Dashboard

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety. The description adds theme details but no further behavioral traits (e.g., error handling, performance). No contradiction with annotations.

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 concise, front-loaded with purpose, and efficiently lists themes. It could benefit from more structured formatting (e.g., bullet points), but the single paragraph is effective and free of fluff.

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 tool's complexity (11 params, nested objects, 100% schema coverage, no output schema), the description covers the main functionality and theming. Missing deeper details on layout/hero variants, but overall complete for a high-level render tool.

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 coverage is 100%, so baseline is 3. The description lists theme options and mix-and-match capability, adding minimal value beyond the schema's own parameter descriptions (which are already detailed).

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 'Render a full dashboard with KPI cards, charts, and optional hero metric in a responsive grid.' It distinguishes from sibling tools like single-chart renders by emphasizing the comprehensive dashboard output.

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 implies use for full dashboards but does not explicitly guide when to use this tool vs. individual chart tools. Sibling names hint at the distinction, but no direct 'when-not' or alternative references are provided.

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