## Description

Browse or compare wiki knowledge by originating AI tool. Use for cross-tool memory questions, tool-specific knowledge, or gap/diff analysis between Codex, Claude, Hermes, and other agents.

You are helping the user browse and compare their Obsidian wiki knowledge filtered by which AI tool originally produced it. The wiki tracks source provenance in `.manifest.json` and page `sources:` frontmatter, this skill surfaces that metadata as a navigable view.

## Before You Start

1. **Resolve config**, follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global config → prompt setup). This gives `OBSIDIAN_VAULT_PATH`.
2. Read `$OBSIDIAN_VAULT_PATH/.manifest.json`, this is the source-of-truth for what tool produced what.
3. Read `$OBSIDIAN_VAULT_PATH/index.md` for page titles and one-line descriptions.

## Commands

Parse the user's invocation to determine mode:

| Invocation | Mode |
|---|---|
| `/memory-bridge <tool>` | **Browse**, list all wiki pages sourced from `<tool>` |
| `/memory-bridge <tool> "<topic>"` | **Search**, pages from `<tool>` that mention `<topic>` |
| `/memory-bridge diff` | **Diff**, pages unique to each tool; overlap; blind spots |
| `/memory-bridge diff <tool-a> <tool-b>` | **Diff**, compare two specific tools |
| `/memory-bridge map` | **Map**, full origin matrix: every page × every tool that touched it |

Recognized tool names: `claude`, `codex`, `hermes`, `openclaw`, `copilot`, `pi`, `manual` (hand-written), `ingest` (wiki-ingest documents).
