How It Works

Claude Code automatically recognizes any markdown file in your project's .claude/commands/ directory as a slash command. No installation or setup required - just add the file and start using it!

Command Structure

Each command file needs:

  • Title: # Command Name
  • Description: Brief overview of what the command does
  • Instructions: ## Instructions section with detailed steps

Example minimal command (my-command.md):

# My Custom Command

Performs a specific task in my project.

## Instructions

1. **First Step**
   - Do this thing
   - Check that thing

2. **Second Step**
   - Execute this action
   - Verify the result

Use it immediately with: /namespace:my-command

Using Commands

Commands are available as /namespace:command-name in Claude Code. Each command follows a structured workflow that Claude executes automatically, ensuring consistent and thorough results across different projects.

Example workflows:

  • /dev:code-review analyzes your entire codebase for quality, security, and performance
  • /project:create-feature dashboard plans, implements, and tests a new dashboard feature
  • /dev:fix-issue 123 systematically resolves GitHub issue #123 with testing
  • /simulation:business-scenario-explorer Evaluate market expansion into Europe models multiple business timelines and outcomes

Common Workflows

New Feature Development:

/dev:code-review                    # Assess current state
/project:create-feature user-dashboard  # Implement feature
/security:security-audit                 # Verify security

Bug Fixing:

/dev:fix-issue 456                  # Fix the specific issue
/dev:code-review                    # Verify fix quality

Code Maintenance:

/security:dependency-audit               # Check for outdated dependencies
/performance:performance-audit              # Identify bottlenecks
/dev:refactor-code legacy-module    # Improve problematic areas

Strategic Decision Making:

/simulation:constraint-modeler              # Map decision constraints
/simulation:business-scenario-explorer      # Explore multiple timelines
/simulation:decision-tree-explorer          # Optimize decision choices

  • Total Count Tracking: Maintains accurate count of total available commands
  • Description Extraction: Pulls descriptions directly from command files
  • Backup Safety: Creates backups before making changes

Release Process

This project uses automated releases powered by Conventional Commits. Every merge to the main branch triggers our release workflow which:

  1. Analyzes commits to determine version bump type
  2. Updates version automatically based on commit types
  3. Generates release notes from commit messages
  4. Creates GitHub releases with downloadable bundles
  5. Updates changelog with categorized changes

Version Bumping Rules

  • fix: commits → Patch release (1.0.0 → 1.0.1)
  • feat: commits → Minor release (1.0.0 → 1.1.0)
  • Breaking changes → Major release (1.0.0 → 2.0.0)

Making Releases

Releases happen automatically when you:

  1. Merge PRs with conventional commit titles
  2. Push directly to main with conventional commits

For details on contributing and commit formats, see CONTRIBUTING.md.

Requirements

  • Claude Code version 1.0 or later
  • Commands work with any programming language or framework
