get_gold_price

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

With no annotations, the description carries the full burden. It discloses that the price is real-time and based on 3.75 grams, but does not describe return format, caching, or any error/rate-limit behavior. This is minimal for a tool with no annotation context.

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 one short sentence that immediately states the tool's core function and the unit. Every word earns its place; no fluff.

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 zero-parameter read tool, the description is adequate but leaves gaps: no return format, no mention of the currency (likely KRW but unstated), and no guidance on how this relates to other tools. The lack of output schema makes this slightly under-specified.

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?

No parameters exist, so baseline is 4. The description adds useful context about the measurement basis (3.75g), which helps the agent interpret the output even though no parameters are involved.

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 a specific verb '가져옵니다' (retrieve) and a specific resource '실시간 금 시세' (real-time gold price), with a clarifying unit (3.75g). This distinguishes it from sibling tools like get_exchange_rate and get_bitcoin_price.

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 mention of when to use this tool versus alternatives like get_all_prices. The description provides no exclusions or preferences, so the agent must infer usage solely from the name and description.

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