OpenSDD CLI (osdd)

The OpenSDD CLI lets you discover and run OpenSDD recipes from your terminal using your AI IDE of choice.

Think of it as Terraform for AI flows.

Installation

Option 1: Homebrew (macOS & Linux)

brew install opensdd/tap/osdd

# verify
osdd version

Option 2: Download a Release Binary

1. Visit the releases page.
2. Download the artifact for your platform:

• osdd-macos-x64 (macOS)
• osdd-linux-x64 (Linux)
• osdd-windows-x64.exe (Windows)

1. Place the binary on your PATH and make it executable (macOS/Linux):

chmod +x osdd
sudo mv osdd /usr/local/bin/
osdd version

Windows users can run osdd.exe directly or move it to a directory listed in %PATH%.

Option 3: Build from Source (advanced)

Requires Go 1.25.1 or newer.

git clone https://github.com/opensdd/osdd-cli.git
cd osdd-cli
make build        # or: make build-dev for a dev build
./osdd version

Example

Let’s start with an example — the documentation website was prepared using an OpenSDD recipe!

We have created an astro_site recipe, which is instructed to generate a documentation website based on Astro Starlight and published to GitHub Pages. All you need to do is install the OSDD CLI

brew install opensdd/tap/osdd

and run the following command:

osdd recipe execute astro_site -i codex

The CLI asks for user input, specifically in this case for the name of the web site, repo where the website should be generated, any context information (other websites, local files, other git repos, etc) and for any other instructions on how to generate the website. Then it launches the provided IDE (in this case - codex) and gets to work!

How exactly does this work?

In a nutshell, this command:

1. Downloaded this recipe - astro_site.
2. Asked for user input, which is also pre-configured in the recipe,
3. Created a new workspace directory in ~/osdd/workspace/astro_site for recipe’s instruction.
4. Downloaded all the context files and commands into the workspace.
5. Launched codex with the instruction to run /astro_run command, which maps to this prompt.

After a while, the codex was done and the website was generated and after a couple tweaks, it was published and here it is!

Quick Start

Pick a recipe Browse opensdd/recipes to find an automation. Recipes are identified by the name of the folder in this repository, for example: docs_update 1.

Run the recipe

osdd recipe execute astro_site --ide claude

• --ide names the IDE integration (claude, codex).
• The CLI fetches the recipe, and prompts for any declared user inputs.

Follow the prompts Provide requested information (multi-line text, options, and so on). When you finish, the CLI materializes files, configures workspaces, and executes the recipe steps. 1.

Follow the execution in the IDE The CLI will start the IDE requested and will optionally prompt it to start the work (depends on the recipe). You may need to pay attention to what the IDE is doing, since it may request permissions or confirmations.

Command Reference

osdd recipe execute <ID>                # run a recipe by ID
osdd recipe execute <ID> --ide <name>   # required IDE identifier

Running a Recipe

osdd recipe execute docs_update --ide claude

Flags to know:

• --ide selects which IDE integration to launch (Codex, Claude, etc.).
• --recipe-file lets you point to a local manifest when authoring new automations.

Using Your Own Recipes

The CLI also supports running recipes from an arbitrary publicly available repository. All you need to do is to create a folder opensdd_recipes in the repository root and add a folder with then name of the recipe in it and a recipe.yaml as a recipe declaration.

For example, a recipe from

https://github.com/<OWNER>/<REPO_NAME>/blob/main/opensdd_recipes/<RECIPE_NAME>/recipe.yaml

can be executed using

osdd recipe execute <OWNER>/<REPO_NAME>/<RECIPE_NAME> --ide claude

Why It Matters

• Helper role – The CLI is a facilitator, not a gatekeeper. It ensures every automation starts with the right context and guardrails.
• Repeatability – Recipes encode best practices, like mandatory planning or review loops, so teams don’t reinvent the process every time.
• Observability – Logs and generated artifacts live alongside your specs, enriching the OpenSDD knowledge base.
• Shareable – You can now just share id of a recipe you created and let others try it out. No need to copy/paste prompts, download files manually, etc.
• Interoperability – Recipes work the same way (well, almost) across different IDEs/CLIs. E.g. the example above can be executed with either Claude or Codex, despite Codex formally not having support for slash-commands or even project-level prompts. OSDD takes care of instructing each coding agent the right way.
