Deactivate WordPress plugin

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

The description usefully discloses that the operation is asynchronous and that a successful response only means the job was queued. This adds meaningful behavioral context beyond the annotations, which only indicate readOnlyHint=false and destructiveHint=false.

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 concise and front-loaded. The core purpose appears in the first sentence, followed by essential parameter-retrieval guidance and the async caveat. Every sentence earns its place with no wasted wording.

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 tool with three required parameters, no output schema, and clear annotations, the description covers the essential points: what it does, the async job semantics, and where to get the software identifier. Minor gaps remain around the meaning of `username` and how to verify job completion, but these do not severely impair correct invocation.

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 baseline is 3. The description adds real value by explaining exactly where to retrieve the `software` identifier from an existing API response. It also clarifies `plugin` as a slug. The `username` parameter remains under-explained, but the schema description covers it minimally.

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 clear verb and resource: 'Deactivate an installed plugin on a WordPress installation.' This distinguishes it effectively from sibling tools like hosting_activateWordPressPluginV1, hosting_installWordPressPluginsV1, and hosting_uninstallWordPressPluginsV1.

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 gives operational guidance, such as how to obtain the WordPress installation identifier from the list endpoint. However, it does not explicitly explain when to choose deactivation over activation, installation, or uninstallation, leaving tool selection largely to inference from the tool name and siblings.

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