## Summary

AI coding agents often generate outdated Go patterns because older syntax dominates training data and new features fall past model cutoffs. To address this gap, the GoLand team released Modern Go Guidelines, an open-source set of skills and CLI tools covering Go 1.0 through Go 1.27. The tool inspects a project's go.mod file or a specific version flag to supply only the language features and standard library additions compatible with that environment. Using a progressive disclosure approach, the CLI provides concise rule identifiers via a list command and expands into before-and-after examples through an explain command. This mechanism minimizes token consumption while helping agents produce up-to-date, compilable code without modifying project files.

## Context

AI coding agents frequently produce working Go code using outdated syntax or patterns because older code dominates their training data and newer language additions postdate training cutoffs.

## Approach / What changed

The GoLand team created Modern Go Guidelines, an open-source CLI tool and agent skill set covering Go 1.0 to 1.27. It reads the project go.mod file to filter out newer, incompatible versions and uses a two-step CLI approach (list for brief rule IDs and explain for detailed before-and-after code comparisons) to provide progressive, token-efficient context.

## Takeaways

- Modern Go Guidelines matches features directly against the go.mod version directive to prevent AI agents from generating incompatible newer code or wasting tokens on unusable syntax.
- The CLI tool employs progressive disclosure via list for brief guideline IDs and explain for deep before-and-after code replacements, keeping context compact.
- Installation runs via an agent plugin using go install into a local cache, requiring the Go toolchain on PATH without modifying the target project.
