create_dashboard

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

The description adds the behavioral context of requiring WRITE_ENABLED=true, which is not in annotations. It confirms the write operation (consistent with readOnlyHint=false) but does not elaborate on other effects, such as whether the dashboard is immediately available or any side effects.

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, front-loaded sentence with no unnecessary words. It conveys the core purpose and a key requirement efficiently.

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?

While the tool is simple and annotations cover some behavioral hints, the description lacks information about the return value (common for create tools) and does not summarize the parameters. Given the absence of an output schema, some guidance on what to expect after creation would improve completeness.

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 input schema already provides descriptions for all 4 parameters (100% coverage), so the description does not need to add parameter details. It adds no extra meaning beyond the schema, meeting the baseline.

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 action ('Create') and the resource ('a new Performance Analytics dashboard'), making the tool's purpose unambiguous. Among siblings like 'create_report' and 'update_dashboard', the name and description sufficiently differentiate it.

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 includes a specific prerequisite ('requires WRITE_ENABLED=true'), which guides the agent on when this tool can be used. However, it does not mention when to prefer this tool over alternatives or provide any exclusions.

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