SKILL.md

The same SKILL.md was published earlier as nssmd/roborsi/grab-roller.

grab_roller (atomic)

RoboTwin sapien task. Single-arm.

Goal

Pick up the paint roller from the table and lift it clear (visible daylight between roller and tabletop).

Success

The roller is visibly lifted clear of the table and remains held. The harness records the simulator's final verdict after execution.

v0.4.0 changes (from failure run 20260525-074806-d1ab32)

  • Added forbidden_tools: [grasp_handle_pca] to frontmatter — runner

should block / penalize this call (VLM ignored the v0.3 prose ban).

  • Tightened prompt into a numbered MANDATORY TOOL ORDER instead of

scattered "PREFER / ACCEPTABLE FALLBACK" wording.

  • Made the pre-done gate explicit: both verify tools must appear in the

IMMEDIATELY preceding 2 tool calls.
