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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile needs no restating. The description adds the terminology mapping, which is genuinely useful, but says nothing about result volume, ordering, or whether the list is account-wide vs. filtered — relevant for a tool that returns a list.

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 sentence, front-loaded with the verb and resource, with the terminology clarification folded into a parenthetical instead of a separate clause. Nothing is wasted and nothing important is buried.

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 read with annotations covering safety and no output schema to explain, the description covers what an agent needs to select and call it. A brief note on how a request page differs from a request entry would close the remaining gap against the dense sibling list.

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 takes zero parameters, so the schema imposes no semantic burden and the baseline of 4 applies. The description correctly implies a single scope (the whole account) rather than suggesting any filtering that has no parameter to support it.

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?

A specific verb plus resource ('List the account's file requests'), and it resolves a real naming ambiguity by equating 'file requests' with 'request pages' as used elsewhere in the toolset. It stops short of distinguishing this from near-neighbors such as list_request_entries or get_request_progress, so an agent must infer the container-vs-contents relationship.

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?

Usage is only implied: the tool is the natural entry point for enumerating request pages, but nothing states when to prefer it over list_request_entries or get_request_progress, nor any preconditions. The parenthetical alias is the only indirect guidance, mapping user vocabulary to the toolset's term.

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