What it does
Catalog is an agent skill from LiberatedPixelCup/Universal-LPC-Spritesheet-Character-Generator. Thread CatalogReader and State through Mithril attrs, never a hidden global. Handle Result/LoadError, seed test catalogs, and keep URL hashes stable. Use when adding or editing a component, a browser spec, or sources/state/ code, or when the user mentions catalog, state, hash, or aliases.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Character Generator based on Universal-LPC-Spritesheet. The licence is GPL-3.0.
When your agent uses it
- Editing a component
- Sources/state/ code
- The user mentions catalog
Example prompts
- “/catalog”
What it can do on your machine
Read from SKILL.md and the folder at commit 58ce1aa. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Catalog loads about 1.3k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 537 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Thread CatalogReader and State through Mithril attrs, never a hidden global. Handle Result/LoadError, seed test catalogs, and keep URL hashes stable. Use when adding or editing a component, a browser spec, or sources/state/ code, or when the user mentions catalog, state, hash, or aliases.
Catalog, state, and URL hash
Production
Thread catalog: CatalogReader and state: State from bootstrap to a UI
composition boundary. Prefer passing a narrow model below that boundary when
one exists; CurrentSelections is the first example. Build those models in
main.ts, then have components forward or consume their assigned slices rather
than constructing dependencies themselves. Do not read a hidden global. Views
must not receive CatalogWriter (register*Metadata,
loadCatalogFromFixtures).
Getters return Result<T, LoadError> (neverthrow). LoadError is
{ kind: "loading"; chunk } or { kind: "not-found"; id }.
- Views:
renderResultfromsources/utils/render-result.ts - Elsewhere:
.match/.unwrapOr/if (r.isErr())
Use typed getters (getItemLite, getItemLayers, getCategoryTree, …).
Readiness is staged: isIndexReady(), isLiteReady(), isCreditsReady(),
isPaletteReady(), isLayersReady(), plus catalog.ready.on*. UI already
branches on these (e.g. preview-canvas-loading.ts).
Only sources/main.ts calls
configureStateCatalog. That binds the catalog for sources/state/ so those
modules do not take a catalog argument on every call. It is not a hidden
global for UI — components still receive catalog and state as attrs.
createCatalog() returns separate { reader, writer } runtime objects backed
by the same private stores. sources/install-item-metadata.ts
starts registration with the writer and returns only the reader to production
bootstrap.
Importing generated metadata
Source code imports the five chunks as ../<name>-metadata.js, not as a
dist/ path. itemMetadataResolveAliases() in
vite/wiring.ts installs a resolve.alias regex
that rewrites any specifier ending in a metadata basename to dist/. So
install-item-metadata.ts and
browser-catalog-fixture.js both
write ../index-metadata.js and get dist/index-metadata.js. Copy the
existing specifier shape; do not "fix" it to a real path, and do not expect the
file to exist next to the importer. If it fails to resolve, dist/ was never
built — run npm run dev or npm run build. Stale .cache/ or a missing
dist/ after a definition change:
generated-metadata.

Tests
Destructure { reader, writer } = createCatalog() and create a fresh
createState(). Never use the production reader or bootstrap state instance.
Create a new catalog rather than re-seeding: loadCatalogFromFixtures and
register*Metadata overwrite the stores but cannot move a resolved stage
back to unresolved. A spec that re-seeds expecting a fresh "loading"
catalog will silently see resolved stages instead.
Call configureStateCatalog(catalog) when the spec exercises sources/state/
effects. Override individual effects with setStateDeps and restore them with
resetStateDeps.
seedCatalog— pass the writer to seed explicit fixtures; pass the paired reader to consumersseedCatalogWithGeneratedContext— keeps generated palette/alias/tree/index context; needs generated metadata, so runnpm run devornpm run buildfirstregister*Metadata— one readiness stage
A new spec has to actually hit the lines it covers: coverage.
Emitted vs expanded ItemLite
dist/item-metadata.js may intern variant strings and recolor palette maps.
registerItemMetadata / registerIndexMetadata expand those into the runtime
shapes getters return. Do not read v / r / p off getItemLite.
| Field | Emitted (interned) | Expanded (runtime ItemLite) |
|---|---|---|
variants | omitted; v indexes variantArrays | string[] |
recolors[0].variants | omitted; r indexes recolorVariantArrays | string[] |
recolors[].palettes | omitted; p indexes paletteArrays | PaletteMap |
| licenses / tags / priority | not on lite (credits chunk / sheet JSON / generator sort) | not on lite |
MetadataIndexes may include variantArrays, recolorVariantArrays, and
paletteArrays. Expansion keeps those tables on the index store. Palette
restore (hasInternedPalettes) does not require v / r. Until the index
chunk arrives, getPaletteOptions treats missing palettes as {}.
URL hash
Shape: type_name=Item_variant (e.g. expression=Neutral_light). Old hashes
must keep working. Put aliases on the destination definition. Do not
rewrite or delete old hash keys. Discuss renames in an issue first.
Details: Catalog and state, URL hash.
