Fundraising Upgrade

Step 3: Detect Install Type

Check where the skill is installed:

# Global git clone
if [ -d "$HOME/.claude/skills/fundraising/.git" ]; then
    INSTALL_TYPE="global-git"
    INSTALL_DIR="$HOME/.claude/skills/fundraising"

# Project-level git clone
elif [ -d ".claude/skills/fundraising/.git" ]; then
    INSTALL_TYPE="local-git"
    INSTALL_DIR=".claude/skills/fundraising"

# Global vendored (no .git)
elif [ -d "$HOME/.claude/skills/fundraising" ]; then
    INSTALL_TYPE="vendored-global"
    INSTALL_DIR="$HOME/.claude/skills"

# Project-level vendored
elif [ -d ".claude/skills/fundraising" ]; then
    INSTALL_TYPE="vendored-local"
    INSTALL_DIR=".claude/skills"
fi

Step 4: Save Old Version

OLD_VERSION=$(cat "$INSTALL_DIR/fundraising/VERSION" 2>/dev/null || cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")

Step 5: Upgrade

For git installs:

# Find the repo root (parent of the skill directories)
cd "$REPO_ROOT"
git fetch origin
git pull --ff-only origin main

For vendored installs (installed via install.sh or manual copy):

# Re-run the install script
curl -sL https://raw.githubusercontent.com/lowesyang/fundraising-skill/main/install.sh | bash -s -- --global

Or if project-level:

curl -sL https://raw.githubusercontent.com/lowesyang/fundraising-skill/main/install.sh | bash

Step 6: Write Upgrade Markers

mkdir -p ~/.fundraising-skill
echo "$OLD_VERSION" > ~/.fundraising-skill/just-upgraded-from
rm -f ~/.fundraising-skill/last-update-check

Step 7: Show What's New

Read CHANGELOG.md from the installed skill directory. Extract entries between the old version and the new version. Summarize as 5-7 user-facing bullets:

fundraising-skill v{new} — upgraded from v{old}!

What's new:
- [bullet 1]
- [bullet 2]
- ...

If CHANGELOG.md is not available, just show the version change.

Version Check in Other Skills

Each fundraising skill can optionally check for updates on load by reading the update-check script output. This is lightweight (cached for 60 minutes, fails silently on network error).

To add version checking to a skill's preamble, include this note in the SKILL.md:

Before starting, check for updates:
Run `~/.claude/skills/fundraising/bin/fundraising-update-check` silently.
If output contains UPGRADE_AVAILABLE, mention: "A new version of fundraising-skill
is available. Run /fundraising-upgrade to update."

This is optional and non-blocking. The skill should continue normally regardless of the update check result.
