Implement or audit usage credits with atomic reservations, spending, grants, purchases, expiration, refunds, limits, UI state, and an immutable ledger. Use when an app meters consumable usage.

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

# Credit metering

Build credits as a financial state machine. Preserve existing denominations, billing semantics, and provider integrations.

## Workflow

1. Inspect backend/runtime, database/ORM, auth and tenant keys, current balance/ledger fields, payment provider, usage paths, retries, queues, and frontend state.
2. Infer existing costs, grants, and packs from code. Ask only for unresolved commercial policy: denomination, per-action or measured cost, free/recurring grants, expiration/rollover, refund/clawback behavior, and overspend/debt policy. Never default to a new payment provider when one exists.
3. Read [database schemas](references/database-schemas.md), then implement only the matching database variant. Do not treat PostgreSQL, MySQL/PlanetScale, Prisma providers, and MongoDB as interchangeable.
4. Use an append-only ledger with a unique idempotency key/external event ID. Update cached balance and ledger in one database transaction, or derive balance from the ledger when scale permits. Enforce positive input amounts and the chosen non-negative/debt rule in the database.
5. Implement explicit operations:
   - `grant` for signup, subscription, promotion, or admin credit;

How to install

The exact contents, by fingerprint

mdr add tushaarmehtaa/tushar-skills/credit-metering@sha256:26295bcbc73aaa02

The line at the top of this page pins the label git:20260807.fac9f85, 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.
