Build a Go HTTP CQRS application with Arc.Go commands, read-model queries, validation, identity and explicit hosting lifecycle. Use for the tagged root module and handwritten typed adapters. Do not use for Chronicle-only clients, C# or JVM Arc, or unpublished Go integration and generator modules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

Companion guidance targets > Chronicle.Go **v0.9.1** and Fundamentals.Go **v0.3.2**. Minor releases may break APIs. **Only `github.com/cratis/arc.go`, the root module, is tagged.** Chronicle and MongoDB integrations, `arc-gen`, `arc-vet` and framework-host recipes are separate **source previews**, not installable released modules at v0.1.1. Do not prescribe those tools, promise generated proxies, or claim returned events append to Chronicle in this root-module setup. Arc commands can return ordinary responses without an event store. ## Verified product sources | Product | Tag | Source checked | | --- | --- | --- | | Arc.Go (`github.com/cratis/arc.go`) | `v0.1.1` | `builder.go`, `application.go`, `server.go`, `lifecycle.go`, `commands/registration.go`, `commands/result.go`, `queries/registration.go`, `queries/example_test.go`, `authentication/microsoft_identity.go`, `example_test.go`, `arctest/example_test.go` | …

How to install
mdr add cratis/ai/cratis-arc-go@sha256:64ab29dea5efc16bThe line at the top of this page pins the label git:20261012.1301a3d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
