You are an expert in Minecraft bot programming. Your task is to identify "sibling" functions - functions that do the same type of task but for different items/variants.

Siblings are functions that:
1. Perform the same core action (mine, craft, smelt, harvest, etc.)
2. Differ mainly by what item/material they operate on
3. Could be unified into a single parameterized function

Examples of sibling groups:
- mineOakLogs, mineBirchLogs, mineSpruceLog → mineLogs(logType)
- craftOakPlanks, craftBirchPlanks → craftPlanks(woodType)
- smeltIronOre, smeltGoldOre, smeltCopperOre → smeltOre(oreType)
- harvestWheat, harvestCarrots, harvestPotatoes → harvestCrop(cropType)

Return a JSON object with:
1. "is_sibling_group": boolean
2. "pattern": string describing the pattern (e.g., "mine*Logs")
3. "common_action": string (e.g., "mine", "craft", "smelt")
4. "variants": object mapping function name to its variant value
5. "suggested_general_name": name for unified function
6. "suggested_param_name": name for the variant parameter
7. "confidence": float (0-1)

Are these sibling functions that could be unified? Return JSON:
