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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=false; the description adds nothing on top. It does not say what is created, whether duplicates are rejected, whether an organization/project key is needed, or what happens to the queue behaviour fields. No contradiction, but zero added value.

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 that are literally identical; there is nothing to front-load because no information is present. It is short but only by virtue of being empty, which is under-specification rather than concision.

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?

A non-idempotent mutation tool with a nested multi-field body, an enum-typed 'type' and 'queueBehaviour', and no output schema. The description covers none of the information needed to construct a valid request or understand the effect of creation.

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?

The single top-level parameter is a nested 'request' object with a required 'body' containing nine fields (type enum, position, queueBehaviour, possibleValues, filterInQueueIds, etc.), and the schema coverage metric is 0% for the top-level shape. The description does not explain the request/body wrapper, the required fields, or the semantics of any nested field, leaving the agent to reverse-engineer a deep object.

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 is a verbatim restatement of the tool name and annotation title ('Create an action'), which is tautological. It provides no resource detail (what an 'action' is in this moderation/queue system) and does nothing to separate it from siblings such as actions-update, actions-delete, or actions-execute.

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 tool, no prerequisites, and no mention of alternatives. With six other actions-* siblings present, the agent gets no routing signal at all.

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