Read-only audit of hosting, database, storage, egress, and serverless spend (Supabase, Vercel, S3/R2, edge). Use when "hosting bill is high", "cut infra costs", or a bill jumps. CI minutes → audit-cicd. LLM tokens → plan-llm-cost-guardrails.
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
# audit-infra-cost — Hosting spend without hurting reliability **Degree of freedom: HIGH** — quantify and plan. Phase 2 stays plan-only until approved. Never propose a cut that weakens backups (`plan-backup-dr`). Read-only. Find where money leaks in the infra bill and plan cuts that do not trade away reliability. **For a solo operator, infra cost is runway.** A silent egress or storage leak can double a bill nobody is watching. > **Quantify and plan. Apply only on approval.** Never propose a cut that > weakens backups (`plan-backup-dr`) or user experience. ## This skill vs neighbors | Skill | Owns | |---|---| | **audit-infra-cost** (this) | Compute, storage, bandwidth, platform fees | | `audit-cicd` | GitHub Actions minutes / artifacts | | `plan-llm-cost-guardrails` | Model tokens / quota abuse | | `test-load` | Measured peak — right-size to this, not a guess | | `audit-bundle-size` / `audit-performance` | Client payload (feeds egress) | | `backend-db-performance` | The index that stops compute burn | ## How to reason 1. **Observe** — billed resource, pricing model, and (if exposed) the breakdown line …

How to install
mdr add kensaurus/skills/audit-infra-cost@sha256:65fba4794f07ceb0The line at the top of this page pins the label git:20260923.68c095e, 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.
