modeling

modeling is a skill for Claude Code from MonumentalSystems/Atlas-Agent-Teams. It costs 13 tokens per session (1,556 once invoked), scanned A, original, MIT.

Guidance for creating three-dimensional models from geometry, curves, photos, or digital sculpting. It explains concepts such as vertices, faces, normals, and topology—the structure and flow of a model’s surfaces.

In plain words
What is it for?
Planning and building 3D objects, selecting modeling workflows, and applying good geometry practices.
Why use it?
It provides a reference for choosing suitable modeling methods and keeping models well-shaped and usable. It also distinguishes hard-surface objects, such as vehicles and buildings, from organic forms, such as characters.

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

modeling 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 9d 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.

3D Modeling

3D Modeling Fundamentals

Geometry Basics

  • Vertices: Points in 3D space (x, y, z coordinates)
  • Edges: Lines connecting vertices
  • Faces: Surfaces formed by edges (triangles, quads, n-gons)
  • Normals: Direction a face is pointing
  • Topology: Arrangement and flow of geometry

Modeling Workflows

  • Box Modeling: Starting with primitives and refining
  • Sculpting: Digital sculpting for organic forms
  • NURBS Modeling: Mathematical curves and surfaces
  • Procedural Modeling: Algorithmic generation of geometry
  • Photogrammetry: Creating models from photos

Coordinate Systems

  • World Space: Global coordinate system
  • Local Space: Object's own coordinate system
  • View Space: Camera-relative coordinates
  • Screen Space: 2D screen coordinates

Hard Surface vs Organic Modeling

Hard Surface Modeling

  • Characteristics: Man-made objects, sharp edges, precise shapes
  • Techniques: Boolean operations, bevels, chamfers, inset
  • Tools: Edge loops, bevel modifier, boolean modifier
  • Applications: Vehicles, weapons, architecture, props
  • Best Practices: Maintain quads, avoid n-gons, use supporting edges

Organic Modeling

  • Characteristics: Natural forms, flowing shapes, soft edges
  • Techniques: Sculpting, retopology, edge flow following anatomy
  • Tools: Sculpt brushes, dynamesh, remesh, smooth
  • Applications: Characters, creatures, plants, organic environments
  • Best Practices: Follow anatomical structure, maintain edge flow for deformation

Subdivision Modeling Techniques

Subdivision Surfaces

  • Catmull-Clark: Standard subdivision algorithm
  • Loop Subdivision: Alternative subdivision method
  • Smooth Shading: Smooths surface normals
  • Creases: Sharp edges on subdivision surfaces
  • Edge Weighting: Control subdivision strength per edge

Edge Flow

  • Edge Loops: Continuous rings of edges
  • Supporting Edges: Edges that define shape and prevent pinching
  • Poles: Vertices with 3, 5, or more edges
  • Pole Placement: Strategic placement for deformation
  • Topology Flow: Following natural forms and deformation paths

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

modeling is a skill published in the GitHub repository MonumentalSystems/Atlas-Agent-Teams (21 stars, last pushed 28d ago), licensed MIT. It adds 13 tokens to every session and 1,556 once invoked, about $0.0001 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.
