Tool

Does

findRecords

Search the active load order by name or editor ID; resolve FormIDs to names and back

readRecord

One record as project text — the winning version, one plugin's, or every version side by side

Tool

Does

newProject

Start a new mod

addPatch

Copy existing records into a patch as overrides, from their winning version, to change them without touching the original mod

editRecord

Change a record file's fields by their paths, with no old text to match — and build again in the same call

moveRecord, deleteRecord

Put a record file where the build reads it, or remove one the mod no longer needs

buildProject

Text → plugin: assigns FormIDs to new records, checks every reference, compiles Papyrus scripts, and lists what the plugin holds — and warns of what would go wrong in game: an armor no one can wear, a missing mesh, an effect that does nothing, a chest under the floor

deployProject

Build → mod manager: mod folder, enabled, plugin at the end of the load order

pullProject

Changes made in the Creation Kit or xEdit → back into the text

Tool

Does

exportCell

A cell → Blender: its objects with their meshes and textures, outdoors its ground, and its navmesh, saved as a .blend with the scripts that place them (PyNifly add-on)

importCell

Blender → the project: objects moved, copied or deleted as the mod's own references, the ground sculpted, the navmesh edited

editTerrain

The ground outdoors flattened (a plot for a house), raised, lowered or smoothed in a circle, blended into the land around

generateNavmesh

A cell's navmesh, made from the collision of what stands in it, indoors and outdoors: load doors linked, edges linked with the cells beside it

newWorldspace

A land of the mod's own, apart from Skyrim: flat or from a heightmap image, with water and Skyrim's weather, and a start cell to coc to

newCell

A room of the mod's own, made like a room of the game — its walls, lights and furniture — with a pair of load doors to the cell the player comes from

Tool

Does

findConflicts

Which plugin's changes to a record are lost to another's, change by change, and which mods' files hide each other's; addPatch with merge then makes a patch that keeps every plugin's changes

sortPlugins

The load order sorted by LOOT's own library and masterlist, with LOOT's messages: a preview first, applied on the user's word

movePlugin

One plugin moved in the load order, on the user's word, where the game can load it

setModPriority

One mod moved in the mod order, on the user's word, so its loose files win or lose

Tool

Does

searchNexus

Find Skyrim SE mods on Nexus Mods by name, or list the most endorsed, downloaded or updated

readNexusMod

One Nexus mod page: description, requirements (SKSE, other mods, DLC), the files it offers

downloadNexusFile

A file of a Nexus mod into the instance's downloads folder — with a premium account's API key

installMod

A downloaded file → a mod: unpacked, its FOMOD installer answered, enabled, its plugins active

enableMod, disableMod

A mod enabled or disabled, on the user's word — and which plugins now miss a master

listMods

The mods installed, in priority order: enabled or not, their plugins, their Nexus record, whether they carry SKSE plugins

Tool

Does

readCrashLog

Why the game crashed, from Crash Logger SSE's log: known crashes with their fixes, and the mods behind what the log names

readPapyrusLog

What the game's scripts did wrong, from the Papyrus log: problems grouped and counted with their fixes, each script by its mod, script lag, a save's leftovers of removed mods

checkGameVersion

Whether SKSE, Address Library and each SKSE plugin fit the game version

editIni

Settings of Skyrim.ini, SkyrimPrefs.ini or SkyrimCustom.ini, on the user's word
