What its author says it does
Copied from the file, not written here
Use this skill to run a deterministic Psi4 single-point Hartree-Fock energy on a tiny water molecule. Do not use it for production quantum chemistry benchmarking or large basis-set studies.

Purpose
Provide a minimal, runnable Psi4 starter that computes one deterministic single-point energy for a bundled water geometry and records the result as compact JSON.
When to use
- You need a verified local Psi4 entry point.
- You want a tiny quantum-chemistry smoke calculation before scaling to larger molecules or better methods.
- You need a deterministic summary that can be tested in CI-like local workflows.
When not to use
- You need high-accuracy energetics, conformer searches, or production optimizations.
- You need solvent models, post-HF methods, or large basis sets.
Inputs
- Optional output JSON path
- Optional method and basis, defaulting to
hfandsto-3g
Outputs
- JSON summary with Psi4 version, job label, molecule metadata, and single-point energy in Hartree
Requirements
slurm/envs/psi4with Psi4 installed
Procedure
- Run
slurm/envs/psi4/bin/python skills/computational-chemistry-and-molecular-simulation/psi4-single-point-energy/scripts/run_psi4_single_point.py --out skills/computational-chemistry-and-molecular-simulation/psi4-single-point-energy/assets/water_hf_sto3g_summary.json. - Confirm the output reports
psi4_version,method,basis, and a negativeenergy_hartree. - Reuse the script as a seed for larger Psi4 workflows after validating the dedicated prefix.
Validation
- The command exits successfully under
slurm/envs/psi4/bin/python. - The result reports a 3-atom water molecule.
- The
hf/sto-3genergy is reproducible for the bundled geometry.
Failure modes and fixes
- Missing Psi4 prefix: install or reactivate
slurm/envs/psi4. - Import failure: confirm the script is run with
slurm/envs/psi4/bin/python, not the base interpreter. - Numerical drift after edits: reset the geometry, method, basis, and thread count to the bundled defaults.
Safety and limits
- Educational starter only.
- The bundled water calculation is intentionally tiny and not suitable for scientific claims by itself.
