harness-template-library

harness-template-library is a skill for Claude Code from dungnotnull/hybrid-harness-chaos-process-prm. It costs 97 tokens per session (2,895 once invoked), scanned A, original, MIT.

A system for creating and managing reusable Harness pipeline parts. Harness is a platform for building and running software delivery pipelines, while templates are shared building blocks that teams can reuse.

In plain words
What is it for?
Creating and versioning Harness pipeline, stage, step, and step-group templates, plus rules and changelogs for governing their use.
Why use it?
It reduces copy-and-paste differences between pipelines and helps teams apply shared deployment, security, approval, and notification standards.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

harness-template-library scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Harness Template Library

Purpose

Build a governed library of reusable pipeline building blocks that enforce engineering standards, eliminate copy-paste drift, and allow teams to compose pipelines from pre-approved, versioned templates.


Input Contract

Input Source Required
Pipeline design patterns s04 output Yes
Security scan requirements s01 PRD or user No
Approval gate requirements s01 (compliance needs) Yes
Notification preferences s02 taste (communication) No
Service team structures s05 output No

Output Contract

Output Destination Format
Deploy stage template .commandcode/artifacts/template-deploy.yaml YAML
Security scan step group template .commandcode/artifacts/template-security.yaml YAML
Approval stage template .commandcode/artifacts/template-approval.yaml YAML
Notification step group template .commandcode/artifacts/template-notify.yaml YAML
Template enforcement OPA policy s22 (governance) Rego
Template version changelog .commandcode/artifacts/template-changelog.md Markdown

Prerequisites

  • Harness account with Template Library access
  • Engineering standards documented (what must be identical across all pipelines)
  • RBAC roles defined (who can create/modify templates vs use them)

Template Hierarchy

Account-level templates   → Shared across ALL orgs and projects
    └── Org-level templates       → Shared across all projects in org
            └── Project-level templates    → Used within one project

Template Types:
├── Pipeline Template      → Entire pipeline as a template
├── Stage Template         → One stage (CI, CD, Approval, etc.)
├── Step Template          → One step (Run, ShellScript, etc.)
└── Step Group Template    → A group of steps as a unit

Template Versioning Strategy

<template-identifier>
├── v1 — Stable (in use by 20+ pipelines)
├── v2 — Stable (new default)
└── v3 — Beta (testing phase)

Versioning rules:
- Patch (1.0 → 1.1): Non-breaking — add optional fields, fix bugs
- Minor (1.x → 2.0): Breaking — remove fields, change required inputs
- Always keep v_previous stable for 30 days after new version release
- Deprecation: set isStable: false, add deprecation notice in description
