## Why single_tick is rated Low

This tool retrieves market tick data without modifying, executing external operations, or creating financial obligations. Tick data is read-only market information. Despite the empty description, the name and server context clearly indicate data retrieval functionality, which is a Read operation. No side effects or destructive capabilities are indicated.

From the tool's own definition: "Tool name 'single_tick' with sibling tools named batch_ticks, single_quote, batch_quotes, single_kline, batch_klines all operating on market data retrieval."

## Use case

AI agents call single_tick to retrieve information from Itick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",

  "tools": {
    "single_tick": {}
  }
}
