write_file

Write content to any file, automatically escalating to sudo for protected paths to avoid permission errors.

Instructions

Write content to a file, escalating to sudo if the path is protected.

TDQS

A3.7/5.0
Behavior3/5

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

With no annotations provided, the description carries full burden. It discloses sudo escalation for protected paths, which is valuable. However, it does not mention overwrite behavior, file creation, or error handling, leaving gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded and contains only essential information. Every word earns its place with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given few parameters and no output schema, the description covers core purpose and a key behavior (sudo). However, it omits important details like whether the file is overwritten or appended, and what happens on failure, making it minimally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds context for the filename parameter (sudo escalation) but provides no additional semantics for the content parameter beyond the schema's 'File content.'

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'write content to a file' and clearly identifies the resource. It distinguishes from sibling tools like read_file (reading) and run_* (command execution) by core action. The mention of sudo escalation adds specificity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for writing files, but provides no explicit when-to-use or when-not-to-use guidance. It does not mention alternatives or exclusions, relying on sibling names for differentiation.

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