Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/bbeierle12/skill-mcp-claude --skill structural-physics- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads structural-physics automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Structural Physics
Stability validation and damage systems for building mechanics.
Quick Start
import { HeuristicValidator } from './scripts/heuristic-validator.js';
import { DamageSystem } from './scripts/damage-propagation.js';
// Rust/Valheim style stability
const validator = new HeuristicValidator({ mode: 'heuristic' });
validator.addPiece(piece);
const result = validator.validatePlacement(newPiece);
// result: { valid: true, stability: 0.85, supports: [...] }
// Damage and collapse
const damage = new DamageSystem(validator);
damage.applyDamage(piece, 50, 'physical');
damage.applyExplosiveDamage(position, 100, 10); // radius damage
Reference
See references/structural-physics-advanced.md for:
- Physics mode comparison (arcade vs heuristic vs realistic)
- Material properties and decay rates
- Damage state thresholds
- Cascade mechanics
Scripts
scripts/heuristic-validator.js- Fast validation (Fortnite/Rust/Valheim modes)scripts/stability-optimizer.js- Caching and batch updates for large structuresscripts/damage-propagation.js- Damage states, fire spread, cascading collapsescripts/physics-engine-lite.js- Optional realistic stress/strain simulation
Physics Modes
- Arcade (Fortnite): Connectivity only, instant collapse, best for combat
- Heuristic (Rust/Valheim): Stability %, predictable rules, best for survival
- Realistic: Full stress/strain, computationally expensive, best for engineering sims
FAQ
What does the structural-physics skill do?
Structural validation and damage systems for Three.js building games. Use when implementing building stability (Fortnite/Rust/Valheim style), damage propagation, cascading collapse, or realistic physics simulation. Supports arcade, heuristic, and realistic physics modes.
How do I install structural-physics?
Run npx skills add https://github.com/bbeierle12/skill-mcp-claude --skill structural-physics in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/structural-physics/ (personal) or .claude/skills/structural-physics/ (project).
Which AI agents can use structural-physics?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is structural-physics safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains structural-physics?

paper-context-resolver
lllllllama/rigorpilot-skills
Rigor Paper Context helper for README-first deep learning repo reproduction. Use only when the README and repository files leave a narrow reproduction-critical gap and the task is to resolve a specific paper detail such as dataset split, preprocessing, evaluation protocol, checkpoint mapping, or runtime assumption from primary paper sources while recording conflicts. Do not use for general paper summary, repo scanning, environment setup, command execution, title-only paper lookup, or replacing README guidance by default.
caveman-learn
juliusbrussee/caveman
Act on a Caveman learn report - review the ranked token sinks, apply cost-lowering fixes with per-edit consent, and report what those fixes returned. Use when asked to lower an agent's token cost, what caveman has saved, to trim a heavy CLAUDE.md, or to offload re-pasted context into cavemem.
