getBatchAftermarketQuote

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

Annotations provide readOnlyHint and idempotentHint. Description adds context on returned fields (bid, ask, volume). Does not mention time-dependency or rate limits, but adequately supplements annotations.

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 with no fluff. First sentence states purpose and source, second adds returned data. Efficient and front-loaded.

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?

Low complexity tool (1 param) with annotations covering safety. Description reasonably covers purpose and data returned. Lacks explicit temporal context (e.g., 'only available during post-market hours') which could affect usability, but overall 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?

Schema has 100% coverage with clear description of 'symbols' parameter. Description does not add new parameter-level insights beyond confirming multiple stocks. Baseline 3 is appropriate.

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?

Clearly states it retrieves real-time aftermarket quotes for multiple stocks. Differentiates from siblings like getAftermarketQuote (singular) and getBatchQuotes (regular session) by specifying 'aftermarket' and 'batch'.

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?

Implies usage for aftermarket multi-stock quotes but lacks explicit guidance on when to use vs alternatives like getAftermarketQuote or getBatchQuotes. No 'when not to use' or direct sibling comparison.

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