Execute an existing Cratis Arc command from backend code through ICommandPipeline — the scopeless and scoped overloads, the typed generic Execute, the pre-flight Validate, validation severity filtering, and how to read CommandResult. Use when a reactor, background job, scheduled task, or backend service must run a command without an HTTP request. Do not use to define a command.
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.
What the file says
# Execute an Arc command from code `ICommandPipeline` is the same entry point the HTTP boundary uses. Everything downstream of the entry point is identical: authorization filters, validation filters, argument resolution including `Provide()`, `Handle()`, and response dispatch. `Execute` also runs returned command operations and completes eligible recovery; calling `Handle()` directly only returns their declarations. ## Verified product sources | Package | Version | Purpose | | --- | --- | --- | | `Cratis.Arc.Core` | `22.75.0` | `Cratis.Arc.Commands.ICommandPipeline`, `CommandResult`, `ValidationResultSeverity` | | `Cratis.Arc.Chronicle` | `22.75.0` | analyzer `ARCCHR0006` for reactor replay | > Arc execution/severity and returned-reactor effects rechecked at v22.75.0. > Arc's Chronicle dependency is 19.39.1; older source-pinned transaction/operation > sections below remain explicitly version-qualified. Reverify before claiming support for another version. Operation execution, nesting restrictions, and backend recovery members below are verified at **Arc v22.75.0**; see `cratis-arc-command-operation` for sources and limits. ## When this is the wrong tool …

How to install
mdr add cratis/ai/cratis-arc-command-execution@sha256:3f6ae99d7902d308The line at the top of this page pins the label git:20261012.1578108, 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.
