Read-only

Compare the same timestamp across 2-5 videos to see what different creators show or say. Returns transcripts and visual frames side by side for analysis of tutorials, reactions, or event coverage.

Instructions

MULTI-VIDEO TOOL: Compare the same timestamp across 2-5 videos. See what different creators show/say at the same moment. Returns transcript + visual frames side by side. Great for comparing tutorials, reactions, or coverage of same event.

Behavior4/5

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

Discloses that it returns 'transcript + visual frames side by side', adding detail beyond annotations that declare readOnlyHint=true. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences, each essential. Front-loaded with 'MULTI-VIDEO TOOL' label, and no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Describes what the tool does and output type, but lacks details on limits (e.g., video duration) or frame resolution. Adequate for the complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers both parameters with descriptions; tool description reiterates '2-5 videos' but adds no new meaning beyond schema. Baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'Compare the same timestamp across 2-5 videos' with specific verb and resource, and distinguishes from sibling tools like 'get_video_moment' which handles single videos.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides context with 'Great for comparing tutorials, reactions, or coverage of same event' but does not explicitly state when not to use or mention alternatives.

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