create_file

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the action without explaining side effects, prerequisites, return values, or error conditions. It does not describe what creating a file entails beyond the literal action.

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 concise sentence with no redundancy or fluff. It is appropriately short for the tool's simplicity and every word contributes to the core purpose.

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?

While the tool has only three parameters and a clear purpose, the description omits any behavioral or contextual detail such as return value, prerequisites, permissions, or side effects. The schema covers parameters but not usage context. Given no output schema or annotations, the description is under-specified for an agent to understand the tool's full behavior.

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 provides 100% coverage of the three parameters with descriptions, so the baseline is 3. The description adds no additional meaning beyond the schema; it merely restates that a file is created in a project, which is already encoded in the parameter names and descriptions.

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 identifies the action (create) and resource (new file), and scopes it to a project, distinguishing it from sibling tools like list_files, get_file, rename_file, and delete_file. It lacks explicit mention of the required projectId/name parameters, but those are in the schema, so the purpose itself is unambiguous.

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 on when to use this tool vs alternatives. The description simply states what it does, with no mention of context such as requiring an existing project or distinguishing from create_project. There are no exclusions or alternative tool references.

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