Update

First, derive PREFERRED_CONFIG_DIR and PREFERRED_RUNTIME from the invoking prompt's execution_context path:

• If the path contains /get-shit-done/workflows/update.md, strip that suffix and store the remainder as PREFERRED_CONFIG_DIR
• Path contains /.codex/ -> codex
• Path contains /.gemini/ -> gemini
• Path contains /.config/kilo/ or /.kilo/, or PREFERRED_CONFIG_DIR contains kilo.json / kilo.jsonc -> kilo
• Path contains /.config/opencode/ or /.opencode/, or PREFERRED_CONFIG_DIR contains opencode.json / opencode.jsonc -> opencode
• Otherwise -> claude

Use PREFERRED_CONFIG_DIR when available so custom --config-dir installs are checked before default locations. Use PREFERRED_RUNTIME as the first runtime checked so /gsd-update targets the runtime that invoked it.

Kilo config precedence must match the installer: KILO_CONFIG_DIR -> dirname(KILO_CONFIG) -> XDG_CONFIG_HOME/kilo -> ~/.config/kilo.

Parse output:

• Line 1 = installed version (0.0.0 means unknown version)
• Line 2 = install scope (LOCAL, GLOBAL, or UNKNOWN)
• Line 3 = target runtime (claude, opencode, gemini, kilo, or codex)
• If scope is UNKNOWN, proceed to install step using --claude --global fallback.

If multiple runtime installs are detected and the invoking runtime cannot be determined from execution_context, ask the user which runtime to update before running install.

If VERSION file missing:

## GSD Update

**Installed version:** Unknown

Your installation doesn't include version tracking.

Running fresh install...

Proceed to install step (treat as version 0.0.0 for comparison).

npm view get-shit-done-cc version 2>/dev/null

If npm check fails:

Couldn't check for updates (offline or npm unavailable).

To update manually: `npx get-shit-done-cc --global`

Exit.

If installed == latest:

## GSD Update

**Installed:** X.Y.Z
**Latest:** X.Y.Z

You're already on the latest version.

Exit.

If installed > latest:

## GSD Update

**Installed:** X.Y.Z
**Latest:** A.B.C

You're ahead of the latest release — this looks like a dev install.

If you see a "⚠ dev install — re-run installer to sync hooks" warning in
your statusline, your hook files are older than your VERSION file. Fix it
by re-running the local installer from your dev branch:

    node bin/install.js --global --claude

Running /gsd-update would install the npm release (A.B.C) and downgrade
your dev version — do NOT use it to resolve this warning.

Exit.

## GSD Update Available

**Installed:** 1.5.10
**Latest:** 1.5.15

### What's New
────────────────────────────────────────────────────────────

## [1.5.15] - 2026-01-20

### Added
- Feature X

## [1.5.14] - 2026-01-18

### Fixed
- Bug fix Y

────────────────────────────────────────────────────────────

⚠️  **Note:** The installer performs a clean install of GSD folders:
- `commands/gsd/` will be wiped and replaced
- `get-shit-done/` will be wiped and replaced
- `agents/gsd-*` files will be replaced

(Paths are relative to detected runtime install location:
global: `~/.claude/`, `~/.config/opencode/`, `~/.opencode/`, `~/.gemini/`, `~/.config/kilo/`, or `~/.codex/`
local: `./.claude/`, `./.config/opencode/`, `./.opencode/`, `./.gemini/`, `./.kilo/`, or `./.codex/`)

Your custom files in other locations are preserved:
- Custom commands not in `commands/gsd/` ✓
- Custom agents not prefixed with `gsd-` ✓
- Custom hooks ✓
- Your CLAUDE.md files ✓

If you've modified any GSD files directly, they'll be automatically backed up to `gsd-local-patches/` and can be reapplied with `/gsd-reapply-patches` after the update.

Text mode (workflow.text_mode: true in config or --text flag): Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where AskUserQuestion is not available. Use AskUserQuestion:

• Question: "Proceed with update?"
• Options:
  • "Yes, update now"
  • "No, cancel"

If user cancels: Exit.

Do not use bash path-stripping (${filepath#$RUNTIME_DIR/}) or node -e require() inline — those patterns fail when $RUNTIME_DIR is unset and the stripped relative path may not match manifest key format, which causes CUSTOM_COUNT=0 even when custom files exist (bug #1997). Use gsd-sdk query detect-custom-files when gsd-sdk is on PATH, or the bundled gsd-tools.cjs detect-custom-files otherwise — both resolve paths reliably with Node.js path.relative().

