## Task Run a brainstorm on `$ARGUMENTS`. **Default (no flags): conversational mode** — lightweight ping-pong between user and orchestrating assistant; zero agents spawned; escalations (research / panel / synthesis) proposed inline with cost transparency and consented to per step. **Flag-driven (`--panel` | `--deep` | `--research`): autonomous fan-out** — runs the full panel phases 2-7 as committed below. Either mode can produce a schema-compliant `BRIEF.md` that hands off to `/aih-plan --from-brainstorm` or `/aih-milestone --from-brainstorm`. No code edits, no branches. Read-only exploration. $ARGUMENTS ## Load Context (silently) - Read `.aihaus/memory/MEMORY.md` and referenced files. - Read `.aihaus/project.md` (stack, conventions). - Read `.aihaus/decisions.md` — ADR-001 (single-writer) is binding for this skill. - Read `.aihaus/knowledge.md` if present. ## Inter-agent Conventions — Cite, Don't Duplicate Turn-log schema, first-line header discriminator, and single-writer rule live in `/aih-help` under **Inter-agent Conventions**. This skill is the sole writer on `CONVERSATION.md` for the brainstorm dir. Every turn block is appended via heredoc by this skill after the subagent returns. No panelist, no contrarian, no synthesizer ever writes `CONVERSATION.md`. ## Argument Parsing Parse from `$ARGUMENTS`: - Quoted `<topic>` (required; anything without a `--` prefix). - `--panel "a,b,c"` (optional; comma-separated agent `name` values; max 5). - `--deep` (optional; enables R
