trim_text_from_leading

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

No annotations are provided, so the description must disclose all behavioral traits. It mentions the operation and return value ('Returns True if the operation succeeds') but fails to explain whether the file is modified in place or a new token is generated, side effects, or permission requirements. 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 a single, front-loaded sentence that clearly states the action and includes a brief return-value note. There is no filler or redundant content, making it concise and well-structured.

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 4 parameters, no annotations, and no schema descriptions, the description needs to provide comprehensive context. It covers the high-level behavior but lacks critical details about input formats, file modification semantics, and error handling. The brevity leaves an agent guessing on how to properly invoke the tool.

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%, so the description must fully explain parameter meanings. It mentions 'specified leading characters' (trim_text) and 'specified range of a worksheet' (_range) but does not clarify the format of _range (e.g., 'A1:B10') or the precise nature of trim_text (single character vs. set). The required file_token and worksheet parameters are not described at all.

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 function: 'Removes specified leading characters only (from the beginning) of text values within a specified range of a worksheet'. This specific verb+resource+scope distinguishes it from sibling tools like trim_text_from_trailing, making the purpose unambiguous.

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 phrase 'only (from the beginning)' implies when to use this tool (for leading trims) but does not explicitly name alternatives or exclusion criteria. It provides implied usage guidance but lacks direct 'when to use vs. not use' statements.

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