solublempnn

solublempnn is a skill for Claude Code, Codex from aipoch/open-science. It costs 96 tokens per session (1,072 once invoked), scanned A, original, Apache-2.0.

A protein-design model that chooses amino-acid sequences for a given protein backbone, using training data from proteins that dissolve well in cells. It is a retrained version of ProteinMPNN, a tool for designing protein sequences from 3D structures.

In plain words
What is it for?
Use it to redesign a protein backbone for better soluble production in another organism. It can generate sequences for one structure or for larger batches, using a CPU or GPU.
Why use it?
It helps when standard ProteinMPNN designs clump together or become inclusion bodies, which are unwanted deposits inside cells. Its training shifts results toward sequences more likely to remain soluble in a host cell.

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

solublempnn 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.

SolubleMPNN

SolubleMPNN is not a separate package — it is the ProteinMPNN architecture retrained on a soluble-PDB subset, which shifts the output distribution away from the surface hydrophobics that the full-PDB model happily places (because many of them are buried at crystallographic or membrane interfaces in the training set). Reach for it when the goal is soluble yield in a heterologous host; stick with proteinmpnn when native-like recovery matters more, since the soluble prior trades a few points of recovery for the surface bias. Code and weights are MIT (github.com/dauparas/ProteinMPNN, soluble_model_weights; also exposed via github.com/dauparas/LigandMPNN). The model is small enough to run on CPU — for a handful of sequences on one backbone that is seconds and usually faster than dispatching; a GPU helps for batched campaigns. Either way the repo is cloned in-job (no PyPI dist; checkpoints bundled).

Running it

pip install torch numpy   # if not already present
git clone --depth 1 https://github.com/dauparas/ProteinMPNN.git proteinmpnn
cd proteinmpnn
python protein_mpnn_run.py \
  --pdb_path backbone.pdb --pdb_path_chains "A" \
  --out_folder out --num_seq_per_target 16 \
  --sampling_temp "0.1" --use_soluble_model

The runner uses repo-relative imports, so the cd line is load-bearing — invoking the script by absolute path from elsewhere fails with ModuleNotFoundError. If you want threaded designed-sequence PDBs as well, the LigandMPNN runner accepts --model_type soluble_mpnn (see ligandmpnn for that path; it needs ProDy in addition to torch). The flag surface is otherwise identical to proteinmpnn (or ligandmpnn for the second form), including the string-typed temperature and the fixed-position JSONL keyed by PDB stem — see proteinmpnn for the parsing quirks. The repo ships soluble weights at v_48_010 and v_48_020 only; asking for --model_name v_48_002 --use_soluble_model errors on a missing checkpoint, so leave --model_name at its default.

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.
