get_modern_trends

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool returns information, implying a read-only operation, but doesn't cover aspects like data freshness, source credibility, rate limits, or error handling. For a tool with zero annotation coverage, this is a significant gap in transparency.

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 a single, efficient sentence: 'Returns current visual design trends and what trends to avoid.' It's front-loaded with the core purpose and avoids unnecessary words. However, it could be slightly more structured by explicitly mentioning the lack of parameters or output format.

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 complexity is low (0 parameters, no annotations, no output schema), the description is minimally adequate. It states what the tool does but lacks details on behavior, usage context, or output format. With no output schema, the description doesn't explain return values, which is a gap, but the simplicity of the tool keeps it from being completely inadequate.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add parameter details, but since there are no parameters, this is acceptable. Baseline is 4 for 0 parameters, as the schema fully covers the lack of inputs.

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's purpose: 'Returns current visual design trends and what trends to avoid.' It specifies the verb 'returns' and the resource 'visual design trends' with additional context about 'what trends to avoid.' However, it doesn't explicitly differentiate from siblings like 'get_design_principles' or 'get_layout_patterns,' which might overlap in design guidance.

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 no guidance on when to use this tool versus alternatives. It doesn't mention any context, prerequisites, or exclusions, and with multiple sibling tools like 'get_design_principles' and 'get_layout_patterns' that could be related, the lack of differentiation leaves the agent without clear usage instructions.

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