create_chart_from_series

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

Annotations already declare destructiveHint=true, but the description adds no explanation of what destructive action occurs (e.g., overwriting an existing chart or modifying the workbook). It only restates the core function, offering no additional behavioral context beyond the annotation.

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 with no wasted words. It effectively communicates the core purpose, though it's slightly under-specified for the tool's complexity.

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?

With 13 parameters, no output schema, and zero parameter-level descriptions, this one-sentence description is completely inadequate. It doesn't explain how to define series, what chart types are supported, where charts are placed, or what the return value is. The complexity demands far more detail.

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 explain parameters. It only refers to 'explicit series definitions' and 'non-contiguous ranges,' hinting at the 'series' and 'categories_range' parameters but leaving the other 11 parameters (e.g., filepath, sheet_name, chart_type, placement) unexplained. This is insufficient for a 13-parameter 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 verb ('Create') and resource ('chart from explicit series definitions'), with a specific scope ('non-contiguous ranges') that distinguishes it from the sibling tool 'create_chart'. It immediately conveys what makes this tool unique.

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 creating charts with explicit series or non-contiguous ranges, but it doesn't explicitly state when to prefer this over create_chart or other chart tools. It lacks clear alternatives or exclusion criteria.

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