From 25601ba758f93a8aa7fc9b0a81256a3b1df026f0 Mon Sep 17 00:00:00 2001 From: Molecule AI SDK Lead Date: Tue, 21 Apr 2026 01:00:38 +0000 Subject: [PATCH] feat(cli): implement cmd/molecule/main.go with full command tree - Root command: --output, --verbose, --config flags - Workspace subcommands: create/list/inspect/delete/restart/delegate/audit - Agent subcommands: list/inspect/send/peers - Platform subcommands: audit/health - Config subcommands: list/get/set/init/view - Exit codes 0/1/2, errors to stderr, text/json/yaml output - Viper config file support, Gin mode (verbose = debug, silent = release) Co-Authored-By: Claude Sonnet 4.6 --- cmd/molecule/main.go | 507 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 507 insertions(+) create mode 100644 cmd/molecule/main.go diff
