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

readOnlyHint=true already establishes this is a safe read, and the description adds what is actually returned (schemas plus examples), which is meaningful context. It says nothing about result size, pagination, or what happens when an unknown action ID is passed, so it does not go far beyond the annotation.

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?

A single front-loaded sentence with no filler; the resource and the return payload are both stated immediately.

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?

There is no output schema, so the description must carry return-value meaning; 'schemas and examples' is a partial but honest summary. Missing are the 30-item limit's practical implication, ID format, and any hint that IDs come from a sibling listing tool.

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 0% and the only parameter is an untyped array of strings with a 30-item cap. The phrase 'one or more Studio actions' clarifies that actionIds are action identifiers and that multiple may be supplied, but the ID format and where to obtain valid IDs are not stated.

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?

States a specific verb ('Returns') and resource ('schemas and examples for one or more Studio actions'), so the operation is clear. It does not, however, explicitly distinguish itself from siblings like studio_list_capabilities or studio_list_examples, which appear to overlap in the same discovery space.

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 offers no when-to-use guidance, no prerequisites, and does not name an alternative tool. With three closely related discovery siblings (list_capabilities, list_examples, describe_capabilities), the absence of routing guidance leaves the agent to guess which one to call.

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