Installation

DADR is the standard: the decision record format and the project vocabulary.

DADRock is a Rust tool that implements DADR. It previews, creates, edits, and validates decision records, and it can direct local LLM agents through tasks on the decision ledger. Everything it writes is a Markdown file you could have written yourself.

dadrock init
dadrock new "Decision title"
dadrock preview
dadrock accept ID
dadrock validate

Running dadrock without a subcommand prints help. preview starts the local web interface, normally at port 4004.

DADRock is a single binary. The web interface is embedded in it, so a complete build needs Rust and Bun; a CLI-only build needs Rust alone.

From source¶

Clone the repository and build with Cargo:

git clone https://github.com/vincentarelbundock/dadr.git
cd dadr
DADROCK_REQUIRE_JS_BUILD=1 cargo install --path crates/dadrock --bin dadrock
dadrock --version

The first build downloads dependencies and may take several minutes. DADROCK_REQUIRE_JS_BUILD=1 makes the build fail rather than silently skip the web interface when Bun is missing.

Without the web interface¶

For servers and continuous integration, build the command line only:

cargo install --path crates/dadrock --bin dadrock --features no-js-build

dadrock preview then shows a notice instead of the interface; every other command works. Install from a pinned revision for reproducibility.

Optional: a local agent¶

Drafting and conflict checks use a local agent speaking the Agent Client Protocol, such as claude-agent-acp. DADRock detects one on PATH automatically; see LLM agents to configure a specific provider. Nothing else in DADRock depends on it.

Next¶

Open the web interface or the standalone app, set up your editor, or read what a Data Analysis Decision Record is.
