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 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 . Read $OBSIDIAN_VAULT_PATH/.manifest.json — this is the source-of-truth for what tool produced what. 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 Browse — list all wiki pages sourced from /memory-bridge "" Search — pages from that mention /memory-bridge diff Diff — pages unique to each tool; overlap; blind spots /memory-bridge diff 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 , 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 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[] and present as a grouped list:

Knowledge from ( 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 ""
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 — vs
### Only in ( pages)
These concepts exist in your wiki from sessions but has never touched them.

### Only in ( pages)

### Shared ( pages)
Both tools have contributed to these pages.

### Notable gaps

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

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= 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.
