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 | $0.00045 | $0.00045 |
| Opus 5.5 | $0.00018 | $0.00018 |
| Sonnet 5.5 | $0.00009 | $0.00009 |
| Haiku 4.5 | $0.00005 | $0.00005 |
Grade A, and why
git-workflow 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
Default branch: main.
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.

git-workflow is a cursor rule published in the GitHub repository sipyourdrink-ltd/bernstein (1,260 stars, last pushed today), licensed Apache-2.0. It adds 45 tokens to every session, 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.
Other cursor rules, from other repositories
cursor_rules_sync_requirement
Load after editing any rule or command source: run setupcursorcopies immediately in same conversation; do not defer; verify sync succeeded before marking rule update complete.
cursor_rules_sync
Load when modifying rule/command sources: pre-commit runs setupcursorcopies when staged; edit source in docs/ or foundation only; do not use --no-verify to bypass.
gsd
You have access to the aura CLI. These commands are NOT optional. Use them as described below.
cursor_rules_editing
Load when editing rules or commands: edit source in docs/ or foundation/agentinstructions/, never .cursor/rules or .cursor/commands; run setupcursorcopies after editing.
