Legacy Discovery
Use when starting work on an unfamiliar legacy project, inherited codebase, or large old system. Triggers when user says "understand this project", "what does this codebase do", "analyze this legacy system", "map this project", or wants to explore an existing codebase before making changes.
Legacy Safety Rails
Use when a legacy project needs test coverage, observability, feature flags, or rollback mechanisms before refactoring. Triggers when user says "add tests to this old code", "make this safe to refactor", "add guardrails", "protect this before changing it", or after legacy-doc-bootstrap has created docs.
Legacy Kickstart
Use when the user wants a guided, end-to-end AI modernization of a legacy project. Triggers when user says "AI化改造", "AI-friendly modernization", "modernize this project", "make this project AI-ready", "对这个项目进行AI改造", "help me modernize this codebase", or wants a one-click guided experience through discovery, documentation, and safety rails.
Legacy Refactor Plan
Use when planning actual code changes to a legacy project after guardrails are in place. Triggers when user says "refactor this module", "modernize this code", "plan the migration", "break this into tasks", or after legacy-safety-rails has established protection.
Legacy Doc Bootstrap
Use when a legacy project needs documentation created from scratch or existing implicit knowledge turned into structured docs. Triggers when user says "document this project", "create docs for this codebase", "write up the architecture", or after legacy-discovery has completed analysis.
Ai Handrail
Use when working with legacy projects, old codebases, or inherited systems that need modernization. Triggers when user mentions legacy code, old project, inherited codebase, technical debt, legacy refactoring, safe modernization, understanding an unfamiliar large codebase before making changes, AI化改造, AI-friendly modernization, make this project AI-ready, or modernize this project.
