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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds that the dashboard bundles many sub-sections, but says nothing about return format, size, pagination, or data freshness. With annotations doing the safety work, this is a moderate addition.

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?

A single front-loaded sentence enumerating the roll-up contents. It is dense but every clause names a distinct data section the agent can expect; no filler.

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?

For a read-only aggregation tool with no output schema and full schema coverage on its one param, the description does well by enumerating the returned data sections an agent needs to judge relevance. The main omission is guidance on choosing it over narrower siblings.

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 description coverage is 100% and the single 'state' parameter is fully documented in the schema (2-letter code, territories). The description adds no parameter-level detail beyond what the schema already provides, so the baseline of 3 applies.

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 states a specific verb ('Returns') and resource ('the complete picture for one US state') and then enumerates the exact contents, making it clearly distinguishable from siblings like get_states_summary or find_service_deserts that cover narrower slices.

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 word 'complete' and the aggregation hint suggest this is the broad single-state roll-up, but there is no explicit statement of when to use it versus the many narrower siblings (find_service_deserts, get_states_summary, get_veteran_resource_stats). Usage is implied rather than specified.

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