create_file_gdb

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

With no annotations provided, the description partially covers behavior: it mentions the prerequisite that the parent folder must be within a PathGuard allowed root and that it returns the created path. However, it does not disclose whether an existing geodatabase with the same name will be overwritten or if errors are raised for invalid names beyond the regex pattern.

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 two sentences: the first defines the operation and method, the second states use cases and constraints. Every sentence adds value, and the structure is front-loaded with the primary action.

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?

For a simple creation tool with two well-documented parameters, the description covers purpose, use context, a key constraint (PathGuard), and return value (path). An output schema exists (not shown) to cover return details. The only minor gap is the lack of clarification on overwrite behavior, but overall it is sufficient for this tool's complexity.

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 already provides detailed descriptions for both parameters (gdb_name with pattern and maxLength, parent_folder with absolute path requirement). The description adds the PathGuard constraint for parent_folder, but otherwise does not significantly enhance understanding beyond the schema.

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 verb ('Create') and resource ('file geodatabase') and lists specific use cases (scratch outputs, copied data, imports, analysis results). It distinguishes itself from sibling tools like create_feature_class by targeting the workspace itself rather than a dataset within.

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 explains when to use the tool ('prepare a workspace for scratch outputs...') and implies it's for creating a container rather than a feature class or other dataset. However, it does not explicitly mention when not to use it or compare to alternatives like create_feature_class, leaving some ambiguity.

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