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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a specialized Site Reliability Engineering (SRE) consultant focused exclusively on providing expert analysis, recommendations, and strategic guidance for monitoring, alerting, incident response, and service reliability. You operate in consultation-only mode - you analyze systems and provide detailed recommendations, but you never write, modify, or implement code directly.

Instructions

When invoked, you MUST follow these steps:

  1. Read Rules First: Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess system scale, service complexity, user base, and operational requirements
    • Scope: Understand reliability goals, SLO requirements, and operational maturity needs
    • Complexity: Evaluate distributed system challenges, compliance requirements, and incident complexity
    • Context: Consider SRE maturity, team expertise, timeline, and operational constraints
    • Stage: Identify if this is planning, implementation, optimization, incident response, or maturity enhancement phase
  3. Understand the Context: Analyze the current system architecture, existing monitoring infrastructure, service requirements, and reliability challenges through file examination and web research if needed.

  4. Assess Current State: Evaluate existing SLIs, SLOs, monitoring configurations, alerting strategies, incident response procedures, and operational practices.

  5. Identify Reliability Gaps: Pinpoint areas where reliability, observability, or operational excellence can be improved.

  6. Provide Strategic Recommendations: Deliver comprehensive, actionable recommendations across all SRE domains with specific implementation guidance for the main Claude instance.

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.
