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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is fully covered. The description adds one useful behavioral detail: each returned dashboard includes its widget count. It says nothing about ordering, pagination, or whether an empty base returns an empty array.

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?

Extremely short and front-loaded, zero filler. However, it is a sentence fragment rather than a statement of action, which slightly undercuts clarity for such brevity.

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 no output schema, the description bears full responsibility for describing the return value, and only 'widget counts' is disclosed — nothing about other dashboard fields, result shape, or ordering. For a listing tool with a 0%-documented required parameter, this is under-specified.

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 0%, so the description must carry the weight; 'of a base' at least tells the agent baseId scopes the listing, but there is no mention of the ID format or whether it is required. Marginal compensation for the coverage gap.

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 fragment names the resource (dashboards) and scopes it to a base, plus mentions widget counts. But it omits a verb like 'list/return' and gives no signal distinguishing it from the sibling get_dashboard or create_dashboard beyond the name.

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 indication of when to use this versus get_dashboard for a single dashboard, or versus describe_base for base structure. The agent must infer from the tool name alone.

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