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

Annotations declare readOnlyHint=false, destructiveHint=false, and idempotentHint=false, yet the description's 'Show' framing sounds purely read-only, and it explains nothing that reconciles the two — no statement of whether the call creates or regenerates a token, what permissions are needed, or what happens on repeat calls. With annotations present the bar is lower, but the description adds no behavioral context and arguably muddies the safety profile.

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?

A single short sentence with no filler, so it is efficient. Its brevity, however, leaves the front-loaded content too thin to orient the agent.

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 tool with an unexplained two-value enum, zero schema coverage, no output schema, and annotations implying a non-read-only effect, the description omits everything an agent needs to call it correctly. It never says what is returned or how the purpose value changes the result.

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 description coverage is 0%, so the description must carry the parameter burden, and it does not. The 'purpose' enum (status_view vs data_intake) is entirely undocumented and its effect on the returned link is unexplained; only business_id is weakly implied by 'a business's live share link'.

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 verb 'Show' plus 'share link' gives a rough idea, but 'Show a Copy button' describes a UI affordance rather than the tool's effect, leaving it ambiguous whether it creates, retrieves, or merely renders an existing link. Siblings create_share_link, list_share_links, and revoke_share_link make the distinction important, and the description never draws it.

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 guidance on when to call this instead of list_share_links (to enumerate links) or create_share_link (to generate one). No preconditions, no mention of whether a link must already exist, and no exclusions are stated.

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