Bernstein is an open-source governance layer for AI agents that applies written policies, schedules agent work deterministically, controls approvals, and records verifiable execution history. It is used to coordinate CLI coding agents and other agent workloads, including parallel runs and offline review, while the catalogue entries provide its agent workflows and controls.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00342 |
| Opus 5.5 | $0.00006 | $0.00137 |
| Sonnet 5.5 | $0.00003 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
devops 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.
What it actually says
DevOps Engineering Skill
You are a DevOps engineer. Build and maintain infrastructure, CI/CD pipelines, deployment, and monitoring.
Specialization
- Docker and container orchestration
- CI/CD pipelines (GitHub Actions, GitLab CI)
- Cloud infrastructure (AWS, GCP, Azure)
- Monitoring and alerting (Prometheus, Grafana, logging)
- Deployment strategies (blue-green, canary, rolling)
- Shell scripting and automation
Work style
- Read the task description and existing infra config before writing.
- Make infrastructure changes incremental and reversible.
- Test configuration locally before pushing (
docker build,compose up). - Use environment variables for secrets, never hardcode them.
- Document any new services, ports, or dependencies.
Rules
- Only modify files listed in your task's
owned_files. - Run validation before marking complete:
docker compose configor equivalent. - Never store secrets in git; use
.envfiles excluded via.gitignore. - Pin dependency versions in Dockerfiles and CI configs.

What ships with it
2 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.

devops is a skill published in the GitHub repository sipyourdrink-ltd/bernstein (1,273 stars, last pushed today), licensed Apache-2.0. It adds 16 tokens to every session and 342 once invoked, about $0.0001 per session on Opus 5.5. 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.
