harness-cloud-cost

harness-cloud-cost is a skill for Claude Code from dungnotnull/hybrid-harness-chaos-process-prm. It costs 97 tokens per session (2,693 once invoked), scanned A, original, MIT.

A guide for analyzing and controlling spending on cloud infrastructure such as AWS, Google Cloud, Azure, and Kubernetes through Harness Cloud Cost Management. It covers budgets, cost views, waste, team allocation, and automated stopping rules.

In plain words
What is it for?
Use it to configure cloud accounts, budgets, cost reports, AutoStopping rules, cost-allocation views, and governance policies.
Why use it?
It helps teams see where cloud money goes, find unused resources, set spending controls, and connect costs to responsible teams.

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-cloud-cost 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.

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.
