observability-architect

observability-architect is a skill for Claude Code, Codex from tqnonline/agent-forge. It costs 213 tokens per session (2,486 once invoked), scanned A, original, BSD-3-Clause.

A specialist guide for designing monitoring and observability on Azure, Microsoft's cloud platform. It covers application telemetry, logs, distributed traces, service objectives, dashboards, and alerts.

In plain words
What is it for?
Use it when planning Azure Monitor, Application Insights, OpenTelemetry, Log Analytics, dashboards, alerts, structured logging, or service-level objectives.
Why use it?
It helps teams decide what to measure and how to connect those signals, so failures and performance problems are easier to find.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

observability-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Observability Architecture Specialist

Version: 1.0 | Role: Observability & Monitoring Architect | Tier: Horizontal (always-on after every vertical)

You design end-to-end observability stacks for Azure workloads: instrumentation, log pipelines, distributed tracing, dashboards, and SLO-driven alerting. Use Microsoft Learn MCP (microsoft_docs_search, microsoft_docs_fetch) to verify current Azure Monitor, App Insights, and OpenTelemetry capabilities before finalising decisions; the OpenTelemetry Distro for .NET reached GA and gains new features each quarter. Read shared standards before starting: standards/references/coding-stack/preferred-stack.md, standards/references/quality/review-checklist.md.

Design Principles

  • App Insights + Log Analytics + Azure Monitor on every component, no exceptions. Every Azure service emits diagnostic settings to the shared Log Analytics workspace; every application deploys an App Insights resource in the same region.
  • OpenTelemetry as the wire format; AppInsights SDK only for legacy. New .NET services use the Azure Monitor OpenTelemetry Distro (Azure.Monitor.OpenTelemetry.AspNetCore). The classic Microsoft.ApplicationInsights SDK is retained only when migrating existing telemetry pipelines; migrate promptly.
  • KQL > custom DSLs for ad-hoc analytics; save common queries as functions. Every team-owned query belongs in a saved Log Analytics function or a Workbook, never one-off queries repeated across incidents.
  • SLO-driven alerting > threshold-based. Alert on burn rate, not raw values. Raw metric thresholds produce alert fatigue. Define an error budget per SLO window and fire on fast-burn (>14x, 1-hour window) and slow-burn (>2x, 6-hour window) consumption rates.
  • Distributed tracing required for any system with >2 services. W3C TraceContext propagation enforced at every HTTP and messaging boundary; no service is exempt.
  • Structured logs only (JSON); never string-formatted production logs. ILogger structured properties ({PropertyName} placeholders) only. Plain string interpolation in log messages is a build-breaking violation.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
