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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states what the tool does at a high level without revealing any behavioral traits such as whether it modifies existing charts, creates new ones, requires specific permissions, has side effects, or how it interacts with other tools. This is inadequate for a tool with 29 parameters.

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 extremely concise with a single sentence. It's front-loaded with the core action ('Configure') and resource ('dual-axis chart composition'), though this brevity comes at the cost of being under-specified given 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?

Given the high complexity (29 parameters, 1 required), no annotations, 0% schema description coverage, and the presence of an output schema, the description is completely inadequate. It doesn't explain what the tool does in practical terms, how to use it, what the parameters mean, or what behavior to expect. The output schema existence doesn't compensate for these fundamental gaps.

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%, meaning none of the 29 parameters have descriptions in the schema. The tool description provides no information about any parameters, not even the required 'worksheet_name' or what the dual-axis configuration entails. This fails to compensate for the complete lack of schema documentation.

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 'Configure a dual-axis chart composition' states the general purpose (configuring a dual-axis chart) but is vague about what specifically it does. It doesn't distinguish this tool from sibling tools like 'configure_chart' or 'configure_chart_recipe', nor does it specify what resources it acts upon beyond the generic 'chart composition'.

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 provides no guidance on when to use this tool versus alternatives. With many sibling tools related to chart configuration (e.g., 'configure_chart', 'configure_chart_recipe', 'add_reference_line'), there's no indication of when this specific dual-axis configuration tool is appropriate or what prerequisites might be needed.

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