Overview

Generate Harness v0 Pipeline YAML for CI/CD workflows and create them via MCP. Supports CI stages (build, test, Docker push), CD stages (Kubernetes, Helm, ECS, serverless), approval gates, parallel execution, matrix strategies, and failure rollback. Use when asked to create a pipeline, build pipeline, deployment pipeline, CI/CD workflow, or set up Harness pipelines. Do NOT use for v1 simplified pipelines (use create-pipeline-v1). Trigger phrases: create pipeline, build pipeline, deployment pipeline, CI/CD, Harness pipeline, Kubernetes deploy pipeline.

Create Pipeline

Generate Harness v0 Pipeline YAML and optionally push to Harness via MCP.

Instructions

Analyze codebase (if source code is available) - Scan the project to auto-detect language, build tools, test frameworks, containerization, deployment manifests, and target infrastructure. Use the detection tables and decision tree in references/codebase-analysis.md to determine:
- Language and runtime version (package.json → Node.js, go.mod → Go, pom.xml → Java, etc.)
- Build commands and base images
- Test framework and report format (Jest → JUnit, pytest → JUnit XML, etc.)
- Linter and formatter (ESLint, Prettier, Ruff, etc.)
- Dockerfile presence and registry type (Docker Hub, ECR, GCR, ACR)
- Deployment manifests → Harness service/deployment type (k8s manifests → Kubernetes, Chart.yaml → NativeHelm, task-definition.json → ECS, serverless.yml → ServerlessAwsLambda)
- Existing CI/CD configs for migration (GitHub Actions, Jenkins, GitLab CI, etc.)
Clarify requirements - Confirm detected settings with the user. Ask about anything that couldn't be auto-detected — do not guess or use placeholders. If the user's request is ambiguous, ask before generating YAML. Examples of what to ask when missing:
- Deployment target / infrastructure: region (e.g. us-east-1), cluster name or ID, account ID (e.g. AWS account for ECR/ECS)
- Registry: which registry (Docker Hub, ECR, GCR, ACR), registry identifier/URL, repo path
- Cloud provider: which account, region, and resource identifiers for connectors/infrastructure
- Approval gates, notification channels if relevant Critical rule: Never hardcode placeholder values (e.g. 123456789012, us-east-1, my-cluster) for deployment target, region, registry, or cluster when the user did not specify them — ask the user instead. If the user did not specify region, account ID, cluster, or registry (e.g. "deploys to ECS" with no region or cluster), ask the user for those values before generating YAML.
Select native steps - Always prefer Harness native steps over Run or ShellScript steps. Consult references/native-steps.md for the full mapping. Key rules:
- Docker build/push → use BuildAndPushDockerRegistry / BuildAndPushECR / BuildAndPushGCR / BuildAndPushACR (never Run: docker build && docker push)
- K8s deploy → use K8sRollingDeploy / K8sBlueGreenDeploy / K8sCanaryDeploy (never Run: kubectl apply)
- Helm deploy → use HelmDeploy (never Run: helm upgrade --install)
- ECS deploy → use EcsRollingDeploy (never Run: aws ecs update-service)
- Terraform → use TerraformPlan / TerraformApply (never Run: terraform apply)
- Security scanning → use native STO steps (AquaTrivy, Snyk, Sonarqube, Semgrep, etc.)
- Uploads → use S3Upload / GCSUpload (never Run: aws s3 cp)
- Approvals → use HarnessApproval / JiraApproval (never polling scripts)
- Ticketing → use JiraCreate / ServiceNowCreate (never Run: curl)
- Use Run steps only for custom build/test/lint commands with no native equivalent
- Test steps: Any Run step that runs unit or integration tests must include a reports block (e.g. type: JUnit, spec.paths) so Harness can capture results; see references/codebase-analysis.md for framework → report path.
Generate valid YAML following the structure below, using the detected build/test/deploy commands. Validation rules: (a) Stage names must match ^[a-zA-Z_0-9-.][-0-9a-zA-Z_\\s.]{0,127}$ — use only letters, numbers, spaces, hyphens, underscores, or periods (no commas). (b) Every CI and CD stage must include a failureStrategies array (Approval stages do not require one). For CI use MarkAsFailure (never Ignore — it hides failures); for CD use StageRollback.
Optionally create via MCP — First verify the project exists (see "Creating via MCP" section below), then use harness_create with resource_type pipeline and body: { yamlPipeline: "<YAML string>" }

