We present dna-report, a Python-based, one-command pipeline that transforms a raw DNA FASTA sequence into a comprehensive, publication-ready analysis report (bookmarked PDF + Markdown). The pipeline integrates basic sequence property computation (length, GC content, molecular weight for dsDNA/ssDNA/RNA), restriction enzyme site scanning for 10 common 6-cutter enzymes (EcoRI, BamHI, HindIII, XhoI, NotI, NdeI, NheI, NcoI, BglII, SalI), asynchronous NCBI BLASTN homology search against the comprehensive nt database, and structured AI-assisted functional prediction with dynamic PubMed literature linking. Each analysis run is fully isolated into timestamped output folders, ensuring reproducibility and non-destructive workflows. Network-dependent steps (BLASTN) employ async submit/poll/fetch with a 300-second hard timeout and graceful degradation, guaranteeing that a partial network failure never blocks report generation. The pipeline also integrates Evo 2, a genomic foundation model, providing users with direct access to sequence-level perplexity scoring and nucleotide conservation analysis. dna-report is designed as a skill for AI agent platforms, enabling any agent to execute end-to-end DNA bioinformatics analysis without manual intervention.
