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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds the output format (JSON) and the breadth of the export, which is useful context beyond the annotations, but it says nothing about result size, whether the export is a snapshot or streamed, or any cost/latency implications of a full-account dump.

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 with no filler; the scope comes first and the enumerated contents follow. It is appropriately sized, though a short clause on output volume would have been worth the space.

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 no-parameter read-only export, knowing the resource scope, the included object categories, and the JSON format covers what an agent needs to select and call it. With no output schema, a brief note on the response structure would have made it fully complete.

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 has zero parameters and 100% description coverage, so there is nothing for the description to clarify parametrically. Baseline 4 applies.

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 (export) and resource scope (all of this account's objects) and enumerates the contents — keys metadata, requests, usage — so the agent knows this is a full-account dump rather than a single-resource fetch like the sibling get_usage or list_requests. It stops short of explicitly naming a sibling to contrast against.

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 phrase 'all of this account's objects' implies this is the tool to use when a complete snapshot is needed instead of the narrower getters, but it never says when to prefer it over approvalgate_get_usage or approvalgate_list_requests, nor any preconditions. Usage is inferable but not stated.

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