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

Annotations already cover idempotency and non-destructiveness; the description adds the meaningful nuance that this both creates and reuses an existing link, which is exactly the behavior a retry depends on. The security note (share only with the intended client) and the uncertain-result recovery path add real context. It stops short of describing token lifetime or what the returned link contains.

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?

Three short sentences with zero filler; the purpose and the security caution come first, and the sibling routing comes last. Every clause earns its place.

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 single-parameter, idempotent, non-destructive tool with a fully documented schema, the description covers purpose, safety, and failure recovery. The one gap is that there is no output schema, so a word about the returned link (URL form, expiry/reusability) would have completed the picture.

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?

Only one parameter and schema description coverage is 100%, with the schema itself warning 'never a personal platformId'. The description adds no further meaning about workspaceId, so the baseline 3 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 (generate or reuse) and a specific resource (a private Workspace link for connecting client channels). The closing sentence explicitly routes the agent away from company_get_connection_link and company_rotate_connection_link, so it is distinguishable from the three tightly-related siblings.

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?

Gives a concrete safety rule ('Share only with the intended client') and an explicit error-path instruction ('After an uncertain result use company_get_connection_link, not rotation'). It lacks a general statement of when to prefer generate/reuse over an explicit rotate, but the routing it does provide is actionable.

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