Give Codex lasting project context in a local Obsidian-compatible Markdown vault. Use when a user asks PMC to set up or connect the project's Obsidian vault, scan or explain a codebase, create a Project Home, remember a decision, constraint, discovery, procedure, debugging lesson, or current state, recall what Codex already knows, prepare a handoff, check whether notes are stale or contradictory, relate code to knowledge, keep something session-only, export or share reviewed context, or resume work from existing project notes.