Pipeline Structure

    type: CI
    spec:
      cloneCodebase: true
      platform:
        os: Linux
        arch: Amd64
      runtime:
        type: Cloud    # Cloud, Kubernetes, VM, Docker

          errors: [AllErrors]
          action:
            type: MarkAsFailure

CD Stage (type: Deployment)

- stage:
    identifier: deploy
    name: Deploy

Approval Stage (type: Approval)

HarnessApproval requires approvers.disallowPipelineExecutor (required by the API). Set it to true so the pipeline executor cannot approve their own run; omit it and the API returns "disallowPipelineExecutor: is missing but it is required".

- stage:
    identifier: approval
    name: Approval
    type: Approval
    spec:
      execution:
        steps:
          - step:

              name: Approve
              type: HarnessApproval
              spec:
                approvalMessage: "Please review and approve"
                approvers:
                  userGroups: [prod_approvers]
                  minimumCount: 1
                  disallowPipelineExecutor: true
                includePipelineExecutionHistory: true
              timeout: 1d
    failureStrategies:
      - onFailure:
          errors: [AllErrors]
          action:
            type: Abort

Common Step Types

Run Step

- step:
    identifier: run_tests
    name: Run Tests
    type: Run
    spec:
      shell: Bash          # Sh, Bash, Powershell, Pwsh, Python
      command: |
        npm ci
        npm test
      envVariables:
        NODE_ENV: test
      reports:
        type: JUnit
        spec:
          paths: ["junit.xml"]

Build and Push Docker

- step:
    identifier: docker_push
    name: Build and Push
    type: BuildAndPushDockerRegistry
    spec:
      connectorRef: dockerhub
      repo: myorg/myimage
      tags: [latest, <+pipeline.sequenceId>]
      dockerfile: Dockerfile

K8s Rolling Deploy

- step:
    identifier: rollout
    name: Rollout
    type: K8sRollingDeploy
    spec:
      skipDryRun: false
    timeout: 10m

K8s Rolling Rollback

- step:
    identifier: rollback
    name: Rollback
    type: K8sRollingRollback
    spec: {}
    timeout: 10m

For the complete catalog of 300+ native step types (cloud deployments, security scanners, IaC, ticketing, approvals, GitOps, and more), consult references/native-steps.md. Always check this reference before using a Run step.

Variables and Expressions

pipeline:
  variables:
    - name: env
      type: String
      default: dev
    - name: api_key
      type: Secret
      value: <+secrets.getValue("api_key")>

Common expressions:

<+pipeline.variables.env> - Pipeline variable
<+stage.variables.VAR> - Stage variable
<+steps.step_id.output.outputVariables.VAR> - Step output
<+trigger.branch>, <+trigger.commitSha> - Trigger info
<+secrets.getValue("name")> - Secret reference
<+pipeline.sequenceId> - Build number

Parallel Execution

# Parallel steps
- parallel:
    - step: ...
    - step: ...

# Parallel stages
stages:
  - parallel:
      - stage: ...
      - stage: ...

Failure Strategies

failureStrategies:
  - onFailure:
      errors: [AllErrors]     # AllErrors, Timeout, Authentication, Connectivity
      action:
        type: StageRollback   # Ignore, Retry, MarkAsSuccess, Abort, StageRollback, PipelineRollback

Conditional Execution

- stage:
    when:
      pipelineStatus: Success
      condition: <+pipeline.variables.deploy> == "true"

Matrix Strategy

Placement: strategy must be at the stage level, as a sibling of spec, not inside spec. If you put strategy under spec, the matrix will not be applied and the UI will not show matrix iterations.

Reference matrix values in steps with <+stage.matrix.TAG> (e.g. <+stage.matrix.python_version>). Use hyphen-free dimension names (e.g. python_version not python-version).

- stage:
    identifier: test_matrix
    name: Test Matrix
    type: CI
    spec:
      cloneCodebase: true
      platform:
        os: Linux
        arch: Amd64
      runtime:
        type: Cloud
        spec: {}
      execution:
        steps:
          - step:
              type: Run
              spec:
                image: node:<+stage.matrix.node_version>
                command: npm test
    strategy:
      matrix:
        node_version: ["16", "18", "20"]
        os: [linux, macos]
      maxConcurrency: 3
    failureStrategies:
      - onFailure:
          errors: [AllErrors]
          action:
            type: Abort

Creating via MCP

After generating the YAML, create it in Harness:

Verify the project exists — List projects with harness_list (resource_type: project, org_id) to confirm. If the project does not exist, create it first with harness_create (resource_type: project, body: { identifier, name }) or ask the user.
Create the pipeline — Use harness_create with the pipeline YAML serialized as a yamlPipeline string in the body. Do not pass a nested JSON pipeline object; it causes serialization errors.

