Perfect! Now let me update the change log to capture this final addition about machine detection and OS-specific command selection.

**2026-01-15 (Evening Update 3):**
- **CRITICAL ADDITION: Machine Detection & OS-Specific Command Selection**
  - Added 1 new specialized agent (total: 13 agents):
    13. Machine Detection Agent (identifies current machine, loads capabilities)
  - Added 1 new database table (total: 34 tables):
    - machines (technician's laptops/desktops with capabilities tracking)
  - Enhanced sessions table with machine_id tracking
  - Machine fingerprinting via SHA256(hostname|username|platform|home_dir)
  - Auto-detection on session start (hostname, whoami, platform)
  - Machine capabilities tracked:
    - VPN access per client, Docker, PowerShell version, SSH, Git
    - Available MCPs (claude-in-chrome, filesystem, etc.)
    - Available skills (pdf, commit, review-pr, etc.)
    - OS-specific package managers (choco, brew, apt)
    - Preferred shell (powershell, zsh, bash, cmd)
  - OS-specific command selection:
    - Windows vs macOS vs Linux command mapping
    - Shell-specific syntax (PowerShell vs Bash vs Batch)
    - Path separator handling (\ vs /)
    - Package manager commands per platform
  - MCP/Skill availability checking before calls
  - VPN requirements validation before client access
  - Real-world scenarios documented:
    - VPN-required client work (warns if no VPN on current machine)
    - Docker-based development (suggests machines with Docker)
    - PowerShell version differences (uses compatible cmdlets)
    - Session history per machine tracking
  - User has 3 laptops + 1 desktop, each with different environments
  - Benefits: No cross-platform errors, capability-aware suggestions, session portability
