vibekit_database_schema

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It simply says 'Get' without stating whether the operation is read-only, whether authentication or a previously enabled database is required, or what the response format includes. This is a significant transparency 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, front-loaded sentence that wastes no words. Every part contributes directly to understanding the tool's purpose, with no filler or repetition.

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 tool is simple with one well-documented parameter and no output schema, so the description partially fills the gap by mentioning 'tables and columns.' However, it does not clarify the structure of the response (e.g., list of objects) or any prerequisites/dependencies (e.g., database must be enabled), leaving moderate room for ambiguity.

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 schema covers 100% of the parameter documentation with a clear description ('App ID or subdomain slug'), so the baseline is 3. The tool description does not add any additional parameter meaning beyond that, but none is needed given the high schema coverage.

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 uses the specific verb 'Get' alongside a clear resource: 'database schema (tables and columns) for an app's database.' This precisely states what the tool does and differentiates it from database_query (which queries data) and database_status (which checks status).

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 when to use the tool (when you need to know an app's table/column structure) but does not explicitly state exclusions or alternatives. For instance, it doesn't mention that database_query is for querying data or that enable_database must be called first. However, the purpose is clear enough to infer the primary use case.

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