# ChernyCode A template repository implementing Boris Cherny's productivity tips for AI-assisted coding with **Claude Code** and **Cursor**. Boris Cherny is the creator of Claude Code. This repo synthesizes his recommendations from two threads on how he and the Claude Code team use the tool, providing ready-to-use configurations for maximum productivity. ## What's Included | File/Directory | Purpose | Install To | |----------------|---------|------------| | `CLAUDE.md` | Project memory for Claude Code | Project root | | `AGENTS.md` | Agent instructions for Cursor | Project root | | `.cursor/skills/` | Project-specific Cursor skills | Project `.cursor/skills/` | | `claude_personal_skills/` | Personal Claude Code skills | `~/.claude/skills/` | | `claude_subagents/` | Claude Code subagent definitions | `~/.claude/agents/` | | `cursor_personal_skills/` | Personal Cursor skills | `~/.cursor/skills-cursor/` | | `cursor_subagents/` | Cursor subagent definitions | `~/.cursor/agents/` | ## Quick Start ### 1. Copy Project Files Copy these files to your project root: - `CLAUDE.md` - Edit for your project's context - `AGENTS.md` - Edit for your project's context - `.cursor/skills/` - Copy the skills directory ### 2. Install Personal Files Copy these from this repo to your home directory for use across all projects: ```bash # Create directories if they don't exist mkdir -p ~/.claude/skills ~/.claude/agents ~/.cursor/skills-cursor ~/.cursor/agents # Claude Code personal skills cp -r claude_personal_skills/* ~/.claude/skills/ # Claude Code subagents cp -r claude_subagents/* ~/.claude/agents/ # Cursor personal skills cp -r cursor_personal_skills/* ~/.cursor/skills/ # Cursor subagents cp -r cursor_subagents/* ~/.cursor/agents/ ``` ### 3. (Optional) Install Personal CLAUDE.md Create a personal memory file for all projects: ```bash # Copy the template (edit with your preferences) cp CLAUDE.md ~/.claude/CLAUDE.md ``` ## Key Concepts ### Memory Files (CLAUDE.md / AGENTS.md) These files provide persistent context that the AI reads at the start of every session: - **Project-level** (`./CLAUDE.md`, `./AGENTS.md`): Shared with your team via git - **Personal** (`~/.claude/CLAUDE.md`): Your preferences across all projects - **Local** (`./CLAUDE.local.md`): Personal project settings, gitignored **Best Practice**: After every correction, say: > "Update CLAUDE.md so you don't make that mistake again" Claude is excellent at writing rules for itself. ### Skills Skills are reusable workflows you can invoke with `/skill-name`: | Skill | Description | |-------|-------------| | `/commit-push-pr` | Commit, push, and create a PR | | `/techdebt` | Find and fix technical debt | | `/code-simplifier` | Clean up code after changes | | `/code-style` | Python code style guidelines | | `/testing` | pytest conventions | | `/git-workflow` | Git and commit conventions | | `/llm-development` | LLM/ML best practices | ### Subagents Subagents run specialized tasks in their own context window, enabling parallel execution and context isolation: | Agent | Description | |-------|-------------| | `code-reviewer` | Review code as a senior engineer (readonly) | | `test-writer` | Write comprehensive tests (proactive) | | `doc-generator` | Generate documentation | | `verifier` | Validate completed work (fast model) | Use subagents by: - Slash command: `/code-reviewer review my changes` - Natural language: "use the verifier agent to confirm the feature is complete" ## Boris Cherny's Top Tips ### 1. Start in Plan Mode For complex tasks, start in Plan mode: - **Cursor**: Toggle plan mode in the UI - **Claude Code**: Press `Shift+Tab` twice Pour your energy into the plan. A good plan lets Claude one-shot the implementation. ### 2. Work in Parallel Run multiple Claude sessions simultaneously: - Use git worktrees for parallel branches - Run 3-5 sessions on different tasks - Hand off sessions between terminal and web ### 3. Create Skills for Repeated Workflows If you do something more than once a day, make it a skill: ```bash # Create a new skill mkdir -p ~/.claude/skills/my-skill cat > ~/.claude/skills/my-skill/SKILL.md << 'EOF' --- name: my-skill description: What this skill does --- # My Skill Instructions for Claude... EOF ``` ### 4. Give Claude Verification Methods The most important tip: **Give Claude a way to verify its work.