About Bernstein and /dev for Claude Code

In their own words, as submitted to SaaSHub.

Bernstein
/dev for Claude Code

Bernstein is an open-source alternative to commercial agent platforms. It orchestrates multiple AI coding agents working on the same repo in parallel - each isolated in its own git worktree so they never step on each other. The scheduler is pure deterministic Python (zero LLM tokens spent on...

  • Skill-based architecture
    The project organizes Claude Code capabilities into modular 'skills' that can be individually managed, making it easier to extend and customize Claude Code's functionality for specific development tasks.
  • Practical development focus
    The repository appears focused on practical developer workflows and skills, aiming to enhance Claude Code's usefulness for real-world software development scenarios rather than abstract capabilities.
  • Open source and community-driven
    Being hosted on GitHub as an open-source project allows developers to contribute, fork, and adapt the skills to their own needs, fostering community collaboration and improvement.
  • Structured skill definitions
    The project provides a structured way to define and document skills for Claude Code, which can help standardize how developers extend and share Claude Code capabilities.
  • Low barrier to entry
    The repository offers a relatively straightforward approach for developers to get started with enhancing Claude Code, without requiring deep expertise in AI or complex setup procedures.

Possible disadvantages

  • Limited maturity and adoption
    The project appears to be in early stages of development with limited community adoption, which means it may lack thorough testing, comprehensive documentation, and proven reliability in production environments.
  • Sparse documentation
    The repository lacks detailed documentation, tutorials, and usage examples, making it challenging for new users to understand how to effectively use and contribute to the project.
  • Uncertain maintenance
    As a relatively small and new project, there is no guarantee of long-term maintenance, regular updates, or timely bug fixes, which could be a risk for developers relying on it.
  • Limited skill coverage
    The current set of skills available in the repository is limited and may not cover many common development scenarios, requiring users to create their own skills from scratch for their specific needs.
  • Dependency on Claude Code ecosystem
    The project is tightly coupled to Claude Code's specific interface and behavior, meaning changes or updates to Claude Code could break compatibility and require significant rework of existing skills.

Questions & Answers

As answered by people managing Bernstein and /dev for Claude Code.

What makes your product unique?

Bernstein's answer

Bernstein is the only orchestrator that uses deterministic code for scheduling instead of an LLM. Every other multi-agent framework (CrewAI, AutoGen, LangGraph) burns tokens deciding what to assign where. Bernstein spends zero tokens on coordination - the Python scheduler makes auditable, reproducible decisions. It also isolates every agent in its own git worktree, so agents never stomp on each other's files.

Why should a person choose your product over its competitors?

Bernstein's answer

  • No SDK to learn — works with CLI agents you already have (Claude Code, Codex, Gemini CLI)
  • No vendor lock-in — mix models in the same run
  • Verified output — janitor checks tests, lint, and types before merging
  • Cost savings — contextual bandit router cuts costs ~23% by learning which cheap model handles which task type
  • Reproducible — same inputs produce same scheduling decisions

How would you describe the primary audience of your product?

Bernstein's answer

  • Solo devs who want to run 6+ agents in parallel on a 10-ticket backlog
  • Tech leads evaluating multi-agent workflows without committing to a vendor
  • Teams that already use AI coding agents daily and want to parallelize their workflow

What's the story behind your product?

Bernstein's answer

Named after Leonard Bernstein, the conductor. The idea came from trying to coordinate three AI coding agents on the same codebase and watching them destroy each other's work. The first version used an LLM to schedule the other LLMs - it was slow, expensive, and hallucinated priorities. Replacing it with deterministic Python was the breakthrough.

Which are the primary technologies used for building your product?

Bernstein's answer

  • Python 3.12+ with asyncio
  • Git worktrees for agent isolation
  • LinUCB contextual bandits for model routing
  • Textual for the TUI dashboard
  • Hatchling for packaging

Who are some of the biggest customers of your product?

Bernstein's answer

  • Individual developers using it for personal projects
  • Open-source maintainers orchestrating codebase-wide refactors
  • Early-stage startups using it for overnight CI-fix automation
