Write file

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

Annotations already provide destructiveHint=true, so the description's 'overwrite' adds minimal transparency. It does not explain the overwrite parameter behavior, what happens to existing files, or required permissions.

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?

Single sentence, efficient, and front-loaded. However, it omits crucial details that would make the tool safer to use, such as the overwrite parameter's role.

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?

With 4 parameters, 0% schema coverage, and a destructive annotation, the description fails to provide sufficient context. It does not explain the overwrite behavior or the return output, assuming an output schema exists but not shown.

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 does not elaborate on any parameter. It only implies content is UTF-8. No details on path format, workspaceId usage, or overwrite 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?

Description clearly states the verb (create or overwrite), resource (UTF-8 file), and context (inside an open workspace). It distinguishes from siblings like file_edit (which modifies) and file_read (which reads).

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?

Implies usage within an open workspace but does not specify when to use this vs. file_edit or other alternatives. No explicit when-not or exclusion advice.

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