create_chart

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

The description only reveals that the domain comes from the first source column, but fails to disclose whether the tool modifies data, requires permissions, or has side effects. With no annotations, the burden is high, and this is insufficient.

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 sentence that is front-loaded, but it is too brief to be considered efficient given the tool's complexity. It sacrifices substance for brevity.

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 8 parameters, 3 required, no schema descriptions, and no output schema details, the description is woefully incomplete. An agent cannot reliably invoke this tool without additional documentation.

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 description does not explain any of the 8 parameters, and the schema has 0% coverage. Users are left to infer the meaning of title, chart_type, anchor_cell, etc., without any added context.

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 'native chart', and adds specificity with 'using the first source column as its domain.' This distinguishes it from sibling tools like create_pivot_table and other non-chart tools.

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?

No guidance is provided on when to use this tool versus alternatives, nor are there any prerequisites or exclusion criteria mentioned. The description lacks context for decision-making.

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