file_write

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

Without annotations, the description covers essential behaviors: creates intermediate directories and restricts to workspace root. However, it does not disclose whether the file is overwritten or appended, nor error handling details.

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 concise, front-loaded, and uses simple bullet-style args with no redundant information, making it efficient for an agent.

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?

For a simple two-parameter tool with an output schema, the description covers input behavior well. It could mention overwrite semantics, but is otherwise complete for typical usage.

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?

With 0% schema coverage, the description compensates by defining both parameters: 'path' as relative path and 'content' as text content, adding meaning beyond the bare schema titles.

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 'Write content to a file' with relative path, specifies workspace root confinement, and distinguishes from sibling tools like file_read, file_delete, and file_move.

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 implies usage for writing files and creating intermediate directories, but lacks explicit guidance on when not to use or alternatives, such as when to prefer file_move or when read-only is needed.

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