Behavior1/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It fails to mention that this tool modifies an existing worksheet, whether it is destructive, requires specific permissions, or how it interacts with other configurations. The description is too brief.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is only one sentence long, which is concise, but it sacrifices clarity and completeness. It does not front-load key information or explain what 'configure' means. The sentence is too vague to be considered effective.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the high complexity (29 parameters) and no annotations or parameter descriptions, the description is severely inadequate. It does not explain the tool's effect, return value (output schema exists but not referenced), or how to use it effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no parameter-level information beyond the schema titles. With 29 parameters, the description must compensate, but it does not explain any of them. The baseline of 1 is appropriate, but 2 because the schema titles provide some minimal meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'Configure a dual-axis chart composition' which gives a general sense of the tool's purpose. However, it lacks specificity about what 'configure' entails and does not differentiate from sibling tools like 'configure_chart' or 'configure_worksheet_style'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as 'configure_chart' or 'configure_worksheet_style'. There is no mention of prerequisites, context, or conditions for appropriate use.

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