cost-analysis SKILL.md skillA
cost-analysis from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/cost-analysis@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Estimate and attribute cloud running cost for a proposed architecture before it is built. Use when writing an ADR options table, sizing a prototype, comparing managed versus self-hosted services, or answering "what will this cost to leave running". Produces a load-enveloped estimate with an idle-versus-active split and per-option attribution.
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
# Cost Analysis > **Purpose**: Make running cost a first-class, comparable dimension of an architecture decision -- not a surprise discovered after deployment. --- ## When to Use This Skill - Writing an ADR: every option in the comparison table needs a cost column - Sizing a prototype that will sit idle most of its life - Choosing between managed, serverless, and always-on compute - A stakeholder asks "what does it cost to leave this running for a month?" **Do NOT use** for billing forensics on already-deployed resources -- that is an observability task, not an architecture task. --- ## Core Model: Idle Cost Is The Prototype Killer A prototype is active for a small slice of the month and idle for the rest. Total cost is therefore driven far more by the **idle floor** than by peak throughput. ``` monthly_cost = (active_hours * active_rate) + (idle_hours * idle_rate) + fixed_monthly ``` | Billing shape | `idle_rate` | Prototype impact | |---|---|---| | Consumption / serverless | ~0 | Cheap when idle -- prefer for prototypes | | Auto-pause (serverless DB) | storage floor only | Cheap, small floor remains | …

How to install
mdr add jnpiyush/agentx/cost-analysis@sha256:30c7811c031d93e6The line at the top of this page pins the label v1.0.0, 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.
