List videos in a VOD channel

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description's '[READ]' tag duplicates readOnlyHint, while the endpoint path adds modest context that this queries the offline FA API. It says nothing about pagination or result size.

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?

Extremely short and front-loaded with the '[READ]' marker followed by the endpoint. Nothing is padded, though the brevity borders on under-specification rather than efficiency.

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?

For a simple read-only list tool with full annotation coverage and 100% schema coverage, the description is minimal but serviceable. It does not describe the return shape or pagination, though no output schema exists to carry that load.

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?

With 1 parameter at 100% schema description coverage, the schema already documents channel_id and its provenance ('Exact channel id from list_vod_channels'). The description adds no parameter detail, so the baseline 3 applies.

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 name/title state a specific verb+resource (list videos in a VOD channel), but the description body merely restates this as a REST endpoint mapping. It gives no differentiation from close siblings like get_vod_video or list_vod_channels.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as get_vod_video for a single video or list_vod_channels for the parent list. The agent must infer usage from the endpoint path alone.

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