First, resolve the config directory (RUNTIME_DIR) from the install scope detected in get_installed_version:

# RUNTIME_DIR is the resolved config directory (e.g. ~/.config/opencode, ~/.gemini)
# It should already be set from get_installed_version as GLOBAL_DIR or LOCAL_DIR.
# Use the appropriate variable based on INSTALL_SCOPE.
if [ "$INSTALL_SCOPE" = "LOCAL" ]; then
  RUNTIME_DIR="$LOCAL_DIR"
elif [ "$INSTALL_SCOPE" = "GLOBAL" ]; then
  RUNTIME_DIR="$GLOBAL_DIR"
else
  RUNTIME_DIR=""
fi

If RUNTIME_DIR is empty or does not exist, skip this step (no config dir to inspect).

Otherwise run detect-custom-files (prefer SDK when available):

GSD_TOOLS="$RUNTIME_DIR/get-shit-done/bin/gsd-tools.cjs"
CUSTOM_JSON=''
if [ -n "$RUNTIME_DIR" ] && command -v gsd-sdk >/dev/null 2>&1; then
  CUSTOM_JSON=$(gsd-sdk query detect-custom-files --config-dir "$RUNTIME_DIR" 2>/dev/null)
elif [ -f "$GSD_TOOLS" ] && [ -n "$RUNTIME_DIR" ]; then
  CUSTOM_JSON=$(node "$GSD_TOOLS" detect-custom-files --config-dir "$RUNTIME_DIR" 2>/dev/null)
fi
if [ -z "$CUSTOM_JSON" ]; then
  CUSTOM_JSON='{"custom_files":[],"custom_count":0}'
fi
CUSTOM_COUNT=$(echo "$CUSTOM_JSON" | node -e "process.stdin.resume();let d='';process.stdin.on('data',c=>d+=c);process.stdin.on('end',()=>{try{console.log(JSON.parse(d).custom_count);}catch{console.log(0);}})" 2>/dev/null || echo "0")

If CUSTOM_COUNT > 0:

Back up each custom file to $RUNTIME_DIR/gsd-user-files-backup/ before the installer wipes the directories:

BACKUP_DIR="$RUNTIME_DIR/gsd-user-files-backup"
mkdir -p "$BACKUP_DIR"

# Parse custom_files array from CUSTOM_JSON and copy each file
node - "$RUNTIME_DIR" "$BACKUP_DIR" "$CUSTOM_JSON" <<'JSEOF'
const [,, runtimeDir, backupDir, customJson] = process.argv;
const { custom_files } = JSON.parse(customJson);
const fs = require('fs');
const path = require('path');
for (const relPath of custom_files) {
  const src = path.join(runtimeDir, relPath);
  const dst = path.join(backupDir, relPath);
  if (fs.existsSync(src)) {
    fs.mkdirSync(path.dirname(dst), { recursive: true });
    fs.copyFileSync(src, dst);
    console.log('  Backed up: ' + relPath);
  }
}
JSEOF

Then inform the user:

⚠️  Found N custom file(s) inside GSD-managed directories.
    These have been backed up to gsd-user-files-backup/ before the update.
    Restore them after the update if needed.

If CUSTOM_COUNT == 0: No user-added files detected. Continue to install.

Build runtime flag from step 1:

RUNTIME_FLAG="--$TARGET_RUNTIME"

If LOCAL install:

npx -y get-shit-done-cc@latest "$RUNTIME_FLAG" --local

If GLOBAL install:

npx -y get-shit-done-cc@latest "$RUNTIME_FLAG" --global

If UNKNOWN install:

npx -y get-shit-done-cc@latest --claude --global

Capture output. If install fails, show error and exit.

Clear the update cache so statusline indicator disappears:

expand_home() {
  case "$1" in
    "~/"*) printf '%s/%s\n' "$HOME" "${1#~/}" ;;
    *) printf '%s\n' "$1" ;;
  esac
}

fi
if [ -n "$OPENCODE_CONFIG_DIR" ]; then
  CACHE_DIRS+=( "$(expand_home "$OPENCODE_CONFIG_DIR")" )
elif [ -n "$OPENCODE_CONFIG" ]; then
  CACHE_DIRS+=( "$(dirname "$(expand_home "$OPENCODE_CONFIG")")" )
elif [ -n "$XDG_CONFIG_HOME" ]; then
  CACHE_DIRS+=( "$(expand_home "$XDG_CONFIG_HOME")/opencode" )
fi
if [ -n "$CODEX_HOME" ]; then
  CACHE_DIRS+=( "$(expand_home "$CODEX_HOME")" )
fi

for dir in "${CACHE_DIRS[@]}"; do
  if [ -n "$dir" ]; then
    rm -f "$dir/cache/gsd-update-check.json"
  fi
done

for dir in .claude .config/opencode .opencode .gemini .config/kilo .kilo .codex; do
  rm -f "./$dir/cache/gsd-update-check.json"
  rm -f "$HOME/$dir/cache/gsd-update-check.json"
done

The SessionStart hook (gsd-check-update.js) writes to the detected runtime's cache directory, so preferred/env-derived paths and default paths must all be cleared to prevent stale update indicators.
