Library Codec Distribution

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

No annotations are provided, so the description must convey behavioral traits. The one-line description only says it 'summarizes', but does not specify output format, whether it returns aggregated data, pagination behavior, or any side effects. This is insufficient for an agent to understand the tool's behavior.

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 extremely concise (4 words), which is economical but borders on under-specification. It could be slightly expanded to add crucial context without becoming verbose.

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?

Given the tool's complexity (11 parameters, no output schema, no annotations), the description is vastly incomplete. It does not explain the return value structure, what 'distribution' entails, or how the many parameters influence the result. The agent lacks essential information to use the tool effectively.

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?

The schema has 11 parameters with zero description coverage, and the tool description adds no meaning to any parameter. The agent receives no hints about what parameters like 'to', 'app', 'from', 'detail', 'fields', etc., control or how to use them.

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 verb (summarize) and resource (video codec distribution), making the core purpose understandable. However, it does not distinguish from the sibling 'codec_distribution' tool, which likely has a similar purpose but without the 'library' scope.

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 no guidance on when to use this tool versus alternatives like 'codec_distribution', 'audio_distribution', or other library-specific summaries. No context about prerequisites or typical use cases is given.

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