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

The description adds useful behavioral context beyond the sparse annotations (only destructiveHint=false) by explaining the sub-path concatenation with an example and mentioning dryRun preview. However, it does not address permissions, side effects of actual creation, or response behavior, and much of the behavior is also present in the schema descriptions.

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?

Two sentences with no filler. The first states the action; the second provides a concrete example and the dryRun tip. Every sentence earns its place, and the most important behavioral information is front-loaded.

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?

The description and schema together cover required parameters, path construction, and preview mode. For a create operation without an output schema, the missing return-value or permission details are minor, and the provided information is sufficient for an agent to invoke the tool correctly.

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 coverage is 100%, so the baseline is 3. The description adds value by giving a concrete example of how 'name' and 'location' interact: location 's3a://mybucket' + name 'mydatabase' → 's3a://mybucket/mydatabase'. This clarifies relationship semantics beyond the individual property descriptions.

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 states a specific verb and resource: 'Create a database in a Data Catalog catalog.' It clearly distinguishes this tool from sibling operations like get_database, update_database, and create_scanner. The sub-path behavior adds concrete scope.

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 provides clear context for when to use this tool (creating a database) and adds a practical usage tip: 'Use dryRun=true to preview without creating.' It does not explicitly name alternative tools, but the create-versus-read/update distinction is obvious enough.

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