get_macro_snapshot

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

Annotations already declare readOnlyHint, destructiveHint, and idempotentHint. The description adds useful context about the data coverage (countries and indicators) without contradicting annotations. It does not detail behavioral traits like filtering defaults or data freshness, but the annotations cover safety and idempotency.

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 short and front-loaded with the key purpose. However, it includes a redundant Vietnamese translation which adds length without value for an English-speaking agent. This slight inefficiency prevents a perfect score.

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?

Given the simplicity (one optional param, no output schema), the description adequately covers the what (indicators) and where (countries). It lacks details on output format or whether values are current/historical, but for a snapshot tool, this is sufficient.

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?

With 100% schema coverage, the input schema already describes the single parameter 'category' as 'Filter: vietnam, us, china, commodities.' The description does not add additional semantics beyond listing the indicators. Baseline 3 is appropriate.

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 states 'Vietnam + US + China macro indicators: GDP, CPI, interest rates, FX, gold, oil.' It specifies the resource and scope, distinguishing it from siblings like get_macro_playbooks or get_commodity_playbooks which likely provide analysis rather than raw snapshots.

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 implies usage for fetching macro data, but provides no explicit guidance on when to use this tool versus alternatives (e.g., get_macro_playbooks, get_commodity_playbooks). No exclusions or alternative suggestions are given.

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