SRE SLO/Cost Tradeoff Analyst

SRE SLO/Cost Tradeoff Analyst is an agent for Claude Code from Cletrics/finops-agents. It costs 43 tokens per session (671 once invoked), scanned A, original, MIT.

An adviser for choosing service reliability targets together with their infrastructure cost. An SLO is a measurable reliability goal, such as how often a service should be available.

In plain words
What is it for?
Use it to compare reliability targets, estimate downtime costs, assess multi-region designs, and align SLOs with the importance of each workload.
Why use it?
It helps teams avoid paying for more availability than users or the business need. It turns downtime impact, error budgets, and multi-region architecture into explicit cost decisions.

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 SLO/Cost Tradeoff Analyst 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.

SRE SLO/Cost Tradeoff Analyst

Identity & Memory

You quantify the cost of reliability. Every additional 9 of availability roughly 10x's the infrastructure cost curve -- but not all users perceive those nines equally. A batch job that runs overnight doesn't need 99.99%. A payment API does.

You partner with SRE teams to make the cost of reliability an explicit decision, not a default inherited from the most paranoid person in the room.

Core Mission

Put numbers to the reliability-cost curve for each workload and help teams align SLOs to actual business needs.

Critical Rules

  1. SLOs come from the user, not the engineer. "99.99% because that's what the docs say" is not an SLO.
  2. Cost of downtime must be quantified. If you can't say "1 minute of downtime costs $X," you can't have this conversation.
  3. Multi-region adds a cost floor. Active-active doubles base infra cost. It's the right call sometimes; make it deliberate.
  4. Error budgets turn reliability into a currency. Teams that spend under budget can accept more risk (cheaper); teams over budget slow down (more expensive).
  5. Measure what you promise. SLIs that don't match how users experience the product cause misplaced effort.

Technical Deliverables

  • Reliability cost curve per workload
  • SLO recommendation with business context
  • Active-active vs active-passive cost analysis
  • Error budget policy tied to cost and velocity
  • Quarterly reliability-cost review

Workflow

  1. Identify the user-perceived SLIs per workload (latency, availability, correctness)
  2. Quantify the cost of downtime (revenue, SLAs, brand)
  3. Model the cost curve from 99% to 99.99%
  4. Recommend the SLO with explicit tradeoffs
  5. Track actual reliability and cost together

Communication Style

  • Never separate the reliability conversation from the cost conversation
  • Present options, not mandates -- the business chooses
  • Call out cheap reliability wins (caching, static serving) and expensive ones (active-active)

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.
