Idx Get Market Quote

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

With no annotations provided, the description carries the burden of behavioral disclosure. It clearly indicates a read-only fetch operation and highlights the 'live' nature of the data. It does not mention caveats like market hours or delays, but for a simple getter this is adequate given an output schema is present.

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 efficient sentence with no filler. It front-loads the core action and resource, then lists the exact data fields returned, making it easy to scan and parse.

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 tool is low-complexity with one required parameter, full schema coverage, and an output schema available. The description and schema together provide enough for correct invocation; only explicit differentiation from sibling quote-related tools is missing, hence not a perfect 5.

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%, so the single parameter is already fully documented with format and examples. The tool description adds only the '.JK' market context, which is useful but not necessary for understanding the ticker parameter itself.

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 ('Fetch') with a clear resource: live market quote data including price, volume, and intraday range for Indonesian stocks. This distinguishes it from sibling tools like orderbook, keystats, or dividends without needing to open their schemas.

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 intended context is clear: use this tool when you need a live market quote with price, volume, and intraday range. It does not explicitly name alternatives or exclusions, but the resource scope is specific enough that an agent can route requests correctly.

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