Version Command (/version)

Purpose

Display local and global installation versions, check for the latest updates from GitHub, and provide upgrade recommendations.

Execution Flow

1. Local Version Check: Read version information from ./.claude/version.json if it exists.
2. Global Version Check: Read version information from ~/.claude/version.json if it exists.
3. Fetch Remote Versions: Use GitHub API to get the latest stable release tag and the latest commit hash from the main branch.
4. Compare & Suggest: Compare installed versions with the latest remote versions and provide upgrade suggestions if applicable.

Step 1: Check Local Version

Check if local version.json exists

bash(test -f ./.claude/version.json && echo "found" || echo "not_found")

Read local version (if exists)

bash(cat ./.claude/version.json)

Extract version with jq (preferred)

bash(cat ./.claude/version.json | grep -o '"version": *"[^"]*"' | cut -d'"' -f4)

Extract installation date

bash(cat ./.claude/version.json | grep -o '"installation_date_utc": *"[^"]*"' | cut -d'"' -f4)

Output Format:

Local Version: 3.2.1
Installed: 2025-10-03T12:00:00Z

Step 2: Check Global Version

Check if global version.json exists

bash(test -f ~/.claude/version.json && echo "found" || echo "not_found")

Read global version

bash(cat ~/.claude/version.json)

Extract version

bash(cat ~/.claude/version.json | grep -o '"version": *"[^"]*"' | cut -d'"' -f4)

Extract installation date

bash(cat ~/.claude/version.json | grep -o '"installation_date_utc": *"[^"]*"' | cut -d'"' -f4)

Output Format:

Global Version: 3.2.1
Installed: 2025-10-03T12:00:00Z

Step 3: Fetch Latest Stable Release

Call GitHub API for latest release (with timeout)

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/releases/latest" 2>/dev/null, timeout: 30000)

Extract tag name (version)

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/releases/latest" 2>/dev/null | grep -o '"tag_name": *"[^"]*"' | head -1 | cut -d'"' -f4, timeout: 30000)

Extract release name

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/releases/latest" 2>/dev/null | grep -o '"name": *"[^"]*"' | head -1 | cut -d'"' -f4, timeout: 30000)

Extract published date

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/releases/latest" 2>/dev/null | grep -o '"published_at": *"[^"]*"' | cut -d'"' -f4, timeout: 30000)

Output Format:

Latest Stable: v3.2.2
Release: v3.2.2: Independent Test-Gen Workflow with Cross-Session Context
Published: 2025-10-03T04:10:08Z

Step 4: Fetch Latest Main Branch

Call GitHub API for latest commit on main (with timeout)

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/commits/main" 2>/dev/null, timeout: 30000)

Extract commit SHA (short)

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/commits/main" 2>/dev/null | grep -o '"sha": *"[^"]*"' | head -1 | cut -d'"' -f4 | cut -c1-7, timeout: 30000)

Extract commit message (first line only)

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/commits/main" 2>/dev/null | grep '"message":' | cut -d'"' -f4 | cut -d'\' -f1, timeout: 30000)

Extract commit date

bash(curl -fsSL "https://api.github.com/repos/catlog22/Claude-Code-Workflow/commits/main" 2>/dev/null | grep -o '"date": *"[^"]*"' | head -1 | cut -d'"' -f4, timeout: 30000)

Output Format:

Latest Dev: a03415b
Message: feat: Add version tracking and upgrade check system
Date: 2025-10-03T04:46:44Z

Step 5: Compare Versions and Suggest Upgrade

Normalize versions (remove 'v' prefix)

bash(echo "v3.2.1" | sed 's/^v//')

Compare two versions

bash(printf "%s\n%s" "3.2.1" "3.2.2" | sort -V | tail -n 1)

Check if versions are equal

# If equal: Up to date
# If remote newer: Upgrade available
# If local newer: Development version

Output Scenarios:

Scenario 1: Up to date

You are on the latest stable version (3.2.1)

Scenario 2: Upgrade available

A newer stable version is available: v3.2.2
Your version: 3.2.1

To upgrade:
PowerShell: iex (iwr -useb https://raw.githubusercontent.com/catlog22/Claude-Code-Workflow/main/install-remote.ps1)
Bash: bash <(curl -fsSL https://raw.githubusercontent.com/catlog22/Claude-Code-Workflow/main/install-remote.sh)

Scenario 3: Development version

You are running a development version (3.4.0-dev)
This is newer than the latest stable release (v3.3.0)

Error Handling

No installation found

WARNING: Claude Code Workflow not installed
Install using:
PowerShell: iex (iwr -useb https://raw.githubusercontent.com/catlog22/Claude-Code-Workflow/main/install-remote.ps1)

Network error

ERROR: Could not fetch latest version from GitHub
Check your network connection

Invalid version.json

ERROR: version.json is invalid or corrupted

Design Notes

• Uses simple, direct bash commands instead of complex functions
• Each step is independent and can be executed separately
• Fallback to grep/sed for JSON parsing (no jq dependency required)
• Network calls use curl with error suppression and 30-second timeout
• Version comparison uses sort -V for accurate semantic versioning
• Use /commits/main API instead of /branches/main for more reliable commit info
• Extract first line of commit message using cut -d'\' -f1 to handle JSON escape sequences

API Endpoints

GitHub API Used

• Latest Release: https://api.github.com/repos/catlog22/Claude-Code-Workflow/releases/latest
  • Fields: tag_name, name, published_at
• Latest Commit: https://api.github.com/repos/catlog22/Claude-Code-Workflow/commits/main
  • Fields: sha, commit.message, commit.author.date

Timeout Configuration

All network calls should use timeout: 30000 (30 seconds) to handle slow connections.
