2d-bin-packing

2d-bin-packing is a skill for Claude Code from kishorkukreja/awesome-supply-chain. It costs 109 tokens per session (9,953 once invoked), scanned A, original, MIT.

A method for arranging rectangular items inside rectangular containers, sheets, or other fixed areas while leaving as little unused space as possible.

In plain words
What is it for?
Use it for sheet cutting, box loading, rectangle layouts, and other two-dimensional packing tasks. It can account for rotation, spacing, straight-through cuts, and limits on bin sizes or quantities.
Why use it?
It helps plan layouts when many differently sized pieces must fit together, reducing wasted material or the number of containers needed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

2d-bin-packing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

2D Bin Packing

You are an expert in 2D bin packing and rectangular packing optimization. Your goal is to help pack rectangular items into 2D bins or sheets while minimizing waste, number of bins used, or maximizing space utilization.

Initial Assessment

Before solving 2D bin packing problems, understand:

  1. Problem Type

    • Pack into fixed-size bins (minimize bins used)?
    • Pack into variable-size bins (minimize total area)?
    • Single large bin (maximize utilization)?
    • Cutting from sheets (minimize waste)?
  2. Item Characteristics

    • How many items to pack? (10s, 100s, 1000s)
    • Item dimensions: width x height
    • Can items be rotated? (90-degree rotation allowed?)
    • Are items all different or some identical?
    • Any item priorities or grouping requirements?
  3. Bin/Sheet Specifications

    • Bin dimensions: width x height
    • Fixed or variable bin sizes?
    • Unlimited bins or limited quantity?
    • Any margin/spacing requirements between items?
  4. Cutting Constraints

    • Guillotine cuts only? (straight cuts across entire sheet)
    • Free-form packing allowed?
    • Maximum number of cutting stages?
    • Trim loss acceptable?
  5. Optimization Objective

    • Minimize number of bins used?
    • Minimize total area/material cost?
    • Maximize utilization percentage?
    • Minimize cutting complexity?

2D Bin Packing Framework

Problem Classification

1. 2D Bin Packing Problem (2D-BPP)

  • Pack rectangles into minimum number of identical bins
  • All items must be packed
  • Items cannot overlap
  • Items typically axis-aligned

2. 2D Strip Packing Problem

  • Fixed width, minimize height
  • Single strip (bin with infinite height)
  • Minimize total height used

3. 2D Cutting Stock Problem

  • Cut items from larger sheets
  • Minimize material waste
  • Often with guillotine constraints

4. Rectangle Packing Problem

  • Pack into single large rectangle
  • Maximize number of items packed
  • Or maximize space utilization

2d-bin-packing is a skill published in the GitHub repository kishorkukreja/awesome-supply-chain (67 stars, last pushed 12d ago), licensed MIT. It adds 109 tokens to every session and 9,953 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
