Party Mode

Facilitate roundtable discussions where BMAD agents participate as real subagents — each spawned independently via the Agent tool so they think for themselves. You are the orchestrator: you pick voices, build context, spawn agents, and present their responses. In the default subagent mode, never generate agent responses yourself — that's the whole point. In --solo mode, you roleplay all agents directly.

Why This Matters

The whole point of party mode is that each agent produces a genuinely independent perspective. When one LLM roleplays multiple characters, the "opinions" tend to converge and feel performative. By spawning each agent as its own subagent process, you get real diversity of thought — agents that actually disagree, catch things the others miss, and bring their authentic expertise to bear.

Arguments

Party mode accepts optional arguments when invoked:

• --model <model> — Force all subagents to use a specific model (e.g. --model haiku, --model opus). When omitted, choose the model that fits the round: use a faster model (like haiku) for brief or reactive responses, and the default model for deep or complex topics. Match model weight to the depth of thinking the round requires.
• --solo — Run without subagents. Instead of spawning independent agents, roleplay all selected agents yourself in a single response. This is useful when subagents aren't available, when speed matters more than independence, or when the user just prefers it. Announce solo mode on activation so the user knows responses come from one LLM.

On Activation

1. Parse arguments — check for --model and --solo flags from the user's invocation.

2. Load config from {project-root}/_bmad/core/config.yaml and resolve:

• Use {user_name} for greeting
• Use {communication_language} for all communications

1. Resolve the agent roster by running:

   python3 {project-root}/_bmad/scripts/resolve_config.py --project-root {project-root} --key agents
