Cost awareness principles — FinOps mindset, right-sizing, cost-per-request model, storage tier selection, cardinality explosion, log volume. Auto-load when reasoning about cloud costs, right-sizing instances, scale-to-zero trade-offs, or FinOps budget constraints.
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
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-COST-AWARENESS --> # Cost Awareness Cost bugs are design bugs. They are cheapest to fix before the first dollar is spent. This skill teaches design-time discipline — choosing the right tier, topology, and access pattern — not post-billing cost reduction tactics. ## FinOps Mindset Cost is a feature requirement, not an afterthought. Treat budget the same way you treat latency and availability SLOs. - Name a cost budget alongside the performance budget at design time. "Under $X/month at N req/s" is a testable acceptance criterion. - Cloud bills are emergent: small per-request charges multiply by request volume, retention windows, and replica count in ways that are invisible in local testing. - Assign cost ownership to the team that controls the resource. Shared cost pools obscure accountability and slow optimization. - Unit economics clarify decisions: cost-per-request, cost-per-GB-stored, cost-per-active-user. Derive these early; revisit when scale changes by 10×. ## Egress and Data Movement Egress is the most common billing surprise — data that moves costs more than data that sits still. …

How to install
mdr add lugassawan/swe-workbench/principle-cost-awareness@sha256:962d581dbfdee671The line at the top of this page pins the label git:20260828.71a6399, 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.
