get_website_charts

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

No annotations are provided, so the description bears the full behavioral burden. 'Get' implies a read operation, but the description does not disclose permissions, time-range defaults, aggregation behavior, return shape, pagination, or rate limits.

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 single sentence is front-loaded and wastes no words. However, its brevity reflects under-specification rather than efficient completeness.

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 four parameters, no annotations, no output schema, and 0% schema description coverage, the description is far too thin. It does not explain the time-range parameters, timezone handling, expected chart output, or how this differs from other analytics tools.

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%, yet the description only repeats the website limit already encoded as maxItems=20. It provides no meaning for startAt, endAt, or timezone, leaving half the parameters undocumented in both schema and description.

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?

States a specific verb and resource: get chart data for websites. The 'up to 20 websites' scope is clear, but the description does not distinguish this from sibling chart/stat tools such as get_link_charts, get_pixel_charts, get_revenue_chart, get_stats, or get_metrics.

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?

Provides no guidance on when to use this tool versus the many sibling analytics and chart tools. It also gives no prerequisites, exclusions, or context about which chart data is returned.

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