Hex-Line Uninstaller

Type: L3 Worker Category: 0XX Shared

Removes all hex-line artifacts from the system. Standalone — no coordinator dependency.

What It Removes

| Artifact | Location | Action | |----------|----------|--------| | Hook script | ~/.claude/hex-line/hook.mjs | Delete file | | Hook entries | ~/.claude/settings.json → hooks | Remove entries matching "hex-line" signature | | Output style file | ~/.claude/output-styles/hex-line.md | Delete file | | Output style setting | ~/.claude/settings.json → outputStyle | Clear only if value is "hex-line" | | Hook directory | ~/.claude/hex-line/ | Delete if empty after hook removal |

Steps

1. Remove hook entries from settings.json

Read ~/.claude/settings.json
For each event in hooks (SessionStart, PreToolUse, PostToolUse):
  Find entry where hooks[].command contains "hex-line"
  Remove that entry
  If event array is empty, delete the key
If hooks object is empty, delete it
Write back

2. Clear output style

If settings.json.outputStyle === "hex-line":
  Delete the outputStyle key
  Write back

3. Delete installed files

rm -f ~/.claude/hex-line/hook.mjs
rmdir ~/.claude/hex-line 2>/dev/null   # only if empty
rm -f ~/.claude/output-styles/hex-line.md

4. Verify

# Confirm no hex-line references remain
grep -r "hex-line" ~/.claude/settings.json || echo "Clean"
test ! -f ~/.claude/hex-line/hook.mjs && echo "Hook removed"
test ! -f ~/.claude/output-styles/hex-line.md && echo "Style removed"

Notes

  • Does NOT remove the MCP server itself (npm uninstall -g @levnikolaevich/hex-line-mcp is separate)
  • Does NOT touch per-project .claude/settings.local.json (autoSync already cleans those)
  • Safe to run multiple times (idempotent)
  • After uninstall, restart Claude Code for changes to take effect

Definition of Done

  • [ ] No hex-line entries in ~/.claude/settings.json hooks
  • [ ] No outputStyle: "hex-line" in settings (unless user re-set it)
  • [ ] ~/.claude/hex-line/hook.mjs does not exist
  • [ ] ~/.claude/output-styles/hex-line.md does not exist
