Coding standards, frameworks, refactoring, and code review (16.4K skills)
Turn reviewed wiki knowledge into a reusable Agent Skill package with SKILL.md, supporting references, and source records. Output goes to a review directory so a person can inspect it before choosing to install it.
Investigate Go crashes, hangs, intermittent failures, and unexpected behavior through reproducible tests and measured evidence. Use race detection, Delve debugging, and pprof diagnostics to trace root causes, then verify fixes and guard against regressions.
Choose and review Go design patterns for APIs and application structure. Get guidance on constructors, explicit initialization, resource cleanup, graceful shutdown, timeouts, and retries, with patterns matched to project requirements and the developer’s preferred architecture.
Write and review Go error handling so failures carry useful context and are handled once. Covers error creation, wrapping, inspection, panic usage, and structured logging, where named fields help organize and search production logs.
Restructure existing Go code while preserving its behavior. Uses gopls, Go's code analysis tool, to map affected code and apply changes, with targeted tests and small pull requests for renaming, extracting functions, and moving code between packages.
Build and extend Go command-line tools with spf13/cobra. Organizes commands and options, validates arguments, adds shell completion suggestions, customizes help, and tests command behavior with captured output and isolated command instances.
Build, extend, or review Go command-line tools with clear commands, flags, and configuration priorities. It guides output formats, exit codes, shell completion, cancellation, and tests so tools behave predictably in scripts and terminals.
Write and review documentation for Go libraries and applications, from code comments and README files to installation guides and changelogs. Add runnable examples and structured project summaries that help readers and AI agents understand how to use the code.
Use samber/mo in Go to represent missing values, failures, and alternative value types explicitly. Learn to choose Option, Result, or Either and combine processing steps, including pipelines where each step changes the value's type.
Implement layered configuration in Go with spf13/viper, combining command flags, environment variables, and configuration files under a fixed priority order. Covers mapping values into structs, reloading changed files, and keeping configuration state separate across tests.
Build Go application initialization with google/wire, which generates constructor calls from declared dependencies. Covers reusable provider groups, interface bindings, cleanup functions, and keeping generated code synchronized so missing dependencies surface during generation.
Build in-memory caches in Go with samber/hot to reduce repeated backend reads. Choose eviction rules, set expiration and capacity, load missing entries, and monitor cache behavior while accounting for memory limits and loading failures.
Improve Go code after profiling identifies a bottleneck. This skill guides memory allocation, CPU, caching, and garbage collection changes, with benchmark comparisons to check results. It also supports performance reviews of functions, packages, and services.
Design and review Go structs and interfaces with clear responsibilities. Get guidance on small interfaces, embedding, dependency injection—passing in components a type needs—field tags, safe type checks, and pointer or value receivers.
Helps choose and review names in Go code, covering packages, functions, types, constants, errors, and tests. Provides conventions and examples for capitalization, acronyms, constructors, and repeated wording to make naming decisions consistent.
Selects and loads relevant Go skills for coding, review, debugging, and setup tasks. It combines complementary guidance, explains overlapping skill roles, and can configure project agent instructions to load Go skills consistently.
Organize Go projects with directory layouts, naming rules, and configuration files suited to their size and purpose. Supports command-line tools, libraries, services, and workspaces for developing several related modules together.
Helps wire Go applications with uber-go/dig using dependency injection, which supplies the components each function needs. Covers constructor registration, named values, groups, and validation so startup dependencies can be organized and checked in tests.
Create and review Go API documentation with swaggo/swag. Adds comments describing inputs, responses, and authentication, generates machine-readable API specifications, and connects Swagger UI so API users can inspect the documented endpoints.
Build GraphQL APIs in Go with gqlgen or graphql-go. Covers schemas, resolvers that fetch field data, authentication, and live subscriptions, plus request-level data batching and query limits to address excessive database calls and resource use.
Build Go logging pipelines with samber/slog-* packages to control log volume, mask personal information, and route records to different destinations. It also guides HTTP request logging and shutdown handling for destinations that buffer records.
Review older Go code and plan updates to language features, standard libraries, tests, and CI. The skill checks the project's Go version, prioritizes safety and correctness, and guides changes with linting and tests.
Look up published Go packages with godig, a client for pkg.go.dev. Retrieve function signatures, documentation, examples, available versions, licenses, known vulnerabilities, and importing packages through read-only queries that require no authentication.
Design how Go requests carry cancellation signals, time limits, and request metadata through application layers. Helps investigate work that continues after cancellation, choose suitable context types, and separate background tasks from the request lifecycle.
