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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real scope boundaries beyond that: the output is point-in-time only, it will not extrapolate trends, and it is not a legal certification — useful guardrails that set expected output limits.

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?

Two short sentences with the capability stated first and the caveat second — front-loaded and free of padding. The second sentence is slightly awkward in its negative framing but earns its place as a scope disclaimer.

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 report-generating tool with two fully undocumented parameters and no output schema, the description should say what the report contains, what the comparison baseline is, and how the filters behave. It covers only the temporal/legal framing, leaving the actual invocation semantics unexplained.

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 0% for both `state` and `locationIds`, so the schema gives an agent nothing but types and formats. The description does not mention either parameter, explain whether locationIds narrows the report scope, or state what happens when both are omitted (0 required params implies a default whole-tenant scope that is never confirmed).

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?

"Generate a structured point-in-time comparison report" states a specific verb and output artifact, but never says what is being compared or scoped (compliance status by state/location). Against siblings like get_weekly_compliance_report, get_compliance_trend, and get_location_compliance_summary, an agent cannot tell which report tool to pick from the description alone.

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?

There is no explicit when-to-use, no prerequisites, and no alternatives named. The phrase "No unsupported historical trends" faintly gestures at get_compliance_trend being the trend tool, but it never names it, so the routing decision is left entirely to inference.

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