What it does
Phonopy is an agent skill from JCLiuGroup/AI-Computational-Chemist. Finite-displacement phonon workflows with phonopy. Use for displacement generation, force collection from VASP or MLP backends, force constants, phonon band structure and DOS, thermal properties, and imaginary-mode diagnosis.
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `examples/README.md`, `references/errors.md` and `references/resources.md`).
When your agent uses it
- Displacement generation
- Force collection from VASP
- Force constants
- Phonon band structure and DOS
Example prompts
- “/phonopy”
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
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
Phonopy loads about 351 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 131 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 131 words (~351 tokens).
“Pipeline: tightly relaxed structure → displacements → one static force run each (identical settings) → FORCE_SETS → band/DOS/thermal analysis.”

Questions about Phonopy
What does Phonopy do?
Finite-displacement phonon workflows with phonopy. An agent skill from JCLiuGroup/AI-Computational-Chemist. Phonopy is an agent skill from JCLiuGroup/AI-Computational-Chemist. Finite-displacement phonon workflows with phonopy.
When should I use Phonopy?
Phonopy fits situations like: displacement generation; force collection from VASP; force constants; phonon band structure and DOS.
How do I install Phonopy in Claude Code?
Run `npx skills add JCLiuGroup/AI-Computational-Chemist --skill phonopy -a claude-code`. Or copy the skill folder (tools/phonopy in JCLiuGroup/AI-Computational-Chemist) into .claude/skills/phonopy in your project. Claude Code loads it when a task matches its description.
How do I install Phonopy in Codex?
Run `npx skills add JCLiuGroup/AI-Computational-Chemist --skill phonopy -a codex`. Or copy the skill folder (tools/phonopy in JCLiuGroup/AI-Computational-Chemist) into .agents/skills/phonopy in your project. Codex loads it when a task matches its description.
Can I use Phonopy 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 phonopy -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/phonopy, .gemini/skills/phonopy, .github/skills/phonopy and .opencode/skills/phonopy in your project.
What does Phonopy need to run?
SKILL.md names no scripts, command-line tools or credentials: Phonopy is instructions for the agent only.
Does Phonopy access the network?
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.
Is Phonopy 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. Review the folder before installing.
What licence does Phonopy use?
Phonopy 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 Phonopy use?
About 351 tokens (SKILL.md is roughly 1.4k 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 1.4k tokens, read only when the agent opens those files.
