What it does

Catgo Workflow is an agent skill from Hello-QM/catgo-LRG. Create and manage computational chemistry workflows with CatGo. Supports VASP, CP2K, ORCA, MLP, LAMMPS. Build OER/HER/CO2RR workflows, geometry optimization, frequency analysis, Gibbs energy calculations.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 40 other files (for example `__init__.py`, `builtins.py` and `builtins_impl.py`).

It sits in Research & Science. 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

  • Research & Science work in your project

Example prompts

  • “/catgo-workflow”

Requirements

  • Python 3

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

    Ships script files (Python, from the files we listed), which the agent can run.

    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

Catgo Workflow loads about 960 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~960

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.

description
Create and manage computational chemistry workflows with CatGo. Supports VASP, CP2K, ORCA, MLP, LAMMPS. Build OER/HER/CO2RR workflows, geometry optimization, frequency analysis, Gibbs energy calculations.

CatGo Workflow Skill

Quick Start — Python API

python
from catgo.workflow import Workflow
from catgo.workflow.builtins import geo_opt, freq, gibbs_energy

wf = Workflow("RuO2 OER")

# Input structure
slab = wf.add_task("structure_input", structure=structure_json)

# Geometry optimization → Frequency → Gibbs Energy
opt = wf.add_task(geo_opt, structure=slab.output.structure, ENCUT=520, system_name="*OH")
frq = wf.add_task(freq, structure=opt.output.structure, system_name="*OH",
                   freeze_mode="layers", freeze_layers=4)
gib = wf.add_task(gibbs_energy, energy=opt.output.energy,
                   frequencies=frq.output.frequencies, system_name="*OH")

wf.submit()  # Engine picks it up automatically

HPC Confirmation Gate: By default, HPC tasks pause at PENDING_REVIEW after local preprocessing completes, so users can verify structures and parameters before spending HPC resources. Users confirm via the frontend "Confirm & Submit" button (per-task or "Confirm All"). To skip this gate, call wf.submit(auto_submit=True).

HPC Confirmation Required: Before calling wf.submit() or catgo_workflow_engine(action="submit"), you MUST ask the user which HPC cluster to use and confirm job parameters (partition, account, walltime, ntasks). These can be set per-task via add_task params. Never submit without user confirmation.

Available Task Types

HPC Calculations
  • geo_opt — Geometry optimization (VASP/CP2K/ORCA/MLP)
  • single_point — Single point energy (VASP/CP2K/ORCA)
  • freq — Vibrational frequencies (VASP/CP2K/ORCA)
  • cell_opt — Cell optimization (VASP/CP2K)
  • md — Molecular dynamics (VASP/CP2K/LAMMPS/MLP)
  • ts_search — Transition state search (Sella/ORCA NEB-TS)
Local Analysis
  • gibbs_energy — G = E_DFT + ZPE - TS
  • free_energy_diagram — Plot reaction energy diagram
  • dos_analysis — Density of states analysis
  • charge_analysis — Bader charge analysis
Structure Building
  • structure_input — Provide input structure
  • slab_gen — Generate surface slab
  • adsorbate_place — Place adsorbate on surface

Key Parameters

VASP
  • software="vasp", ENCUT, EDIFF, EDIFFG, NSW, ISIF, IBRION
  • ISMEAR, SIGMA, ISPIN, NCORE, KPAR
Frequency
  • freeze_mode: "none", "layers", "z_range", "element", "indices", "manual"
  • freeze_layers: number of bottom layers to freeze
  • freeze_z_below: freeze atoms below this z coordinate (Angstrom)
Gibbs Energy
  • phase: "adsorbed" (harmonic) or "gas" (ideal gas)
  • temperature: K (default 298.15)
  • freq_cutoff: cm-1 (default 50, for adsorbed phase)

Output References

Connect tasks by passing .output.key:

python
opt.output.structure   # optimized structure
opt.output.energy      # DFT energy (eV)
frq.output.frequencies # vibrational frequencies
frq.output.zpe         # zero-point energy
gib.output.gibbs       # Gibbs free energy

Workflow Patterns

OER Overpotential
python
for ads in ["OH", "O", "OOH"]:
    opt = wf.add_task(geo_opt, structure=slab.output.structure,
                      system_name=f"*{ads}")
    frq = wf.add_task(freq, structure=opt.output.structure,
                      freeze_mode="layers", freeze_layers=4)
    gib = wf.add_task(gibbs_energy, energy=opt.output.energy,
                      frequencies=frq.output.frequencies, phase="adsorbed")
Convergence Test
python
for encut in [400, 500, 600, 700]:
    wf.add_task(single_point, structure=struct.output.structure,
                ENCUT=encut, system_name=f"ENCUT={encut}")
