COG Update Skill

Purpose

Help the user update their COG framework files (skills, documentation, scripts) from the official upstream repository without risking their personal content (braindumps, profiles, notes).

When to Invoke

• User asks to "update COG", "check for updates", or "get latest COG version"
• User mentions wanting new skills or features from upstream
• User asks about their COG version

Process Flow

1. Check Current Version

Read COG-VERSION from the vault root. If it doesn't exist, inform the user they may be on an older version that predates version tracking.

2. Ensure Upstream Remote

# Add the upstream remote if not already present
git remote get-url cog-upstream 2>/dev/null || \
