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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the useful disclosure of what fields are returned (domain, status, grade, id), but says nothing about ordering guarantees beyond 'most recent', the default count of 10, or that results are capped.

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?

One short, front-loaded sentence with no filler, which is appropriate for a simple list tool. It is efficient, though it spends its words on return fields while omitting the only parameter.

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?

With no output schema, naming the returned fields is genuinely helpful. However, for a tool whose sole parameter controls result count and whose default and maximum are invisible in the schema, the description leaves the agent unable to reason about result volume.

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 single limit parameter has 0% schema description coverage, so the description carries the full burden and it fails: limit, its default of 10, and its 1-100 range are never mentioned. 'Most recent' only loosely implies the recency ordering that limit interacts with.

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 (the account's audits) and its scope (most recent), and lists the fields returned, so an agent knows what it gets. The listing verb is only implied by the tool name/title rather than stated, but the resource is unambiguous.

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 guidance on when to use this versus get_audit or audit_site, despite get_audit being an obvious near-sibling for fetching a single audit. Nothing indicates that this is the browse/list entry point and get_audit is the fetch-by-id path.

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