What problem does it solve? When multiple AI tools (Claude, Codex, Hermes, Copilot, and others) contribute to a shared Obsidian wiki, their knowledge becomes siloed and it is hard to see which tool knows what. This Skill reads the vault's .manifest.json provenance metadata to let you browse, search, and compare knowledge by source tool, surfacing blind spots between tools. ## Core Features & Use Cases - Browse by Source Tool: List all wiki pages created or updated by a specific tool, grouped by category with tags and update dates. - Cross-Tool Diff: Compute pages unique to each tool, shared pages, and notable asymmetries to reveal knowledge gaps between AI assistants. - Origin Matrix Map: Render a page-by-tool matrix showing which tools contributed to each page, sorted by cross-tool richness. - Use Case: Run a diff between codex and claude to discover that codex has 12 pages on build tooling that claude has never touched, then decide which sessions to sync. ## Quick Start Ask the AI to run /memory-bridge diff to compare what each of your AI tools knows and surface the gaps between them.
