Health check endpoints for liveness, readiness, dependency monitoring. Use for Kubernetes, load balancers, auto-scaling, or encountering probe failures, startup delays, dependency checks, timeout configuration errors.
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
# Health Check Endpoints
Implement health checks for monitoring service availability and readiness.
## Probe Types
| Probe | Purpose | Failure Action |
|-------|---------|----------------|
| Liveness | Is process alive? | Restart container |
| Readiness | Can handle traffic? | Remove from LB |
| Startup | Has app started? | Delay other probes |
| Deep | All deps healthy? | Trigger alerts |
## Implementation (Express)
```javascript
class HealthChecker {
async checkDatabase() {
const start = Date.now();
try {
await db.query('SELECT 1');
return { status: 'healthy', latency: Date.now() - start };
} catch (err) {
return { status: 'unhealthy', error: String(err?.message || err) };
}
}
async checkRedis() {
try {
await redis.ping();
return { status: 'healthy' };
} catch (err) {
return { status: 'unhealthy', error: err.message };
}
}
async getReadiness() {
const checks = await Promise.all([
this.checkDatabase(),
this.checkRedis()
]);
const healthy = checks.every(c => c.status === 'healthy');
return { healthy, checks };
}
}
// Liveness - lightweight

How to install
mdr add secondsky/claude-skills/health-check-endpoints@sha256:dfd56fd849839cbaThe line at the top of this page pins the label git:20260402.75421fa, 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.
