Expert guidance for SigNoz, the open-source observability platform that provides traces, metrics, and logs in a single UI. Built natively on OpenTelemetry, SigNoz is a self-hosted alternative to Datadog and New Relic. Helps developers set up distributed tracing, application performance monitoring, log management, and custom dashboards.
You are an expert in Traceloop and its OpenLLMetry SDK, the open-source observability framework that extends OpenTelemetry for LLM applications. You help developers instrument AI pipelines with automatic tracing for OpenAI, Anthropic, Cohere, LangChain, LlamaIndex, vector databases, and frameworks — exporting to any OpenTelemetry-compatible backend (Grafana Tempo, Jaeger, Datadog, Honeycomb, Traceloop Cloud).
Deploy and use Jaeger for distributed tracing across microservices. Use when a user needs to set up trace collection, instrument applications with OpenTelemetry, analyze trace data to find latency bottlenecks, or configure Jaeger storage backends and sampling strategies.
You are an expert in Langtrace, the open-source observability platform for LLM applications built on OpenTelemetry. You help developers trace LLM calls, RAG pipelines, agent tool use, and chain executions with automatic instrumentation for OpenAI, Anthropic, LangChain, LlamaIndex, and 20+ providers — providing cost tracking, latency analysis, token usage, and quality evaluation in a self-hostable dashboard.
Loki is a horizontally scalable log aggregation system built by Grafana Labs. Unlike traditional log platforms that index the full text of every log line, Loki indexes only metadata labels, making it significantly cheaper to operate. It integrates natively with Grafana for querying and visualization, and uses LogQL — a query language inspired by PromQL — to filter, parse, and aggregate log streams.
Set up and manage New Relic for full-stack observability including APM, browser monitoring, infrastructure monitoring, and alerting. Use when a user needs to instrument applications, write NRQL queries, create dashboards, configure alert policies, or integrate New Relic with their deployment pipeline.
Set up end-to-end observability for microservices. Use when someone asks to "add tracing", "set up monitoring", "configure OpenTelemetry", "build Grafana dashboards", "distributed tracing", "structured logging", "metrics collection", or "debug production issues". Covers OpenTelemetry instrumentation, collector configuration, Grafana LGTM stack deployment, dashboard provisioning, and alert rules.
Deploy and configure VictoriaMetrics as a high-performance time-series database for metrics storage and querying. Use when a user needs a Prometheus-compatible long-term storage backend, wants to write MetricsQL queries, configure vmagent for metrics scraping, or set up VictoriaMetrics cluster mode for horizontal scaling.
Grafana is an open-source visualization and dashboarding platform that connects to dozens of data sources including Prometheus, PostgreSQL, ClickHouse, and Elasticsearch. It lets you build interactive dashboards with panels, set up alerting rules, and manage everything as code through JSON dashboard definitions and provisioning configuration.
Define success criteria and tracking setup for launch during PRD v0.9 Go-to-Market. Triggers on requests to define launch metrics, set up tracking, or when user asks "how do we measure launch success?", "launch KPIs", "tracking setup", "success criteria", "analytics", "launch goals". Outputs KPI- entries specialized for launch measurement.
Expert knowledge in quality assurance gates, code quality standards, and automated checks. Use when enforcing quality standards.
Approve a specification and export it to beads as an epic with tasks. Creates the epic, child tasks, dependencies, and agent assignment labels. Use after reviewing the spec from /start-discovery.
Define monitoring strategy, metrics collection, and alerting thresholds during PRD v0.8 Deployment & Ops. Triggers on requests to set up monitoring, define alerts, or when user asks "what should we monitor?", "alerting strategy", "observability", "metrics", "SLOs", "dashboards", "monitoring setup". Outputs MON- entries with monitoring rules and alert configurations.
Defines database performance monitoring strategy with slow query detection, resource usage alerts, query execution thresholds, and automated alerting. Use for "database monitoring", "performance alerts", "slow queries", or "DB metrics".
Creates SLO-based alerts and operational dashboards with key charts, alert thresholds, and runbook links. Use for "alerting", "dashboards", "SLO", or "monitoring".
Define release criteria, deployment environments, and rollback strategies during PRD v0.8 Deployment & Ops. Triggers on requests to plan releases, define deployment criteria, or when user asks "how do we deploy?", "release criteria", "deployment plan", "rollback strategy", "go-live checklist". Outputs DEP- entries with deployment steps and release criteria.
Run repo quality gates. Use when asked to run tests/lint/build/CI checks, or mentions "lint/typecheck/build/e2e/Playwright/CI" or "動作確認/テストして".
DevOps and infrastructure specialist for Rails applications. Use when setting up Docker, CI/CD pipelines, deployment configurations, monitoring, logging, or production optimizations. Covers GitHub Actions, Docker, Kubernetes, and cloud platforms.
Manages environment variables and secrets securely with encryption, rotation, and provider integration. Use when users request "secrets management", "environment variables", "API keys", "credentials storage", or "secret rotation".
Generates Kubernetes manifests including Deployments, Services, ConfigMaps, Secrets, Ingress, and HPA with best practices. Use when users request "Kubernetes setup", "K8s manifests", "deploy to Kubernetes", "container orchestration", or "K8s configuration".
Disable Kuma overnight autonomous mode and summarize what happened overnight.
