remove_text_characters

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

With no annotations, the description carries the transparency burden. It discloses the exact characters removed, preservation of other characters, and return value (True on success), but does not mention side effects, permissions, or how the file is updated.

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 sentences front-load the core operation and add only useful details about preservation and return value. No redundant information.

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 tool has an output schema, return values are covered, but the description omits behavior when optional parameters are absent (e.g., default range) and how file_token relates to prior upload. These gaps make it adequate but not fully complete.

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 schema provides no descriptions for the three parameters, and the description only hints at range and worksheet ('within a specified range of a worksheet') without explaining their format or the required file_token. This leaves the required parameter largely unexplained.

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 explicitly states it removes all alphabetic characters (A-Z, a-z) from cells in a specified Excel range, which clearly differentiates it from sibling tools like remove_numeric_characters or remove_symbols. It also specifies that numbers, symbols, and whitespace are preserved.

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 implies the tool is for stripping letters while keeping other character types, but it does not explicitly mention alternatives or when not to use it. It lacks comparative guidance against sibling removal tools.

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