Create Project File

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

Annotations declare readOnlyHint=false, consistent with creation. The description adds that it returns the created object on HTTP 201 and includes the API endpoint. This provides useful context beyond annotations, though it doesn't disclose potential constraints like file name uniqueness or overwrite 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?

Three sentences with front-loaded purpose. The API endpoint inclusion is slightly extraneous but not wasteful. Could be slightly more efficient by removing the redundant 'Documents' reference.

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?

No output schema exists, and the description mentions return of the created object but not its shape. With good annotations but lacking output schema, the description is adequate for a create tool with well-documented parameters, but misses error conditions or idempotency details.

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 coverage is 100%, so the description does not need to add much. It only mentions 'Required parameters: project_id' which is already in the schema. No additional semantic value beyond the parameter 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 states the action ('Create a new File') and resource ('in the specified Project'). It uses a specific verb and resource, though it inconsistently refers to 'Documents' instead of 'File' in a later sentence. Among many sibling tools like create_company_file and create_project_folder, it distinguishes by mentioning 'Project' and providing the API endpoint, but could more explicitly differentiate.

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 says 'Use this to create a new Documents' but provides no guidance on when not to use it or alternatives (e.g., for folders or file versions). It mentions the required parameter 'project_id' implicitly, but lacks explicit context for selection among siblings.

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