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

Annotations already declare readOnly, idempotent, non-destructive, openWorld. The description adds domain-level behavior context: publication cadence (eight times a year), the 12-district structure, and the section breakdown, helping the agent set expectations for returned content. It does not describe error behavior or edition availability, keeping it short of a 5.

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?

Front-loaded correctly with the resource name, but the single long sentence relies on nested parentheticals (twelve district names, four section names) that make it dense and slightly hard to scan. Every element is relevant, yet the packing into one sentence hurts readability.

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 0 required params, rich annotations, and no output schema, the description supplies the domain framing (cadence, district/section structure) an agent needs. It stops short of describing what a returned report actually contains or how editions map to time ranges, leaving a small gap.

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 coverage is 100% (baseline 3), and the description adds real meaning by enumerating all 12 district names and the section structure, reinforcing the valid values for the 'district' parameter and clarifying what 'edition' selects. It goes beyond the schema's terse parameter docs.

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+resource (Federal Reserve Beige Book) with precise scope: the national summary or one district's report, split into named sections. An agent can immediately distinguish this from siblings like fed_speeches or fomc_minutes, which cover different Fed publications.

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 three example questions ('what does the latest Beige Book say about the Dallas district', 'Beige Book labor market conditions', etc.) clearly imply the intended use context. However, it never names the alternative Fed-content siblings (fomc_minutes, fed_speeches) to route the agent when the user's request is ambiguous.

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