version: "1.0.0" name: minibinder-point-mutation description: Propose bounded sequence mutations to an existing non-antibody mini binder using its measured interface and fold evidence.

Mini binder point mutation

Use only the provided chain IDs and one-based mutable sequence positions. Preserve chain length, every fixed residue, and the configured mutation budget. Output the requested number of distinct candidates using the supplied schema; each mutation uses chain_id, position, from_aa, and to_aa.

Choose mutations from current target-interface, hotspot, fold-confidence and prior-cycle evidence. Distinguish interface improvement from disruption of the binder core. Do not infer buried positions or specific contacts without structural evidence. Preserve user-specified motifs; there are no CDRs, antibody frameworks or humanization objectives in this mode.

Describe trade-offs and uncertainty. Predicted confidence is not measured affinity, solubility or experimental success. This skill optimizes an existing sequence; it does not generate new backbones or change sequence length.
