+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds authentication requirement and expected return fields beyond annotations (readOnlyHint, idempotentHint). No contradiction with annotations.
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?
Single sentence with clear structure, front-loads purpose. Uses semicolon effectively but could be more scannable.
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?
Covers return fields and basic behavior but fails to explain pagination parameters ('from', 'size') given schema coverage gap. Output schema partially mitigates return format documentation.
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 has no descriptions (0% coverage). Description explains 'query' as free-text or Lucene but omits 'from' and 'size' parameters, which are only hinted as numbers. Insufficient to guide proper parameter usage.
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?
Clearly states verb 'Search', resource 'Lens.org scholarly works', and specifies result fields (title, authors, journal, year, DOI). Differentiates from siblings like 'patent' and 'patents_search' by focusing on scholarly works.
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?
Mentions authentication requirement ('requires Bearer token') but offers no guidance on when to use this tool versus alternatives (e.g., 'scholarly' sibling). Does not specify constraints or best practices for query type selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
