heterostructureA skill your agent uses when the user asks to build a heterostructure, interface, van der Waals stack, substrate-film system, or lattice-matched bilayer from two different materials.
Heterostructure is an agent skill from Hello-QM/catgo-LRG. Use when the user asks to build a heterostructure, interface, van der Waals stack, substrate-film system, or lattice-matched bilayer from two different materials.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: AI-driven workbench for computational materials science — interactive 3D structure viewer, natural-language CatBot assistant, visual DAG workflow engine, HPC job submission… The licence is AGPL-3.0.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit fd6291b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Heterostructure loads about 1.7k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 506 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/heterostructure/SKILL.md (or your agent's skills folder).A heterostructure is a layered stack of two different materials joined at an interface. The Zur-McGill (ZSL) algorithm finds superlattice matches that minimize lattice mismatch between substrate and film.

}}| Mismatch Level | Tolerance Values | Use Case |
|---|---|---|
| Tight | 0.03 | Epitaxial growth, accurate interfaces |
| Standard | 0.09 | General screening, most applications |
| Loose | 0.15 | Exploratory, when few matches found |
Tighter tolerances produce fewer but higher-quality matches. Loosen
tolerances if no matches are found, or increase max_area.
max_area values (> 500 A^2) can produce structures with
thousands of atoms. Start small and increase if needed.gap parameter controls the initial interface distance before
relaxation. Too small (< 1.5 A) causes atomic overlap; too large
(> 4 A) may not capture interface bonding.© Hello-QM, AGPL-3.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Run `npx skills add Hello-QM/catgo-LRG --skill heterostructure -a claude-code`. Or copy the skill folder (.claude/skills/structure-heterostructure in Hello-QM/catgo-LRG) into .claude/skills/heterostructure in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Hello-QM/catgo-LRG --skill heterostructure -a codex`. Or copy the skill folder (.claude/skills/structure-heterostructure in Hello-QM/catgo-LRG) into .agents/skills/heterostructure in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Hello-QM/catgo-LRG --skill heterostructure -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/heterostructure, .gemini/skills/heterostructure, .github/skills/heterostructure and .opencode/skills/heterostructure in your project.
SKILL.md names no scripts, command-line tools or credentials: Heterostructure is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Heterostructure is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
