update_video_metadata

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

No annotations are provided, so the description carries full burden. It describes the update operation but does not disclose side effects, auth requirements, rate limits, or whether changes are irreversible. The partial update hint is helpful but not exhaustive.

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 sentences, no redundancy. The purpose is front-loaded, and the partial update instruction is concise.

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 6-parameter tool with no output schema, the description covers the essential update semantics. It implies that only provided fields are changed, which is critical. Could mention that omitted fields remain unchanged, but it's already clear from 'Only provide fields you want changed.'

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 low (17% – only category_id has a description). The description compensates by listing the fields and emphasizing partial updates, adding meaning beyond the schema's property names and types. However, it does not explain formatting for tags or category_id further.

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 it updates video metadata, listing specific fields (title, description, tags, category, privacy). This distinguishes it from sibling tools like delete_video or get_video.

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 explicitly says 'Only provide fields you want changed,' indicating a partial update pattern. It does not explicitly state when to use vs. alternatives, but the context is clear.

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