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

Annotations establish readOnlyHint=true; description adds valuable behavioral context by disclosing exactly which theme components are returned (colors, fonts, header/footer HTML), which helps the agent understand the scope and shape of the data without contradicting safety annotations.

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?

Single efficient sentence front-loaded with the action verb. Every clause earns its place: the main clause establishes the operation, while the prepositional phrase specifies the thematic domains returned. No redundancy or filler.

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?

While lacking an output schema, the description compensates by enumerating the primary return value categories (colors, fonts, HTML). Adequate for a simple read operation, though explicit mention of whether this returns the active/live theme versus pinned version would improve completeness.

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?

Zero parameters (input schema is empty object), which per guidelines warrants a baseline score of 4. The description appropriately implies no filtering or input is required to retrieve the current theme settings.

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?

Excellent specificity with verb 'Get', resource 'theme settings', and concrete examples of returned data (colors, fonts, custom HTML). The term 'current' implicitly distinguishes this from sibling version-management tools like get_theme_version and update_theme.

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?

Provides no explicit guidance on when to use this versus get_theme_version/get_theme_versions or whether this retrieves the active/pinned version. No prerequisites or exclusions mentioned.

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