flow_download_latest

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

No annotations provided, so description must clarify behavior. It states 'download' implying a read operation, but fails to disclose what happens if no file exists, whether it's a single download or can be called multiple times, or any side effects.

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?

Single sentence with clear verb-first structure. Every word is necessary, no wasted content.

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 parameterless tool, the description is mostly adequate but omits important context like the possibility of no file, expected return format, and relation to other flow tools. Additional context would improve completeness.

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 has zero parameters with 100% coverage, so baseline is 4. The description adds meaning by specifying 'most recently generated', which reduces ambiguity beyond the empty schema.

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 verb 'download' and the resource 'most recently generated file' from 'Google Flow'. It distinguishes from sibling tools like generation tools, but could be more specific about the scope of 'most recently generated'.

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 versus alternatives, nor prerequisites like ensuring a file has been generated. The description lacks context for proper selection.

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