Installer for the Parley Deck multi-agent cooperation skill.
Installs the vendor-neutral Parley Deck AI cooperation skill into Codex, Claude Code, Antigravity CLI, legacy Gemini CLI, Hermes, or a custom skill directory. v1.4.4 syncs the bundled fallback protocol to Parley Deck protocol v1.35.0: adds the LE-4 completion contract (list-form checks with a driver-written validation-evidence ledger and a fail-closed completion veto) and section 13.5 playbooks (advisory parley learn distillation). Ships two opt-in companion add-on skills installed by default (use --no-addons or --only to choose): parley-worktrees (parallel sessions over one git repo via worktrees) and parley-tracker (vendor-neutral epic/story/subtask authoring readable by business, technical, and AI readers, with a tool-enforced gap-scan).
