Browse and compare wiki knowledge by which AI tool originally produced it. Use this skill when the user
|
||
says "/memory-bridge", "browse codex memory", "what did codex know about X", "show me claude knowledge",
|
||
"cross-tool memory", "what does hermes know that claude doesn't", "show me knowledge from <tool>",
|
||
"compare my AI tool memories", or wants to explore knowledge gaps between tools. Works from any project.
|
||
Diff mode ("what's different", "unique to codex", "gaps between tools") is the killer feature — it surfaces
|
||
blind spots between tools that the user may not know exist.

# Memory Bridge — Cross-Tool Knowledge Browser
|
||
|
||
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` (walk up CWD for `.env` → `~/.obsidian-wiki/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).
|
||
|
||
## Step 1: Build the Source Map
|
||
|
||
Read `.manifest.json`. For each source entry, extract:
|
||
- `source_type` — maps to tool name:
|
||
- `claude_conversation`, `claude_memory`, `claude_audit_log`, `claude_desktop_session` → `claude`
|
||
- `codex_rollout`, `codex_index`, `codex_history` → `codex`
|
||
- `hermes_memory`, `hermes_session` → `hermes`
|
||
- `openclaw_memory`, `openclaw_daily_note`, `openclaw_session`, `openclaw_dreams` → `openclaw`
|
||
- `copilot_session`, `copilot_checkpoint`, `copilot_transcript`, `copilot_memory_artifact` → `copilot`
|
||
- `pi_session` → `pi`
|
||
- `document` → `ingest`
|
||
- anything else → `manual`
|
||
- `pages_created` and `pages_updated` — the wiki pages that came out of this source
|
||
|
||
Build a map:
|
||
|
||
```
|
||
tool_pages = {
|
||
"claude": set(pages created/updated by claude sources),
|
||
"codex": set(pages created/updated by codex sources),
|
||
...
|
||
}
|
||
```
|
||
|
||
A page can appear in multiple tools' sets if multiple tools contributed to it.
|
||
|
||
## Step 2: Execute the Mode
|
||
|
||
### Browse Mode
|
||
|
||
Filter `tool_pages[<tool>]` and present as a grouped list:
|
||
|
||
```
|
||
## Knowledge from <tool> (<N> pages)
|
||
|
||
### By category
|
||
- concepts/ — N pages
|
||
- entities/ — N pages
|
||
- skills/ — N pages
|
||
...
|
||
|
||
### Pages
|
||
| Page | Category | Tags | Last updated |
|
||
|------|----------|------|--------------|
|
||
| [[page-name]] | concept | tag1, tag2 | 2026-04-10 |
|
||
...
|
||
```
|
||
|
||
Read frontmatter for the listed pages (grep for `^(title|category|tags|updated):`) — do not read full page bodies unless the user asks.
|
||
|
||
### Search Mode
|
||
|
||
Within the filtered page set, run:
|
||
```
|
||
grep -l "<topic>" <pages in tool set>
|
||
```
|
||
Then grep section headers (`^##`) around matches to give context without full reads. Present results as a ranked list with the matching excerpt.
|
||
|
||
### Diff Mode
|
||
|
||
Compute:
|
||
- `only_in_a` = `tool_pages[a]` − `tool_pages[b]`
|
||
- `only_in_b` = `tool_pages[b]` − `tool_pages[a]`
|
||
- `shared` = `tool_pages[a]` ∩ `tool_pages[b]`
|
||
|
||
If no specific tools are given, compare all tools pairwise (limit to pairs with >0 overlap or unique pages to keep output concise).
|
||
|
||
Present:
|
||
|
||
```
|
||
## Memory Bridge Diff — <tool-a> vs <tool-b>
|
||
|
||
### Only in <tool-a> (<N> pages)
|
||
These concepts exist in your wiki from <tool-a> sessions but <tool-b> has never touched them.
|
||
<list with one-line descriptions from index.md>
|
||
|
||
### Only in <tool-b> (<N> pages)
|
||
<list>
|
||
|
||
### Shared (<N> pages)
|
||
Both tools have contributed to these pages.
|
||
<list — only show if ≤15; otherwise just the count>
|
||
|
||
### Notable gaps
|
||
<highlight the most interesting asymmetries — e.g. "codex has 12 pages on build tooling that claude has never seen">
|
||
```
|
||
|
||
### Map Mode
|
||
|
||
Build a matrix showing every page and which tools have touched it. Cap at 50 rows; sort by number of contributing tools descending (most cross-tool pages first — these are the richest nodes).
|
||
|
||
```
|
||
| Page | claude | codex | hermes | copilot | pi |
|
||
|------|--------|-------|--------|---------|----|
|
||
| [[react-patterns]] | ✓ | ✓ | — | ✓ | — |
|
||
| [[rust-ownership]] | — | ✓ | — | — | ✓ |
|
||
```
|
||
|
||
## Step 3: Spawn impl-validator (if available)
|
||
|
||
After generating output, if the `impl-validator` skill is available in the current environment, spawn it as a subagent:
|
||
|
||
```
|
||
impl-validator check:
|
||
goal: "Browse/diff wiki knowledge by source tool and surface cross-tool blind spots"
|
||
artifacts: [the output you just generated]
|
||
checks:
|
||
- Did you correctly parse source_type from .manifest.json?
|
||
- Are page counts plausible (not 0 unless vault is empty)?
|
||
- Is the diff symmetric (a−b and b−a are disjoint)?
|
||
- Did you avoid reading full page bodies when not needed?
|
||
```
|
||
|
||
Apply any issues it surfaces before presenting output to the user.
|
||
|
||
## Step 4: Log
|
||
|
||
Append to `$OBSIDIAN_VAULT_PATH/log.md`:
|
||
```
|
||
- [TIMESTAMP] MEMORY-BRIDGE mode=<browse|search|diff|map> tool=<tool> pages_shown=N
|
||
```
|
||
|
||
## Output Conventions
|
||
|
||
- Always show page counts so the user can calibrate how much knowledge is in each tool's silo.
|
||
- Use `[[wikilinks]]` for page references (or standard Markdown links if `OBSIDIAN_LINK_FORMAT=markdown` is set).
|
||
- In diff mode, call out the most *surprising* asymmetry explicitly — that's the insight the user came for.
|
||
- If `.manifest.json` is empty or missing, say so clearly and suggest running `/wiki-history-ingest` first.
