Generates detection scripts and evidence-based upgrade reports to help teams upgrade Rails apps sequentially from 7.0 through 8.1.1, with breaking-change scans,
Rails Upgrade Assistant provides a stepwise, evidence-driven workflow for upgrading Rails applications. It can generate a tailored detection script that scans a project's codebase for version-specific breaking changes, parse the findings produced by that script, and then produce two deliverables: a Comprehensive Upgrade Report (with OLD vs NEW code examples, file:line references, testing and rollback plans) and an app:update Preview showing exact configuration diffs. The skill emphasizes sequential, non-skipping upgrades and flags custom code with explicit warnings.
Use this skill when you need to plan or execute a Rails version upgrade (single-hop or multi-hop). Trigger it when asking to upgrade a Rails app, requesting breaking-change analysis for a specific Rails version, or when you can run and share a findings.txt output from a detection script.
Compatible with coding assistants and agent tool integrations that can run shell scripts and read project files (Claude Code, Copilot/Codex-style assistants, agents with file-access MCP servers).
