getCryptocurrencyShortQuote

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, which cover safety and idempotency. The description adds 'real-time' and 'current' but does not elaborate on data freshness, rate limits, or other behavioral traits beyond what annotations provide.

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 a single sentence that efficiently conveys purpose and scope. It is appropriately concise and front-loaded, though it could be slightly more precise about the output scope.

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 tool has one parameter, annotations, and no output schema, the description adequately explains the purpose and general output (prices, changes, volume). However, it lacks details on the exact fields returned, which would help the agent understand the response structure.

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?

The schema coverage is 100% for the single required parameter 'symbol', with a clear example 'BTCUSD'. The description does not add any additional parameter semantics or format guidance beyond the schema, so it meets the baseline for high coverage.

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 verb 'access' and resource 'real-time cryptocurrency quotes' and specifies it provides a 'concise overview' of prices, changes, and trading volume. It distinguishes itself from sibling tools like getCryptocurrencyQuote by indicating a shorter/simpler output, but does not explicitly differentiate.

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 no guidance on when to use this tool versus alternatives such as getCryptocurrencyQuote, getCryptoQuotes, or getCryptocurrencyBatchQuotes. No prerequisites or exclusions are mentioned, leaving the agent without context for selection.

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