// Context preservation with cross-session memory — hooks prompt compaction at high-impact moments, siblings enrich what gets saved
Prompt rhetoric coach — deterministic scoring and restructuring using Anthropic best practices
Continuous learning — hooks observe failures and prompt reflection, sibling synergy deepens analysis with history and tool discovery
Automatic history search — checks past sessions before web research, planning, and debugging, siblings deepen coverage
Automatic tool discovery across 17 sources — hooks search before planning and after errors, siblings avoid redundant searches
File checkpoint and recovery — auto-quicksaves before destructive commands, manual checkpoints for safe rollback

Context guard. Saves and restores valuable context at the right moments — before planning, after research, when subagents complete.
| Hook | When | Action |
|---|---|---|
| PreToolUse(EnterPlanMode) | Before planning | Lists prior compactions, suggests restoring |
| PreCompact | Before context resets | Prompts to save decisions/insights/findings |
| PostToolUse(WebFetch/WebSearch) | After web research | Prompts to compact as web_research |
| SubagentStop | After subagent completes | Prompts to compact as task_result |
| Command | Description |
|---|---|
/compact-praetorian [type] [title] | Save current context |
/restore-praetorian [query] | Load previous context |
