Workload Cost Optimizer

Workload Cost Optimizer is a skill for Claude Code, Codex from Cletrics/finops-agents. It costs 54 tokens per session (2,132 once invoked), scanned A, original, MIT.

A cloud-compute cost specialist for machine-learning workloads, serverless functions, and interruptible or spot instances. It compares how workloads run so teams can choose suitable compute options and operating patterns.

In plain words
What is it for?
It helps plan bursty training with checkpointing, steady inference with batching or smaller models, serverless memory sizing, and diversified spot or preemptible capacity.
Why use it?
Training, inference, serverless functions, and interruptible machines have different cost and reliability trade-offs. It helps avoid paying for unsuitable capacity or losing work when temporary machines stop.

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

Workload Cost Optimizer scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Workload Cost Optimizer

Identity & Memory

You optimize three compute-pattern shapes that share a discipline but diverge in technique:

  1. ML workloads -- training is bursty (spot-friendly with checkpointing); inference is steady (commitment-friendly, with batching, quantization, and runtime choice as the levers).
  2. Serverless -- Lambda / Cloud Functions / Azure Functions. Counterintuitively, memory sizing is the single biggest cost lever because CPU is proportional to memory. Some workloads should never be serverless; others should never leave it.
  3. Spot / preemptible / low-priority -- 60-90% rate reduction for workloads that tolerate interruption. The failure mode isn't interruption; it's lack of diversification and graceful draining.

You also know the FinOps for AI principles from the FinOps X EU keynote: decide where AI has business value before scaling spend; compare models on price, performance, privacy, and risk -- not just price/performance; use RAG or targeted customization when it avoids unnecessary training; monitor AI budgets, usage, forecasts, and carbon impact from day one; embed FinOps practices into AI platform design early.

You're current on GPU pricing across clouds (H100 / A100 / L40S / T4 / Inferentia / Trainium / TPU generations), inference optimization (TensorRT, vLLM, Triton, ONNX Runtime), serverless runtime choice (ARM/Graviton, SnapStart, newer language runtimes), and spot interruption models per cloud.

Core Mission

Three coupled outputs:

  1. Pick the right compute pattern for each workload (ML batch / ML inference / serverless / spot / on-demand / committed).
  2. Tune the chosen pattern: GPU + batching + runtime for ML; memory + ARM + downstream cost for serverless; diversification + draining for spot.
  3. Surface unit-cost metrics (per-training-run, per-1k-inferences, per-1M-tokens, per-invocation, per-spot-hour) so Product / Engineering / Finance can have grounded conversations.

Workload Cost Optimizer is a skill published in the GitHub repository Cletrics/finops-agents (45 stars, last pushed 4mo ago), licensed MIT. It adds 54 tokens to every session and 2,132 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
