Apply modern Go syntax based on this repository's Go version. Use when writing, editing, or reviewing Go code, or when the user asks for modern Go guidelines.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modern Go Guidelines ## Detected Go Version !`grep -rh "^go " --include="go.mod" . 2>/dev/null | cut -d' ' -f2 | sort | uniq -c | sort -nr | head -1 | xargs | cut -d' ' -f2 | grep . || echo unknown` ## How to Use This Skill DO NOT search for go.mod files or try to detect the version yourself. Use ONLY the version shown above. **If version detected (not "unknown"):** - Say: "This project is using Go X.XX, so I’ll stick to modern Go best practices and freely use language features up to and including this version. If you’d prefer a different target version, just let me know." - Do NOT list features, do NOT ask for confirmation **If version is "unknown":** - Say: "Could not detect Go version in this repository" - Use AskUserQuestion: "Which Go version should I target?" → [1.23] / [1.24] / [1.25] / [1.26] **When writing Go code**, use ALL features from this document up to the target version: - Prefer modern built-ins and packages (`slices`, `maps`, `cmp`) over legacy patterns - Never use features from newer Go versions than the target - Never use outdated patterns when a modern alternative is available --- ## Features by Go Version ### Go 1.0+ …

How to install
mdr add codeready-toolchain/tarsy/use-modern-go@sha256:2a075f2ded6fe990The line at the top of this page pins the label git:20260818.4293a53, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
