getAllIndexQuotes

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

The annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety and idempotency profile is covered. The description adds that quotes are real-time and that the tool returns multiple indexes in a single request, but it does not discuss rate limits, authentication, or return-field behavior.

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 appropriately short and front-loads the purpose, but the second sentence largely restates the first with marketing phrasing such as 'broad view of the financial markets.' It is functional but not maximally economical.

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 read-only tool with one optional parameter and annotations covering behavior, the description is adequate but lacks specifics about what 'all indexes' includes and how the short parameter changes the response. It covers the main purpose without fully describing scope boundaries.

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 parameter 'short' is already documented in the schema with its default. The description adds no additional meaning about the parameter, so the baseline of 3 applies when the 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 states a specific verb and resource: it provides real-time quotes for stock indexes, and it scopes the tool to multiple indexes in a single request. This makes the tool distinguishable from single-index quote tools, though it does not explicitly name any sibling alternative.

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 the tool is for getting a broad market view across many indexes in one request, which gives a clear use case. However, it does not explicitly say when to use this instead of siblings like getIndexQuote or getIndexQuotes, and it provides no exclusions.

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