# gstack-uninstall — remove gstack skills, state, and browse daemons

#

# Usage:

# gstack-uninstall — interactive uninstall (prompts before removing)

# gstack-uninstall --force — remove everything without prompting

# gstack-uninstall --keep-state — remove skills but keep ~/.gstack/ data

#

# What gets REMOVED:

# ~/.claude/skills/gstack — global Claude skill install (git clone or vendored)

# ~/.claude/skills/{skill} — per-skill symlinks created by setup

# ~/.codex/skills/gstack* — Codex skill install + per-skill symlinks

# ~/.kiro/skills/gstack* — Kiro skill install + per-skill symlinks

# ~/.gstack/ — global state (config, analytics, sessions, projects,

# repos, installation-id, browse error logs)

# .claude/skills/gstack* — project-local skill install (--local installs)

# .gstack/ — per-project browse state (in current git repo)

# .gstack-worktrees/ — per-project test worktrees (in current git repo)

# .agents/skills/gstack* — Codex/Gemini/Cursor sidecar (in current git repo)

# Running browse daemons — stopped via SIGTERM before cleanup

#

# What is NOT REMOVED:

# ~/Library/Caches/ms-playwright/ — Playwright Chromium (shared, may be used by other tools)

# ~/.gstack-dev/ — developer eval artifacts (only present in gstack contributors)

#

# Env overrides (for testing):

# GSTACK_DIR — override auto-detected gstack root

# GSTACK_STATE_DIR — override ~/.gstack state directory

#

# NOTE: Uses set -uo pipefail (no -e) — uninstall must never abort partway.
