Use when designing or reviewing recurring subscription lifecycle on Stripe Billing — plans/Prices, trials, proration, upgrades/downgrades, cancel/pause, Smart Retries dunning, metered usage, automatic tax, multi-currency, and the strategy choice between subscription vs perpetual and monthly vs annual.
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
# Subscription Billing ## Required Inputs | Input | Required | Use | |---|---|---| | Tenant, product, and lifecycle scope | yes | Bound the SaaS decision | | Current architecture, plans, policies, and constraints | yes | Preserve enforceable behaviour | | Production data or verified evidence | conditional | Validate thresholds and migrations | ## Capability and permission contract Default to read-only analysis. Change configuration, billing, identity, tenant data, infrastructure, or customer communications only with explicit authority, least-privilege credentials, tenant scope, rollback, and auditable approval. Never expose secrets or cross tenant boundaries. ## Degraded mode If production access, policy, telemetry, or authoritative records are unavailable, produce a labelled design or dry-run plan. Do not claim deployment, reconciliation, deletion, delivery, or measured outcomes; list missing evidence and verification. ## Decision rules | Condition | Action | Stop condition | |---|---|---| | Tenant isolation, money, identity, or deletion is affected | Require approval and rollback evidence | Scope or authority is ambiguous | …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/subscription-billing@sha256:93556e08bcc08217The line at the top of this page pins the label git:20260929.c29972d, 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.
