Edit Catalog Agent Skill

Edit the Catalog

Read CONTEXT.md for App, Recipe and Catalog, and docs/agents/generated-data.md for what is derived from what and which counts are hand-kept. For a new App, copy the shape of the last one: git show --stat ca78641b (Cleanuparr).

Pick the branch, then run its steps in order:

• New App: steps 1 to 8.
• Change an App: steps 1, 2, 6 and 8, plus 5 when its repository or icon changes. Edit the App's package under internal/apps/; its directory is the id without hyphens or a shorter name (paperless-ngx lives in paperlessngx), so find it with grep -rl 'ID: "<id>"' internal/apps.
• Change a Recipe: edit registerRecipes in internal/catalog/batch_recipes.go, then steps 6, 7 and 8.
• Hide or unhide an App: edit unavailable in internal/catalog/catalog.go with the reason and the issue that tracks the way back, then steps 6, 7 and 8.

1. Resolve upstream facts

Take the image, tag, ports, volumes and env from the project's own docs or registry page, not from memory or an aggregator.

Done: each fact has a source URL you can put in the PR body.

2. Find an existing home

Search internal/apps/, internal/catalog/, dcm/src/tools/ and ALIASES in dcm/src/lib/selfhost.ts for the product under every spelling (actualbudget against actual-budget).

Done: no hit, so you add one App, or you edit the existing App and add none. Every Container for the same product in dcm/src/tools has the App's id or an ALIASES key for it; otherwise DCM lists the product twice. Add the missing ALIASES entry in the same change.

3. Write the App

Add internal/apps/<name>/<name>.go and its test, where <name> is the id without hyphens, and docs/catalog/traps/<id>.md, which keeps the hyphens. Info().ID is the id itself. The description is at most 100 characters in plain words (internal/catalog/descriptions_test.go enforces it). Extra services are named <id>-.... Setup follows internal/helpers/ and the Protected invariants in AGENTS.md: Secrets stay in secrets.env.

Done: go test ./internal/apps/<name>/ passes.

4. Register

Add the import and <name>.App{} to a batch_*.go in internal/catalog/, in alphabetical order. generated.go is generated; leave it.

Done: go test ./internal/catalog/ passes. A parity_test.go failure on a ported App means a legacy fact changed: add a deviations entry with the reason; leave legacy-facts.json as it is.

5. Declare site metadata

In tools/sitegen/icons.go add the id to icons with its Dashboard Icons path ("" for none); sitegen's error names the entry when one is missing. In tools/sitegen/stars.go add the upstream repository to repos. Nothing fails when repos lacks the App; its star count never appears.

Done: grep -n "<id>" tools/sitegen/icons.go tools/sitegen/stars.go prints a line from each file.

6. Regenerate

go run ./tools/sitegen

Add StandaloneGuide to the App only when its standalone Compose needs a sentence of guidance; sitegen fails when the guide names a variable or folder the converted Compose lacks.

Done: a second run changes nothing, and git status shows only your files plus site/src/data/catalog.json and dcm/src/data/selfhost.json.

7. Fix the counts

Follow the "App counts" table in docs/agents/generated-data.md: README, e2e/acceptance.md, the fixture and inventory.json, and the TUI goldens (go test ./internal/tui -update, then read the diff). The counts differ on purpose, so move each by the amount that table gives.

Done: the jq and grep commands in that page show the new numbers, and go test ./e2e/ ./internal/tui passes.

8. Gate

Run the Go gate from AGENTS.md, then the web gate: generated data changed. Never run Docker, e2e or the installer.

Done: both exit 0 and git status shows only files that belong to this change.
