Latest Economic Indicators

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

Annotations cover only readOnlyHint=true, and the description adds genuinely useful behavior beyond that: the row shape (latest stored observation + date + previous observation + change), the caveat that values are 'latest stored' and freshness must be verified via the Latest Date column, and the fact that it returns a full macro snapshot rather than a single series.

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?

Three sentences, front-loaded with the scope and categories before the row-format detail. Nearly every clause earns its place; only the final 'Returns a snapshot of current macro conditions' is mildly redundant with the opening sentence.

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 and only a readOnlyHint annotation, the description carries the burden well by describing the returned columns and freshness semantics. It is close to complete, missing only guidance on breadth vs single-series siblings and any note on whether results are paginated or cached.

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 optional category parameter is fully documented with its allowed values, so the schema does the heavy lifting. The description restates the category list but adds no filtering syntax, default behavior, or format detail beyond it, so baseline 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?

States a specific verb and resource (get latest values for economic indicators) and enumerates the covered categories, so the scope is unambiguous. It does not, however, name or contrast itself with the nearby siblings GetEconomicIndicator and SearchEconomicIndicators, leaving the agent to infer that this is the breadth/snapshot variant.

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 description never states when to pick this over GetEconomicIndicator or SearchEconomicIndicators, nor any prerequisites. The only guidance is interpretive ('check the Latest Date column for freshness'), which helps read results but not select the tool.

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