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

Discloses the default apply behavior and the override option, but does not mention side effects on the existing layout, whether the operation is destructive, or any required permissions. No annotations are present, so the description carries full burden but leaves gaps.

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?

Extremely concise: two-line summary followed by bullet points for args. No redundant information. Front-loaded with the main purpose. Every sentence adds value.

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?

The description covers all three input parameters with clear examples. However, it does not explain the output of the generation (though an output schema exists), nor mentions error conditions or prerequisites. Given the tool's simplicity, it is largely complete.

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?

Since schema description coverage is 0%, the description provides essential meaning for all three parameters: free text examples for description, hex color and overriding behavior for accent, and default true for apply_to_buffer. This fully compensates for the lack of schema descriptions.

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 clearly states the tool generates a layout theme from a vibe description or brand color and applies it to the working buffer by default. This distinguishes it from sibling tools like 'list_theme_vibes' which only 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?

Provides clear context: use description for vibe text, accent for brand color, and apply_to_buffer to control application. However, lacks explicit guidance on when not to use or mention of alternatives like 'list_theme_vibes' for previewing existing themes.

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