description	Check for and install hindsight-skills updates. Detects new versions, offers upgrade options, and shows what changed.

Hindsight Skills Upgrade

You manage upgrades for hindsight-skills. This skill is invoked in two ways:

1. Automatically by the preamble when UPGRADE_AVAILABLE or JUST_UPGRADED is detected
2. Directly by the user via /hindsight-upgrade

---

Inline Upgrade Flow (called by preamble)

When the preamble detects UPGRADE_AVAILABLE <old> <new>, follow these steps:

Step 1: Check auto_upgrade preference

# Check if auto-upgrade is enabled
_HS_BIN_DIR=""
for _d in ~/.claude/skills ~/.codex/skills ~/.kiro/skills ~/.factory/skills; do
  [ -x "$_d/hindsight-upgrade/bin/hindsight-config" ] && _HS_BIN_DIR="$_d/hindsight-upgrade/bin" && break
done
[ -n "$_HS_BIN_DIR" ] && _AUTO_UPGRADE=$("$_HS_BIN_DIR/hindsight-config" get auto_upgrade 2>/dev/null || echo "false")
echo "AUTO_UPGRADE: ${_AUTO_UPGRADE:-false}"

If AUTO_UPGRADE is true, skip to Step 2 and proceed with the upgrade silently.

If AUTO_UPGRADE is false, use AskUserQuestion to ask:

hindsight-skills {new} is available (you have {old}). How would you like to proceed?

Options:

• Upgrade now — Install the update and continue
• Always auto-upgrade — Install now and auto-upgrade in the future
• Snooze 24h — Remind me tomorrow
• Never ask — Disable update checks permanently

Handle each response:

• Upgrade now: proceed to Step 2
• Always auto-upgrade: run hindsight-config set auto_upgrade true, then proceed to Step 2
• Snooze 24h: write snooze file and stop

# Snooze for 24 hours
_HS_STATE_DIR="${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}"
echo "{new_version} $(date +%s)" > "$_HS_STATE_DIR/update-snoozed"

• Never ask: run hindsight-config set update_check false and stop

Step 2: Detect install type

# Read the install source breadcrumb
_HS_STATE_DIR="${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}"
_INSTALL_SOURCE=""
[ -f "$_HS_STATE_DIR/install-source" ] && _INSTALL_SOURCE=$(cat "$_HS_STATE_DIR/install-source")
echo "INSTALL_SOURCE: ${_INSTALL_SOURCE:-not found}"

If INSTALL_SOURCE is empty or the path doesn't exist, tell the user:

I can't find the hindsight-skills installation. Please re-run setup from your clone:

cd /path/to/hindsight-skills && ./setup

And stop.

Step 3: Save old version

_HS_STATE_DIR="${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}"
_INSTALL_SOURCE=$(cat "$_HS_STATE_DIR/install-source")
_OLD_VERSION=$(cat "$_INSTALL_SOURCE/VERSION" 2>/dev/null | tr -d '[:space:]')
echo "OLD_VERSION: $_OLD_VERSION"

Step 4: Upgrade

Check if the install source is a git repo:

_INSTALL_SOURCE=$(cat "${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}/install-source")
cd "$_INSTALL_SOURCE"
if [ -d .git ]; then
  echo "INSTALL_TYPE: git"
else
  echo "INSTALL_TYPE: vendored"
fi

Git install:

_INSTALL_SOURCE=$(cat "${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}/install-source")
cd "$_INSTALL_SOURCE" && git pull origin main && ./setup

Vendored install (no .git directory — downloaded/copied, not cloned):

_INSTALL_SOURCE=$(cat "${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}/install-source")
_PARENT=$(dirname "$_INSTALL_SOURCE")
_NAME=$(basename "$_INSTALL_SOURCE")
cd "$_PARENT"
# Clone fresh, run setup, move into place
git clone https://github.com/vectorize-io/hindsight-skills.git "${_NAME}-upgrade-tmp"
cd "${_NAME}-upgrade-tmp" && ./setup
cd "$_PARENT"
rm -rf "$_NAME"
mv "${_NAME}-upgrade-tmp" "$_NAME"

Step 5: Write marker and clear state

_HS_STATE_DIR="${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}"
echo "$_OLD_VERSION" > "$_HS_STATE_DIR/just-upgraded-from"
rm -f "$_HS_STATE_DIR/last-update-check"
rm -f "$_HS_STATE_DIR/update-snoozed"

Step 6: Show What's New

Read the CHANGELOG.md from the installed skill and show the user what changed between their old version and the new version:

# Find the changelog
for _d in ~/.claude/skills ~/.codex/skills ~/.kiro/skills ~/.factory/skills; do
  [ -f "$_d/hindsight-upgrade/CHANGELOG.md" ] && cat "$_d/hindsight-upgrade/CHANGELOG.md" && break
done

Parse the changelog and display only the sections between the old and new versions. Format as:

hindsight-skills upgraded: {old} → {new}

{relevant changelog entries}

Then continue with the user's original task.

---

Handling JUST_UPGRADED

When the preamble detects JUST_UPGRADED <old> <new>, the upgrade already happened in a previous session. Show What's New (Step 6 above) and continue.

---

Standalone Usage

When invoked directly as /hindsight-upgrade:

Force check (bypass cache)

# Clear cache and run check
_HS_STATE_DIR="${HINDSIGHT_SKILLS_STATE_DIR:-$HOME/.hindsight-skills}"
rm -f "$_HS_STATE_DIR/last-update-check"
rm -f "$_HS_STATE_DIR/update-snoozed"

# Find and run the update check
for _d in ~/.claude/skills ~/.codex/skills ~/.kiro/skills ~/.factory/skills; do
  [ -x "$_d/hindsight-upgrade/bin/hindsight-update-check" ] && "$_d/hindsight-upgrade/bin/hindsight-update-check" && break
done

If the output is UPGRADE_AVAILABLE, follow the Inline Upgrade Flow from Step 1.

If the output is empty, tell the user: "hindsight-skills is up to date (version {version})."

If the output is JUST_UPGRADED, show What's New.

Config management

Users can also use /hindsight-upgrade to manage settings:

• "enable auto-upgrade" → hindsight-config set auto_upgrade true
• "disable update checks" → hindsight-config set update_check false
• "re-enable update checks" → hindsight-config set update_check true
• "show config" → hindsight-config list
