write_files

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

No annotations are provided. The description mentions 'using an in-memory archive' which hints at ephemeral storage, but lacks details on mutation behavior, permissions, error handling, or what happens on overwrite. The absence of behavioral disclosure beyond the one phrase limits agent understanding.

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 sentence, concise but overly sparse. It lacks necessary details, making it insufficient rather than optimally concise.

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 three parameters, a batch file operation, and no output schema provided, the description is severely incomplete. It omits the batch nature, overwrite behavior, session requirement, and return value. The tool is more complex than the description implies.

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 no information about the parameters (path, content, overwrite, session_id). It does not explain the required session_id, the meaning of overwrite, or the structure of files. This leaves the agent without parameter guidance.

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 (write) and resource (UTF-8 text files beneath /workspace). It distinguishes from sibling tools like list_files and read_file. However, it does not mention the batch operation (array of files) or the overwrite capability, which would further clarify the tool's scope.

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?

No guidance on when to use this tool versus alternatives like create_sandbox or run_javascript. There is no mention of prerequisites, context, or when not to use it.

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