Use when a backend service must authenticate callers or enforce access. Verifies OIDC JWTs against JWKS, adds BFF session cookies for browsers, puts authorization in service-layer policies, denies by default and scopes every query to the tenant (Hono, Go, FastAPI).
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
# Set Up Backend Auth The service is an OIDC **resource server**: it verifies tokens, it does not log users in. Rules and rationale: [auth-patterns.md](auth-patterns.md). Code for each track: [auth-tracks.md](auth-tracks.md). Baseline: [security-baseline.md](../../core/_shared/security-baseline.md) rules 3 and 10. Seam paths: [service-layout.md](../_shared/service-layout.md). Browser counterpart: [set-up-auth](../../frontend/set-up-auth/SKILL.md) (no tokens in `localStorage`). ## 1. Audit (change nothing) ```bash cat .claude/stack-profile.md ~/.claude/stack-profile.md 2>/dev/null # backend.track, database, tests.layout, observability ls src/platform/auth.ts internal/platform/auth src/*/platform/auth.py 2>/dev/null grep -rnE "jsonwebtoken|python-jose|jwt\.decode|golang-jwt|go-oidc|PyJWT|jose|authlib" package.json go.mod pyproject.toml 2>/dev/null grep -rnE "tenant_id|tenantId|TenantID" --include=*.ts --include=*.go --include=*.py -l . 2>/dev/null | head grep -rnE "(isAdmin|is_admin|role ==)" --include=*.ts --include=*.go --include=*.py . 2>/dev/null | head # checks living in handlers ``` …

How to install
mdr add velimirmueller/claude-development-skills/set-up-backend-auth@sha256:97a71a62b85b13f8The line at the top of this page pins the label git:20261009.d042141, 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.
