super_db_create_pool

Create a new database pool in SuperDB to organize and sort data for efficient querying and management.

Instructions

Create a new pool in a SuperDB database.

Behavior2/5

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 states 'Create' which implies a write/mutation operation, but it doesn't cover permissions needed, whether the operation is idempotent, error handling, or what happens on success (e.g., returns a pool ID). This leaves significant gaps for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence that directly states the tool's purpose without any unnecessary words. It's front-loaded and efficiently communicates the core action, making it highly concise and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that this is a mutation tool (creating a pool) with no annotations and no output schema, the description is incomplete. It doesn't address behavioral aspects like side effects, return values, or error conditions, which are critical for safe and effective use by an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds no parameter semantics beyond what the input schema provides. Since schema description coverage is 100%, the baseline score is 3. The description doesn't explain how parameters interact (e.g., if 'orderBy' affects pool creation) or provide additional context, so it doesn't exceed the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Create') and resource ('new pool in a SuperDB database'), making the purpose immediately understandable. However, it doesn't differentiate this tool from potential sibling tools like 'super_db_load' or 'super_db_list', which might also involve pool operations, so it doesn't reach the highest score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. With siblings like 'super_db_load' and 'super_db_list' that might relate to pools, there's no indication of prerequisites, context, or exclusions for using this creation tool.

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