What it does

Mace Ni Benchmark is an agent skill from Hello-QM/catgo-LRG. Use when the user asks to reproduce the Kreitz 2021 Ni surface benchmark, run the MACE Ni benchmark, or compare a machine-learning potential (MACE, CHGNet, M3GNet) against DFT-D3 surface-science references. Invokes the "UMA Catalysis Tutorial" preset (template key umacatalysisscreening).

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Data & Analytics, covering Machine learning. 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 reproduce the Kreitz 2021 Ni surface benchmark
  • Run the MACE Ni benchmark
  • Compare a machine-learning potential (MACE
  • M3GNet) against DFT-D3 surface-science references

Example prompts

  • “UMA Catalysis Tutorial”
  • “/mace-ni-benchmark”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Ni bulk (FCC) — fcc Ni, a ≈ 3.524 Å (Materials Project mp-23)
  2. H₂ molecule — two H atoms ~0.74 Å apart in a 20 Å box
  3. CO* on Ni(111) — NEB reactant (CO adsorbed on a 3×3 Ni(111) slab)
  4. C* + O* on Ni(111) — NEB product (C and O separately adsorbed)

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 (its code samples are json).

    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

Mace Ni Benchmark loads about 1.3k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 605 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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
Use when the user asks to reproduce the Kreitz 2021 Ni surface benchmark, run the MACE Ni benchmark, or compare a machine-learning potential (MACE, CHGNet, M3GNet) against DFT-D3 surface-science references. Invokes the "UMA Catalysis Tutorial" preset (template key `uma_catalysis_screening`).

MACE Ni Benchmark — Kreitz 2021 Reproduction

Reproduces six Ni surface DFT-D3 target quantities end-to-end with MACE-MP-0, on a single Ni bulk source, in one workflow.

When to invoke

Trigger phrases (any of):

  • "reproduce Kreitz 2021 Ni benchmark"
  • "run the MACE Ni benchmark"
  • "benchmark MACE against DFT-D3 for Ni"
  • "validate MLP on Ni surfaces"

Also invoke when the user asks to compute multiple of the six quantities below for Ni at once — one preset is cheaper than six separate workflows.

The six target quantities

#QuantitySource nodeResult key
1γ(111), γ(100), γ(110), γ(211)surface_energyper_facet[hkl].gamma_J_per_m2
2Wulff facet area fractionswulff_constructionarea_fractions[hkl]
3H adsorption energy on Ni(111) FCC hollow (ZPE-corrected)adsorption_energyE_ads_ZPE_eV
4Coverage slope ∂E_ads/∂θ (1,2,4,8,16 H on 4×4 Ni(111))coverage_analysisfit.slope
5CO* ↔ C* + O* NEB barrierts_search (mlp_neb)activation_barrier_kcal_mol
6TS imaginary-mode frequencyfreq (mlp_vibrations)dominant_imag_freq_cm (with is_valid_ts flag)

All six are viewable side-by-side in the project dashboard's "Benchmark" tab once any workflow derived from uma_catalysis_screening (or with a matching name) is present in the project.

How to invoke

In the Workflow Editor, click New from preset → Surface Catalysis → UMA Catalysis Tutorial. A 26-node DAG loads. The template is defined in src/lib/workflow/graph-model.ts::uma_catalysis_screening.

After it loads, the user must load structures into 4 input nodes:

  1. Ni bulk (FCC) — fcc Ni, a ≈ 3.524 Å (Materials Project mp-23)
  2. H₂ molecule — two H atoms ~0.74 Å apart in a 20 Å box
  3. CO* on Ni(111) — NEB reactant (CO adsorbed on a 3×3 Ni(111) slab)
  4. C* + O* on Ni(111) — NEB product (C and O separately adsorbed)

Rebuilding the 26-node DAG by hand costs ~2x the effort and always drifts from the defaults tested against MACE-MP-0 medium. Only do this if the user needs a custom variant (e.g. different slab supercell, or a non-cubic/non-Ni system).

Expected deviations (MACE-MP-0 vs RPBE-D3)

QuantityTypical |CatGo − Kreitz|Notes
γ(hkl)~0.1 J/m²γ(111) tends to be ~0.05 J/m² higher
Wulff fractions< 0.05Dominant (111) facet rank is preserved
E_ads(H, ZPE)~0.1 eVMACE-MP-0 slightly overbinds H
Coverage slope~0.03 eV/MLSign (repulsive) should match
NEB barrier~0.2 eVLargest single deviation
ν_imag~50 cm⁻¹Sign must be negative (imaginary)

If deviations are much larger than these ranges, check:

  • Did the bulk opt converge? (fmax < 0.05 eV/Å with relax_cell: true)
  • Did NEB converge to the expected CI image? (neb_converged: true)
  • Is is_valid_ts: true on the freq step at the TS? (Exactly one imaginary mode above the 20 cm⁻¹ trivial-mode filter.)

Defaults worth preserving

  • software: mlp, model: MACE, device: auto → uses MACE-MP-0 medium via the default mace_mp("medium", default_dtype="float64") path. Checkpoint auto-downloads to ~/.cache/mace/ on first run (~200 MB, ~2 min).
  • Vibrations freeze the Ni slab and vibrate the adsorbate only (freeze_mode: layers, freeze_layers: 2, freeze_invert: false) → ~20× cheaper freqs without losing ZPE accuracy. Note: freeze_invert inverts the set of atoms ASE displaces, so false here means the frozen set (bottom 2 Ni layers) is actually frozen and everything else vibrates — the standard catalysis setup. true would vibrate only the bottom 2 Ni layers (wrong for ZPE).
  • NEB: 8 images, climb: true, FIRE optimizer, fmax: 0.05 eV/Å.
  • Coverage sweep: 1,2,4,8,16 H on 4×4 hollow-site filling.

Reproducibility

Every MLP-dispatched step writes metadata.json (captured via the C1 footer in server/workflow/engines/mlp.py) into result_json.metadata:

json
{
  "mace_torch_version": "0.3.15",
  "torch_version": "2.10.0",
  "mace_model": "mace-mp-0-medium",
  "model_sha256": null,
  "device": "cuda:0" | "cpu",
  "gpu_name": "...",
  "wall_time_s": 12.3,
  "host": "...",
  "timestamp": "..."
}

The Benchmark tab surfaces the latest MLP step's metadata panel. Users export CSV from the same tab to share the full 6-row table with the metadata footer included as RFC-4180-escaped comment lines.

  • structure/slab/ — slab generation internals
  • adsorption/ — the general E_ads formula this preset specializes
  • oer/, her/ — if the user wants surface reactivity trends on top of γ(hkl)
