Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloudron-app-publishing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cloudron App Publishing

Distribute Cloudron apps independently using a CloudronVersions.json version catalog. Users add the file's URL in their dashboard or install via cloudron install --versions-url <url>.

Quick Reference

  • Docs: docs.cloudron.io/packaging/publishing
  • Upstream skill: git.cloudron.io/docs/skills (cloudron-app-publishing)
  • Prerequisite: Each version needs a registry-hosted image, normally built with cloudron builder login → cloudron builder build; on-server builds cannot be published
  • Last upstream review: 74e455bd03f5; adopted registry builder and explicit version-image selection guidance
  • Key file: CloudronVersions.json — version catalog hosted at a public URL
  • Listing: Cloudron Community Apps accepts a public versions URL after the catalog contains a tested release; listing is optional
  • Forum: announce published community packages in Community Apps (220); ask packaging questions in App Packaging & Development (96)

Workflow

Keep these states distinct: upstream detected (a monitor finding), package prepared (manifest and changelog updated), image build verified (immutable Docker sources resolve and a no-push build succeeds), and catalog published (a reviewed image is present in CloudronVersions.json). Detection does not authorize any later state.

cloudron versions init  # creates CloudronVersions.json + DESCRIPTION.md, CHANGELOG, POSTINSTALL.md (edit all placeholders)
cloudron builder login  # authenticate with the Container registry app
cloudron builder build  # build and push image; remembers the repository
cloudron versions add --last-build --state testing  # record the last builder image without exposing it as stable
cloudron versions update --version=1.0.0 --state=published
# host CloudronVersions.json at a public URL

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
