Database management and queries
terraform-skill
by daymade
Operational traps for Terraform provisioners, multi-environment isolation, and zero-to-deployment reliability. Covers provisioner timing races, SSH connection conflicts, DNS record duplication, volume permissions, database bootstrap gaps, snapshot cross-contamination, Cloudflare credential format errors, hardcoded domains in Caddyfiles/compose, and init-data-only-on-first-boot pitfalls. Activate when writing null_resource provisioners, creating multi-environment Terraform setups, debugging containers that are Restarting/unhealthy after terraform apply, setting up fresh instances with cloud-init, or any IaC code that SSHs into remote hosts. Also activate when the user mentions terraform plan/apply errors, provisioner failures, infrastructure drift, TLS certificate errors, or Caddy/gateway configuration.
query-validation

Database schema understanding and relationship mapping. Use when exploring unfamiliar databases, documenting table relationships, identifying join paths, or generating ERD documentation for existing schemas.
programmatic-eda
by nimrodfisher
Systematic exploratory data analysis following best practices. Use when analyzing any dataset to understand structure, identify data quality issues (duplicates, missing values, inconsistencies, outliers), examine distributions, detect correlations, and generate visualizations. Provides comprehensive data profiling with sanity checks before analysis.
optimizing-ef-core-queries
by dotnet
"Optimize and improve the performance of slow Entity Framework Core (EF Core) queries: make them generate less SQL, make fewer database round-trips, and return results faster. Use whenever an EF Core or DbContext query or data-access path is slow or should be made faster — whether or not EF Core owns the database schema. For EF Core, not Dapper or raw ADO.NET."

80-20-review
by codewithmukesh
Focus code review effort on the 20% of code that causes 80% of issues. Prioritizes data access, security, concurrency, and integration boundaries over formatting and style. Uses blast radius scoring to determine review depth. Includes checkpoint schedules, critical path identification, and a batch review checklist. Load this skill when reviewing code, PRs, or architecture, or when the user mentions "review", "code review", "PR review", "what should I review", "review priorities", "blast radius", or "critical path".
ef-core
by codewithmukesh
