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

The annotations already declare this is a non-destructive, idempotent, open-world write. The description adds real context on top of that: the collection becomes publicly visible, access is read-only, and external viewers can vote. It stops short of saying whether the link can be revoked and how an agent would do that, which is the main residual gap for a tool that changes public exposure.

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 sentences with no filler. The action and its effect come first, and the usage restriction is front-loaded in the second sentence where it is easy to apply before calling.

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 one-parameter tool with rich annotations and no output schema, this covers what the agent needs to decide to call it. The only missing piece is whether the response returns the public link itself, which would help the agent fulfill the user's goal of sending it to a client.

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 single collection parameter (name or id) is already fully documented in the schema. The description adds no further detail about accepted formats or resolution behavior, which is acceptable at this coverage level but is baseline rather than value-adding.

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 gives a specific verb and resource: it turns on the public, read-only link for a collection. It also states what recipients can do (browse and vote), which goes beyond the name and makes the effect unambiguous. No sibling tool overlaps with this action, so an agent can place it immediately.

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?

The second sentence is an explicit trigger condition: only call this when the user explicitly asks to share, and the parenthetical names the intended audience (a client). That is a clear when-to-use and when-not-to-use rule, not an implied one.

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