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

With no annotations, the description carries the full behavioral burden. It discloses what data the status call exposes and adds a valuable semantic caveat: the item count is not a count of all home-visit nursing billing requirements. It does not explicitly state output format or absence of side effects, but the status-report nature makes these less critical.

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 compact and front-loaded with the resource and purpose. Each sentence earns its place: what the status contains, a critical caveat about the item count, and the intended first action.

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 zero-parameter status tool with no output schema, the description lists all the report fields and the key interpretation caveat. It could be slightly clearer about what 'version' refers to, but overall an agent has enough information to invoke the tool correctly and understand its result.

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 tool has zero parameters and an empty input schema, so the baseline of 4 applies. There are no parameter semantics for the description to add or clarify.

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 identifies the tool as a database status report and enumerates its exact contents: version, item count, source provenance breakdown, unconfirmed requirements count, and unresolved discrepancies count. The closing instruction 'look here first' positions it as the overview entry point, distinguishing it from the more specific sibling tools.

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?

It explicitly instructs the agent to use this tool first ('まずここを見ること'), providing clear usage context. It does not name alternatives or state when not to use the tool, but the overview-versus-detail relationship to the sibling tools is implied.

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