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

No annotations are provided, so the description carries full burden. It mentions 'release flags' but does not explain what they mean, nor does it disclose data source, update frequency, or behavior (e.g., real-time vs. cached). Minimal but not misleading.

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?

Single sentence with 11 words, front-loaded with core purpose and specific examples. No fluff; every word earns its place.

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 tool with no output schema, the description is mostly sufficient by naming the indicators. It could be improved by briefly noting the output format or that it's a snapshot, but the simplicity keeps it adequate.

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?

There are zero parameters and schema coverage is 100% (empty). The description adds meaning by listing the types of indicators included (CPI, NFP, U3, oil), which provides semantic value beyond the empty schema.

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 the tool provides 'Latest US macro indicators' and lists specific indicators (CPI/NFP/U3/oil) with release flags. The verb 'get/retrieve' is implied, and it distinguishes itself from sibling tools by specifying a focused set of economic indicators.

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 US macro data but provides no explicit when-to-use or when-not-to-use guidance. With zero parameters, the tool is straightforward, but no alternatives or exclusions are mentioned relative to siblings like 'calendar' or 'context'.

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