Agent Skills: integration-analysis

Give it a few starting points — it discovers the full ecosystem by tracing integration surfaces in code and docs, clones what it doesn't have locally, then thoroughly analyzes how every system works and connects. Produces a layered implementation plan (L0-L3) with functionality tiering (T1/T2/T3/PRUNE) and generates dependency-ordered, technology-agnostic epics and stories so the team can build incrementally — MVP first, then progressively more capability.
