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

The annotations already declare the operation is safe (readOnlyHint: true). The description adds crucial behavioral context by specifying the output is a 'concise' summary and formatted in Markdown, which goes beyond basic safety hints.

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?

It is a single, powerful sentence that defines the scope, content, and format of the output without unnecessary jargon or fluff.

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 tool with zero parameters, the description is complete by defining exactly what kind of information is included in the output (scope, content categories, and format).

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?

With zero parameters and 100% schema coverage, the baseline score applies. The description is sufficient for this parameter-less tool.

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 explicitly states its function: providing a concise overview of Novaeon, detailing what the studio builds and how it operates. This clearly defines the tool's purpose as a high-level summary tool compared to specific detail retrieval.

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?

While it doesn't explicitly contrast itself with sibling tools like get_page, the phrasing 'concise overview' implies it should be used when the user needs a summary rather than deep, specific content.

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