write_file

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

With no annotations, the description must carry the behavioral burden. It discloses that parent directories are created automatically, that overwrite=False causes failure when the file exists, and that it returns the path and bytes written. It still omits permission requirements and broader failure modes.

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?

Front-loaded purpose followed by tightly structured Args and Returns sections. Every sentence carries useful information with no filler.

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 3-parameter write tool with no annotations, no output schema, and 0% schema coverage, the description is largely complete: it covers behavior, parameter meanings, and return value. Minor gaps remain around permissions, explicit default overwrite behavior, and non-overwrite failure modes.

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%, so the description must compensate. It documents all three parameters: path is workspace-relative with automatic parent creation, content is UTF-8 text, and overwrite=False prevents overwriting. It does not explicitly state the default overwrite value, though the schema provides it.

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?

States a specific verb and resource: 'Create or overwrite a text file inside the workspace.' This clearly distinguishes it from append_file and read_file by emphasizing full write/overwrite semantics.

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 explicit guidance on when to use this tool versus append_file, or when overwriting is appropriate. The overwrite parameter hints at some behavior, but alternatives and exclusions are left to inference.

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