go-context

cxuu/golang-skills

Use when working with context.Context in Go — placement in signatures, propagating cancellation and deadlines, and storing values in context vs parameters. Also use when cancelling long-running operations, setting timeouts, or passing request-scoped data, even if they don't mention context.Context directly. Does not cover goroutine lifecycle or sync primitives (see go-concurrency).

SKILL.md

Go Context Usage

Compatibility: context has been in the standard library since Go 1.7.

Resource Routing

  • references/PATTERNS.md - Read when deriving contexts, checking cancellation, handling HTTP request contexts, or using typed context-value keys.

Context as First Parameter

Functions that use a Context should accept it as their first parameter:

func F(ctx context.Context, /* other arguments */) error
func ProcessRequest(ctx context.Context, req *Request) (*Response, error)

This is a strong convention in Go that makes context flow visible and consistent across codebases.

go-code-reviewcxuu/golang-skillsUse when reviewing Go code or checking code against community style standards. Also use proactively before submitting a Go PR or when reviewing any Go code changes, even if the user doesn't explicitly request a style review. Does not cover language-specific syntax — delegates to specialized skills.测试与安全1694go-testingcxuu/golang-skillsUse when writing, reviewing, or improving Go test code — including table-driven tests, subtests, parallel tests, test helpers, test doubles, and assertions with cmp.Diff. Also use when a user asks to write a test for a Go function, even if they don't mention specific patterns like table-driven tests or subtests. Does not cover benchmark performance testing (see go-performance).测试与安全1373go-lintingcxuu/golang-skillsUse when setting up linting for a Go project, configuring golangci-lint, or adding Go checks to a CI/CD pipeline. Also use when starting a new Go project and deciding which linters to enable, even if the user only asks about "code quality" or "static analysis" without mentioning specific linter names. Does not cover code review process (see go-code-review).测试与安全1299go-error-handlingcxuu/golang-skillsUse when writing Go code that returns, wraps, or handles errors — choosing between sentinel errors, custom types, and fmt.Errorf (%w vs %v), structuring error flow, or deciding whether to log or return. Also use when propagating errors across package boundaries or using errors.Is/As, even if the user doesn't ask about error strategy. Does not cover panic/recover patterns (see go-defensive).营销与写作1291go-concurrencycxuu/golang-skillsUse when writing concurrent Go code — goroutines, channels, mutexes, or thread-safety guarantees. Also use when parallelizing work, fixing data races, or protecting shared state, even if the user doesn't explicitly mention concurrency primitives. Does not cover context.Context patterns (see go-context).营销与写作1286go-documentationcxuu/golang-skillsUse when writing or reviewing documentation for Go packages, types, functions, or methods. Also use proactively when creating new exported types, functions, or packages, even if the user doesn't explicitly ask about documentation. Does not cover code comments for non-exported symbols (see go-style-core).营销与写作1281
