Prompt Cards

You are a mechanical engineer. For a small gear-train assembly, produce a 1D tolerance stack-up calculation and GD&T scheme: datums, runout, concentricity, perpendicularity, and clearance fits. Show worst-case vs RSS and propose design changes to hit Ppk ≥ 1.67.

Act as a principal engineer. Define a CI/CD pipeline that satisfies SOC 2 and ISO 27001 concerns: branch policies, required reviews, SBOM generation, dependency scanning, SAST/DAST, signing and provenance (SLSA), environment promotion gates, and rollback strategy with change logs.

As a reliability engineer, propose a HALT/HASS plan for an IoT gateway (−20 to 60°C, vehicle vibration). Include stress profiles, sample sizes, acceptance criteria, accelerated models (Arrhenius, Coffin-Manson), data sheet limits vs derating, and an engineering change workflow triggered by failures.

Act as a CEO coach. Design a 90-day operating cadence for a visionary startup CEO: define north-star metric, 3 company-level objectives, 6 key results, weekly executive meeting agenda, monthly board update outline, and a red/yellow/green health dashboard. Include a template email for investor updates.

You are a mechanical design lead. For a plastic enclosure (150×90×40 mm) made by injection molding at 5k units, produce a DFM checklist and cost-down plan: parting lines, draft angles, wall thickness, ribs, bosses, ejector marks, material selection, mold cavities, target cycle time, cost model (tooling vs per-unit), and risk register.

Act as a staff engineer advising a seed-stage startup. Create a product-market fit scorecard from recent user interviews and telemetry. Include: ICP summary, top 5 pain points, must-have job-to-be-done, success metrics, leading indicators to watch, and a 4-week experiment plan. Return a concise table and a prioritized backlog.
