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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create a dashboard' implies a write/mutation operation, but the description doesn't mention required permissions, whether this creates an empty dashboard or requires configuration, what happens on success/failure, or any rate limits. For a mutation tool with zero annotation coverage, this leaves critical behavioral aspects unspecified.

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 extremely concise ('Create a dashboard') but this brevity comes at the cost of being under-specified rather than efficiently informative. While it's front-loaded with the core action, the single phrase fails to provide necessary context. Conciseness should not sacrifice completeness for a tool that likely has important behavioral nuances.

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 this is a mutation tool (create operation) with no annotations, no output schema, and multiple similar sibling tools, the description is severely incomplete. It doesn't explain what gets created, under what conditions, what the expected outcome is, or how it differs from other dashboard creation tools. The agent would struggle to use this tool correctly without additional 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 input schema has 0 parameters with 100% description coverage (empty schema). Since there are no parameters to document, the description doesn't need to compensate for any gaps. The baseline for 0 parameters is 4, as the description cannot reasonably add parameter semantics beyond what the schema already indicates (no parameters required).

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 'Create a dashboard' is a tautology that merely restates the tool name 'create_dashboard_v1'. While it indicates the verb (create) and resource (dashboard), it provides no specificity about what kind of dashboard, in what context, or what distinguishes it from sibling tools like 'create_dashboards' or 'create_dashboard_lists_manual_dashboards'. This minimal statement fails to differentiate the tool's purpose from alternatives.

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 provides absolutely no guidance on when to use this tool versus alternatives. With multiple sibling tools that also create dashboards (e.g., 'create_dashboards', 'create_dashboard_lists_manual_dashboards'), the agent has no indication whether this is a simplified version, a specific API version, or intended for particular use cases. No prerequisites, context, or exclusions are mentioned.

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