channels_findCreators

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It describes the filtering capabilities but does not state that the operation is read-only, what the output format is (e.g., list of channel objects), whether it has rate limits, or any side effects. This is a significant gap for a tool with 12 parameters.

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 a single concise sentence that covers the core purpose. It is front-loaded and efficient, but could be slightly more structured to separate the main action from filter details. No unnecessary words.

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 has 12 parameters, no output schema, and no annotations, the description is insufficiently complete. It does not explain the return type, pagination behavior, or how 'from video mentions' works algorithmically. The minimal description leaves many questions for the agent.

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 100%, so the input schema already documents all 12 parameters. The description provides a high-level summary ('subscriber band and recent activity filters') but does not add additional meaning beyond what the schema offers. Baseline score of 3 is appropriate.

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 tool finds creator channels from video mentions, with filters for subscriber count and activity. It uses a specific verb 'find' and resource 'creator channels', and the phrase 'from video mentions' distinguishes it from sibling tool channels_searchChannels which likely searches by name or other criteria.

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 implies usage through its specialized functionality, mentioning 'in one call' which suggests efficiency. However, it does not explicitly state when to use this tool versus alternatives like channels_searchChannels, nor does it give guidance on when not to use it. The context is clear but lacks explicit directions.

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