This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Overview

MetaAppStore is the CasaOS / Yundera 3rd-party app store for the MetaMesh application family only. It was split out of Worph/AppStore — the general-purpose fork — so the MetaMesh apps release on their own cadence. Apps that are not MetaMesh (Jellyfin, Nextcloud, MetaMCP — third-party metatool-ai software despite the name, …) stay in Worph/AppStore and must not be added here.

⚠ Asset URLs point at this repo on Gitea. Everything in this repo must reference https://gitea-watch.nsl.sh/metastar/MetaAppStore/raw/branch/main/Apps/{AppName}/. The GitHub repos are gone, so every jsDelivr cdn.jsdelivr.net/gh/Worph/... URL (this repo's old ones, or .../gh/Worph/AppStore@main/... in a file copied over from Worph/AppStore) 404s and the icon silently disappears from the store listing. Grep after any import:

grep -rn 'cdn.jsdelivr.net/gh/Worph' Apps/   # must be empty

Structure

Apps/{AppName}/ — one dir per app:
- docker-compose.yml — compose + x-casaos metadata (the store entry)
- icon.png, thumbnail.png, screenshot-{1,2,3}.png
- optional rationale.md, README.md, pre-install/
category-list.json — Media (every MetaFeeder and client app) and Developer (the MetaPlugin family)
recommend-list.json, featured-apps.json — store front placement
psd-source/meta-icons-v2/ — procedural icon generator for the family (gen_mesh.py mesh sphere + meta_icons.py per-app badge); see its README

Conventions

Storage: /DATA/AppData/{appname}/; media under /DATA/Media/, /DATA/Downloads/
Networking: expose, not ports; main services join the external pcs network for Caddy routing. Three caddy labels per public service: caddy_0 gateway domain (appname-${APP_DOMAIN}, gateway_tls import), caddy_1 <app>-${APP_PUBLIC_IP_DASH}.${APP_IP_ZONE} (the IP zone, gateway_tls import), caddy_2 sslip.io (Let's Encrypt, no import)
store_app_id is the lowercased app name (MetaFeederTMDB → metafeedertmdb)
Images: pulled from IPCR on watch.nsl.sh, ipcr-watch.nsl.sh/ipns/metadec.eth/metadec.eth/<image>:<version>, pinned to explicit versions (built by each repo's .gitea/workflows/ on gitea-watch.nsl.sh/metastar on v* tags; ghcr.io/worph is no longer published). The Yundera perimeter images (nginx-hash-lock, appshield) stay on ghcr.io/yundera
Install order: MetaCore first — every other app depends on it
Multi-language: descriptions/taglines carry en_us, fr_fr, es_es, zh_cn, ko_kr, de_de

The three app families

Family	What it is	Shape	Category
`Meta*`	The services — Core, Sort, Fuse, Share, Gateway, Watch, Read, Stremio	backend + AppShield gate, real dashboard	Media
`MetaFeeder<Provider>`	One upstream, one app (see the provider-naming rule below)	`<sid>-feeder` + AppShield gate, `index: /config`	Media
`MetaPlugin<Name>`	One `metamesh-plugin-*` enrichment worker, standalone	`<sid>-plugin` + AppShield gate, `index: /manifest`	Developer

MetaFeeder apps are named by PROVIDER, one provider per app — role/bundle names (Card, Indexer, Comic, Book, Common, Paper, Subtitle) are retired. Gateway feeder keys follow <provider>-feeder; the feeder's upstream_id() in its crate is the authority for the provider spelling.

MetaPlugin: what these apps can and cannot do

A metamesh-plugin-* image is a headless worker speaking four verbs — /manifest, /health, /configure, /process. It has no UI, so the tile opens /manifest, and it holds no credentials: the caller POSTs /configure with its own TMDB token / OpenSubtitles account before use. Two consumers sharing one instance are last-writer-wins on that config.

⚠ MetaSort cannot consume these apps. ContainerPluginConfig (packages/meta-sort/.../container-plugins/types.ts) takes an image: and MetaSort spawns the container itself; there is no url: field. Until one exists, installing a MetaPlugin app does not add that plugin to MetaSort.

⚠ Only three plugins have a consumer that takes a URL today — the feeder SDK's sidecar slots, FILENAME_PARSER_URL, TMDB_PLUGIN_URL and OPENSUBTITLES_PLUGIN_URL (meta-feeder-sdk/src/enrich.rs). The other nine MetaPlugin listings are packaging ahead of the consumer, and each one says so in its own description and tips — keep that wording honest if the situation changes.

⚠ MetaPluginFilenameParser cannot be shared between a feeder and MetaSort. EMIT_TITLE_TAGS is process-level and the two want opposite values (a feeder has no real file and wants title guesses; MetaSort probes the real stream and must not have them). Install a second copy rather than flipping it.

Note the SDK derives a sidecar URL from the feeder's own hostname when the variable is unset (derive_sidecar_url), which is why pointing a feeder at a shared MetaPlugin app requires setting the variable explicitly.

Cross-repo notes

Apps here are the deployable face of the services in MetaMesh/meta-root-v2; this repo is vendored there as packages/MetaAppStore. A compose change made directly on a box (e.g. holyhorse, watch.nsl.sh) is overwritten by a store reinstall — port anything load-bearing back here.
Non-Meta companions live in Worph/AppStore: Suwayomi (chapter tier for MetaFeederSuwayomi) and SegmentPlayer. Cross-references between the two stores are prose-only; don't add hard dependencies.

Validation

docker compose -f Apps/{AppName}/docker-compose.yml config   # compose validity
jq . category-list.json recommend-list.json featured-apps.json
grep -rn 'cdn.jsdelivr.net/gh/Worph' Apps/                     # must be empty
