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

With no annotations provided, the description carries the full burden. It discloses important behavior: returns the CSV as text and may be truncated for large reports. It does not cover authentication, error handling, or data format details, but the truncation warning is valuable transparency beyond the schema.

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 concise, front-loaded with the main action, and each sentence earns its place. It clearly separates purpose, return behavior, and parameter explanation in a structured way without unnecessary fluff.

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 single-parameter tool with no output schema, the description covers the essential aspects: what it does, what it returns, and its limitation (truncation). It could mention additional details like file size limits or authentication prerequisites, but given the compact scope, it is sufficiently complete.

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%, so the description must compensate. The 'Args' section states 'download_url: Download URL from youtube_reporting_list_reports', which adds provenance and usage context beyond the schema's bare name and type. This effectively clarifies how to obtain the value.

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 'Download a report CSV' with a specific verb and resource. It distinguishes itself from sibling reporting tools like list_reports and create_job by explicitly focusing on downloading the report content. The action and target are unambiguous.

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 its usage by saying the download URL comes from youtube_reporting_list_reports, which provides context on when to use this tool. However, it does not explicitly state when not to use it or mention alternatives, so it stops short of full guidance.

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