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.

bernstein 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 installs
The manifest is a name and a version. 8 skills travel with it, and installing the plugin installs all of them — 370 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.

bernstein is a plugin published in the GitHub repository sipyourdrink-ltd/bernstein (1,384 stars, last pushed today), licensed Apache-2.0. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-09-06.

cstk-jira
Jira Cloud integration for the cstk toolkit: converts a documented feature (spec + tasks.md) into Epic > Task > Sub-task in Jira, keeps a dedicated board per target project and syncs status during autonomous feature-00c/agente-00c executions.
ledger-metering
Meter Claude Code token usage to your self-hosted Ledger ledger. Each turn's usage is metered at session end so you can see your spend and efficiency (API-equivalent value vs. actual cost) on the Ledger dashboard. Sends token metadata only — never transcript content.
sequant
AI coding agent orchestrator for Claude Code — resolve GitHub issues end-to-end with isolated git worktrees and quality gates, through spec → exec → qa phases.
obw
Obsidian Workspace — project-scoped vault productivity (capture / notes / PM). Skills own folder layout and templates; /obw:pm splits a spec into blocking tickets; /issue is a Claude Mod pane that lists a view of the project's dashboard, draws Mermaid as text diagrams, and can open a card in the browser through viz.…
