remove_first_n_characters

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

With no annotations, the description carries full behavioral burden. It only notes the return value on success, but doesn't disclose failure behavior, whether the original file is modified, permissions required, or how optional parameters (_range, worksheet) affect the operation. This is a significant gap for a mutation tool.

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 concise and front-loaded, with only two sentences and no fluff. However, brevity sacrifices critical details, making it efficient but under-specified.

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 tool with 4 parameters and no annotations, the description is incomplete. It lacks parameter context, preconditions, default behaviors, and edge-case handling. The presence of an output schema partially covers return values, but overall the description is inadequate for safe and correct invocation.

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% and the description provides no parameter meanings. It hints at 'first N' mapping to 'number' and 'specified range' to '_range', but fails to explain file_token, worksheet, or the expected format for _range. The description adds essentially no value over the raw schema.

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 tool's action: removing the first N characters from each text cell in a specified range. This is specific and distinguishes it from related tools like remove_last_n_characters and trim_text variants.

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 similar alternatives (e.g., remove_before_text for variable-length removal). It doesn't mention prerequisites like obtaining a file_token from upload_file. The description only states what it does, not when it should be chosen.

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