Covers idiomatic sequential Go 1.27: error handling (%w wrapping, errors.Join, errors.Is/As, errors.AsType), slog structured logging, generics (including 1.27 generic methods), small consumer-side interfaces, naming/style conventions, new(expr), and go fix modernizers. Does not cover goroutines/channels/errgroup/context concurrency (see go-concurrency), non-Go languages, or framework-specific code. Idiomatic sequential Go for 1.27. For anything touching goroutines, channels, errgroup, or context cancellation, use go-concurrency instead. Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name: 1. fuse-ai-pilot:explore-codebase - Map existing error/logging/interface patterns 2. fuse-ai-pilot:research-expert - Verify latest Go docs via Context7/Exa 3. mcpcontext7query-docs - Confirm stdlib signatures (errors, log/slog) After implementation, run fuse-ai-pilot:sniper for validation. -- | Feature | Description | |---------|-------------| | Error handling | Explicit if err != nil, %w wrapping, errors.Join, errors.AsType (1.26) | | Structured logging | log/slog stdlib — handlers, attrs, groups, LogValuer | | Generics | Type params, constraints, self-referenti
