Covers clean architecture patterns, error handling, GORM database access, JWT/tenant security, Zap logging, Fiber handlers, gRPC, NATS events, and testing. Triggers when a developer asks to create a Go service, write a handler or usecase, fix a Go bug, review Go code, add an API endpoint, write a migration, or work with the XynPOS backend codebase. Also use when questions like "how do I structure this service" or "what's the right way to handle errors" come up.
django
iam-nazmul/drcr

Use when Codex needs to build, review, or refactor backend code in this repository, especially models, validations, controllers, forms, services, queries, jobs, policies, mailers, migrations, and RSpec coverage, and when backend performance concerns such as N+1 queries, eager loading, query shape, callback side effects, and job boundaries must be checked carefully.
rails-gem-finder
fadynaffa3/railsonclaude
Search for battle-tested Ruby gems and Rails libraries instead of building from scratch. Uses RubyGems, GitHub, and community sources to find well-maintained, popular, and license-compatible gems for any Rails problem.
mir-backend-go
anantbhandarkar/make-it-right
Make It Right (Go runtime tier). Go 1.22+ runtime reliability footguns shared across every Go backend framework (Gin, Fiber, Echo, chi, stdlib net/http) — distinct from the generic backend gates and from any one framework's mechanics. Covers: goroutine leaks (the #1 Go reliability bug), context propagation and cancellation, data races on shared state, channel ownership rules, goroutine-level panic recovery, the nil-interface/nil-pointer trap, defer-in-loop resource buildup, slice aliasing and backing-array mutation, error wrapping discipline, and sync.WaitGroup misuse. TRIGGER when the backend runtime is Go — sits between mir-backend (generic) and the framework module (e.g. mir-backend-go-gin). SKIP for Python/Node/JVM/Rust/.NET/Ruby/PHP/BEAM runtimes (each has its own mir-backend-<runtime> tier), and for framework-library mechanics (those live in the framework module).

Use this skill when building self-contained single-binary applications, implementing SPA with Go backend, setting up cross-platform deployable full-stack projects, or configuring static file serving with Go standard library net/http.
Go
clawic/skills
Writes, debugs, and reviews Go: goroutine leaks, data races, nil interfaces, slices and maps, go.mod, and net/http. Use when Go panics or misbehaves — "all goroutines are asleep - deadlock!", "concurrent map writes", "send on closed channel", "assignment to entry in nil map", or a WARNING: DATA RACE from `go test -race`; when a goroutine, timer, or connection leaks and memory climbs; when a service hangs for want of a timeout; when errors.Is or errors.As stops matching after a %v wrap; when a slice mutates its parent, a map iterates in a new order, or a typed nil returned as error compares non-nil; when go.mod, go.sum, workspaces, replace, or a /v2 path fight over dependencies; when cross-compiling, cgo, build tags, go:embed, or a static container binary fail; when tests are flaky under -race or -parallel or benchmarks lie; when GOGC, GOMEMLIMIT, GOMAXPROCS, or escape analysis need tuning; or when writing handlers, CLIs, database access, or generics. Not for Kubernetes operators or framework internals.
go
background-craft/hydrant-skills
Implement a Hydrant issue end-to-end — fetch context, set up the branch, plan, build, verify, and commit. Use when the user asks for `/go`, says "go HYD-123", "implement HYD-123", or wants implementation started on a specific issue. The "do the work" command in the lifecycle.
gostack
developerakx/skills
Go backend service architecture: fx DI, Huma+Fiber HTTP, SQLC database access, pgx pools, atomic-string money values, feature-based directory layout. Opinionated defaults for building production Go services. Use when building Go backend services, adding features to a gostack-style codebase, or invokes /gostack.
personal-tutor-rust-backend

Produces structured reports with cited sources. Use for complex topics that need synthesis across multiple sources.
mir-backend-go-gin
anantbhandarkar/make-it-right
Make It Right (Gin module). Gin web framework reliability augmentation for Go backends. Use alongside mir-backend and mir-backend-go when the target stack is Gin — adds the mechanical footguns the runtime-agnostic tiers deliberately omit: *gin.Context is request-scoped and must be copied before passing to a spawned goroutine, binding and validation discipline (ShouldBindJSON + struct tags, separate request vs DB model), middleware ordering (Recovery before your handlers), missing graceful shutdown wiring (http.Server.Shutdown on SIGTERM), and route group auth guard placement. TRIGGER only when the Go backend uses the Gin framework — building, reviewing, or debugging a Gin handler, middleware, or router. Always loads TOGETHER WITH mir-backend (generic gates) and mir-backend-go (Go runtime concerns: goroutine leaks, context propagation, data races, channel rules, typed-nil, defer-in-loop, slice aliasing, error discipline, WaitGroup); this module only adds Gin library mechanics. SKIP for Fiber, Echo, chi, stdlib net/http, or any non-Gin stack, and for non-Go runtimes.
