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

Annotations declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the agent already knows this is a safe read operation. The description adds modest context ('audited' and the privacy filter) but does not describe return format or pagination. No annotation contradiction exists — 'List' aligns with the readOnly hint.

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?

A single, front-loaded sentence states the core purpose and adds the distinguishing qualifier in the same breath. The phrasing 'can be explained or run without collecting personal information' is slightly dense but compact with no wasted words.

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 zero-parameter list tool with annotations covering the safety profile and an output schema present, the description is complete. An agent has everything needed to invoke this tool correctly.

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 parameters, so the description carries no parameter burden; the baseline of 4 applies with nothing left to explain.

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 verb ('List') and resource ('audited revenue leak diagnostics'), and the qualifier about not collecting personal information helps set it apart from run_revenue_leak_diagnostic. It does not explicitly name or contrast siblings, leaving the get/run/list distinction to be inferred rather than stated.

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 alternatives or exclusions are named. The qualifier implies this tool is the non-privacy-invasive listing option among sibling tools like run_revenue_leak_diagnostic, but the when-to-use versus alternatives context is implied rather than made explicit.

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