bernstein-plan

bernstein-plan is a skill for Cursor from sipyourdrink-ltd/bernstein. It costs 51 tokens per session (601 once invoked), scanned A, original, Apache-2.0.

A tool for breaking a complex coding task into ordered stages and smaller steps in Bernstein. It can describe which stages depend on earlier work and wait for approval before agents begin.

In plain words
What is it for?
Use it to plan features such as authentication, split work between stages, and review the execution plan.
Why use it?
It makes large tasks easier to review and coordinate before implementation starts.

About the project

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.

Token cost

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.

Security

Grade A, and why

bernstein-plan 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/plan.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bernstein Plan Mode

Create structured execution plans that get human approval before agents start.

When to Use

  • User describes a complex feature: "implement user authentication with OAuth"
  • User wants to break down a large task into stages
  • User says "plan this out" or "create a plan for..."
  • User wants to review what agents will do before they start

Instructions

Creating a plan

  1. Analyze the user's request and decompose it into stages and tasks.
  2. Write a plan YAML file using this structure:
name: "{descriptive plan name}"
description: "{what this plan achieves}"
stages:
  - name: foundation
    steps:
      - goal: "Create database models for user and session"
        role: backend
        scope: small
        complexity: low
      - goal: "Add migration scripts"
        role: backend
        scope: tiny

  - name: implementation
    depends_on: [foundation]
    steps:
      - goal: "Implement OAuth2 flow with Google provider"
        role: backend
        scope: medium
        complexity: medium
      - goal: "Create login/signup UI components"
        role: frontend
        scope: medium

  - name: verification
    depends_on: [implementation]
    steps:
      - goal: "Write integration tests for auth flow"
        role: qa
        scope: medium
      - goal: "Security review of token handling"
        role: security
        scope: small
  1. Save the plan to plans/{plan-name}.yaml in the project root.
  2. Tell the user to execute it: bernstein run plans/{plan-name}.yaml

Or submit via API

  1. Run scripts/plan.sh submit plans/{plan-name}.yaml to submit for approval.
  2. The plan enters pending state - use /bernstein-approve to review and approve.
  3. Once approved, planned tasks promote to open and agents start picking them up.

Reviewing plans

  1. Run scripts/plan.sh list to see all plans and their status.
  2. Show the plan with stages, dependencies, and estimated cost/time.

Tips

  • Keep stages to 2-5 tasks each
  • Use depends_on to enforce ordering (foundation before implementation)
  • Assign appropriate roles: backend, frontend, qa, security, devops, docs
  • Mark risky tasks with complexity: high - they'll get more capable models
  • Foundation stages should be tiny or small scope

Files

What ships with it

1 file 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.

Changes

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.
