vc-debug is a Claude Code skill that enforces systematic debugging with mandatory root-cause analysis before any fixes are applied. It bundles 10 techniques: a four-phase debugging framework, backward call-stack tracing with `scripts/find-polluter.sh` for test-pollution bisection, defense-in-depth layer validation, a verification protocol that requires fresh evidence before claiming completion, a five-step system investigation methodology, log and CI/CD analysis via the `gh` CLI, performance diagnostics covering queries and resource utilization, structured reporting, multi-step investigation tracking through Task tools, and frontend visual verification via Chrome MCP. The skill applies to code bugs, test failures, CI/CD pipeline failures, performance degradation, and multi-component system incidents. It integrates with `sqlite3`, `drizzle-kit studio`, `vc-scout`, and `vc-agent-browser` for full-stack diagnostic coverage.
