harness-policy-governance

harness-policy-governance is a skill for Claude Code from dungnotnull/hybrid-harness-chaos-process-prm. It costs 100 tokens per session (2,173 once invoked), scanned A, original, MIT.

A set of governance policies for Harness, a platform for building and deploying software, using OPA (Open Policy Agent), a tool that checks machine-readable rules. The policies can cover pipeline tags, deployment times, approvals, container security, and chaos-testing gates.

In plain words
What is it for?
Use it to write, enforce, and audit OPA policies for Harness pipelines and entities, including approval requirements, required tags, deployment windows, security checks, and resilience gates.
Why use it?
It catches policy and compliance violations during the delivery process, before an unsafe or unauthorized change reaches deployment. It turns organizational requirements into rules that can warn or block pipelines.

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-policy-governance 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 12d 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 Policy Governance (OPA)

Purpose

Encode organizational compliance, security, and operational standards as machine-enforceable OPA policies that block or warn on violations before harm occurs — rather than detecting problems after deployment.


Input Contract

Input Source Required
All pipeline YAML outputs s04, s09 Yes
Compliance requirements s01 PRD Yes
Blast radius policies s14 output Yes
Template enforcement needs s09 output No
Cost governance needs s23 output No
Risk tolerance preferences s02 taste (risk_tolerance) Yes

Output Contract

Output Destination Format
OPA policy set YAML .commandcode/artifacts/policy-set.yaml YAML
Pipeline tagging policy .commandcode/artifacts/policy-tagging.rego Rego
Deployment window policy .commandcode/artifacts/policy-deploy-window.rego Rego
Production approval policy .commandcode/artifacts/policy-approval.rego Rego

Chaos gate policy .commandcode/artifacts/policy-chaos-gate.rego Rego
Cost governance policy .commandcode/artifacts/policy-cost.rego Rego
Policy audit report s25 (postmortem context) Markdown

Prerequisites

  • Harness Policy Engine module enabled
  • OPA basics understood (Rego language)
  • Compliance requirements documented (required tags, approval rules, deployment windows)
  • RBAC roles defined (who can override a policy warning)

Policy Enforcement Points

Harness evaluates OPA policies at these events:

Event Policies Evaluated On
OnSave Entity YAML saved in UI or API
OnRun Before pipeline execution begins
OnStep Before specific step executes
OnStepComplete After step completes

Policy Structure (Rego)

package <domain>

# Always include:
deny[reason] {
  # condition that should NOT be true
  # reason: human-readable explanation string
}

warn[reason] {
  # non-blocking warning condition
}

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
