List Gamma Themes

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds value by detailing the return structure (items with id, name, description, total, hasMore, nextOffset) and the optional response_format parameter, providing full transparency beyond 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?

The description is well-structured with sections for explanation, parameters, returns, and example. It is front-loaded with the main purpose and avoids unnecessary repetition. However, it could be slightly more concise (e.g., combining parameter descriptions).

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 no output schema, the description thoroughly explains the return values (items, total, hasMore, nextOffset) and ties the tool into the broader workflow with gamma_generate. All parameters are documented, and the example aids understanding. No gaps.

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% (all parameters have descriptions), so baseline is 3. The description adds an example that shows how parameters work together (e.g., { limit: 10, response_format: 'markdown' }), which provides concrete usage context that the schema alone does not.

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 lists available visual themes for Gamma content, and explains how themes control visual styling. It distinguishes itself from siblings by specifically mentioning it returns theme IDs used with gamma_generate.

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 provides explicit guidance to use returned theme IDs with gamma_generate's themeId parameter, implying this tool should be used before generating content. It lacks explicit when-not-to-use or alternative tool comparisons, but the context is clear.

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