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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds a content trait, that results are editorially curated and avoid unmeasured growth/income claims, which is mild but real behavioral context about the payload. It says nothing about result size, pagination, or freshness.

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 compact sentence with the core purpose front-loaded. The trailing clause about growth/income claims is a slightly odd disclaimer but does not bloat the definition.

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?

With no parameters and no output schema, the description is the only source of information, and it does not explain what a 'spotlight' actually contains or how results are shaped. Adequate for a parameterless discovery call, but thin for an agent trying to decide whether the output is useful.

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?

The tool takes zero parameters, so there is no parameter semantics to document; the schema is trivially complete. Baseline 4 applies since the description cannot and need not add parameter detail.

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?

It states a verb and a resource ('Get curated workflow spotlights'), and the term 'spotlights' is distinctive enough to separate it from the model-centric siblings. However, 'workflow spotlights' is never defined, so an agent cannot tell whether this returns workflows, marketing blurbs, or templates.

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?

No when-to-use guidance, no trigger conditions, and no mention of alternatives. Nothing tells the agent when this discovery tool is preferable to, say, list_models or get_prompt_tips.

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