# Go Best Practices

Production patterns from Google, Uber, and the Go team. Updated for Go 1.25.

> Sub-skills: `skills/go-error-handling`, `skills/go-concurrency`, `skills/go-testing`, `skills/go-performance`, `skills/go-code-review`, `skills/go-linting`, `skills/go-project-layout`, `skills/go-security`. Deep-dive references in `references/`.

## Core Principles

Readable code prioritizes these attributes in order:

1. **Clarity**: purpose and rationale are obvious to the reader
2. **Simplicity**: accomplishes the goal in the simplest way
3. **Concision**: high signal to noise ratio
4. **Maintainability**: easy to modify correctly
5. **Consistency**: matches surrounding codebase

## Error Handling

> Full guide: `skills/go-error-handling/SKILL.md` | Reference: `references/error-handling.md`

- **Return errors, never panic** in production code
- **Wrap with `%w`** when callers need `errors.Is`/`errors.As`; use `%v` at boundaries
- **Keep context succinct**: `"new store: %w"` not `"failed to create new store: %w"`
- **Handle errors once**: don't log and return the same error
- **Error strings**: lowercase, no punctuation
- **Indent error flow**: handle errors first, keep happy path at minimal indentation
- **Use `errors.Join`** (Go 1.20+) for multiple independent failures
- **Sentinel errors**: `Err` prefix for vars, `Error` suffix for types

```go
if err != nil {
    return fmt.Errorf("load config: %w", err)
}
```

Generate and incrementally maintain an interactive architecture map plus a per-module code-quality audit (health scores 0-100, smell findings, lines-of-code, and a clickable dependency graph) for any codebase. Use when the user wants to visualize a project's functional modules, audit or score code quality, check whether the architecture map is stale / up to date, incrementally refresh it after code changes, or auto-fix the findings of a specific module. Module audits are run by independent subagents against a fixed rubric. Triggers: "architecture map", "module map", "audit the codebase", "scor

Semi Formal Reasoning

knot0-com/semi-formal-reasoning

Use for code verification, debugging, and deep code analysis without running tests. This skill should be used when the user asks to "verify my changes", "check my patch", "find the bug", "why does this test fail", "are these changes correct", "review this diff", or when analyzing code semantics that require tracing execution paths. It applies semi-formal structured reasoning from the Agentic Code Reasoning paper (Ugare & Chandra, Meta, 2026) to prevent unsupported claims and force evidence-based analysis.

Code Review

quanru/code-review-skill

Perform architecture- and maintainability-focused code reviews. Use when the user asks for code review, style review, refactoring feedback, or review of architecture, cohesion, coupling, TypeScript rigor, naming, tests, responsibility boundaries, or unnecessary abstractions.
