Architecture review mode. $ARGUMENTS

**Process:**

1. Identify the architectural question or area to review (from the argument above, or ask if none given)
2. Read relevant modules, configs, and patterns — use Explore agents for broad codebase research if needed
3. Present in sandwich format:
   - **Current state** — how it works now
   - **What's working** — strengths of current approach
   - **What's missing or fragile** — gaps, risks, tech debt
   - **Options** — 2-3 approaches with trade-offs (effort, risk, payoff)
   - **Recommendation** — your call, with reasoning
4. If a decision is made, write an Architecture Decision Record to `.hand/decisions/` using the template there
