protein-structure-prediction

protein-structure-prediction is a skill for Claude Code from Team-yPark/skills. It costs 155 tokens per session (1,517 once invoked), scanned B, original, Unlicense.

A workflow for predicting and examining a protein's three-dimensional shape from its amino-acid sequence, the chain of building blocks that makes up a protein.

In plain words
What is it for?
Use it to find known structures, choose a suitable prediction model, obtain a structure, and interpret confidence results.
Why use it?
It first checks whether an experimental or existing predicted structure is available, avoiding unnecessary prediction work.

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 B, and why

protein-structure-prediction scanned grade B with 2 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 12d 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.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Protein Structure Prediction from Sequence

Turn an amino-acid sequence into a usable 3D structure: pick a model for the job, obtain the structure (look it up before predicting), and interpret it through its confidence scores. Background biochemistry and model facts live in the knowledge base (be-domain-expert, biochemistry/ and bioinformatics/protein-structure/); this skill is the practical how-to.

First: does the structure already exist?

Predicting is often unnecessary. Check, in order:

  1. PDB (rcsb.org) — an experimental structure (X-ray/cryo-EM/NMR) beats a prediction; search by sequence (BLAST) or ID.
  2. AlphaFold DB (alphafold.ebi.ac.uk) — 200M+ precomputed AF2 models, keyed by UniProt accession. If your protein is there, download it (.pdb + PAE JSON) instead of re-running.
  3. ESM Metagenomic Atlas — for metagenomic/orphan sequences.

Only predict when there is no suitable existing model, the sequence is novel (variant, designed, chimera), or you need a complex/ligand state not in a DB.

Choose the model

Situation Use Why
Single protein, has homologs (deep MSA) ColabFold / AlphaFold2 highest single-chain accuracy
Protein complex (multi-chain), or with DNA/RNA/ligand/ion AlphaFold3 or Boltz model the whole assembly, not lone chains
Open/local complex + ligand, at scale Boltz (Boltz-1/2) open-source AF3-class; runs locally
Many sequences / need speed / orphan or designed protein ESMFold no MSA, ~10× faster, better on shallow-MSA
Just a quick single fold, no setup ESMFold API or ColabFold notebook zero install

Decision rationale (MSA depth, complexes, speed/accuracy trade-offs) is in the knowledge base — consult be-domain-expert if unsure which applies.

Get a structure

Prefer a hosted notebook/API for one-offs; local install for batches.

ColabFold (AF2, MSA via MMseqs2) — the standard accessible AF2:

# local: github.com/sokrypton/ColabFold  (needs GPU + colabfold_batch)
colabfold_batch input.fasta out_dir/    # FASTA: one record per chain
#   complex: put chains in one record separated by ':'  (SEQ1:SEQ2)

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.

protein-structure-prediction is a skill published in the GitHub repository Team-yPark/skills (2 stars, last pushed 1mo ago), licensed Unlicense. It adds 155 tokens to every session and 1,517 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
