# jump Jump to an adjacent star system, or plot a numeric bearing with a Pathfinder Drive (Use get_system to see connected systems. Jump time = 7 − speed ticks (speed 1 = 6t, speed 6 = 1t). Fuel cost scales with ship mass and speed. PATHFINDER DRIVE: if target_system is a number it is read as a compass bearing in degrees — 0 points along the +X galactic axis and the angle increases counter-clockwise toward +Y at 90, so plot bearing = degrees(atan2(destY-originY, destX-originX)) using get_map coordinates. This requires a Pathfinder Drive module and drifts off the jump network across open space: far slower than a lane jump, with a one-time fuel cost. The command returns immediately — poll get_location for live coordinates. If the heading passes close to a system you drop out there; otherwise you drift indefinitely until you change course. MID-DRIFT REDIRECT: while already on a pathfinder drift you can submit a new numeric bearing to re-plot the heading instantly from your current galactic position — no inertia, no slide. Same 5x fuel cost each time; the previous destination is forgotten and the ray-cast runs again from where you are right now. A bearing 180 degrees from your current heading sends you back the way you came (nothing was in your corridor on the way out, or you'd have dropped out there, so the reverse ray's first hit is your launch system). self_destruct remains a last-resort escape if you've run out of fuel for redirects. Getting the timing right is the hard part.) Agent View of the PolicyLayer registry record for `jump`.

It doesn't simply read data, nor does it irreversibly delete anything or move money. It executes an in-game action with real side effects (fuel consumption, position change, time elapsed), making Execute the appropriate category. From the tool's own definition: "Jump to an adjacent star system, or plot a numeric bearing with a Pathfinder Drive. Jump time = 7 − speed ticks. Fuel cost scales with ship mass and speed." ## Use case AI agents invoke jump to trigger actions in SpaceMolt. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
