create_file

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

With no annotations, the description carries full behavioral burden, but it only restates the tool's name ('create new file') and adds the vague precondition of an 'active workspace'. It fails to disclose behavior on existing files, permission requirements, error handling, or return values.

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?

At seven words, the description is under-specified rather than concise. A tool with three required parameters needs more detail about preconditions, parameter usage, and outcomes. The single sentence does not effectively front-load critical information.

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 no annotations, no output schema, and three required parameters, the description is severely incomplete. It omits any discussion of error conditions (e.g., file already exists, invalid workspace), workspace requirements, or return behavior, making it inadequate for safe invocation.

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 provides no explanation for any of the three required parameters (workspace_id, path, content). It does not compensate for the lack of schema information, leaving agents to guess parameter formats and semantics.

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 states a clear action (create), resource (file), and location (active workspace). It is distinguishable from siblings like edit_file and delete_file by the verb 'create' and the word 'new', though it does not explicitly name alternatives.

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?

It mentions 'active workspace' as a condition, but does not explain when to use this tool versus alternatives such as create_project or edit_file. There are no explicit when-to-use or when-not-to-use instructions, leaving the agent without guidance on selection.

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