set_theme

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

No annotations provided; description states it switches theme but omits details on persistence, permissions, or side effects. Adequate for a simple action but minimal.

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 concise sentences, no unnecessary words. Front-loaded with action and resource, then provides guidance.

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 simple one-parameter tool with no output schema, description covers purpose and parameter sourcing. Could mention return behavior but not essential.

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 has no description for theme_id (0% coverage). Description adds crucial context: the id comes from list_themes, helping agent understand parameter source and format.

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?

Description clearly states action (switch theme), resource (application theme), and how to find theme ids using list_themes. Differentiates from sibling tools like update_theme and list_themes.

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?

Explicitly instructs to use list_themes to find ids, implying prerequisite step. Does not explicitly exclude other uses, but context is clear. Could improve by noting not for creating themes.

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