Search videos

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

No annotations provided. Description discloses default previews and return format, but doesn't mention side effects or permissions (likely read-only). Adequate for a search tool but lacks depth.

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?

Two concise sentences: first states core function and output, second gives actionable next-step tip. No redundancy.

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 10 parameters and no output schema, description covers basic output and hints but doesn't explain search behavior or filter usage. Adequate but not comprehensive.

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?

Only 30% schema coverage. Description mentions previews default true but doesn't elaborate on other parameters like query, locale, orientation. Limited value 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?

Clear verb 'Search' and resource 'Pexels videos'. Description specifies return format (compact line with id, dimensions, etc.) and distinguishes from sibling 'video_storyboard'.

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?

Suggests using video_storyboard for deeper inspection, but no explicit guidance on when to use this vs alternatives like popular_videos or curated_photos. The search context is implied.

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