RemixIcon MCP

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

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: the search returns 'top 5 most relevant icons', supports 'comma-separated keywords', and provides output format details. It doesn't mention rate limits, authentication needs, or error handling, but covers core functionality clearly.

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 efficiently structured with four sentences that each add value: purpose statement, input instructions, usage tip, and output format with example. It's front-loaded with essential information and avoids redundancy, making it highly concise.

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 single-parameter search tool with no annotations and no output schema, the description provides good completeness by explaining the search mechanism, result limits, input format, and output format. It could improve by mentioning pagination or error cases, but covers the core context adequately.

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 description coverage is 100%, so the baseline is 3. The description adds minimal value beyond the schema by reiterating 'comma-separated keywords' and mentioning the 'up to 20 keywords' limit, but doesn't provide additional semantic context or usage nuances not already in the schema.

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 specific action ('Search Remix Icon metadata') and resource ('icons'), with precise scope ('by keyword', 'up to 20 keywords', 'top 5 most relevant'). It distinguishes itself from potential alternatives by specifying the exact search mechanism and result limits, making the purpose unambiguous.

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 implied usage guidance through examples ('Avoid natural language sentences') and format specifications, but lacks explicit when-to-use scenarios or comparisons with alternative tools. Since no sibling tools are listed, this is adequate but not comprehensive.

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