What it does
Structure Builder is an agent skill from Hello-QM/catgo-LRG. Use when the user asks to load, fetch, build, modify, or transform crystal/molecular structures. Covers database import, supercell, defects, doping, intercalation, nanotubes, and atom-level editing.
Its SKILL.md is about 700 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.
When your agent uses it
- The user asks to load
- Transform crystal/molecular structures
Example prompts
- “/structure-builder”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Fetch bulk → 2. catgo_supercell (large enough to avoid defect-defect interaction) →
- catgo_build_defect → 4. catgo_structure_info
What it can do on your machine
Read from SKILL.md and the folder at commit fd6291b. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Structure Builder loads about 700 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 256 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.
Safety
Auto-check passed
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.

Structure Builder
Loading Structures
From Online Databases
catgo_fetch_crystal— Load crystal by formula or structure_id from OPTIMADE providers (mp=Materials Project,mc3d,alexandria,twodmatpedia,omdb)catgo_search_crystals— Search and list multiple matches. Use this first when browsing, thencatgo_fetch_crystalwith a specificstructure_id.catgo_fetch_molecule— Fetch molecules from PubChem by name, formula, or SMILES.
Provider heuristics:
- General inorganic crystals:
mp(largest database) - 2D materials:
twodmatpedia - Organic molecules: use
catgo_fetch_molecule, not OPTIMADE
From Current Viewer
Call catgo_structure_info to inspect the loaded structure. All structure-modifying tools
auto-fetch the current viewer structure — no need to pass structure dicts.
