Generate ecosystem-specific .dockerignore files to reduce build context size and prevent secret leaks. Use when no .dockerignore exists, when the build context is large, or when secrets may be leaking into images.
Domain setup for applications. Preferred path is passing domains at creation time via createProject. Falls back to add_application_domain for post-creation attachment or custom domains.
Diagnose domain resolution, TLS certificate provisioning, and reverse proxy routing issues. Use when a domain is not resolving, TLS certificates fail, proxy returns 502/503/504, or custom domains are stuck in pending status.
Build and deploy .NET applications — ASP.NET Core, version detection, self-contained builds, and Dockerfile patterns. Use when deploying a .NET or C# project, or when a .csproj file is detected.
Build and deploy Elixir and Phoenix applications — version detection, mix releases, and Dockerfile patterns. Use when deploying an Elixir or Phoenix project, or when mix.exs is detected.
Detect required environment variables from source code, config files, and .env examples. Use when preparing for deployment, checking for missing env vars, or when the user asks about required environment configuration.
Diagnose deployment failures, container crashes, and networking issues using structured pattern matching on logs and container state. Use when a deployment fails, a container crashes or exits unexpectedly, or the app is unreachable after deployment.
Build and deploy Gleam applications — erlang-shipment, version detection, and Dockerfile patterns. Use when deploying a Gleam project, or when gleam.toml is detected.
Build and deploy Java applications — Maven, Gradle, Spring Boot, version detection, and Dockerfile patterns. Use when deploying a Java project, or when pom.xml or build.gradle is detected.
