chai1 SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
chai1 from yichen-zju/claude-for-research is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yichen-zju/claude-for-research/chai1@git:20261014.9f2a5e0Pins git:20261014.9f2a5e0 in mdr.lock. Pin the fingerprint instead.

Run or prepare Chai-1 structure predictions for biomolecular complexes. Use when a task asks for Chai-1 inputs, multimers, ligand/nucleic acid structure prediction, or confidence review.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chai-1 Use this skill for Chai-1-style biomolecular structure prediction and review. Workflow: 1. Convert the research question into an input manifest with chains, sequences, ligands, nucleic acids, templates, restraints, and seeds. 2. Verify the available execution path before running: local model, managed endpoint, Modal job, SSH host, or documented remote API. 3. Capture package/model version, exact input manifest, hardware, command or request body, and all raw output files. 4. Save structure files and confidence artifacts in the active output folder (`outputs/`). 5. Review chain coverage, interface confidence, ligand plausibility, stereochemistry warnings, and conflicts with known structures. Use the structure as evidence only after the provenance and confidence checks are attached.

How to install
mdr add yichen-zju/claude-for-research/chai1@sha256:fc2d5041da10e1ecThe line at the top of this page pins the label git:20261014.9f2a5e0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
