pm-upgrade

name	pm-upgrade
version	0.2.0
description	Upgrade nanopm to the latest version. Detects install type, runs the upgrade, shows what's new. Also handles inline upgrade prompts when UPGRADE_AVAILABLE appears in any skill preamble.
allowed-tools	Bash, Read, AskUserQuestion

Multi-host portability rules. When invoking AskUserQuestion:

1. The header field MUST be a short noun phrase (≤ 12 characters). Mistral Vibe rejects longer headers with string_too_long. Pick from: Start, Target, Scope, Audience, Methodology, Feature, Question.
2. The options list MUST have at least 2 items. Vibe rejects empty/single-option calls. For free-text input, always provide ≥ 2 framing options (e.g. Yes, here's the input / Skip) — never call ask_user_question with options: [].

Preamble (run first)

source ~/.nanopm/lib/nanopm.sh 2>/dev/null || \
  source .nanopm/lib/nanopm.sh 2>/dev/null || \
  { echo "ERROR: nanopm not installed. Run: curl -fsSL https://raw.githubusercontent.com/nmrtn/nanopm/main/setup | bash"; exit 1; }

Inline upgrade flow

This section is followed by all skill preambles when they detect UPGRADE_AVAILABLE {old} {new} in the preamble output.

Step 1: Ask or auto-upgrade

Check if auto-upgrade is configured:

source ~/.nanopm/lib/nanopm.sh 2>/dev/null || source .nanopm/lib/nanopm.sh 2>/dev/null || true
_AUTO=$(nanopm_config_get "auto_upgrade")
echo "AUTO_UPGRADE=${_AUTO:-false}"

If AUTO_UPGRADE=true: skip AskUserQuestion. Log "Auto-upgrading nanopm v{old} → v{new}..." and proceed to Step 2.

Otherwise, ask via AskUserQuestion:

• Question: "nanopm v{new} is available (you have v{old}). Upgrade now?"
• Options:
  • "Yes, upgrade now"
  • "Always keep me up to date (auto-upgrade)"
  • "Not now (remind me later)"
  • "Never ask again"

If "Yes, upgrade now": proceed to Step 2.

If "Always keep me up to date":

source ~/.nanopm/lib/nanopm.sh 2>/dev/null || source .nanopm/lib/nanopm.sh 2>/dev/null || true
nanopm_config_set "auto_upgrade" "true"

Tell user: "Auto-upgrade enabled — future updates will install automatically." Then proceed to Step 2.

If "Not now": write snooze state with escalating backoff. Then continue with the originally invoked skill without upgrading.

_SNOOZE="$HOME/.nanopm/update-snoozed"
_REMOTE_VER="{new}"
_CUR_LEVEL=0
if [ -f "$_SNOOZE" ]; then
  _SV=$(awk '{print $1}' "$_SNOOZE")
  if [ "$_SV" = "$_REMOTE_VER" ]; then
    _CUR_LEVEL=$(awk '{print $2}' "$_SNOOZE")
    case "$_CUR_LEVEL" in *[!0-9]*) _CUR_LEVEL=0 ;; esac
  fi
fi
_NEW_LEVEL=$(( _CUR_LEVEL + 1 ))
[ "$_NEW_LEVEL" -gt 3 ] && _NEW_LEVEL=3
echo "$_REMOTE_VER $_NEW_LEVEL $(date +%s)" > "$_SNOOZE"

Tell user the snooze duration: level 1 → "next reminder in 24h"; level 2 → "48h"; level 3 → "1 week".

If "Never ask again":

source ~/.nanopm/lib/nanopm.sh 2>/dev/null || source .nanopm/lib/nanopm.sh 2>/dev/null || true
nanopm_config_set "update_check_disabled" "1"
rm -f "$HOME/.nanopm/update-snoozed"

Tell user: "Update checks disabled. Re-enable with: nanopm_config_set update_check_disabled 0 in your shell."

Step 2: Detect install type

_LOCAL_REPO=""
# Check if we're inside the nanopm source repo
if [ -f "$(git rev-parse --show-toplevel 2>/dev/null)/pm-upgrade/SKILL.md" ] 2>/dev/null; then
  _LOCAL_REPO=$(git rev-parse --show-toplevel)
fi
# Check common clone locations
[ -z "$_LOCAL_REPO" ] && [ -f "$HOME/Code/nanopm/pm-upgrade/SKILL.md" ] && \
  _LOCAL_REPO="$HOME/Code/nanopm"
echo "LOCAL_REPO=${_LOCAL_REPO:-none}"

Step 3: Save current version

_OLD_VER=$(cat ~/.nanopm/VERSION 2>/dev/null || echo "unknown")
echo "OLD_VERSION=$_OLD_VER"

Step 4: Run upgrade

If LOCAL_REPO is set (git install):

cd "$_LOCAL_REPO"
git pull origin main
bash setup

If LOCAL_REPO is not set (curl / vendored install):

curl -fsSL https://raw.githubusercontent.com/nmrtn/nanopm/main/setup | bash

If the upgrade fails, tell the user: "Upgrade failed. Your current version (v{old}) is still active. Check your network connection or run the setup script manually."

Step 5: Clear update cache

rm -f ~/.nanopm/last-update-check
rm -f ~/.nanopm/update-snoozed

Step 6: Show what's new

Fetch the changelog from GitHub:

_CHANGELOG=$(curl -fsSL --max-time 5 \
  "https://raw.githubusercontent.com/nmrtn/nanopm/main/CHANGELOG.md" 2>/dev/null || echo "")
echo "$_CHANGELOG"

Find the section for the new version in the changelog. Summarize as 4-6 bullets grouped by theme (new skills, improvements, fixes). Don't list every line — focus on user-facing changes.

Format:

nanopm v{new} — upgraded from v{old}!

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

Step 7: Continue

After showing what's new, continue with the originally invoked skill (if this was an inline upgrade triggered by UPGRADE_AVAILABLE). If invoked standalone as /pm-upgrade, done.

---

Standalone usage

When invoked directly as /pm-upgrade:

1. Force a fresh update check:

source ~/.nanopm/lib/nanopm.sh
_CHECK=$(nanopm_update_check)
echo "CHECK: $_CHECK"

2. If UPGRADE_AVAILABLE {old} {new} in output: follow Steps 1-6 above.

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

STATUS: DONE
