Skill: capacity-constrained-transport-coordination

[Case 2]

• Initial Environment: A depot contains three crates in different storage zones and two movable hoists. Each hoist can lift one crate at a time, crates must be dropped legally, and a hoist cannot unload a crate at the exact position it currently occupies if the placement configuration is invalid.
• Real Question: Relocate the crates into the depot staging area using the available hoists and legal drop operations.
• Real Trajectory: Move Hoist-1 to Zone-A, lift Crate-1, reposition to the depot lane, and drop it. Move Hoist-2 to Zone-B, lift Crate-2, reposition and drop it. Reposition one hoist to Zone-C for the last crate while keeping placements legal.
• Real Answer: A correct plan sequences hoist travel and crate transfers so that no hoist exceeds capacity and every unload occurs at a valid destination position.
• Why this demonstrates the capability: This case tests transport coordination because the planner must interleave carrier movement with object movement under explicit capacity limits. It also checks that the agent respects action applicability constraints on unloading rather than treating transport as a simple teleportation problem. The difficulty comes from coupling who carries with where and when they may legally release.

Pipeline Execution Instructions

To synthesize data for this capability, you must strictly follow a 3-phase pipeline. Do not hallucinate steps. Read the corresponding reference file for each phase sequentially:

1. Phase 1: Environment Exploration Read the exploration guidelines to discover raw knowledge seeds: references/EXPLORATION.md

2. Phase 2: Trajectory Selection Once Phase 1 is complete, read the selection criteria to evaluate the trajectory: references/SELECTION.md

3. Phase 3: Data Synthesis Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data: references/SYNTHESIS.md
