| triggers | ["PreToolUse","PostToolUse"] |
Session memory. Checks past sessions before redundant research, planning, or debugging.
| Hook | When | Action |
|---|---|---|
| PreToolUse(WebSearch/WebFetch) | Before web research | Checks find_similar_queries() first |
| PreToolUse(EnterPlanMode) | Before planning | Searches search_plans() for past approaches |
| PreToolUse(Task) | Before agents | Checks find_tool_patterns() for workflows |
| PostToolUse(Bash) | After errors | Suggests get_error_solutions() |
| Command | Description |
|---|---|
/search-historian <query> | Search past sessions for solutions, decisions, context |

|---|---|---|
| Praetorian | Research will be compacted after | Praetorian prompts saving after web searches historian triggers |
| Oracle | Tools found for error patterns | Oracle searches for tools when historian finds recurring errors |
| Gladiator | Observations correlate with history | Past solutions enrich gladiator reflection |
| Vigil | Checkpoints complement history | File state preserved alongside session history |
| Tool | Purpose |
|---|---|
search_conversations | General history search |
find_similar_queries | Find related past questions |
get_error_solutions | Find how errors were fixed |
find_file_context | Track file changes |
find_tool_patterns | Discover successful workflows |
list_recent_sessions | Browse recent work |
search_plans | Find past implementation plans |

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 tool discovery across 17 sources — hooks search before planning and after errors, siblings avoid redundant searches
Context preservation with cross-session memory — hooks prompt compaction at high-impact moments, siblings enrich what gets saved
File checkpoint and recovery — auto-quicksaves before destructive commands, manual checkpoints for safe rollback
