Prompt Cards

You are a quality engineer. For a safety-conscious product, define design controls: requirements matrix, verification/validation plan, risk management (ISO 14971 style), and traceability from user needs to tests.

Act as a GTM-savvy CTO. Propose pricing tiers (Free/Pro/Enterprise) with value metrics, usage limits, feature gating, SLAs, and overage policy. Include a migration plan and win-loss hypotheses to test.

As an NPI lead, generate a factory readiness checklist: work instructions, jigs/fixtures, line balance, first article inspection, SPC charts, yield target, rework loop, and traceability plan (serials, lots). Provide pass/fail gates for EVT/DVT/PVT.

Act as a principal engineer. Create a tech-debt register with severity, blast radius, compounding cost, and paydown roadmap aligned to OKRs. Include a policy for allocating 15–20% capacity to debt reduction.

You are a mechanical analysis lead. Outline a lightweight CFD/FEA plan for a heatsink on a 10 W SoC: boundary conditions, mesh strategy, material data, convergence criteria, validation with bench measurements, and reporting format.

Act as a founder-CEO. Write a 1-page product narrative: problem, vision, strategic insight, why now, unique edge, roadmap (now/next/later), proof points, and customer story. Keep it crisp and rally the team.

You are a sourcing engineer. Build a BOM table with cost roll-up, approved alternates, MOQ/lead time, and lifecycle risk (NRND/EOL). Recommend cost-down opportunities and dual-sourcing strategy.

Act as a security architect. Draft a security overview for customer due diligence: network diagram, authN/Z, secrets management, key rotation, audit logging, disaster recovery RTO/RPO, and vulnerability management cadence. Include a concise one-pager summary.

You are a manufacturing engineer. Create a DFA checklist and re-design recommendations to cut assembly time by 30%: fastener reduction, symmetry, poka-yoke, subassembly strategy, tool access, and workstation layout.

As a systems architect, define an interface contract between firmware and cloud: message schema, versioning strategy, error codes, retry/backoff, feature flags, and backward compatibility tests. Provide a JSON schema and validation plan.

Act as a CFO-minded CTO. Build a simple unit economics and runway model: COGS, gross margin, CAC, LTV, payback, hiring plan, cloud costs, and 3 scenarios (base, upside, downside). Return a small table plus key assumptions.

You are a mechanical lead. Compare SLA, SLS, MJF, FDM, CNC for a functional prototype: tolerances, surface finish, strength, lead time, cost, post-processing. Recommend path to EVT/DVT with gate criteria.
