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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=true, and openWorldHint=true. The description adds useful behavioral detail beyond those annotations: pausing is immediate, the last publication and draft are preserved, the no-op state is 'already_paused', and no durable pause receipt exists. It does not discuss authorization or confirmations, which keeps it from a 5.

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?

The description is two short sentences with no wasted text. The primary effect is front-loaded, and the edge-case behavior follows immediately.

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?

The tool is low-complexity, has one fully documented parameter, rich annotations, and an output schema. The description covers the core action and the important already-paused edge case. It is nearly complete, though it would be stronger if it explicitly routed agents to resume or publish siblings.

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?

There is only one parameter, agent_id, and schema description coverage is 100%. The schema itself explains that the value comes from agents_list or agent_create. The description adds no parameter-level guidance, which is acceptable given the high schema coverage but does not exceed the baseline.

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 states a specific verb and resource: it pauses Agent responses immediately. It also adds the preservation behavior for the last publication and draft. It does not explicitly differentiate itself from siblings such as publication_restore or publication_publish, so it falls short of a 5.

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 usage context is implied by the verb 'pauses' and by the note that the effect is 'already_paused' when the Agent was not live. However, it does not explicitly say when to choose this tool over publication_restore or publication_publish, nor does it state prerequisites such as permissions.

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