get_hip3_freshness

Read-onlyIdempotent

Check data freshness for a HIP-3 coin across orderbook, trades, funding, and open interest. Shows when each data type was last updated and current lag.

Instructions

Get data freshness for a HIP-3 coin across all data types (orderbook, trades, funding, OI). Symbols are CASE-SENSITIVE (e.g. 'km:US500'). Shows when each data type was last updated and current lag.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds useful behavioral detail: 'Shows when each data type was last updated and current lag,' which informs the agent about the output content beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences, no redundancy, and front-loaded with the core action. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one required parameter, read-only, output schema exists), the description covers the purpose, output content, and usage hints. No gaps remain for an agent to misinterpret.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage for the single parameter 'coin', including examples and case sensitivity. The description does not add additional meaning beyond what the schema provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the purpose: 'Get data freshness for a HIP-3 coin across all data types (orderbook, trades, funding, OI).' It specifies the verb, resource, and scope, distinguishing it from siblings like get_freshness or get_hip4_freshness.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides usage guidance by noting case-sensitive symbols and suggesting get_hip3_instruments to list all symbols. It does not explicitly state when not to use, but the HIP-3 specificity and examples offer clear context.

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