Knowledge Base

Knowledge Base

A local SQLite database for indexing and querying personal data with full-text search.

What It Indexes

Quick Start

# Initialize database (first time)
python3 skills/knowledge-base/scripts/init_db.py

# Query
python3 skills/knowledge-base/scripts/query.py search "term"
python3 skills/knowledge-base/scripts/query.py contact "+34659..."
python3 skills/knowledge-base/scripts/query.py stats

Commands

Data Sources

WhatsApp Contacts

Export via the WhatsApp skill's contact extraction (produces bank/whatsapp-contacts-full.json).

ChatGPT Export

Use the chatgpt-exporter skill or manual export. Place JSON in chatgpt-export/ directory.

Supported formats:

• { "conversations": [...] } — custom format with id, title, created, messages
• Native ChatGPT export format with mapping structure

VCF Contacts

Export from phone (Android: Contacts → Settings → Export). Run:

python3 skills/knowledge-base/scripts/import_vcf.py path/to/contacts.vcf

Documents

Automatically indexes all *.md files in memory/ directory.

Database Location

db/jarvis.db in workspace root.

Re-indexing

To refresh the database with new data:

rm db/jarvis.db
python3 skills/knowledge-base/scripts/init_db.py

Or for incremental updates:

python3 skills/knowledge-base/scripts/sync.py  # (if available)

Schema

See references/schema.md for full table definitions.

Key tables:

• contacts — phone, name, source
• wa_groups — WhatsApp group metadata
• wa_memberships — who is in which group
• documents — markdown files with FTS
• chatgpt_conversations — conversation metadata
• chatgpt_messages — individual messages with FTS

Example Queries

-- Find all groups someone is in
SELECT g.name FROM wa_groups g
JOIN wa_memberships m ON m.group_jid = g.jid
WHERE m.phone = '+34659418105';

-- Search ChatGPT for a topic
SELECT c.title, m.content FROM chatgpt_fts f
JOIN chatgpt_messages m ON m.conversation_id = f.conv_id
JOIN chatgpt_conversations c ON c.id = m.conversation_id
WHERE chatgpt_fts MATCH 'spirituality';

-- Find contacts in a specific group
SELECT c.phone, c.name FROM contacts c
JOIN wa_memberships m ON m.phone = c.phone
JOIN wa_groups g ON g.jid = m.group_jid
WHERE g.name LIKE '%Family%';

WhatsApp Group Allowlist Management

The database enables easy management of WhatsApp group allowlists for security.

Find a group's JID

python3 skills/knowledge-base/scripts/query.py sql \
  "SELECT jid, name, participant_count FROM wa_groups WHERE name LIKE '%Family%'"

List all allowed groups (cross-reference with config)

python3 skills/knowledge-base/scripts/query.py sql \
  "SELECT name, participant_count FROM wa_groups WHERE jid IN (
    '34609572036-1370260813@g.us',
    '34659418105-1561917865@g.us'
    -- add your allowlist JIDs here
  )"

Add a group to allowlist

1. Find the JID: query.py sql "SELECT jid, name FROM wa_groups WHERE name LIKE '%GroupName%'"
2. Add to config: channels.whatsapp.groupAllowFrom
3. Restart gateway

Security rationale

• groupPolicy: "open" = any group can trigger the bot (risky with large public groups)
• groupPolicy: "allowlist" = only specified groups can interact (recommended)
• Reduces prompt injection attack surface by ~95%

Tips

1. No contact names? WhatsApp only provides phone numbers. Import your phone's VCF to add names.
2. Search not finding? FTS5 uses word boundaries. Use * for prefix matching: Bas* matches "Bashar".
3. Large exports? ChatGPT exports can be 50MB+. First import may take 30-60 seconds.
