Clear all files in a preset slot (preset.json, main.lua, devices.json, ...).
AI agents call clear_preset_slot to permanently remove resources in Electra One — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs irreversible deletion of data. Even though the blast radius is limited to a single preset slot rather than system-wide, the permanent removal of all preset files (configuration, scripts, device mappings) makes this Destructive rather than Write. A misconfigured AI agent could delete user presets unintentionally.
From the tool's definition Tool description states 'Clear all files in a preset slot' - this irreversibly deletes multiple files (preset.json, main.lua, devices.json) from a preset configuration without undo capability.
