+Steps are the sequential actions the workflow executes. Each step has a unique `id`, a `type`, and a `name`. Agent steps (`type: agent`) include a `prompt` with instructions for the AI agent.

+## Using command steps
+
+Not every step in a workflow needs an AI agent. Command steps let you run shell commands directly, which is useful for build tools, test suites, linters, or other CLI operations that don't require AI reasoning.
+
+A command step requires `type: command` and a `command` field instead of a `prompt`. You can optionally provide `args` as an array and set `allow_failure: true` to let the workflow continue even if the command fails.
+
+Here is an example workflow that builds a project, runs tests, and then uses an agent to analyze the results:
+
+```yaml
+version: '1.0'
+name: 'build-and-review'
+description: 'Build the project, run tests, and review the results'
+
+inputs:
+  - name: description
+    description: 'Describe what to focus on during the review'
+    type: string
+    required: true
+
+outputs:
+  - name: review_report
+    description: 'Review report with findings and recommendations'
+    type: file
+    filename: 'review_report.md'
+
+steps:
+  - id: build
+    type: command
+    name: 'Build Project'
+    command: npm run build
+
+  - id: test
+    type: command
+    name: 'Run Tests'
+    command: npm run test
+    allow_failure: true
+
+  - id: review
+    type: agent
+    name: 'Review Results'
+    prompt: |
+      Review the build and test output for this project.
+
+      Focus on: {{inputs.description}}
+
+      Build output:
+      {{steps.build.outputs.stdout}}
+
+      Test output:
+      {{steps.test.outputs.stdout}}
+      {{steps.test.outputs.stderr}}
+
+      Write a review report summarizing the results and any issues found.
+    outputs:
+      - name: review_report
+        description: 'Review report with findings and recommendations'
+        type: file
+        filename: 'review_report.md'
+```
+
+Command steps capture `stdout` and `stderr` automatically, making them available to later steps through the template syntax.

+## Command Step Configuration
+
+Command steps execute **shell commands directly** without invoking an AI agent. They are useful for running build tools, test suites, linters, or any other CLI commands as part of a workflow.
+
+### Command Step Properties
+
+| Property | Type | Required | Description |
+|----------|------|----------|-------------|
+| `id` | string | **Yes** | Unique step identifier (used for referencing outputs) |
+| `type` | literal | **Yes** | Must be `'command'` |
+| `name` | string | **Yes** | Human-readable step name |
+| `command` | string | **Yes** | The command to execute |
+| `args` | array | No | Command arguments as an array of strings |
+| `allow_failure` | boolean | No | Whether to continue the workflow if the command fails (default: `false`) |
+| `outputs` | array | No | Outputs this step produces |
+
+### Command Execution
+
+The `command` field specifies the command to run. You can optionally provide `args` as a separate array for readability, or include all arguments directly in the `command` string — both forms are equivalent.
+
+Command steps automatically capture **`stdout`** and **`stderr`** as step outputs. Reference them in subsequent steps with the template syntax `{{steps.step_id.outputs.stdout}}` or `{{steps.step_id.outputs.stderr}}`.
+
+### Command Step Examples
+
+**Command with inline arguments**:
+```yaml
+steps:
+  - id: build
+    type: command
+    name: 'Build Project'
+    command: npm run build
+```
+
+**Command with separate arguments**:
+```yaml
+steps:
+  - id: test
+    type: command
+    name: 'Run Tests'
+    command: npm
+    args:
+      - run
+      - test
+```
+
+**Allow failure** (workflow continues even if the command exits with a non-zero code):
+```yaml
+steps:
+  - id: lint
+    type: command
+    name: 'Lint Code'
+    command: npm run lint
+    allow_failure: true
+```
+
+**Mixed workflow** (combine command and agent steps):
+```yaml
+steps:
+  - id: build
+    type: command
+    name: 'Build Project'
+    command: npm run build
+
+  - id: analyze
+    type: agent
+    name: 'Analyze Build Output'
+    prompt: |
+      Review the build output and identify any warnings:
+      {{steps.build.outputs.stdout}}
+```
+
