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

With readOnlyHint=true already indicating a safe read, the description adds valuable behavioral context beyond annotations: it explains that stale keys resolve to the current Provider and that the returned key is always canonical. It does not cover error handling or rate limits, but the stale-key behavior is a meaningful disclosure.

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?

The description is front-loaded with the core purpose and then provides dense but relevant detail about the return payload. It avoids fluff, though the single long paragraph could be better structured with line breaks for readability; every sentence contributes information.

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?

Given no output schema, the description thoroughly describes the returned fields (display name, verified flag, member seats, roster size, country composition, software grouping, hostname counts) and explains the stale-key resolution. For a single-parameter read tool, this is complete enough for an agent to know what to expect.

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 100%, so the key parameter is already documented in the schema. The description adds semantics by clarifying that stale keys are accepted and resolve to the current Provider, and that the returned key is canonical, which goes beyond the schema's simple example-based description.

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 clearly states a specific verb and resource: 'Get an access point' and then defines it as 'One Provider's detail', listing the returned data. It does not differentiate this tool from close siblings like get_provider or get_public_provider, so it is clear but lacks sibling discrimination.

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?

There is no explicit guidance on when to use this tool versus alternatives such as get_provider or list_access_points. The only usage-like detail is the stale key resolution behavior, which is a special case rather than a general when-to-use statement.

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