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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds two pieces of genuine value: the required OAuth-style scope and the fact that events carry no content payload. It omits pagination behavior (default limit 50, before_id cursor), which would matter for a paged endpoint.

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?

Two compact sentences with no filler, and the resource scope is front-loaded before the auth requirement. It is efficient, though the terseness contributes to the missing parameter and pagination detail.

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?

This is a simple, low-parameter, no-output-schema tool, so expectations are modest, but the description still leaves out what an agent needs to call it well: what an 'audit event' contains, how to page through results, and how limit/before_id behave. The 'content-free' note is helpful but insufficient.

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 0% across two parameters (limit, before_id), and the description says nothing about either. Neither the default page size, the 500 maximum, nor the meaning of before_id as a cursor is explained anywhere, so the description fails to compensate for the schema gap.

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 specific resource (audit events) and scope (for the account), with the verb implied by the tool name. 'Content-free' usefully qualifies what kind of events these are. It does not, however, distinguish this from siblings like get_usage, which plausibly overlaps in intent.

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 only guidance is an auth prerequisite ('Requires scope usage:read'), which is a constraint rather than a when-to-use rule. There is no statement of when to prefer this over get_usage or what it excludes, leaving selection to inference.

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