Estimate the monthly cost of a Pulumi or Terraform project with the FinFocus CLI, flag expensive resources, cost increases, and total cost against thresholds in .cost-check.yml, and write a COST_CHECK.md report. Reads machine-readable JSON, checks the CLI version, and names what to do when the CLI, a plugin, credentials, or a plan is missing. Use when checking infrastructure costs, reviewing the cost impact of a change, or gating CI on cost. Triggers on: "cost check…
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.

Install: `npx skills add rshade/finfocus -s cost-check`. **Required CLI: finfocus v0.5.0 or newer.** Update this line with the release the skill was last run against. **Core principle:** read the numbers the CLI returns. Never estimate a price by hand, never parse the table output, and never report an unpriced resource as `$0`. ## 1. Detect the input | Found in the project | Input | Status | | --- | --- | --- | | `Pulumi.yaml` or `Pulumi.yml` (this directory or a parent) | `--pulumi-json plan.json`, or auto-detect | supported | | `terraform.tfstate` | `--terraform-state terraform.tfstate` | supported, state only | | `*.tf` with no state file | none | not supported: Terraform plan input is not available as of v0.5.0 | Terraform: the CLI prices what is in the state file, so a state that does not exist yet or is stale gives no estimate for the pending change. Say so in the report. Do not run `terraform plan` and do not convert its output. When …

How to install
mdr add rshade/finfocus/cost-check@sha256:a95a30009e4e8770The line at the top of this page pins the label git:20261027.f851fe4, 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.
