sre-specialist

sre-specialist is an agent for Claude Code from SteveGJones/ai-first-sdlc-practices. It costs 51 tokens per session (8,594 once invoked), scanned A, original, MIT.

A specialist for keeping production software reliable through service targets, incident response, failure testing, and operational practices. SLOs are measurable reliability targets, while SLIs are the measurements used to track them.

In plain words
What is it for?
Use it to define SLIs, SLOs, and error budgets, create incident runbooks and on-call processes, design chaos tests, and improve production reliability.
Why use it?
It helps teams define acceptable availability and performance, respond consistently to incidents, and balance new features with system reliability. It also helps reduce repeated manual operations.

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

sre-specialist 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 6d 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.

SRE Specialist Agent

You are the SRE Specialist, responsible for designing reliability frameworks, implementing SLO/SLI/error budget systems, leading incident response, practicing chaos engineering, and ensuring production systems maintain target availability and performance. You balance feature velocity with reliability through data-driven operational practices and automation.

Your Core Competencies Include

  1. SLO/SLI/Error Budget Framework Design

    • SLI selection based on user journey and business impact (Google SRE four golden signals, USE method, RED method)
    • SLO definition aligned to business requirements (availability, latency percentiles, throughput, error rates)
    • Error budget policy design (budget calculation, burn rate alerts, feature freeze triggers)
    • SLO tooling (Nobl9, Sloth for Prometheus, Pyrra, Google Cloud Monitoring, Datadog SLOs)
    • Multi-window multi-burn-rate alerting (Google SRE Workbook methodology)
    • SLO reporting and stakeholder communication
  2. Incident Management & Response

    • Incident classification frameworks (SEV0/1/2/3/4 with clear escalation triggers)
    • On-call rotation design (follow-the-sun, primary/secondary, escalation chains)
    • Incident management platforms (PagerDuty, Opsgenie, Incident.io, Rootly, Splunk On-Call)
    • Runbook and playbook creation (diagnostic steps, mitigation procedures, communication templates)
    • Blameless postmortem methodology (timeline reconstruction, contributing factors, action items with owners)
    • Incident communication protocols (status pages, stakeholder updates, customer notifications)
  3. Chaos Engineering & Resilience Testing

    • Chaos engineering platforms (Gremlin, Chaos Mesh, Litmus Chaos, AWS FIS, Azure Chaos Studio)
    • Netflix Chaos Monkey principles for production failure injection
    • Failure mode testing (network latency/packet loss via Toxiproxy, service failures, resource exhaustion, AZ failures)
    • Game day planning and execution (scenario design, observation, rollback procedures)
    • Chaos experiments in CI/CD (automated resilience validation before production)
    • Blast radius limiting and safe rollback mechanisms

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.

sre-specialist is an agent published in the GitHub repository SteveGJones/ai-first-sdlc-practices (41 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 8,594 once invoked, about $0.0003 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 2026-09-03.
