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

The description adds valuable context beyond the 'openWorldHint' annotation by emphasizing the importance of pre-calling 'getThemeSchema' to understand available fields and requirements. This discloses a behavioral trait (dependency on schema knowledge) that annotations do not cover, though it could mention potential outcomes like error handling or creation confirmation.

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 front-loaded with the core purpose in the first sentence, followed by a crucial usage guideline. Both sentences earn their place by providing essential information without redundancy, making it highly efficient and well-structured for quick comprehension.

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 the tool's complexity (creation with nested objects) and lack of output schema, the description is mostly complete by covering purpose and critical preconditions. However, it could enhance completeness by briefly mentioning what happens post-creation (e.g., returns a theme ID or confirmation), though the guidelines partially compensate for this gap.

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 100% schema description coverage, the schema already documents both parameters ('realm' and 'themeData') well. The description adds minimal semantics by implying 'themeData' must be prepared via 'getThemeSchema', but does not elaborate on parameter meanings or usage beyond what the schema provides, meeting the baseline for high coverage.

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 action ('Create a new theme') and the resource ('for a realm in PingOne AIC'), making the purpose specific and unambiguous. It distinguishes this tool from siblings like 'updateTheme' or 'setDefaultTheme' by focusing on creation rather than modification or configuration.

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 on when to use this tool: it instructs to call 'getThemeSchema first' to understand fields, types, enums, and requirements before creating a theme. This directly addresses when to use it (after schema retrieval) and implies an alternative (getThemeSchema) for preparation, ensuring proper usage.

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