Codex Skill: Search

How to find specific information in the codex — for humans and AI agents.

Search Hierarchy

Work from fastest to most thorough:

Level 1 — Direct navigation

If you know where it lives:

_codex/INTERFACE.md → domain README → specific file

Level 2 — Tag search

Use Obsidian’s tag panel or grep:

#type/decision       → all decision records
#type/sop            → all SOPs
#domain/ui           → everything in UI quadrant
#status/active       → only active items
#cadence/weekly      → weekly review notes

Level 3 — Full text search

In Obsidian: Cmd+Shift+F → search any term For agents: use memory_search with semantic query

Level 4 — AI semantic search

Ask your AI: “find everything about X in my codex” The agent will use semantic search across ai_summary fields and content.

Agent Search Protocol

When an agent needs to find information:

1. Check _codex/system/ first (always-loaded context)
2. Check the relevant domain README for navigation
3. Use semantic search on ai_summary fields (fast, low token cost)
4. Open specific files only when the summary isn’t sufficient

Never open every file looking for something — read summaries first.