** - Run tests after changes - Use browser testing for UI - Check linter output - Verify with `git diff` ### 5. Continuously Update CLAUDE.md After every mistake or correction: > "Update CLAUDE.md so you don't make that mistake again" Over time, Claude's error rate will measurably drop. ### 6. Use Voice Dictation On macOS, press `fn` twice to dictate. You speak 3x faster than you type, and your prompts become more detailed. ## Repository Structure ``` ChernyCode/ ├── README.md ├── CLAUDE.md # Project memory for Claude Code ├── AGENTS.md # Agent instructions for Cursor ├── threads.md # Source material from Boris Cherny │ ├── .cursor/skills/ # Project-specific Cursor skills │ ├── code-style/SKILL.md │ ├── testing/SKILL.md │ ├── git-workflow/SKILL.md │ └── llm-development/SKILL.md │ ├── claude_personal_skills/ # Install to ~/.claude/skills/ │ ├── commit-push-pr/SKILL.md │ ├── techdebt/SKILL.md │ └── code-simplifier/SKILL.md │ ├── claude_subagents/ # Install to ~/.claude/agents/ │ ├── code-reviewer.md │ ├── test-writer.md │ └── doc-generator.md │ ├── cursor_personal_skills/ # Install to ~/.cursor/skills-cursor/ │ ├── commit-push-pr/SKILL.md │ ├── techdebt/SKILL.md │ └── code-simplifier/SKILL.md │ ├── cursor_subagents/ # Install to ~/.cursor/agents/ │ ├── code-reviewer.md │ ├── doc-generator.md │ ├── test-writer.md │ └── verifier.md │ └── .cursor/agents/ # Project-specific Cursor subagents ├── code-reviewer.md ├── doc-generator.md ├── test-writer.md └── verifier.md ``` ## Target Installation Structure After installation, your home directory will have: ``` ~/.claude/ ├── CLAUDE.md # Personal memory (all projects) ├── skills/ │ ├── commit-push-pr/SKILL.md │ ├── techdebt/SKILL.md │ └── code-simplifier/SKILL.md └── agents/ ├── code-reviewer.md ├── test-writer.md └── doc-generator.md ~/.cursor/ ├── skills-cursor/ │ ├── commit-push-pr/SKILL.md │ ├── techdebt/SKILL.md │ └── code-simplifier/SKILL.md └── agents/ ├── code-reviewer.md ├── doc-generator.md ├── test-writer.md └── verifier.md ``` ## Customization ### Edit Project Memory Update `CLAUDE.md` and `AGENTS.md` with: - Your project's purpose and architecture - Coding standards specific to your team - Common commands and workflows - Known pitfalls (add these as you encounter them) ### Create New Skills 1. Create a directory: `~/.claude/skills/my-skill/` 2. Add `SKILL.md` with frontmatter and instructions 3. Invoke with `/my-skill` ### Create New Subagents **For Claude Code:** 1. Create a file: `~/.claude/agents/my-agent.md` 2. Add frontmatter with `name`, `description`, `allowed-tools` 3. Add the agent's system prompt 4. Use by asking Claude to "use the my-agent agent" **For Cursor:** 1. Create a file: `.cursor/agents/my-agent.md` (project) or `~/.cursor/agents/my-agent.md` (global) 2. Add YAML frontmatter with: - `name`: Unique identifier (lowercase, hyphens) - `description`: When to use (Agent reads this for auto-delegation) - `model`: `fast`, `inherit`, or specific model ID - `readonly`: Set to `true` for read-only operations - `is_background`: Set to `true` for background execution 3. Add the agent's prompt below the frontmatter 4. Invoke with `/my-agent` or mention naturally in your prompt ## Sources Based on Boris Cherny's threads: - [How I use Claude Code](https://readwise.io/reader/shared/01kgcamtex6zews0fvz94a8qg4) - [Tips from the Claude Code team](https://readwise.io/reader/shared/01kgb6njjekq2hpxc0ycymbrcg/) ## License MIT
