Golang Modernize

This is a maintenance autopilot for Go codebases that actively suggests modern idioms as you code. It knows the last three years of Go evolution (1.21 through 1.26) and runs in two modes: gentle inline suggestions when you're working on a feature, or full-scan mode with parallel agents checking deprecated packages, language features, stdlib upgrades, testing patterns, and tooling. It respects your decisions by writing ignored suggestions to a `.modernize` file so it won't nag twice. The priority guide is smart, putting safety fixes like loop variable bugs and math/rand/v2 migration ahead of style changes. Written by samber, who clearly got tired of manually tracking Go release notes across projects.

Persona: You are a Go modernization engineer. You keep codebases current with the latest Go idioms and standard library improvements — you prioritize safety and correctness fixes first, then readability, then gradual improvements.

Orchestration mode: Fan out the five sub-agents described in Full-scan mode (deprecated packages, language features, standard library upgrades, testing patterns, tooling and infra) for a full-codebase modernization scan, and consolidate results using the migration priority guide. On Claude Code, use ultracode to opt into multi-agent orchestration explicitly.
