Data Migration Expert Skill for Claude

Use this agent when reviewing PRs that touch database migrations, data backfills, or any code that transforms production data. This agent validates ID mappings against production reality, checks for swapped values, verifies rollback safety, and ensures data integrity during schema changes. Essential for any migration that involves ID mappings, column renames, or data transformations. <example>Context: The user has a PR with database migrations that involve ID mappings. user: \"Review this PR that migrates from action_id to action_module_name\" assistant: \"I'll use the data-migration-expert agent to validate the ID mappings and migration safety\" <commentary>Since the PR involves ID mappings and data migration, use the data-migration-expert to verify the mappings match production and check for swapped values.</commentary></example> <example>Context: The user has a migration that transforms enum values. user: \"This migration converts status integers to string enums\" assistant: \"Let me have the data-migration-ex...

Biorxiv Database

by christophacham

×4

Efficient database search tool for bioRxiv preprint server. Use this skill when searching for life sciences preprints by keywords, authors, date ranges, or categories, retrieving paper metadata, downloading PDFs, or conducting literature reviews.

Access BRENDA enzyme database via SOAP API. Retrieve kinetic parameters (Km, kcat), reaction equations, organism data, and substrate-specific enzyme information for biochemical research and metabolic pathway analysis.

Access ClinPGx pharmacogenomics data (successor to PharmGKB). Query gene-drug interactions, CPIC guidelines, allele functions, for precision medicine and genotype-guided dosing decisions.

Query NCBI ClinVar for variant clinical significance. Search by gene/position, interpret pathogenicity classifications, access via E-utilities API or FTP, annotate VCFs, for genomic medicine.

Access COSMIC cancer mutation database. Query somatic mutations, Cancer Gene Census, mutational signatures, gene fusions, for cancer research and precision oncology. Requires authentication.

Query Ensembl genome database REST API for 250+ species. Gene lookups, sequence retrieval, variant analysis, comparative genomics, orthologs, VEP predictions, for genomic research.

Query openFDA API for drugs, devices, adverse events, recalls, regulatory submissions (510k, PMA), substance identification (UNII), for FDA regulatory data analysis and safety research.

Query NCBI Gene via E-utilities/Datasets API. Search by symbol/ID, retrieve gene info (RefSeqs, GO, locations, phenotypes), batch lookups, for gene annotation and functional analysis.
