files_write_config_file

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

The description discloses YAML validation (and how to skip it) and automatic parent directory creation. However, it does not indicate that the tool overwrites existing files, potential error conditions, or file encoding details. With no annotations, this is a partial disclosure.

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?

Two concise sentences front-load key information. No unnecessary words, but structure could be improved with a bullet list or separate behavior notes.

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 file write tool with an output schema, the description covers basic usage (write, validate, create dirs) but omits overwrite behavior, path scope, and error handling. Adequate but not fully comprehensive.

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?

The input schema has 0% description coverage. The description adds value by explaining the 'validate_yaml' parameter but does not describe 'relative_path' (relative to what?) or 'content' (expected format). This leaves significant gaps.

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 states 'Write content to a config file' which clearly identifies the verb and resource. It also mentions YAML validation and directory creation. However, it does not explicitly distinguish from sibling 'files_append_to_config_file' by specifying overwrite behavior, leaving minor ambiguity.

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 provided on when to use this tool versus alternatives like files_append_to_config_file or files_read_config_file. The description lacks explicit context for selection.

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