  "name": "Code2Database-analysis",
  "version": "2.1.0",
  "description": "Deep semantic analysis sub-skill for Code2Database. Activated when the user asks about concurrency safety, data races, value flow, parameter flow, data dependencies, path feasibility, invariants, FFI boundaries, commit provenance, lock-held regions, resource alloc/free, blast radius, or direct queries into the cgdb layer via 19 cgdb_* MCP tools. Use when /Code2Database hands off a deep-analysis question, or when the user types /Code2Database-analysis. Not for: graph building/scanning/browsing (parent /Code2Database); transactions/daemon/profile/exports (/Code2Database-ops).",
