molclaw-openawsem-tool

molclaw-openawsem-tool is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 65 tokens per session (1,617 once invoked), scanned A, original, MIT.

A protein simulation tool that runs OpenAWSEM, a coarse-grained model for studying how proteins move and fold, and extracts representative frames from the resulting trajectory.

In plain words
What is it for?
Use it for annealing or constant-temperature simulations from a simulation directory, PDB file, or PDB identifier, then select representative trajectory frames.
Why use it?
It provides simulated protein structures for screening and ensemble analysis when a single static structure is not enough.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

molclaw-openawsem-tool scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OpenAWSEM Simulation and Trajectory Extraction

Invocation

Use the exact tool name and parameter schema exposed by the current harness. Tool names in SDK examples below are raw MCP names, not model-facing aliases. Local files must be uploaded with molclaw-file-transfer before a server tool can use them. Repair PDB inputs first when the workflow requires it.

Usage

1. OpenAWSEM Simulation

The description of tool openawsem_sim.

Run OpenAWSEM coarse-grained protein simulation for annealing or NVT workflows in structure screening and folding studies.
Args:
  sim_dir (str|None): Simulation directory containing *-openmmawsem.pdb or *_openmmawsem.pdb, default None.
  pdb (str|None): PDB file path or PDB ID used by awsem_create when sim_dir is not provided, default None.
  steps (float): Simulation step count, default 1e5.
  mode (str): Temperature control mode in {annealing, nvt}, default annealing.
  temperature (float): NVT temperature in Kelvin passed to source script argument --temperature, default 300.0.
  platform (str): OpenMM platform in {CPU, CUDA, OpenCL}, default CPU.
  use_frag_mem (bool): Whether to use fragment memory instead of single memory, default False.
  compute_q (bool): Whether to enable Q-value related terms when available, default False.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

molclaw-openawsem-tool is a skill published in the GitHub repository InternScience/MolClaw (38 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 1,617 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
