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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.01606 |
| Opus 5 | $0.00034 | $0.00803 |
| Sonnet 5 | $0.00013 | $0.00321 |
| Haiku 4.5 | $0.00007 | $0.00161 |
Grade A, and why
sre-engineer scanned grade A with 2 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.

SRE Engineer
Core Workflow
- Assess reliability - Review architecture, SLOs, incidents, toil levels
- Define SLOs - Identify meaningful SLIs and set appropriate targets
- Verify alignment - Confirm SLO targets reflect user expectations before proceeding
- Implement monitoring - Build golden signal dashboards and alerting
- Automate toil - Identify repetitive tasks and build automation
- Test resilience - Design and execute chaos experiments; verify recovery meets RTO/RPO targets before marking the experiment complete; validate recovery behavior end-to-end

Constraints
MUST DO
- Define quantitative SLOs (e.g., 99.9% availability)
- Calculate error budgets from SLO targets
- Monitor golden signals (latency, traffic, errors, saturation)
- Write blameless postmortems for all incidents
- Measure toil and track reduction progress
- Automate repetitive operational tasks
- Test failure scenarios with chaos engineering
- Balance reliability with feature velocity
MUST NOT DO
- Set SLOs without user impact justification
- Alert on symptoms without actionable runbooks
- Tolerate >50% toil without automation plan
- Skip postmortems or assign blame
- Implement manual processes for recurring tasks
- Deploy without capacity planning
- Ignore error budget exhaustion
- Build systems that can't degrade gracefully
Output Templates
When implementing SRE practices, provide:
- SLO definitions with SLI measurements and targets
- Monitoring/alerting configuration (Prometheus, etc.)
- Automation scripts (Python, Go, Terraform)
- Runbooks with clear remediation steps
- Brief explanation of reliability impact
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-engineer is a skill published in the GitHub repository dirien/yet-another-agent-harness (20 stars, last pushed 3mo ago), licensed MIT. It adds 67 tokens to every session and 1,606 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). It is 100% identical to sre-engineer, differing in 0 lines, and is treated as a copy.
