architecture

# /architecture > If you see unfamiliar placeholders or need to check which tools are connected, see [CONNECTORS.md](../../CONNECTORS.md). Create an Architecture Decision Record (ADR) or evaluate a system design. ## Usage ``` /architecture $ARGUMENTS ``` ## Modes **Create an ADR**: "Should we use Kafka or SQS for our event bus?" **Evaluate a design**: "Review this microservices proposal" **System design**: "Design the notification system for our app" See the **system-design** skill for detailed frameworks on requirements gathering, scalability analysis, and trade-off evaluation. ## Output — ADR Format ```markdown # ADR-[number]: [Title] **Status:** Proposed | Accepted | Deprecated | Superseded **Date:** [Date] **Deciders:** [Who needs to sign off] ## Context [What is the situation? What forces are at play?] ## Decision [What is the change we're proposing?] ## Options Considered ### Option A: [Name] | Dimension | Assessment | |-----------|------------| | Complexity | [Low/Med/High] | | Cost | [Assessment] | | Scalability | [Assessment] | | Team familiarity | [Assessment] | **Pros:** [List] **Cons:** [List] ### Option B: [Name] [Same format] ## Trade-off Analysis [Key trade-offs between options with clear reasoning] ## Consequences - [What becomes easier] - [What becomes harder] - [What we'll need to revisit] ## Action Items 1. [ ] [Implementation step] 2. [ ] [Follow-up] ``` ## If Connectors Available If **~~knowledge base** is connected: - Search for prior ADRs and design docs - Find relevant technical context If **~~project tracker** is connected: - Link to related epics and tickets - Create implementation tasks ## Tips 1. **State constraints upfront** — "We need to ship in 2 weeks" or "Must handle 10K rps" shapes the answer. 2. **Name your options** — Even if you're leaning one way, I'll give a more balanced analysis with explicit alternatives. 3. **Include non-functional requirements** — Latency, cost, team expertise, and maintenance burden matter as much as features.
