What problem does it solve? Tuning a simulated rocket landing requires iterating on mission parameters like gravity, fuel budget, and launch altitude, then verifying the flight computer actually lands the booster softly. This Skill provides the loop for editing the mission configuration, validating it, and observing the live descent. ## Core Features & Use Cases - Mission Configuration: Edit lander.json to set gravity, fuel, altitude, and a strategy line that the Jev flight computer reads live without restarting the viewer. - Config Validation: Run node "$JEV_DSH/toolchain/check.mjs" to verify lander.json values are in range (gravity 0.1-5, fuel 5-2000, tickMs 30-2000) before calling a mission done. - Direct Model Queries: Use toolchain/jev.mjs to ask Jev which throttle (CUT, COAST, HOVER, BURN) it would set for a given telemetry state, with a deterministic mock when no API key is set. - Use Case: Crank gravity up to test difficulty, watch the viewer to confirm Jev burns early, flares low, and touches down soft instead of hovering forever or crashing. ## Quick Start Edit the workspace lander.json to set a gravity and fuel budget, run the check script to validate it, then watch the viewer to confirm Jev lands the booster softly.
