get_stock_latest_quote

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

There are no annotations, so the description carries the full burden. It only states retrieval and formatting, without disclosing data source behavior, default feeds, delay implications, or output formatting specifics. Minor credit is given for the word 'formats' hinting at output structure.

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, front-loaded sentence with no redundancy. It is concise and to the point, though it could include additional contextual guidance without becoming overly long.

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?

The output schema and rich parameter descriptions cover return values and parameter details, reducing the need for the description to explain them. However, the description lacks usage guidance and behavioral context relative to sibling tools, making it merely adequate with clear gaps.

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 input schema covers 100% of parameters with descriptive text, including enum values, defaults, and ISO currency details. The description adds no additional parameter semantics, so the baseline score of 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?

The description uses a specific verb ('retrieves and formats') and clearly identifies the resource ('latest quote for one or more stocks'). It distinguishes from historical or trade-focused siblings by focusing on 'latest quote', though it does not explicitly call out the alternative get_stock_quotes.

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?

No guidance is provided on when to use this tool versus siblings like get_stock_quotes, get_stock_latest_trade, or get_option_latest_quote. There are no examples, prerequisites, or exclusions.

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