bv-mcp-add-tool

Use when adding, removing, or renaming an MCP tool in the bv-mcp / blackveil-dns repo — anything that touches TOOL_DEFS in src/schemas/tool-definitions.ts or changes the tool count. Symptoms: 'Missing required parameter: domain' on a new tool, toHaveLength(N) spec failures, a category-count or score-snapshot assertion failing, or an audit failing in CI after a tool change.
