project.create_file

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

With no annotations, the description bears full responsibility for disclosing behavioral traits. It only states that the tool creates a file, but does not mention whether it overwrites existing files, requires authentication, has size limits, or what happens on failure. The description is insufficient 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.

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

The description is a single, front-loaded sentence that is very concise. However, it sacrifices essential details for brevity. While not verbose, it is incomplete, which reduces its effectiveness.

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 tool has 5 parameters, no output schema, no annotations, and 0% schema description coverage, the description is severely inadequate. It does not explain return values, side effects, constraints, or parameter relationships. The agent would be left with many unknowns.

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 0%, and the description adds meaning only for 'data_base64' (it mentions base64 data). The other four parameters (name, folder_id, project_id, description) are not explained; the agent must rely on their names. The description does not compensate for the lack of schema 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 uses a specific verb ('Create') and resource ('project file') with a clear input format ('from base64 data'). It uniquely identifies the tool's purpose among siblings like project.create and project.create_folder, which create projects and folders respectively.

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, no prerequisites, no error conditions, and no mention of context (e.g., whether the project must already exist). The agent must infer usage from the parameter names alone.

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