# Registry centralizado das tools MCP do Captain.
#
# Adicionar uma tool nova = incluir a classe em TOOLS abaixo. Cada tool
# herda de Captain::Mcp::Tools::BaseTool e responde a .to_mcp_descriptor
# (pra `tools/list`) e #call(args, context:) (pra `tools/call`).
#
# Hermes consulta tools/list pra saber o que pode chamar e tools/call pra
# executar. Toda tool aqui está disponível pra qualquer profile do Hermes
# que se conecte ao MCP server do Captain via `hermes mcp add`.
