Activate Theme

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

With no annotations, the description carries the full burden of behavioral disclosure. It fails to mention that activating a theme will change the active theme, deactivate the previous one, or require the theme to be already installed. This lacks critical side-effect information.

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 a single, well-formed sentence with no wasted words. It is front-loaded and easily parsed, though its brevity borders on under-specification rather than effective concise communication.

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?

Given the lack of annotations and output schema, the description is insufficient. It does not explain the expected outcome, any prerequisites, or error conditions. A simple activation tool still requires context about its effects and dependencies, which is absent.

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 schema provides descriptions for all three parameters (theme slug, software identifier, username) with 100% coverage. The description does not add any additional meaning beyond the schema, so it remains at the baseline for high schema coverage.

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 'Activate a WordPress theme' uses a specific verb and resource, clearly indicating the tool's function. It distinguishes the action from sibling tools like wp_themes_install or wp_plugins_activate, though it does not explicitly differentiate from similar theme operations.

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?

No guidance is provided on when to use this tool versus alternatives, nor are prerequisites mentioned (e.g., the theme must be installed). The description gives no context for choosing this tool over wp_themes_install or wp_themes_update.

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