flow_screenshot

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

No annotations are provided, so the description carries the full burden of disclosing behavioral details. It only states the action without mentioning where the screenshot is saved, whether it returns a file path, authentication requirements, or any side effects, leaving significant ambiguity for an agent.

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 sentence with no filler, immediately conveying the tool's action. It is appropriately concise and front-loaded, making it easy for an agent to parse.

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's simplicity (one optional param, no output schema, no annotations), the description is minimally adequate but incomplete. It fails to explain what happens after the screenshot is taken (e.g., file location, return value), leaving the agent without enough context to predict the tool's full behavior.

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 single optional parameter 'name' is fully described in the input schema (100% coverage), so the baseline is 3. The description adds no additional semantic detail about the parameter, but the schema already provides sufficient information.

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 a specific action ('Take a screenshot') on a specific resource ('the current Google Flow page'), making its purpose unambiguous. This distinguishes it from sibling tools like flow_download_latest or flow_create_scene, which serve different actions.

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 does not provide explicit guidance on when to use this tool versus alternatives. However, the intended use is implied by the action itself — taking a screenshot when a visual capture is needed — but no exclusions or alternative comparisons are mentioned.

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