baekenough/oh-my-customcode
Go backend patterns from Uber style and standard layout
mir-backend-go-echo
anantbhandarkar/make-it-right
Make It Right (Echo module). Echo web framework reliability augmentation for Go backends. Use alongside mir-backend and mir-backend-go when the target stack is Echo — adds the mechanical footguns the runtime-agnostic tiers deliberately omit: echo.Context is request-scoped and must not be retained across the handler boundary or passed to a goroutine without copying values, Bind + Validator separation (Bind alone does not validate — you must install a custom Validator and call Validate explicitly), middleware ordering (Recover() before your middleware), HTTPErrorHandler for consistent error shape, and graceful shutdown via e.Shutdown(ctx). TRIGGER only when the Go backend uses the Echo framework — building, reviewing, or debugging an Echo 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 Echo library mechanics. SKIP for Gin, Fiber, chi, stdlib net/http, or any non-Echo stack, and for non-Go runtimes.
mir-backend-go-fiber
anantbhandarkar/make-it-right
Make It Right (Fiber module). Fiber web framework reliability augmentation for Go backends. Use alongside mir-backend and mir-backend-go when the target stack is Fiber — adds the mechanical footguns the runtime-agnostic tiers deliberately omit: fiber.Ctx and all its values (Body, Params, Headers) are pooled and reused after the handler returns (retaining them causes data corruption across requests), fasthttp incompatibility with net/http middleware and ecosystem, the Immutable setting that controls whether returned strings reference reused buffers, and graceful shutdown via app.ShutdownWithContext. TRIGGER only when the Go backend uses the Fiber framework — building, reviewing, or debugging a Fiber handler, middleware, or route. 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 Fiber library mechanics. SKIP for Gin, Echo, chi, stdlib net/http, or any non-Fiber stack, and for non-Go runtimes.
go-go-go
pfalkowski/skills
End-to-end "ship it" driver — takes whatever state the repo is in (ideas, uncommitted work, open tasks, stalled PR) and drives forward to a raised PR without stopping for low-stakes decisions. Applies whatever-mode, completes unfinished work via nightshift or a focused loop, picks the cheapest model tier that fits each step, commits, pushes, and opens the PR. Escalates autonomously to extreme mode when needed: ralph-loop as persistence engine with either a farm of parallel Haiku workers (mechanical/breadth tasks) or a sequential Opus chain (hard reasoning/depth tasks) — shape chosen at own discretion. Use when the user says "go go go", "just ship it", "make it happen", "finish and PR this", or wants zero-friction end-to-end delivery.
