Instructions

When the user invokes /vault-search, follow these steps:

Step 0: Load Configuration

Read config.json from the engram project root to get the vault path:

{
  "vault_path": "~/Documents/Obsidian/WebCapture"
}

Use the vault_path value as {VAULT_PATH} in all paths below. Expand ~ to the user's home directory.

Step 1: Read the Index

Read {VAULT_PATH}/_system/index.json

This contains all notes with searchable metadata:

• id, path, title, type, topic
• url, source_domain, captured
• read, starred, tags, summary
• key_points, user_context

Step 2: Parse Query and Options

Extract:

• Free-text query (search in title, summary, tags, key_points, user_context)
• Filter options (topic, tags, type, unread, starred, since)

Step 3: Search and Filter

Apply filters in order:

1. Filter by --topic if specified
2. Filter by --tags if specified (match any)
3. Filter by --type if specified
4. Filter by --unread if specified (read === false)
5. Filter by --starred if specified
6. Filter by --since if specified
7. Search free-text query across text fields

For text search, check if query appears in (case-insensitive):

• title
• summary
• tags (any tag)
• key_points (any point)
• user_context

Step 4: Rank Results

Order by relevance:

1. Exact match in title (highest)
2. Match in user_context (user's intent)
3. Match in summary
4. Match in tags
5. Match in key_points
6. By capture date (recent first) for ties

Step 5: Format Results

For each result, show:

## [Title](path)
**Type:** article | **Topic:** ai-ml | **Captured:** 2026-02-05

> Summary text here

**Tags:** #tag1 #tag2 #tag3
**Why saved:** User context if available

Step 6: Offer Actions

After showing results, offer:

• "Want me to read any of these in full?"
• "Should I synthesize insights across these?"
• "Want to see related notes?"
• "Want to move any of these to a different topic?"

Step 7: Move Note (if --move)

If the user requests moving a note to a different topic, use obsidian-cli move which automatically updates all wiki-links across the vault:

obsidian-cli move "content/{old-topic}/{filename}" "content/{new-topic}/{filename}"

After moving:

1. Update index.json - change the note's topic and path fields
2. Update the old topic's _topic.md - remove the note entry
3. Update the new topic's _topic.md - add the note entry
4. Regenerate views (by-type, by-date, etc.)
5. Git sync vault

Synthesis Mode

If user asks to synthesize (e.g., "synthesize insights about X"):

1. Find all relevant notes using search
2. Read each note file in full
3. Extract key insights, patterns, themes
4. Create a synthesis that:
   • Identifies common threads
   • Notes contradictions or debates
   • Highlights actionable takeaways
   • Suggests connections the user might not have seen

Notes

• Vault: {VAULT_PATH}/
• Index: _system/index.json
• For quick lookups, use index only (no file reads)
• For deep dives, read actual note files or obsidian-cli print "{note-path}"
• obsidian-cli move handles wiki-link rewiring automatically when reorganizing notes
• obsidian-cli frontmatter "{note-path}" --print is a quick way to inspect a note's metadata
