write_file

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

The description does not disclose important behavioral traits such as whether the file is overwritten, permissions required, or error handling. Without annotations, the description carries the full burden, and it is insufficient.

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, to-the-point sentence with no wasted words. It earns its place by conveying the core action concisely.

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 file write tool, the description lacks completeness. It does not mention return values, overwrite behavior, or any constraints, making it less useful for an AI agent to fully understand the tool's effect.

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% for both parameters, so the description adds no extra meaning. Baseline 3 is appropriate; the schema already documents path and content adequately.

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 'Write content to a file' clearly states the verb 'Write' and the resource 'content to a file', distinguishing it from sibling tools like read_file and delete_file. However, it does not specify whether it overwrites or appends, which would add more precision.

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 is given on when to use this tool versus alternatives. An explicit mention of use cases or exclusions (e.g., when to use deploy instead) is missing.

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