NotFair Upgrade Tool

/notfair:upgrade

Upgrade the NotFair plugin to the latest version and show what's new.

Key paths

What	Path
Marketplace repo	~/.claude/plugins/marketplaces/nowork-studio/
Plugin cache	~/.claude/plugins/cache/nowork-studio/notfair/<version>/
Installed plugins	~/.claude/plugins/installed_plugins.json
Update state	~/.toprank/ (intentionally preserved — see CHANGELOG 0.24.0)

Inline upgrade flow

This section is used when a skill preamble outputs UPGRADE_AVAILABLE.

Step 1: Auto-upgrade

Log "Upgrading NotFair v{old} → v{new}..." and proceed to Step 2.

---

Step 2: Detect current install

First check for dev symlink (see "Dev symlink detection" section). If detected, stop — do not upgrade.

# Find the currently installed plugin path
INSTALLED_DIR=$(ls -d ~/.claude/plugins/cache/nowork-studio/notfair/*/ 2>/dev/null | grep -v '.bak' | head -1)
if [ -z "$INSTALLED_DIR" ]; then
  echo "ERROR: NotFair plugin not found in cache"; exit 1
fi
MARKETPLACE_DIR="$HOME/.claude/plugins/marketplaces/nowork-studio"
if [ ! -d "$MARKETPLACE_DIR/.git" ]; then
  echo "ERROR: marketplace repo not found at $MARKETPLACE_DIR"; exit 1
fi
echo "Current install: $INSTALLED_DIR"
echo "Marketplace repo: $MARKETPLACE_DIR"

Step 3: Save old version

OLD_VERSION=$(cat "$INSTALLED_DIR/VERSION" 2>/dev/null | tr -d '[:space:]' || echo "unknown")

Step 4: Update marketplace repo and install

cd "$MARKETPLACE_DIR"
git fetch origin
git reset --hard origin/main
NEW_VERSION=$(cat VERSION | tr -d '[:space:]')
GIT_SHA=$(git rev-parse HEAD)

# Create new versioned cache directory
NEW_CACHE_DIR="$HOME/.claude/plugins/cache/nowork-studio/notfair/$NEW_VERSION"
if [ -d "$NEW_CACHE_DIR" ]; then
  rm -rf "$NEW_CACHE_DIR"
fi
mkdir -p "$NEW_CACHE_DIR"

# Copy plugin files (exclude .git to save space)
rsync -a --exclude='.git' "$MARKETPLACE_DIR/" "$NEW_CACHE_DIR/"

If the copy fails, warn: "Upgrade failed — the old version is still active. Run /notfair:upgrade manually." and stop.

Step 5: Update installed_plugins.json

Read ~/.claude/plugins/installed_plugins.json, then update the notfair@nowork-studio entry:

python3 -c "
import json, os
from datetime import datetime, timezone

path = os.path.expanduser('~/.claude/plugins/installed_plugins.json')
with open(path) as f:
    data = json.load(f)

data['plugins']['notfair@nowork-studio'] = [{
    'scope': 'user',
    'installPath': os.path.expanduser('~/.claude/plugins/cache/nowork-studio/notfair/$NEW_VERSION'),
    'version': '$NEW_VERSION',
    'installedAt': data['plugins'].get('notfair@nowork-studio', [{}])[0].get('installedAt', datetime.now(timezone.utc).isoformat()),
    'lastUpdated': datetime.now(timezone.utc).isoformat(),
    'gitCommitSha': '$GIT_SHA'
}]

with open(path, 'w') as f:
    json.dump(data, f, indent=4)
print('Updated installed_plugins.json: notfair@nowork-studio -> v$NEW_VERSION')
"

Step 6: Clean up old cache versions

Remove old versioned cache directories (keep only the new one). Never remove a dev symlink:

for dir in ~/.claude/plugins/cache/nowork-studio/notfair/*/; do
  ver=$(basename "$dir")
  if [ "$ver" != "$NEW_VERSION" ] && [ "$ver" != "dev" ]; then
    rm -rf "$dir"
    echo "Removed old cache: $ver"
  fi
done

Step 7: Write marker + clear update state

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

Step 8: Show What's New

Read $NEW_CACHE_DIR/CHANGELOG.md. Find all version entries between the old version and the new version. Summarize as 3-7 bullets grouped by theme — focus on user-facing changes, skip internal refactors.

Format:

NotFair v{new} — upgraded from v{old}!

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

The new version will be fully active on your next Claude Code session.

Step 9: Continue

After showing What's New, continue with whatever skill the user originally invoked.

Dev symlink detection

Before upgrading, check if the installed cache directory is a symlink named dev:

CACHE_DIR=$(ls -d ~/.claude/plugins/cache/nowork-studio/notfair/*/ 2>/dev/null | head -1)
if [ -L "${CACHE_DIR%/}" ] && [ "$(basename "$CACHE_DIR")" = "dev" ]; then
  echo "DEV_SYMLINK"
fi

If DEV_SYMLINK: tell the user "NotFair is installed as a dev symlink — it always points to your local source (v$(cat "$CACHE_DIR/VERSION" 2>/dev/null | tr -d '[:space:]')). No upgrade needed." and stop. Do not proceed with Steps 2–8.

---

Standalone usage

When invoked directly as /notfair:upgrade:

1. Check for dev symlink (see "Dev symlink detection" above). If detected, stop.

2. Force a fresh update check (bypass cache and snooze):

_UPD_BIN=$(ls ~/.claude/plugins/cache/nowork-studio/notfair/*/bin/notfair-update-check 2>/dev/null | head -1)
[ -n "$_UPD_BIN" ] && _UPD=$("$_UPD_BIN" --force 2>/dev/null || true) || _UPD=""
echo "$_UPD"

3. If UPGRADE_AVAILABLE <old> <new>: follow Steps 2–8 above.

4. If no UPGRADE_AVAILABLE output: tell the user "You're already on the latest version (v{LOCAL})."
