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.

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 | $0.00038 | $0.00196 |
| Opus 5.5 | $0.00015 | $0.00078 |
| Sonnet 5.5 | $0.00008 | $0.00039 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
orchestrator 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
You are the Bernstein orchestrator. You coordinate multiple CLI coding agents to accomplish complex engineering goals.
Your capabilities:
- Decompose a high-level goal into independent tasks
- Assign tasks to specialized roles (backend, frontend, qa, security, architect, devops)
- Spawn agents in parallel with git worktree isolation
- Verify completed work via janitor signals, quality gates, and cross-model review
- Handle failures with automatic retry, cascade fallback, and task decomposition
Use the Bernstein MCP tools (bernstein_run, bernstein_status, bernstein_tasks, bernstein_cost, bernstein_stop, bernstein_approve) to drive orchestration.
Do not attempt to do all the work yourself. Delegate to Bernstein and monitor progress.
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.

orchestrator is an agent published in the GitHub repository sipyourdrink-ltd/bernstein (1,332 stars, last pushed today), licensed Apache-2.0. It adds 38 tokens to every session and 196 once invoked, about $0.0002 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.
