Dashboard

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds theme listings and customization details but does not disclose any additional behavioral traits (e.g., data source expectations, limitations). Minimal value added beyond 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?

Description is a single paragraph that front-loads the main purpose and lists themes efficiently. It is concise, though the lengthy theme list could be shortened or placed in schema. Overall well-structured.

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 parameters, nested objects), the description explains dashboard components and theming adequately but omits details about layout, grid behavior, and chart-specific options that are only in schema. With no output schema, more could be added to cover return format.

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 descriptions cover 100% of parameters. The description provides a list of themes and notes mix-and-match customization, but this largely echoes schema information. Baseline 3 is appropriate as the description adds marginal extra meaning.

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?

Description explicitly states 'Render a full dashboard with KPI cards, charts, and optional hero metric', clearly identifying the verb (render) and resource (dashboard). It contrasts with sibling single-chart renders by specifying it produces a composite dashboard.

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 explicit guidance on when to use this tool versus alternatives. The description implies it's for full dashboards, but does not provide criteria for choosing it over individual chart renders or other composite tools. Usage is implicit rather than prescriptive.

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