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

Annotations indicate not read-only, but the description adds no behavioral context beyond 'Update'. No details on partial vs full replacement, side effects, or permission requirements.

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 concise single sentence with no unnecessary words. Efficiently conveys core action.

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?

Lacks essential details like return value, error handling, and behavior of the 'fields' object (merge vs replace). Incomplete for a tool with an arbitrary JSON object parameter.

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 description coverage is 0%. Description hints that 'fields' contains the fields to update, but does not specify valid fields or structure. Channel_id is not explained, though its purpose is inferable from name.

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 action (Update) and the resource (a VOD channel), distinguishing it from sibling tools like create, delete, get, and list.

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?

No guidance on when to use this tool vs alternatives, such as when to update vs recreate, or any prerequisites. Missing context on suitable scenarios.

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