Dicklesworthstone/post_compact_reminder

Integrates with Claude Code's SessionStart hook system using a `compact` matcher to detect context compaction events and inject reminders directly into the conversation context. Provides four built-in message templates (minimal, detailed, checklist, default) plus custom message support, with atomic file operations and automatic backups to ensure `settings.json` integrity. Installs globally via a single self-updating bash script that handles dependency detection, validation, and diagnostics without requiring frameworks or build steps.
