gold_market_snapshot

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

No annotations are provided, and the description does not disclose behavioral traits such as whether it is read-only, what return format is expected, or any side effects. The phrase 'structured snapshot' implies a read operation but is not explicit, and nothing about permissions or rate limits is mentioned.

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 with no wasted words, but it is under-specified. It does not provide enough detail for an agent to understand the tool's full behavior, so it is not concise in the sense of earning its place.

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, no annotations, and no output schema, the description carries the full burden of explaining what the snapshot includes and how to use it. It fails to describe the return structure or the effect of the timeframe parameter, making it insufficient for reliable tool selection and invocation.

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 has a single 'timeframe' parameter with a default of '1h' but no description. Since schema coverage is 0%, the description should explain the parameter, but it does not mention timeframe at all, leaving the agent without guidance on valid values or how it affects the snapshot.

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 says 'One-call structured snapshot of gold's current market state,' but it does not specify what data the snapshot contains (price, OHLC, correlations, etc.). It provides a general sense of 'market state' but lacks specificity to fully distinguish it from sibling tools like get_gold_price or get_gold_ohlcv.

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 sibling tools. There is no mention of scenarios where this snapshot is preferred, nor any exclusions or alternatives.

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