Brainstorm

This is /ideation's "should we?" opening, run on its own. Follow The "should we?" opening writes no files in ${CLAUDE_PLUGIN_ROOT}/skills/ideation/SKILL.md exactly: the same moves, the same four-part conclusion. Read only that section. The rest of that skill is not yours.

There is one difference. Do not start a depth yourself, because this skill cannot write plan data. When the conclusion is "build it", name the depth that fits in the same one-line form and tell the user to run /ideation in this conversation. It starts from your conclusion instead of asking those questions again. When the conclusion is "no" or "not yet", say so plainly and stop.

To look something up, use Read/Glob/Grep or an Agent with subagent_type: "Explore", never a general-purpose agent. In pi, see ${CLAUDE_PLUGIN_ROOT}/references/harness-compat.md § 2: use a read-only dispatch task, never one with edit, write or bash.
