create_gdextension

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 only states that the tool creates a config file, but does not disclose whether it overwrites existing files, creates parent directories, or has other side effects. The description is too brief to convey risks or operational behavior.

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 sentence with no fluff or redundancy. It efficiently communicates the core purpose without wasting words, which is ideal for a tool of this simplicity.

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 absence of annotations and the simplicity of the tool, the description is incomplete. It does not mention potential overwrite behavior, whether directories are created, or the return value. The schema covers parameters, but the description lacks sufficient context for safe and correct usage, especially for a file-writing operation.

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 description coverage is 100% (all three parameters have descriptions with examples), so the schema fully documents each parameter. The description itself adds no additional parameter semantics, but the baseline score of 3 is appropriate since the structured data fills the gap.

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 a specific verb ('Create') and identifies a clear resource ('.gdextension config file'), distinguishing it from siblings like read_gdextension or other creation tools. It is direct and unambiguous about what the tool accomplishes.

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 no guidance on when to use this tool versus alternatives, such as read_gdextension for reading or write_resource for generic resource writing. There are no prerequisites, exclusions, or context indicating the appropriate scenarios for creation.

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