cost-opt

What This Skill Does

The cost-opt skill provides a structured, multi-stage methodology for managing and reducing cloud infrastructure expenditure. Rather than providing scattered, superficial tips, this skill acts as a technical advisor that guides the user through four rigorous stages: context clarification, strategic design, implementation validation, and operational governance. By enforcing a procedural approach, it ensures that cost-saving measures—such as rightsizing instances, applying commitment-based reservations, or eliminating idle resources—are executed without compromising system availability or performance. The skill forces the user to explicitly define constraints, identify failure modes, and establish verification loops for every change, ensuring that 'optimization' does not inadvertently lead to architectural fragility or security regressions.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/clawkk/cost-opt

Use Cases

This skill is intended for cloud engineers, DevOps practitioners, and financial operations (FinOps) specialists who need to perform deep-dive cost reviews. Primary use cases include:

• Executing a quarterly cloud infrastructure audit to identify underutilized resources.
• Transitioning from on-demand to savings plans or reserved instances for predictable workloads.
• Planning a complex migration or re-architecture project where budget constraints are the primary driver.
• Establishing a culture of cost awareness by implementing guardrails and stakeholder reporting processes for technical teams.

Example Prompts

1. "I need to reduce our AWS spend by 20% this quarter without impacting our production latency; can you walk me through the cost-opt workflow?"
2. "We have a cluster of idle RDS instances that we need to decommission. How should I plan this migration to ensure we don't break our staging dependencies?"
3. "Start the cost-opt process for our GCP project. I want to focus on rightsizing our GKE node pools first; skip the reservations stage for now."

Tips & Limitations

The cost-opt skill is most effective when provided with concrete telemetry data (e.g., current utilization metrics, billing tags, or architectural diagrams). It is designed to be procedural, not autonomous; it will prompt you for specific constraints, and you should provide them honestly to ensure safe recommendations. Be aware that this skill prioritizes system stability; if it identifies a change as high-risk, it will mandate verification loops like canary deployments or peer reviews. If you are in a rush and do not want to follow the full four-stage methodology, you can explicitly ask the agent to switch to 'freeform' mode at any time.