Call MCP tool: harness_create
Parameters:
  resource_type: "pipeline"
  org_id: "<organization>"
  project_id: "<project>"
  body: { yamlPipeline: "<full pipeline YAML string, including 'pipeline:' root key>" }

Example body (abbreviated):

{
  "yamlPipeline": "pipeline:\n  identifier: nodejs_ci\n  name: Node.js CI\n  projectIdentifier: my_project\n  orgIdentifier: default\n  stages:\n    - stage:\n        identifier: build\n        ..."
}

To update an existing pipeline, use the same yamlPipeline format:

Call MCP tool: harness_update
Parameters:
  resource_type: "pipeline"
  resource_id: "<pipeline_identifier>"
  org_id: "<organization>"
  project_id: "<project>"
  body: { yamlPipeline: "<full updated pipeline YAML

## Instructions

1. **Analyze codebase** (if source code is available) - Scan the project to auto-detect language, build tools, test frameworks, containerization, deployment manifests, and target infrastructure. Use the detection tables and decision tree in `references/codebase-analysis.md` to determine:

   - Dockerfile presence and registry type (Docker Hub, ECR, GCR, ACR)
   - Deployment manifests → Harness service/deployment type (k8s manifests → Kubernetes, Chart.yaml → NativeHelm, task-definition.json → ECS, serverless.yml → ServerlessAwsLambda)
   - Existing CI/CD configs for migration (GitHub Actions, Jenkins, GitLab CI, etc.)
2. **Clarify requirements** - Confirm detected settings with the user. **Ask about anything that couldn't be auto-detected** — do not guess or use placeholders. If the user's request is ambiguous, ask before generating YAML. Examples of what to ask when missing:
   - **Deployment target / infrastructure:** region (e.g. us-east-1), cluster name or ID, account ID (e.g. AWS account for ECR/ECS)

## Pipeline Structure

```yaml
pipeline:
  identifier: my_pipeline       # ^[a-zA-Z_][0-9a-zA-Z_]{0,127}$
  name: My Pipeline
  orgIdentifier: default
  projectIdentifier: my_project
  tags: {}
  properties:
    ci:
      codebase:                  # Required for CI stages
        connectorRef: github_connector
        repoName: my-repo
        build:
          type: branch
          spec:
            branch: <+trigger.branch>
  stages:
    - stage: ...
```

## Stage Types

### CI Stage (type: CI)

```yaml
- stage:
    identifier: build
    name: Build
    type: CI
    spec:
      cloneCodebase: true
      platform:
        os: Linux
        arch: Amd64
      runtime:
        type: Cloud    # Cloud, Kubernetes, VM, Docker
        spec: {}
      execution:
        steps:
          - step: ...
    failureStrategies:
      - onFailure:
          errors: [AllErrors]
          action:
            type: MarkAsFailure
```

### CD Stage (type: Deployment)

```yaml
- stage:
    identifier: deploy
    name: Deploy
    type: Deployment
    spec:
      deploymentType: Kubernetes  # Kubernetes, NativeHelm, ECS, ServerlessAwsLambda, Ssh, WinRm, AzureWebApp
      service:
        serviceRef: my_service
      environment:
        environmentRef: dev
        infrastructureDefinitions:

          action:
            type: StageRollback
```

### Approval Stage (type: Approval)

`HarnessApproval` requires `approvers.disallowPipelineExecutor` (required by the API). Set it to `true` so the pipeline executor cannot approve their own run; omit it and the API returns "disallowPipelineExecutor: is missing but it is required".

```yaml
- stage:
    identifier: approval
    name: Approval
    type: Approval
    spec:
      execution:
        steps:
          - step:

                  minimumCount: 1
                  disallowPipelineExecutor: true
                includePipelineExecutionHistory: true
              timeout: 1d
    failureStrategies:
      - onFailure:
          errors: [AllErrors]
          action:
            type: Abort
```

