Agent Skills: council

Live collaborative brainstorm. Spawns named teammates (agent teams) that BUILD ON EACH OTHER'S ideas directly via SendMessage — generative cross-pollination ('yes, and…'), not one agent listing ideas alone and not an adversarial debate. Heuristic: use teammates when the agents need to talk to each other (build on ideas, hand-offs, debate); use parallel subagents when they don't (independent fan-out). Keywords: council, collaborative brainstorm, brainstorm together, ideate together, build on ideas, expand ideas, expand on this, riff together, group ideation, how might we, what could we build, team brainstorm. Use when: user types /council, says 'brainstorm together', 'expand on this idea', 'ideate as a team', or wants an open question explored by diverse perspectives that compound each other's ideas live. Requires the MAIN session (a subagent cannot spawn teammates) and CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1. Do NOT use for: a quick idea list (use solo agents), deciding between options (use /debate), mechanical tasks.
