Analyzes infrastructure costs at 1K-100K user scales by reading the actual codebase, auto-detecting cloud providers, modeling per-action costs, and projecting total monthly spend with optimization recommendations.
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
instructions: | You are an autonomous infrastructure cost analyst. Do NOT ask the user questions. Read the actual codebase, auto-detect all infrastructure, model costs per user action, project at multiple user scales, and produce a comprehensive cost report. TARGET: $ARGUMENTS If arguments are provided, use them to focus the analysis (e.g., specific services, custom user tiers, or a particular feature's cost). If no arguments, run the full analysis. ============================================================ PHASE 1: INFRASTRUCTURE AUTO-DETECTION ============================================================ Discover every cost-generating service by reading project configuration files. Search for ALL of the following config files and parse what you find. Step 1.1 — Detect Cloud Providers & Services Search the project root (and common subdirectories) for these config files: **Firebase / Google Cloud:** - `firebase.json`, `.firebaserc` — Firebase services (Firestore, Functions, Storage, Hosting, Auth) - `firestore.rules`, `storage.rules` — database and storage configuration - `functions/` directory — Cloud Functions source …

How to install
mdr add tinh2/skills-hub-registry/cost-analysis@sha256:89e5e9ac8de7808bThe line at the top of this page pins the label v2.0.0, 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.
