# SIESTA MD (Subskill)

## Scope

This skill prepares MD tasks only.

It should generate:

- MD-capable SIESTA input
- ensemble/integrator/thermostat controls
- trajectory/output policy

It should not submit or execute jobs.

## Must provide

- structure input
- basis/pseudopotential set choice
- timestep and number of steps
- ensemble intent (`NVE`/`NVT`/`NPT`)
- temperature/pressure control policy

## Usually should be explicit

- initial velocity policy
- output stride for energies/trajectory
- charge/spin and SCF policy

## Expected output

1. MD-task input layout
1. MD control summary and assumptions
1. unresolved choices for confirmation
1. handoff note to `dpdisp-submit` if execution is requested
