Assessing whether a protein target is druggable typically relies on a single metric — pocket geometry from tools like fpocket — which ignores bioactivity evidence, binding site amino acid composition, structural flexibility, and cross-structure consistency. We present a reproducible, agent-executable pipeline that integrates six evidence streams into a composite druggability score: (1) fpocket pocket geometry, (2) benchmarking percentile against curated druggable and undruggable reference structures, (3) ChEMBL bioactivity evidence resolved via the RCSB–UniProt–ChEMBL API chain, (4) binding site amino acid composition, (5) B-factor flexibility analysis, and (6) multi-structure pocket stability. Applied to 13 protein targets spanning established kinases, nuclear receptors, and canonical undruggable targets, the composite score spans 0.051 (MYC, CHALLENGING) to 0.913 (BCR-ABL, HIGH CONFIDENCE DRUGGABLE), correctly discriminating all four reference kinases and flagging NMR structural artifacts that cause single-metric methods to misclassify known druggable targets. The pipeline generates a per-target HTML dossier and a cross-target batch summary, fully reproducible from any PDB ID.

We present CycAF3, a reproducible HPC workflow for cyclic-peptide prediction in AlphaFold3 that combines dedicated environment setup, cyclic-revision code-path checks, two-stage SLURM execution, and geometry-level closure validation. Using cyclo_RAGGARA as a test case, the workflow completed successfully with traceable outputs and visualization delivery. We show that cyclic metadata alone is insufficient and that terminal C–N geometric checks are required for reliable cyclic claims.
