return format, ordering, completeness, or whether the explanation is static or dynamic.

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 short sentence with no filler, making it appropriately sized. The wording is slightly ambiguous because 'Explain' rather than 'List' may mislead about whether the result is a list or prose, but the structure is front-loaded and efficient.

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?

The tool is a zero-parameter, read-only listing operation with low complexity, and the description conveys the domain object being listed. It does not fully describe what each profile entry contains or whether all profiles are returned, but for a simple listing tool with no output schema the core context is present.

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 tool has zero input parameters, so there are no parameter semantics to document beyond the schema. The baseline score for zero-parameter tools is 4, and the description does not need to compensate for any schema gaps.

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 the specific resource—site-type profiles that add checks to an audit—and indicates it explains or lists them. However, the verb 'Explain' is not fully aligned with the tool name 'list_profiles', and it does not distinguish this tool from siblings such as run_audit or get_report.

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?

There is no explicit guidance on when to use this tool versus alternatives like run_audit or get_report, nor are there prerequisites or exclusions. Usage can only be inferred from the phrase about profiles that add checks to an audit.

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