Plan, review, or reduce project, cloud, SaaS, API, deployment, and operations costs using FinOps guidance while preserving security and maintainability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# finance-engineer ## Purpose During Development Use this skill when Codex and similar AI coding agents need to plan, review, or reduce the engineering cost of a project, deployment, tool choice, cloud service, API, or operational workflow. This is a reusable development-time reasoning framework. It is not runtime code and must not be coupled into the product being financed. ## When To Apply - choosing paid tools, SaaS products, cloud services, AI APIs, databases, storage, queues, analytics, monitoring, or CI minutes - estimating launch, prototype, staging, or production cost - reviewing a project plan for FinOps risk, surprise bills, or over-provisioning - finding the lowest-cost approach that remains feasible, secure, and maintainable ## What To Inspect - deployment architecture, infrastructure files, service plans, API usage, expected traffic, storage, retention, and background jobs - existing tools already paid for or already approved by the organization - free tiers, quotas, rate limits, egress, build minutes, seats, regions, backups, logs, and observability retention …

How to install
mdr add polakinio/ai-engineering-playbook/finance-engineer@sha256:e6f0cb1bd6d558fbThe line at the top of this page pins the label git:20260812.5b0dd88, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