## Common Step Types

### Run Step

```yaml
- step:
    identifier: run_tests
    name: Run Tests
    type: Run
    spec:
      shell: Bash          # Sh, Bash, Powershell, Pwsh, Python
      command: |
        npm ci
        npm test
      envVariables:
        NODE_ENV: test
      reports:
        type: JUnit
        spec:
          paths: ["junit.xml"]
```

### Build and Push Docker
```yaml
- step:
    identifier: docker_push
    name: Build and Push
    type: BuildAndPushDockerRegistry
    spec:
      connectorRef: dockerhub
      repo: myorg/myimage
      tags: [latest, <+pipeline.sequenceId>]
      dockerfile: Dockerfile
```

### K8s Rolling Deploy
```yaml
- step:
    identifier: rollout
    name: Rollout
    type: K8sRollingDeploy
    spec:
      skipDryRun: false
    timeout: 10m
```

### K8s Rolling Rollback
```yaml
- step:
    identifier: rollback
    name: Rollback
    type: K8sRollingRollback
    spec: {}
    timeout: 10m
```

For the complete catalog of 300+ native step types (cloud deployments, security scanners, IaC, ticketing, approvals, GitOps, and more), consult `references/native-steps.md`. Always check this reference before using a `Run` step.

## Variables and Expressions

```yaml
pipeline:
  variables:
    - name: env
      type: String
      default: dev
    - name: api_key
      type: Secret
      value: <+secrets.getValue("api_key")>
```

Common expressions:
- `<+pipeline.variables.env>` - Pipeline variable
- `<+stage.variables.VAR>` - Stage variable
- `<+steps.step_id.output.outputVariables.VAR>` - Step output
- `<+trigger.branch>`, `<+trigger.commitSha>` - Trigger info
- `<+secrets.getValue("name")>` - Secret reference
- `<+pipeline.sequenceId>` - Build number

## Parallel Execution

```yaml
# Parallel steps
- parallel:
    - step: ...
    - step: ...

# Parallel stages
stages:
  - parallel:
      - stage: ...
      - stage: ...
```

## Failure Strategies

```yaml
failureStrategies:
  - onFailure:
      errors: [AllErrors]     # AllErrors, Timeout, Authentication, Connectivity
      action:
        type: StageRollback   # Ignore, Retry, MarkAsSuccess, Abort, StageRollback, PipelineRollback
```

## Conditional Execution

```yaml
- stage:
    when:
      pipelineStatus: Success
      condition: <+pipeline.variables.deploy> == "true"
```

## Matrix Strategy

**Placement:** `strategy` must be at the **stage level**, as a **sibling of `spec`**, not inside `spec`. If you put `strategy` under `spec`, the matrix will not be applied and the UI will not show matrix iterations.

Reference matrix values in steps with `<+stage.matrix.TAG>` (e.g. `<+stage.matrix.python_version>`). Use hyphen-free dimension names (e.g. `python_version` not `python-version`).

```yaml
- stage:
    identifier: test_matrix
    name: Test Matrix
    type: CI
    spec:
      cloneCodebase: true
      platform:

## Creating via MCP

After generating the YAML, create it in Harness:

1. **Verify the project exists** — List projects with `harness_list` (resource_type: `project`, org_id) to confirm. If the project does not exist, create it first with `harness_create` (resource_type: `project`, body: `{ identifier, name }`) or ask the user.
2. **Create the pipeline** — Use `harness_create` with the pipeline YAML serialized as a **`yamlPipeline`** string in the body. Do not pass a nested JSON `pipeline` object; it causes serialization errors.

```
Call MCP tool: harness_create
Parameters:
  resource_type: "pipeline"
  org_id: "<organization>"
  project_id: "<project>"
  body: { yamlPipeline: "<full pipeline YAML string, including 'pipeline:' root key>" }
```

**Example body** (abbreviated):
```json
{
  "yamlPipeline": "pipeline:\n  identifier: nodejs_ci\n  name: Node.js CI\n  projectIdentifier: my_project\n  orgIdentifier: default\n  stages:\n    - stage:\n        identifier: build\n        ..."
}
```

To update an existing pipeline, use the same `yamlPipeline` format:

```
Call MCP tool: harness_update
Parameters:
  resource_type: "pipeline"
  resource_id: "<pipeline_identifier>"
  org_id: "<organization>"
  project_id: "<project>"
  body: { yamlPipeline: "<full updated pipeline YAML

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
