What it does
Chem Solution Md is an agent skill from learningmatter-mit/AtomisticSkills. Set up and run molecular dynamics simulations of molecules in explicit solvent boxes using Packmol for box construction and MLIPs for dynamics.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files, including scripts (for example `examples/Li_EC_MACE-MH-1/README.md`, `examples/Li_EC_MACE-MH-1/box_metadata.json` and `examples/Li_EC_MACE-MH-1/solution_analysis.json`).
It sits in Research & Science, covering Physical and earth sciences and Drug discovery and cheminformatics. It works with Model Context Protocol. The repository describes itself as: Integrating AtomisticSkills into Agentic IDEs (Cursor, Claude Code, Codex, Google Antigravity, Hermes Agent, etc). The licence is MIT.

Workflow steps
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 7f2d86d. 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 2 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
doi.org

github.com
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
Chem Solution Md loads about 1.9k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 615 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it
~40
When it runs· the whole SKILL.md, loaded when a task matches
~1.9k
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.

<!-- mcp-tools-note -->
[!NOTE]
Steps written server.tool are MCP tool calls: mace.load_model is the load_model
tool of the mace server (mcp__mace__load_model, or
mcp__plugin_atomistic-skills_mace__load_model when installed as a plugin).
Without a connected server, run the same tools from the shell. Tools named in
one command share a process, so a model loaded by load_model stays loaded:
Set up and run molecular dynamics (MD) simulations of molecules in explicit solvent. This skill covers three stages: (1) building a solvation box with Packmol, (2) running NPT/NVT MD using MLIPs, and (3) analyzing the trajectory for radial distribution functions (RDFs), coordination numbers, density convergence, and mean-square displacement (MSD).
[!IMPORTANT]
This skill bridges gas-phase chem-* skills and condensed-phase mat-* skills by providing workflows for solvation dynamics, liquid structure characterization, and dissolution studies.
1. Prerequisites
Packmol binary must be installed and on PATH for the cpu environment.
RDKit must be available in the cpu environment (for SMILES → 3D geometry).
An MLIP backend must be available via MCP tools (MACE, MatGL, or FairChem).
Organic solvents: Use MACE-MH-1 with omol head, or UMA with omol task.
Aqueous inorganic systems: Use MACE-MH-1 with omat_pbe head, or MatGL/CHGNet.
Mixed organic-inorganic: Use UMA which handles both.
3. Workflow
Step 1: Build Solvation Box
Use the box-building script to create a solvated system with Packmol:
bash
# Pure solvent box (64 water molecules)
${CLAUDE_SKILL_DIR}/../../venv/run cpu python ${CLAUDE_SKILL_DIR}/scripts/build_solvation_box.py \
--solvent water \
--num_solvent 64 \
--output_dir research/my_folder/solvation_box
# Solute in solvent (NaCl in 64 water molecules)
${CLAUDE_SKILL_DIR}/../../venv/run cpu python ${CLAUDE_SKILL_DIR}/scripts/build_solvation_box.py \
--solute_smiles "[Na+].[Cl-]" \
--solvent water \
--num_solvent 64 \
--output_dir research/my_folder/solvation_box
Key Parameters:
