New template for Sim Studio — an open-source AI workflow builder for designing, simulating, and testing multi-agent pipelines with real-time collaboration.
I have tested the template in my instance, so the maintainers don't spend time trying to figure out what's wrong.
I have added tests that demonstrate that my correction works or that my new feature works.

Services included:
simstudio — main app (port 3000)
realtime — WebSocket collaboration server (port 3002)
migrations — one-shot init container (runs DB migrations)
db — pgvector/pgvector:pg17 (Postgres with vector extension)
All secrets (BETTER_AUTH_SECRET, ENCRYPTION_KEY, INTERNAL_API_SECRET, POSTGRES_PASSWORD) are auto-generated by Dokploy on deploy.
Greptile Summary
This PR adds a Sim Studio template — an open-source AI workflow builder with multi-agent support — comprising four services (simstudio, realtime, migrations, db). The overall architecture is solid: proper depends_on conditions, healthchecks, a one-shot migration container, and auto-generated secrets via template.toml. The apparent Strapi removal in meta.json is benign — it deduplicates an entry that already existed twice in the base branch.
However, two mandatory AGENTS.md conventions are violated that must be resolved before merging:
ports instead of expose: Both simstudio (3000) and realtime (3002) use ports: — AGENTS.md explicitly forbids this and requires expose: so Dokploy's networking layer handles routing.
Missing version: "3.8": The top-level Compose version declaration is absent; all blueprints are required to include it.
Unpinned :latest image tags (P2): All three ghcr.io/simstudioai/* images float on :latest, against the security guideline to pin to specific versions. The meta.json"version": "latest" should be updated to match once a tag is pinned.
Confidence Score: 2/5
Not safe to merge — two mandatory AGENTS.md conventions are violated (ports vs expose, missing version: "3.8") that will cause deployment issues on Dokploy.
The template structure and secret management are well done, but the two hard requirements from AGENTS.md (expose instead of ports, version: "3.8") are both missing. These are flagged as CRITICAL in the guide and will prevent the template from working correctly in Dokploy's networking model. Once those two fixes are applied (plus optionally pinning image versions), the PR should be ready to merge.
blueprints/simstudio/docker-compose.yml needs the ports → expose change and the version: "3.8" header added.

<h3>Greptile Summary</h3>
This PR adds a Sim Studio template — an open-source AI workflow builder with multi-agent support — comprising four services (`simstudio`, `realtime`, `migrations`, `db`). The overall architecture is solid: proper `depends_on` conditions, healthchecks, a one-shot migration container, and auto-generated secrets via `template.toml`. The apparent Strapi removal in `meta.json` is benign — it deduplicates an entry that already existed twice in the base branch.
However, two **mandatory AGENTS.md conventions** are violated that must be resolved before merging:
- **`ports` instead of `expose`**: Both `simstudio` (3000) and `realtime` (3002) use `ports:` — AGENTS.md explicitly forbids this and requires `expose:` so Dokploy's networking layer handles routing.
- **Missing `version: "3.8"`**: The top-level Compose version declaration is absent; all blueprints are required to include it.
- **Unpinned `:latest` image tags** (P2): All three `ghcr.io/simstudioai/*` images float on `:latest`, against the security guideline to pin to specific versions. The `meta.json` `"version": "latest"` should be updated to match once a tag is pinned.
<h3>Confidence Score: 2/5</h3>
- Not safe to merge — two mandatory AGENTS.md conventions are violated (`ports` vs `expose`, missing `version: "3.8"`) that will cause deployment issues on Dokploy.
