zernio_get_youtube_playlists

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

No annotations are provided, so the description carries the burden. It implies a read operation but does not explicitly confirm it or disclose any side effects. The description could be improved by stating that the tool is read-only and that it returns a list of playlists.

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 of 17 words. It front-loads the core purpose and provides essential context without any extraneous information.

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 retrieval tool with one required parameter and no output schema, the description is sufficiently complete. It explains what the tool does and why it's needed. However, it could mention the expected output format or any limitations, but that is not strictly necessary given the tool's simplicity.

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 already describes 'accountId' as 'The Zernio YouTube account ID'. The description adds minimal value by emphasizing 'connected YouTube account', but this is a minor nuance. With 100% schema coverage, the baseline is 3.

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 (Get), resource (YouTube playlists), and context (connected YouTube account). It also explains the tool's need for uploading videos to specific playlists, distinguishing it from other sibling get tools.

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 implicitly provides usage context by mentioning 'connected YouTube account' and the purpose of uploading videos. It does not, however, explicitly state when to avoid using it or list alternative tools, but the context is clear enough for an agent.

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