Analyze Database Size

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

The description indicates it returns size information but lacks details on exactly what is returned, whether it has side effects (likely none), or any required permissions. With no annotations, the burden is higher, but the description is adequate but minimal.

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, clear sentence with no wasted words. However, it could be slightly more structured or expanded to include key details.

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 simple structure (one optional parameter, no output schema), the description is adequate but not comprehensive. It explains the general output but not the exact return format or additional context an agent might need.

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 input schema has one optional parameter (connectionName) with a clear description. The tool description adds no further meaning about the parameter, but since schema coverage is 100%, the baseline is 3.

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's purpose: retrieving comprehensive database size information, specifically data and log file sizes. It distinguishes from sibling analyze_* tools that focus on other aspects like constraints or index usage.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions, leaving the agent to infer usage from the name alone.

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