dagu

This is one of the largest Dagu releases so far. It turns workflows from a collection of commands into reusable, packageable automation units: steps can now be plain commands, built-in actions, or versioned Dagu actions with their own inputs, outputs, artifacts, and toolchain.

Highlights:

• Action schema v2 adds the new run, action, with, and outputs style for clearer workflow definitions while keeping existing workflows supported. See also workflow outputs.
• Remote Dagu Actions and Official Dagu Actions make reusable workflow packages possible. Actions can be referenced by version, resolve their own workspace, expose typed outputs, and run as sub-DAGs. DuckDB is provided as the official duckdb@v1 Dagu Action, not as a built-in action.
• DAG-level tools let workflows declare required CLIs and runtimes directly in YAML. Tool installation is powered by Aqua, so workers can prepare the right tools at runtime instead of baking everything into images.
• New built-in actions cover common workflow glue: file operations, artifact publishing and stream capture, data conversion and picking, waits, Git checkout, DAG enqueue, and structured output writing.
• Operations features now include Dagu-managed secrets, notification channels and rules, incident connections and routing, the Dagu MCP server, and configurable webhook payload limits.
• Execution behavior and reliability were tightened with graph as the default DAG type, better auto-retry notification behavior, deferred failure handlers during retries, richer Slack context for the agent, and no hard LLM request timeout for agent steps.

For example, the new Official Dagu Actions node-script@v1 and python-script@v1 let a workflow run small Node.js and Python glue steps without baking those runtimes into every worker image:

steps:
  - id: prepare_release
    action: node-script@v1
    with:
      input:
        version: "2.7.1"
      script: |
        return {
          tag: `v${input.version}`,
          channel: input.version.includes("-") ? "preview" : "stable"
        }

  - id: summarize
    action: python-script@v1
    with:
      input:
        tag: "${prepare_release.outputs.result.tag}"
        channel: "${prepare_release.outputs.result.channel}"
      script: |
        return {
            "message": f"release {input['tag']} is ready for {input['channel']}"
        }
    depends: 
      - prepare_release

  - id: print
    run: echo "${summarize.outputs.result.message}"
    depends:
      - summarize

The default DAG type is now graph. Existing workflows that omitted type and relied on implicit sequential execution should set type: chain, or add explicit depends, to preserve the previous ordering.

Acknowledgements

Special thanks to the aquaproj project and aqua. Dagu v2.7.0’s new DAG-level tools feature uses aqua internally to install pinned CLI tools reproducibly.
