Use when planning legacy system migrations, codebase modernization, monolith decomposition, microservices consolidation, cross-language rewrites, or framework upgrades. Invoke for strangler fig pattern, incremental migration strategy, or refactoring roadmaps. Do NOT use for domain analysis (use domain-analysis), component sizing (use component-identification-sizing), or step-by-step decomposition plans (use decomposition-planning-roadmap).

1 medium severity finding. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.90). This skill's mandatory RESEARCH phase explicitly requires using "web search" and citing "verified external URL(s)" (see SKILL.md Core Principles and Research Phase: "Research current and target stacks — Use web search and context7" and references/research-phase.md), which means the agent will fetch and interpret open/public third‑party web content (including blogs/community posts) as evidence influencing migration decisions.
