What it does
Antechamber is an agent skill from jinzhezenggroup/computational-chemistry-agent-skills. A command-line tool in AmberTools for preparing small molecules or non-standard residues within GAFF/AMBER-compatible chemical space for molecular mechanics simulations, by automating atom/bond typing, charge generation or import, and force-field–compatible input generation. USE WHEN you are working in AMBER, dealing with molecules not covered by standard force fields, and already have a structure that can be processed (e.g., pdb, mol2, ac, gout). Typical use cases include parameterizing ligands or modified…
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires AmberTools installed and available in PATH
It sits in Research & Science, covering Drug discovery and cheminformatics and Physical and earth sciences. The repository describes itself as: Agent skills to run computational-chemistry tasks, used in OpenClaw. The licence is LGPL-3.0-or-later.
When your agent uses it
- You are working in AMBER

Requirements
- Compatibility (from SKILL.md): Requires AmberTools installed and available in PATH
What it can do on your machine
Read from SKILL.md and the folder at commit 5c19e75. 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 bash).
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):
ambermd.org
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.
Compatibility
Requires AmberTools installed and available in PATH
From compatibility in the SKILL.md frontmatter.
Context cost
Antechamber loads about 3.2k tokens when it runs. Until then it costs about 220 tokens; SKILL.md has 824 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.

- description
- A command-line tool in AmberTools for preparing small molecules or non-standard residues within GAFF/AMBER-compatible chemical space for molecular mechanics simulations, by automating atom/bond typing, charge generation or import, and force-field–compatible input generation. USE WHEN you are working in AMBER, dealing with molecules not covered by standard force fields, and already have a structure that can be processed (e.g., pdb, mol2, ac, gout). Typical use cases include parameterizing ligands or modified residues (assigning atom/bond types, generating or reading partial charges), converting structures from upstream tools into mol2/prepi formats, and preparing topology-ready inputs for downstream tools such as LEaP. DO NOT USE for standard residues, metal complexes, inorganic systems, or when no valid molecular structure is available (e.g., only SMILES).

NOTE:
- RESP charge method requires a Gaussian output file with ESP data (
-fi gout), a Gaussian ESP file (-fi gesp) or a GAMESS dat file (-fi gamess) as input. - CM1 and CM2 charge methods require specific interfaces and are not recommended for general use.
- ESP (Kollman) charge method requires a Gaussian output file with ESP data (
-fi gout) as input. - Gasteiger charge method will ignore the net molecular charge and assign charges based on atom types and connectivity, which may not be suitable for charged molecules.
- Read in charge method requires a charge file (
-cf CHARGE_FILE) with a whitespace-separated list of floating-point charges, ordered exactly as atoms in the input structure, with no indices, labels, or extra columns.
Parameter Selection Heuristics
Unmentioned options are recommended to be left at their default values unless you have specific needs or understand the implications of changing them. The following heuristics can help guide your choices for the most commonly used options:
Basic IO
-i,-fi,-o,-fomust appear.-a,-fa,-aoare used when you want to read in additional information from another file and overwrite specific attributes in the input file. WARNING: this can lead to mismatches if the additional file does not correspond to the input file in atom order.-rnis used when you want to specify a custom residue name in order to increase readability.
Show full SKILL.md (390 more words)Show less
Charge Generation
-cis used when the input file does not contain usable atomic charges, including cases where (1) the input file lacks charge information, (2) the existing charges cannot be directly interpreted (e.g., they originate from upstream quantum chemistry calculations where charges are not explicitly mapped one-to-one to atoms or are stored in complex formats), or (3) new charges need to be recalculated using a chosen method.- Typically,
-c bccis recommended for general use. Unless higher accuracy is required or the system is sensitive to charge details, in which case-c respwith a properly prepared Gaussian output file is recommended. The other charge methods are generally not recommended for typical use cases. -cfis only used when-c rcis specified, otherwise it will be ignored.-ncis required when charges need to be calculated and the net molecular charge is not zero. It will be ignored if there is no charge calculation.
Calculation Control
-ekis not recommended for general use. If additional mopac or sqm keywords are needed, it is recommended to run mopac or sqm separately.-gk,-gopt,-gsp,-gm,-gn,-gdsk,-gv,-geshould never be used. If a gaussian job is needed, use external Gaussian instead.
Atom Type Assignment
-atis used when the input file does not contain usable atom type information.- Typically,
-at gaff2is recommended for general use. Unless you are parameterizing a modified residue that must be fully consistent with the standard AMBER force fields, in which case-at ambershould be used to ensure compatibility and higher accuracy. The other atom type options are generally not recommended for typical use cases.
Common Examples
Convert antechamber format to Sybyl Mol2
antechamber -i input.ac -fi ac -o output.mol2 -fo mol2Convert antechamber format to Sybyl Mol2, and use charges from additional file instead
antechamber -i input.ac -fi ac -o output.mol2 -fo mol2 -a additional.mol2 -fa mol2 -ao crgConvert antechamber format to Sybyl Mol2, and use read in charges
antechamber -i input.ac -fi ac -o output.mol2 -fo mol2 -c rc -cf charges.txtConvert antechamber format to Sybyl Mol2, and assign AMBER atom types
antechamber -i input.ac -fi ac -o output.mol2 -fo mol2 -at amberConvert antechamber format to Sybyl Mol2, and rename residue to LIG
