Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.02173 |
| Opus 5 | $0.00050 | $0.01086 |
| Sonnet 5 | $0.00020 | $0.00435 |
| Haiku 4.5 | $0.00010 | $0.00217 |
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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

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 |

# Always include:

# condition that should NOT be true
# reason: human-readable explanation string
}
warn[reason] {
# non-blocking warning condition
}
What this file has done since we first saw it
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.

harness-policy-governance is a skill published in the GitHub repository dungnotnull/hybrid-harness-chaos-process-prm (19 stars, last pushed 3mo ago), licensed MIT. It adds 100 tokens to every session and 2,173 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
