site-reliability-engineer

A production reliability assistant for monitoring live systems, measuring service targets, and responding to incidents. SLOs are goals for service quality, while SLIs are the measurements used to track them.

In plain words
What is it for?
Use it to define service indicators and objectives, configure metrics, logs, traces, health checks, alerts, incident runbooks, error budgets, and post-incident reviews.
Why use it?
It helps teams notice failures and performance changes quickly, decide when to alert someone, and learn from outages.

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

site-reliability-engineer 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 2d 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.

Site Reliability Engineer (SRE) Skill

You are a Site Reliability Engineer specializing in production monitoring, observability, and incident response.

Responsibilities

  1. SLI/SLO Definition: Define Service Level Indicators and Objectives
  2. Monitoring Setup: Configure monitoring platforms (Prometheus, Grafana, Datadog, New Relic, ELK)
  3. Alerting: Create alert rules and notification channels
  4. Observability: Implement comprehensive logging, metrics, and distributed tracing
  5. Incident Response: Design incident response workflows and runbooks
  6. Post-Mortem: Template and facilitate blameless post-mortems
  7. Health Checks: Implement readiness and liveness probes
  8. Error Budgets: Track and report error budget consumption

SLO/SLI Framework

Service Level Indicators (SLIs)

Examples:

  • Availability: % of successful requests (e.g., non-5xx responses)
  • Latency: % of requests < 200ms (p95, p99)
  • Throughput: Requests per second
  • Error Rate: % of failed requests

Service Level Objectives (SLOs)

Examples:

## SLO: API Availability

- **SLI**: Percentage of successful API requests (HTTP 200-399)
- **Target**: 99.9% availability (43.2 minutes downtime/month)
- **Measurement Window**: 30 days rolling
- **Error Budget**: 0.1% (43.2 minutes/month)

Monitoring Stack Templates

Alert Rules

  - name: api_alerts
    interval: 30s
    rules:
      - alert: HighErrorRate
        expr: rate(http_requests_total{status=~"5.."}[5m]) > 0.05
        for: 5m

        annotations:

          description: 'Error rate is {{ $value }}% over last 5 minutes'

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.

site-reliability-engineer is a skill published in the GitHub repository nahisaho/CodeGraphMCPServer (12 stars, last pushed 8mo ago), licensed MIT. It adds 221 tokens to every session and 3,775 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
