flow_open_tools_gallery

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 behavioral disclosure. It only states what the tool does (opens a gallery and lists tools) but does not disclose any side effects, permissions required, or whether it returns data in the response. For a simple tool this might be acceptable, but the lack of explicit behavioral context is a gap.

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, compact sentence with no wasted words. It front-loads the action and resource clearly, making it immediately understandable.

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 (no parameters, no output schema, minimal annotations), the description covers the essential purpose. However, it leaves slight ambiguity about whether 'list available tools' means returning a list in the response or opening a UI gallery. This prevents a perfect score.

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 tool accepts zero parameters, so the schema coverage is trivially 100%. The baseline for 0 parameters is 4, and the description adds no confusion about parameters. Since there are no parameters to clarify, the description does not need to provide additional semantics.

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 opens the Google Flow Tools Gallery and lists available tools. This is a specific verb+resource combination that distinguishes it from sibling tools like flow_download_latest or flow_create_scene.

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 for discovering available tools, but does not explicitly state when to use this tool versus alternatives or mention any prerequisites. There are no exclusions or comparisons with siblings, so it relies on the name and context to convey intent.

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