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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds 'real-time and historical' context, which is consistent and non-contradictory. However, it does not disclose additional behavioral traits like response format or rate limits, but annotations cover the core safety aspects.

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: first states the action with examples, second adds purpose. No filler words; front-loaded with key information. Highly efficient.

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 simple tool (3 params, no output schema), the description adequately covers input and general purpose. It hints at output usage ('measure economic performance') but does not specify return format. Slightly incomplete but sufficient for the complexity level.

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?

Input schema has 100% description coverage, with all three parameters documented. The description adds indicator examples (GDP, unemployment, inflation) but does not introduce new semantic information beyond the schema. Baseline score of 3 is appropriate as schema does the heavy lifting.

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's function: accessing real-time and historical economic data for key indicators like GDP, unemployment, and inflation. It specifies the source (FMP Economic Indicators API) and differentiates from sibling tools focused on stocks, forex, or news by targeting macroeconomic data.

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 provides an application context ('measure economic performance and identify growth trends') but lacks explicit guidance on when to use this tool over alternatives or when not to use it. No mention of exclusions or comparisons with siblings.

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