get_latest_metrics

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

No annotations are provided, so the description carries the full burden. It explains that the tool returns the most recent snapshot across categories, but it does not disclose details such as the return structure, potential latency, or whether any fields might be missing. While the purpose is clear, richer behavioral context is absent.

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 two sentences, front-loaded with the core purpose and followed by a usage tip. Every word earns its place without redundancy, exemplifying conciseness.

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 tool with no output schema, the description covers the essential aspects: what it delivers (latest snapshot), scope (all categories), and typical use case (quick overview). It lacks some detail on the exact return format, but the simplicity of the tool makes the description sufficiently complete.

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 tool has zero parameters, so the baseline for this dimension is 4. The description adds useful context by explicitly stating that no date ranges are needed, which clarifies the parameter-less operation and distinguishes it from other metric tools that require date filters.

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 the tool's function: retrieving the most recent snapshot across all metric categories (price, supply, valuation, profit) in a single call. This specific verb+resource+scope distinguishes it from sibling tools like get_prices or get_holder_supply, which focus on individual categories.

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 clear context for when to use the tool: for a quick market overview without date ranges. It does not explicitly name alternatives or exclusions, but the emphasis on 'all metric categories' and 'single call' implies the tool is ideal over more specific getters, making it 4 rather than 5.

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