Use this skill after $meshy-blender-spritesheet, $meshy-api, or any other art workflow has produced source art that should become a Factorio/ESIR asset draft.

Do not leave the only copy of a reusable generator script, hand-written note, or prompt there; promote durable sources to .codex/esir/asset-generators/ or .codex/esir/art-prompts/.exotic-space-industries-remembrance/graphics/ or edit prototypes unless the user explicitly asks for that follow-up. Promotion remains dry-run unless --execute is passed.icons entries so the game composites them. A baked composite may be emitted as a preview artifact, but it must not be the only shipped asset unless the user explicitly asks for a flattened icon.alpha_bounds, treat non-empty warnings or margins below the requested min_alpha_margin as a rerender cue.render-bundle manifests with base, shadow, light/glow, and mask passes. Treat single-sheet entity/machine exports without a shadow or preset-equivalent manifest as draft-only unless the user explicitly requested no shadow or non-preset output.object_mask_0.png as unclassified until review marks it as a runtime-tint mask, manual post-processing source, or unused evidence. The exporter stages masks; it does not mean the prototype is colorable until the Lua layer explicitly includes flags = {"mask"} and apply_runtime_tint = true.ei- from staged filename roots and final graphics directories. Keep ei-* only in prototype metadata, snippet hints, and promotion --prototype-name when the prototype uses that internal name.$esir-item-icon-prep behavior instead of hand-building mip strips.entity: one-frame or directional entity sheets. Factorio-bound entities should include a separate shadow sheet unless explicitly no-shadow.machine: base machine sheet plus shadow, with optional working_visualisations animation sheet and matching working shadow.icon: source art to a staged 128/64/32 Factorio item icon strip.render-bundle: staged output from the local Factorio rendering preset, such as Render.zip, an extracted Render/.Sheets folder, or raw Render/Object/*.png frame folders, preserving base, shadow, mask, light, glare, and water-reflection sheets. Large exports can emit Factorio stripes; mask sheets still need manual classification before prototype wiring.promote: dry-run or explicitly execute narrow asset copies and marker-delimited prototype patching from a staged manifest, with optional asset-count and prototype-identity guards.gallery: static visual approval HTML over staged manifests and preview/source PNGs.Read references/factorio-asset-options.md when choosing fields, scale, shifts, or snippet shape.

Each run writes staged files only:
<asset>.factorio-asset-manifest.json<asset>.prototype-snippet.luaThese staged files remain generated review artifacts under ignored output/. Commit final approved PNGs only after promotion into the mod graphics packs, and commit reproducible procedural source scripts under .codex/esir/asset-generators/ instead of under an output source/ folder.
The Lua snippet assumes the staged PNGs will eventually be copied into the graphics folder matching the selected path variable, such as ei_graphics_entity_path or ei_graphics_item_path. Icon snippets are prototype-table field fragments and keep trailing commas for pasteability inside an item prototype. --snippet-template, --target-prototype-type, --target-prototype-name, and --target-field add prototype-aware comments and manifest metadata for safer promotion planning; they do not copy or patch anything. Preset mask sheets remain staged evidence unless the snippet or later prototype patch explicitly wires a mask layer with flags = {"mask"} and apply_runtime_tint = true.
promote prints the exact copy and patch plan by default. It only copies PNGs or edits Lua when --execute is present, and prototype patching requires explicit -- ESIR_ASSET_PROMOTE_START <prototype-name> <field> / -- ESIR_ASSET_PROMOTE_END <prototype-name> <field> markers. Use --prototype-integration data-raw-assignment when a marker block should become a guarded data.raw["type"]["name"].field = ... assignment instead of a raw snippet fragment.
ESIR-first repo-local development surface for Exotic Space Industries: Remembrance. Use when Codex should work faster inside this workspace by relying on checked-in manifests, the ESIR wrapper command, Factorio QC delegation, Mod Portal scouting, save catalog resolution, Lua/runtime/prototype helper routing, Meshy/Blender asset pipeline routing, Factorio asset export, item icon prep, recipe icon style audits, art/browser session handoff, cache diffing, packaging, or ESIR-specific runtime/prototype maps.
Use when Codex should create, inspect, or render Blender procedural animations for non-human assets, ESIR machines, crystals, gates, orbitals, props, Meshy GLBs, animation spritesheets, or Factorio-ready transparent frame sheets.
Use when Codex should orchestrate a full ESIR asset pipeline from Meshy prompts or existing models through Blender static/procedural rendering, Factorio-style shadows, staged Factorio export, previews, QA, manifests, and reproducible asset dossiers.
Use when ESIR item art needs to be turned into a transparent Factorio item icon strip, especially when source art has a baked light checkerboard or white background and must end up as a `128/64/32` mipmapped item icon under `exotic-space-industries-remembrance/graphics/items/`.
Prefer the shared `ei_lib` helper surface in `exotic-space-industries-remembrance/lib/lib.lua` before creating new Lua local functions. Use when Codex edits ESIR runtime, data-stage, prototype, migration, or support Lua files and might add utility helpers, table or string helpers, recipe or technology mutation helpers, notification helpers, color or formatting helpers, wrappers around `data.raw`, prototype `custom_tooltip_fields`, or runtime `LuaEntity.custom_status` combat readouts such as DPS/status rows for weapons, turrets, or vehicles. For runtime queue, delayed-bucket, telemetry-gate, counter, or status-snapshot plumbing, prefer `exotic-space-industries-remembrance/lib/runtime-scheduler.lua` instead. Inspect `ei_lib` first when the helper is general utility; if it almost fits, extend or harden the shared function instead of inventing a one-off local helper.
Use when Codex should render or wire ESIR Factorio train and rolling-stock body sprites, especially elevated-rail sloped train sprites, rolling_stock_template.blend, susanne_0.0.1.zip precedent, Spritter spritesheet packing, normal/sloped frame contracts, or prototype RotatedSprite metadata for locomotives, cargo wagons, fluid wagons, or train bodies.
