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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that it returns publisher-gate warnings and freshness fields, which is useful, but it doesn't explain caveats like staleness thresholds or what a warning implies. Modest added context over annotations.

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 sentences, front-loaded with what's returned, followed by the use case. Tight and readable, though the parenthetical field list is dense.

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-param read-only tool with no output schema, the description gives a reasonable picture but leaves the return shape informal and doesn't clarify relationship to bank_status or how to interpret publisher-gate warnings in practice.

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?

Zero parameters, so baseline is 4. The description correctly implies no inputs are needed and instead describes the returned dimensions.

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 resource (dataset freshness) and enumerates the returned fields (last decision, next meeting, days to it, resolvability) plus publisher-gate warnings. It's clear what the tool surfaces, though it doesn't explicitly distinguish itself from the closest sibling, bank_status.

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 gives a clear usage context: 'Use to judge how far to trust an answer.' That's a strong when-to-use signal, but it doesn't name alternatives like bank_status or resolution_sources or state exclusions.

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