MANUAL TRIGGER ONLY: invoke only when user types /office-hours. YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively suggest when the user describes a new product idea or is exploring whether something is worth building — before any code is written.

System-design thinking before any doc or code: goals/non-goals, back-of-envelope numbers, components and contracts, failure modes, operability, security, trade-offs. Use for "design this system", "architecture for X", "trade-offs for X", "how should we architect", "API design", "data model for", "service boundaries", or before an ADR. Hands off to /ship:write-docs to record the decision. Not implementation planning (/ship:design — that turns a decided design into stories).

Create or update structured docs under docs/ with frontmatter, numbering, lifecycle status, and index regeneration — guides, references, troubleshooting, design docs and ADRs. Use for "write a doc", "document this", "create a guide", "write an ADR", "update the docs". For the system-design thinking itself (architecture, trade-offs, failure modes) use /ship:arch-design first — it hands back here to record the decision.
