Mc Place Until Supported

Minecraft Place Until Supported Tool

Creates reliable footing by placing blocks until observed support becomes provably solid. Absorbs placement uncertainty and never exposes 'accepted but ineffective' outcomes.

Purpose

Reliable footing creation for safe movement and construction. Uses observation-verification loop to ensure blocks are actually placed and provide support, handling asynchronous placement uncertainty.

Input

• value: Item/block name (preferred, optional - auto-selects from inventory if not provided)
• item: Item/block name (alternative to value, optional)
• placement_policy: One of {"underfoot", "forward-underfoot", "lateral"} (default: "underfoot")
• max_attempts: Integer maximum placement attempts (default: 3)
• verify_delay: Float seconds to wait before re-observation (default: 0.0)

Output

Returns uniform_return format with:

• value: Text summary with outcome and attempt count
• data: Structured data dict (machine-readable). Key fields:
  • outcome: "SUPPORTED" | "NO_PLACEABLE_TARGET" | "PLACEMENT_IMPOSSIBLE" | "INVENTORY_EXHAUSTED" | "SUPPORT_AMBIGUOUS"
  • attempts_made: Integer
  • max_attempts: Integer
  • placement_policy: String
  • item: String

Behavior & Performance

• Observation-verification loop: Places block, observes, verifies support
• Retries up to max_attempts if support not achieved
• Handles asynchronous placement uncertainty
• Auto-selects item from inventory if not specified

Guidelines

• Use for creating reliable footing before movement
• SUPPORTED outcome indicates solid footing achieved
• NO_PLACEABLE_TARGET indicates no valid placement location
• INVENTORY_EXHAUSTED indicates no more blocks available
• SUPPORT_AMBIGUOUS indicates uncertain support state - may need retry

Usage Examples

Place until supported with defaults:

{"type":"mc-place-until-supported","value":"dirt","placement_policy":"underfoot","max_attempts":3,"out":"$place"}

Place forward-underfoot:

{"type":"mc-place-until-supported","item":"cobblestone","placement_policy":"forward-underfoot","out":"$place"}
