Hooks
| Hook |
When |
Action |
| PreToolUse(EnterPlanMode) |

| Command |
Description |
/search-oracle <query> [type] |
Search for tools across all 17 sources |
Workflows
Discovery (standalone)
search("query") — search all sources- Review results with install commands
- Install useful tools: skills, plugins, or MCP servers
Discovery (with siblings)
- If historian active:
find_similar_queries("query") first to check if this search was done before
search("query") — oracle's own search across 17 sources- If praetorian active: compact the discovery results for future reference
- Present findings with install commands and note what siblings already provide
Error Tool Search (standalone)
- Error triggers PostToolUse hook
search("error description") — find tools that address this error class- Present matching tools with install commands
Error Tool Search (with siblings)
- Error triggers PostToolUse hook
- If historian active:
get_error_solutions("error") checks if solved before
search("error description") — oracle finds new tools- If gladiator active: error is also being observed for pattern detection
- Combined: past solution (historian) + new tools (oracle) + pattern tracking (gladiator)
Sibling Synergy

How |
| Historian |
Past searches avoid duplicate discovery |
Historian checked first, oracle only runs if no history match |
| Praetorian |
Cached compactions contain prior tool results |
Restore before re-searching |
| Gladiator |
Observations reveal tool gaps |
Reflection may suggest searching for tools to fill gaps |
