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

No annotations given; description implies read-only browsing, but does not explicitly state no side effects, rate limits, or pagination behavior. Minimal but accurate.

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, front-loaded, no wasted words. Efficiently communicates core purpose and options.

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?

Simple tool with two optional params and no output schema. Description covers purpose and filter, but omits return format or pagination hints. Adequate but not rich.

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 coverage is 100%; description only rephrases 'filtered by category' which is in schema. No added meaning for 'limit' parameter beyond 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?

Clearly states verb 'browse', resource 'skills-hub.ai catalog', sorting 'by popularity', and optional filter 'by category'. Distinguishes from siblings: get_skill_detail (detail), install_skill (install), search_skills (search).

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?

Implies usage for browsing popular/filtered skills, but lacks explicit 'when to use' vs search_skills. No guidance on when not to use or alternatives beyond sibling names.

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