What it does
Gaussian is an agent skill from JCLiuGroup/AI-Computational-Chemist. Prepare, validate, and troubleshoot Gaussian molecular quantum chemistry jobs. Use for single-point, geometry optimization, frequency/thermochemistry, transition states, IRC, scans, solvation, weak interactions, TD-DFT spectra, wavefunction stability, and Gaussian input/output handling for finite molecules.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including scripts and reference files (for example `examples/README.md`, `references/basis-ecp-genecp.md` and `references/energy-thermochemistry.md`).
It sits in Research & Science, covering Drug discovery and cheminformatics.
When your agent uses it
- Geometry optimization
- Frequency/thermochemistry
- Transition states
- Weak interactions
Example prompts
- “/gaussian”
Requirements
- Python 3
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Decide the scientific quantity before choosing Gaussian keywords; consult knowledge/molecular-qc-practical-rules.md when the issue is…
- Build the route from running.md plus the relevant topic reference. State charge/multiplicity origin.
- Submit via hpc-submit (single-node unless a site-specific Linda setup is explicitly approved).
- Validate: uv run scripts/parse_gaussian.py JOB.log; rules in validation.md. On error → exact link/message in errors.md, then the topic…
- Extract energies and properties only after validation, using energy-thermochemistry.md or properties-utilities.md.
- For post-processing beyond Gaussian's own output, hand off validated .log/.fchk/cube files to tools/multiwfn/.
What it can do on your machine
Read from SKILL.md and the folder at commit e27b555. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Gaussian loads about 1k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 393 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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 393 words (~1,024 tokens).
“Job types: SP, Opt, Freq, Opt+Freq, TS search, IRC, scans, solvent models, counterpoise, wavefunction stability, and TD-DFT spectra — route templates and operational details are in the references below.”

Questions about Gaussian
What does Gaussian do?
Prepare, validate, and troubleshoot Gaussian molecular quantum chemistry jobs. Gaussian is an agent skill from JCLiuGroup/AI-Computational-Chemist. Prepare, validate, and troubleshoot Gaussian molecular quantum chemistry jobs.
When should I use Gaussian?
Gaussian fits situations like: geometry optimization; frequency/thermochemistry; transition states; weak interactions.
How do I install Gaussian in Claude Code?
Run `npx skills add JCLiuGroup/AI-Computational-Chemist --skill gaussian -a claude-code`. Or copy the skill folder (tools/gaussian in JCLiuGroup/AI-Computational-Chemist) into .claude/skills/gaussian in your project. Claude Code loads it when a task matches its description.
How do I install Gaussian in Codex?
Run `npx skills add JCLiuGroup/AI-Computational-Chemist --skill gaussian -a codex`. Or copy the skill folder (tools/gaussian in JCLiuGroup/AI-Computational-Chemist) into .agents/skills/gaussian in your project. Codex loads it when a task matches its description.
Can I use Gaussian in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add JCLiuGroup/AI-Computational-Chemist --skill gaussian -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gaussian, .gemini/skills/gaussian, .github/skills/gaussian and .opencode/skills/gaussian in your project.
What does Gaussian need to run?
Going by SKILL.md and its folder, Gaussian needs Python for the scripts in its folder and the command-line tools its instructions call (uv). Our summary lists: Python 3.
Does Gaussian access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Gaussian safe to install?
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Gaussian use?
Gaussian has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Gaussian use?
About 1k tokens (SKILL.md is roughly 4.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.1k tokens, read only when the agent opens those files.
What are the alternatives to Gaussian?
Skills that share tags, products or a category with Gaussian: Molecode (AtomFlow-AI/MoleCode, 305 stars), Drug Discovery (Tommy-yw/RunbookHermes, 546 stars), DiffDock Molecular Docking (K-Dense-AI/scientific-agent-skills, 48k stars) and Biomedical Analysis Dispatch (xjtulyc/MedgeClaw, 617 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Gaussian?
JCLiuGroup (a GitHub organization) maintains it in JCLiuGroup/AI-Computational-Chemist, which has 143 GitHub stars. The repository holds 21 skills in this directory. The repository was last updated on September 27, 2026.
