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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds useful context on the access model (public vs verified vs specific-email links), but does not state reversibility or that existing access settings are reused rather than changed.

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 tight sentences with the core action front-loaded and no filler. The access-model clause is a legitimate second sentence rather than padding.

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-param mutation with no output schema, the description covers the action and link semantics, which is adequate. It leaves gaps on the target id, post-publish state, and how to undo, but annotations carry the risk profile.

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 compensate for the single 'id' parameter, yet it only says 'a brief' and never clarifies that the id identifies the document to publish. The schema's uuid format/pattern is the only real guidance.

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 (publish) and resource (a brief) plus the scope ('at its stable unlisted link using its current access settings'). This clearly separates it from unpublish_document, though it does not name that sibling explicitly.

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 description never says when to publish versus not, nor points to the inverse operation (unpublish_document) or prerequisites. The second sentence describes access behavior, not when-to-use guidance, so an agent gets little routing help.

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