chart

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

No annotations are provided, so the description carries full burden for behavioral disclosure. The single word 'chart' reveals nothing about whether this is a read/write operation, authentication requirements, rate limits, side effects, or expected behavior. This is completely inadequate for a tool with unknown functionality.

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?

While technically concise with a single word, this represents severe under-specification rather than effective brevity. The description fails to convey any meaningful information about the tool's purpose or usage, making it functionally useless despite its 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?

Given the complete lack of annotations, no output schema, and a description that provides zero functional information, this is completely inadequate. The tool's purpose, behavior, and usage remain entirely mysterious despite having 78 sibling tools that could provide context.

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 tool has zero parameters with 100% schema description coverage, so no parameter documentation is needed. The description doesn't mention parameters, which is appropriate. A baseline of 4 is assigned since no parameters exist to document.

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?

Tautological: description restates name/title.

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 offers absolutely no guidance on when to use this tool versus alternatives. With 78 sibling tools and no context provided, there is no indication of appropriate use cases, prerequisites, or differentiation from other tools.

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