Monitoring Setup Guide
Design observability stacks with Prometheus, Grafana, and SLO-aligned alerts
What You Can Do
You can design end-to-end observability architectures for cloud-native applications by defining golden signals (latency, traffic, errors, saturation) per service, generating production-ready Prometheus configurations and alert rules aligned to SLOs, and creating meaningful Grafana dashboards. This skill translates business requirements and SLOs into measurable observability coverage with runbook linkage and thresholds that reduce alert fatigue.
Features
Identifies and quantifies latency, traffic, error rate, and saturation metrics specific to each service
Converts Service Level Objectives into Prometheus alert rules with appropriate thresholds and severity levels
Generates scrape configs, recording rules, and metric relabeling strategies for multi-service environments
Structures dashboards with layered views (overview, service detail, dependency tracing) for different audience roles
Creates escalation policies and runbook linkage so incidents trigger appropriate responses
Audits existing monitoring against application topology to identify blind spots and redundancy
Maps distributed tracing requirements and log aggregation strategies across service boundaries
Designs isolation and billing-aware metrics for shared infrastructure and multi-team environments
Example Output
Example 1: Payment Service Golden Signals
Latency: p99 < 500ms (alert > 750ms)
Traffic: 100 req/sec nominal (alert < 20 req/sec)
Error Rate: < 0.1% (alert > 0.5%)
Saturation: CPU < 70% (alert > 85%)
Example 2: Prometheus Alert Rule
alert: PaymentServiceHighLatency
expr: histogram_quantile(0.99, payment_request_duration_seconds_bucket) > 0.75
for: 5m
annotations:
summary: "Payment service p99 latency > 750ms"
runbook: "https://wiki.internal/runbooks/payment-latency"
Example 3: Grafana Dashboard Section
- Service health status card (traffic, error rate, availability %)
- Latency distribution (p50, p95, p99)
- Resource usage gauges (CPU, memory, disk)
- Dependency health heatmap (downstream services)

Rapidly analyze production incidents by correlating observability signals—logs, metrics, traces, and events—to identify the true root cause instead of symptoms. You'll reconstruct incident timelines, quantify impact scope, and generate both immediate remediation steps and long-term prevention measures.
Claude analyzes your code diffs and generates standardized commit messages that follow the Conventional Commits specification. The skill automatically determines the correct commit type, scope, and description based on the changes you've made, ensuring your messages are parseable by automation tools while remaining human-readable for code reviewers.
You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.
Transform schema and data changes into production-ready migration packages that protect data integrity and minimize downtime. You can handle column additions, renames, type conversions, and backfills using proven patterns like expand-contract and shadow tables. The skill generates explicit rollback scripts, validation checklists, and phased execution plans that keep applications stable throughout the migration.
You can design end-to-end NGS pipelines tailored to your experiment type (WGS, WES, RNA-seq, targeted), troubleshoot pipeline failures by analyzing QC metrics and logs, and optimize performance by fine-tuning parameters and identifying bottlenecks. This skill handles the full workflow from raw sequencing data quality assessment through variant interpretation and annotation.
You can analyze any NoSQL query—whether MongoDB, DynamoDB, Cassandra, or Firestore—to identify performance bottlenecks, missing indexes, and inefficient data access patterns. You'll receive structured recommendations with before/after comparisons, cost estimates, and refactored queries that dramatically improve performance and reduce database costs.
You get a comprehensive analysis of your embedded system design covering memory footprint, power consumption, real-time performance, and hardware-software tradeoffs. Claude identifies architectural bottlenecks, suggests optimization strategies, and validates your design against reliability and performance requirements specific to embedded constraints.
You can accelerate your entire antenna design workflow—from initial concept to optimized specifications—by leveraging Claude's knowledge of electromagnetic theory, antenna types, and design trade-offs. Claude helps you parameterize designs, identify optimal configurations for your frequency band and application, and prepare detailed briefs for simulation and manufacturing. You'll generate design reviews, impedance-matching solutions, and validation checklists without context-switching to multiple tools.
