harness_create

Create any Harness resource—pipelines, connectors, services, and more—by supplying the resource type and YAML or JSON definition. Supports remote Git and Harness Code pipelines with branch and file path details.

Instructions

Create a Harness resource. For pipelines/input sets: pass body as a YAML string directly (recommended for complex definitions), or use body.yamlPipeline (YAML string), or body.pipeline (JSON object). For remote pipelines, pass git details in params: external Git (store_type='REMOTE', connector_ref, repo_name, branch, file_path) or Harness Code (store_type='REMOTE', is_harness_code_repo=true, repo_name, branch, file_path). For others: call harness_describe for the body format.

Input Schema

TableJSON Schema

Name	Required	Description
`url`	No	A Harness UI URL — org, project, and supported resource_scope are extracted automatically
`body`	Yes	The resource definition body. For pipelines: pass a YAML string directly, or an object with yamlPipeline (YAML string) or pipeline (JSON object). For other resources: pass a JSON object
`org_id`	No	Organization identifier. Required for org- and project-scoped resources unless a Harness URL is passed. This session has no configured default (common in hosted/multi-user HTTP) — pass the current org_id on the first call. Do not omit it.
`params`	No	Additional parameters. For external Git pipelines: store_type='REMOTE', connector_ref, repo_name, branch, file_path, commit_msg. For Harness Code pipelines: store_type='REMOTE', is_harness_code_repo=true, repo_name, branch, file_path.
`confirm`	No	Set to true to confirm the operation. Only required when the operation risk is medium_write or above (most write resources) AND the client cannot surface a confirmation prompt — e.g. managed MCP that does not advertise elicitation, or an elicitation that fails at runtime. Has no effect for low-risk creates. Does NOT override an explicit decline from a client that completed an elicitation prompt — a user's decline is authoritative.
`project_id`	No	Project identifier. Required for project-scoped resources unless a Harness URL is passed. This session has no configured default (common in hosted/multi-user HTTP) — pass the current project_id on the first call. Do not omit it.
`resource_type`	Yes	The type of resource to create
`resource_scope`	No	Scope for the operation. account: account-level resources only — do not use account to skip a known org/project. org: org-level (org_id). project: org+project. Omit to use the resource's default scope. Auto-detected from url when present.

First observedv3.2.10Jul 16, 2026

A4.3/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover readOnly=false, idempotent=false, and destructive=false, so the write semantics are known. The description itself adds no extra behavioral detail such as side effects, failure modes, or reversibility beyond the create action, but it does not contradict annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences with no fluff, front-loaded with the action and then branching by resource family. The dense parameter enumerations are necessary for this surface area.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with ~80 resource types and two required params, the description covers the highest-complexity cases (pipelines and remote git) and defers generic bodies to harness_describe. The rich schema, output schema, and annotations carry the remaining details, so nothing needed to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description earns above baseline by explaining the recommended body as YAML, the body.yamlPipeline/body.pipeline variants, and the exact params keys for external Git vs Harness Code. It also routes unknown resource formats to harness_describe, reducing param guesswork.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with 'Create a Harness resource' — a specific verb and object — and the resource_type enum makes the scope concrete. The pipeline/input-set handling and remote-git branches further delineate exactly what this tool does, distinguishing it from update/delete/describe siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit branches: pipelines/input sets use YAML/body formats, remote pipelines require git params, and 'For others: call harness_describe for the body format' names an alternative for a sub-task. It lacks an explicit when-not-to-use statement vs update/delete, so it is not a perfect 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
