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

With no annotations, the description carries the full burden. It does disclose the auth requirement (platform staff, account session) and enumerates the status values an entry can carry, including the withdrawn/revoked distinction, which is genuine behavioral context. It says nothing about result volume, pagination behavior, or ordering, so the disclosure is partial.

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 compact sentence that front-loads the access restriction before the payload description. The parenthetical status enumeration is dense but informative; nothing is wasted, though the phrasing is clipped to the point of being elliptical.

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 two-parameter list tool with no annotations and no output schema, the description covers who can call it and roughly what comes back, but leaves pagination and result-size behavior entirely unexplained. It is adequate but has a clear hole.

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 coverage is 0% and neither limit nor offset has a schema description, so the description is the only place pagination semantics could be explained — and it never mentions them. The mention of 'expiry' describes a returned field, not either parameter, so it does not compensate for the 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 the resource (support access requests and grants) and the data returned (status values, expiry), which is enough to distinguish it from mutation siblings like platform_access_request and platform_access_end. The verb is only implied via the name's 'list', but the noun phrase is specific enough that an agent can identify the operation.

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?

It states a hard audience constraint — 'Platform staff only (account session)' — which tells the agent who may call it, but gives no guidance on when to choose it over related siblings such as support_list or platform_access_request. Usage is implied rather than stated.

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