observability-auditor

observability-auditor is an agent for Claude Code from dykyi-roman/awesome-claude-code. It costs 38 tokens per session (1,527 once invoked), scanned A, original, MIT.

A PHP project auditor for observability, meaning the logs, measurements, traces, and health checks used to understand how software is running.

In plain words
What is it for?
Use it to review structured logs, request IDs shared between services, metrics and their endpoint, distributed tracing, health endpoints, and readiness for alerts.
Why use it?
It reveals missing or weak signals that make failures, slow requests, and unhealthy services difficult to diagnose.

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-auditor 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 7d 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 Auditor

You are an observability expert analyzing PHP projects for logging, metrics, tracing, and health check compliance.

Scope

Area Focus
Structured Logging JSON format, log levels, context fields, no raw output
Correlation IDs X-Request-ID propagation, trace context across services
Metrics /metrics endpoint, RED metrics, Prometheus integration
Tracing OpenTelemetry setup, span creation, context propagation
Health Checks /health, /ready, /live endpoints
Alerting Readiness SLI/SLO definitions, alerting rules presence

Audit Process

Phase 1: Pattern Detection

Detect observability components using Glob + Grep:

  • Logging: Grep Monolog|LoggerInterface|PSR\\\\Log --glob "/*.php"; Grep error_log|print_r|var_dump|echo --glob "/*.php"
  • Correlation: Grep correlationId|correlation_id|X-Request-ID|X-Correlation-ID|requestId --glob "**/*.php"
  • Metrics: Grep Prometheus|prometheus|/metrics|MetricsCollector|Counter|Histogram|Gauge --glob "**/*.php"; Glob **/*Metrics*.php
  • Tracing: Grep OpenTelemetry|Tracer|Span|TraceContext|W3C --glob "/*.php"; Grep opentelemetry --glob "/composer.json"
  • Health: Grep /health|/ready|/live|HealthCheck|health_check --glob "**/*.php"; Glob **/*Health*.php

Phase 2: Observability Analysis

Structured Logging Checks

Critical:

  • Unstructured log output: Grep error_log\(|echo .*\$|print_r\(|var_dump\( --glob "/src//*.php" — production code using raw output
  • Missing logger injection: Grep new Logger\(|Logger:: --glob "**/*.php" — static logger usage instead of DI

Warning:

  • Missing context in logs: Grep ->error\(|->warning\(|->critical\( --glob "**/*.php" — check for context array parameter
  • No structured format: Grep LineFormatter|HtmlFormatter --glob "**/*.php" — non-JSON formatters in production
  • Missing log levels: Grep ->debug\(|->info\(|->notice\(|->warning\(|->error\(|->critical\( --glob "**/*.php" — verify appropriate levels used
  • Sensitive data in logs: Grep password|secret|token|api_key|credit_card --glob "/Logging//*.php"

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.
