go-core-idioms skillA
go-core-idioms is agent-read markdown (skill) from fusengine/agents: Use when writing or reviewing idiomatic sequential Go — error handling, slog logging, generics, interfaces, style. Not for concurrency (go-concurrency)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective> Covers idiomatic sequential Go 1.26: error handling (%w wrapping, errors.Join, errors.Is/As, errors.AsType), slog structured logging, generics, 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. </objective> # Go Core Idioms Idiomatic sequential Go for 1.26. For anything touching goroutines, channels, `errgroup`, or `context` cancellation, use **go-concurrency** instead. ## Agent Workflow (MANDATORY) 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. **mcp__context7__query-docs** - Confirm stdlib signatures (errors, log/slog) After implementation, run **fuse-ai-pilot:sniper** for validation. --- ## Overview | Feature | Description | |---------|-------------| | **Error handling** | Explicit `if err != nil`, `%w` wrapping, `errors.Join`, `errors.AsType` (1.26) | …

How to install
mdr add fusengine/agents/go-core-idioms@git:20260904.5f1d30fmdr add fusengine/agents/go-core-idioms@sha256:85730689ab6bfc96Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
