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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description still adds real value beyond them: it scopes the result to 'this account', clarifies that access state is volatile (revoked/expired/temporarily unavailable), and states the response is metadata only — a meaningful disclosure about what is not returned.

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 short sentences, front-loaded with the core action, with no filler. The only inefficiency is the unexplained 'Private draft:' tag, which occupies prime position without telling an agent anything actionable.

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 zero parameters and an output schema present, the description only needs to convey scope and result nature — which it does via 'this account', 'current access state', and 'metadata only'. The one gap is the unexplained 'Private draft' qualifier, which may signal a stability or visibility caveat the description does not resolve.

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, which is the baseline-4 case. Nothing in the description misrepresents the input surface, and the account scoping is stated in prose even though it is implicit in the empty schema.

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?

Clear specific verb and resource: 'list this account's provider access requests and current access state.' An agent can distinguish it from request/cancel/disconnect siblings by the listing verb, though the description never names those siblings explicitly. The 'Private draft' prefix adds ambiguity rather than precision.

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 — an agent can infer this is the read/status counterpart to request_provider_access, cancel_provider_access_request, and disconnect_provider_access, but no when-to-use or when-not-to-use condition is stated. The note that approved requests can be revoked, expire, or become unavailable hints at the polling/status use case without committing to it.

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