insert_file_content

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

No annotations are present. The description omits behavioral details such as what happens if the file does not exist, if the row index is out of range, or whether the operation can be reversed. The return value is vaguely described as 'Operation result information'.

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 short and begins with the main purpose, then lists parameters in a clear format. However, the docstring-style repetition of parameter info could be more streamlined.

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 the lack of annotations and output schema, the description should provide more context about return values, error behavior, and edge cases. It only covers basic parameter semantics, leaving gaps in understanding how the tool behaves in practice.

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?

With 0% schema description coverage, the description compensates by explaining each parameter's purpose, including that 'row' and 'rows' are 0-based. It also notes that 'content' can be a string or JSON object, adding value beyond the schema's type string.

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 ('Insert content') and the resource ('at specific row(s) in a file'). This is distinct from sibling tools like 'write_file' (overwrite) or 'update_file_content' (modify existing content).

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?

The description provides no guidance on when to use this tool over alternatives such as 'write_file' or 'update_file_content'. It does not mention prerequisites or scenarios where insertion is appropriate.

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