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

Annotations already flag readOnlyHint=false, destructiveHint=true and openWorldHint=true; the description adds that the result is a publicly accessible link viewable by anyone, which clarifies the exposure risk behind the destructive flag. It does not say whether sharing can be revoked, whether permissions are required, or whether repeat calls are idempotent.

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 front-loaded sentence with a colon clause that states the mechanism and its consequence. No filler, no repetition of the title.

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, no-output-schema tool the description is nearly sufficient: it says what is toggled and that the link is returned. What remains unaddressed is reversibility (can the link be turned off) and the permission requirements implied by destructiveHint=true.

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, deck_id, and schema description coverage is 0%, so the description carries some burden. However the parameter name is self-explanatory and the schema already documents the string type and length bounds; the description adds no format or sourcing detail (e.g., where to obtain the id).

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?

"Turn on the public link for a deck and return it" gives a specific verb (enable public sharing) and resource (deck), and the effect clause distinguishes it from read-only siblings like see_deck or list_decks. It stops short of explicitly naming a sibling or exclusion, so it lands just below the top band.

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 statement of when to use this versus alternatives such as see_deck or submit_deck, nor any prerequisite or exclusion. The public-link consequence implies a use case, but the agent is left to infer it.

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