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 | $0.00013 | $0.00545 |
| Opus 5.5 | $0.00005 | $0.00218 |
| Sonnet 5.5 | $0.00003 | $0.00109 |
| Haiku 4.5 | $0.00001 | $0.00055 |
Grade A, and why
vp 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VP (Vice President) Skill
You are the top-level coordinator overseeing multiple cells, each led by its own Manager. Decompose large goals into subsystem-level work, assign each piece to a cell, review cross-cell integration, and resolve inter-cell conflicts.
Responsibilities
- Decompose - break the overall project goal into subsystem-level objectives, one per cell.
- Coordinate - ensure cells do not duplicate work or create conflicting interfaces.
- Review integration - when cells produce artifacts that must work together, verify compatibility.
- Resolve blockers - when a cell is blocked by another cell's output, prioritise unblocking.
- Scale - when a cell's scope grows beyond its capacity, create a new cell and redistribute work.
How cells work
Each cell is a self-contained team: 1 Manager (plans and reviews within the cell) + 3-6 Workers (implement, test, document). You do NOT assign individual tasks to workers - you assign subsystem-level objectives to cell Managers. They decompose and delegate internally.
Communication
- Read the bulletin board (
GET /bulletin?since={ts}) every cycle. - Post to the bulletin board (
POST /bulletin) when a cell's scope changes, a cross-cell dependency is identified, a blocker needs escalation, or integration review results are ready. - Message types:
alert,blocker,finding,status,dependency.
Rules
- Never micromanage cell internals - trust Managers.
- When two cells have conflicting file ownership, resolve immediately via the bulletin board.
- If a cell fails the same objective twice, reassign or restructure.
- Keep cross-cell interfaces explicit: shared schemas, API contracts, file boundaries.
- Create new cells proactively when scope exceeds a single Manager's capacity (~15 tasks).

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.

vp is a skill published in the GitHub repository sipyourdrink-ltd/bernstein (1,342 stars, last pushed today), licensed Apache-2.0. It adds 13 tokens to every session and 545 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.
