Google Drive Knowledge Bank

Meeting Notes Knowledge Bank

Transform a folder of Google Docs meeting notes into a queryable knowledge bank. This skill ingests meeting notes, parses them into structured format, and stores them for fast, accurate retrieval when answering questions.

Two-Phase Workflow

Phase 1: Ingestion (Build the Knowledge Bank)

Pull meeting notes from Google Drive, parse their content, and store as structured data.

Phase 2: Querying (Answer Questions)

Search the stored knowledge bank to answer questions accurately, always grounding responses in the actual meeting content.

Prerequisites

This skill requires the Google Workspace CLI (gws):

# Check if installed
gws --version

# If not installed
npm install -g @googleworkspace/cli

# Authenticate
gws auth login

# Verify access
gws drive files list --max-results 5

PHASE 1: INGESTION

Step 1: Get Folder ID from User

Ask the user for their meeting notes folder. They can provide:

• Folder name (you'll search for it)
• Folder ID directly
• Folder URL (extract ID from it)

Find folder by name:

gws drive files search \
  --query "name = 'Meeting Notes' and mimeType = 'application/vnd.google-apps.folder'" \
  --format json

Extract folder ID from URL: URL format: https://drive.google.com/drive/folders/FOLDER_ID

Step 2: List All Meeting Notes in Folder

# Get all Google Docs in the folder
gws drive files list \
  --parent-id "FOLDER_ID" \
  --query "mimeType = 'application/vnd.google-apps.document'" \
  --format json > /tmp/meeting_files_list.json

# Parse to see what we got
cat /tmp/meeting_files_list.json | jq -r '.files[] | "\(.name) | \(.id) | \(.modifiedTime)"'

Step 3: Export All Meeting Notes

# Create knowledge bank directory
mkdir -p /tmp/knowledge_bank

# Parse file list and export each document
FILE_IDS=($(cat /tmp/meeting_files_list.json | jq -r '.files[].id'))

for file_id in "${FILE_IDS[@]}"; do
  # Get file metadata
  FILE_NAME=$(cat /tmp/meeting_files_list.json | jq -r ".files[] | select(.id == \"$file_id\") | .name")
  MODIFIED=$(cat /tmp/meeting_files_list.json | jq -r ".files[] | select(.id == \"$file_id\") | .modifiedTime")
  
  # Export as plain text
  echo "Ingesting: $FILE_NAME"
  gws drive files export \
    --file-id "$file_id" \
    --mime-type "text/plain" \
    --output-file "/tmp/knowledge_bank/${file_id}.txt"
  
  # Store metadata
  echo "$file_id|$FILE_NAME|$MODIFIED" >> /tmp/knowledge_bank/metadata.txt
done

echo "✓ Ingested ${#FILE_IDS[@]} meeting notes"

Step 4: Parse and Structure Content

For each meeting note, extract structured information:

# Create parsed knowledge base
mkdir -p /tmp/knowledge_bank/parsed

for file in /tmp/knowledge_bank/*.txt; do
  if [ "$file" = "/tmp/knowledge_bank/metadata.txt" ]; then
    continue
  fi
  
  FILE_ID=$(basename "$file" .txt)
  
  # Read full content
  CONTENT=$(cat "$file")
  
  # Parse metadata from content (filename pattern: "Meeting Type - YYYY-MM-DD")
  METADATA=$(grep "$FILE_ID" /tmp/knowledge_bank/metadata.txt)
  FILE_NAME=$(echo "$METADATA" | cut -d'|' -f2)
  MODIFIED=$(echo "$METADATA" | cut -d'|' -f3)
  
  # Extract meeting date from filename if present
  MEETING_DATE=$(echo "$FILE_NAME" | grep -oE '[0-9]{4}-[0-9]{2}-[0-9]{2}' || echo "unknown")
  
  # Create structured JSON entry
  cat > "/tmp/knowledge_bank/parsed/${FILE_ID}.json" <<EOF
{
  "file_id": "$FILE_ID",
  "filename": "$FILE_NAME",
  "meeting_date": "$MEETING_DATE",
  "modified_time": "$MODIFIED",
  "content": $(echo "$CONTENT" | jq -Rs .),
  "word_count": $(echo "$CONTENT" | wc -w),
  "indexed_at": "$(date --iso-8601=seconds)"
}
EOF

done

echo "✓ Parsed and structured all meeting notes"

Step 5: Create Search Index

Build a searchable index with keywords:

# Create index file
echo "# Meeting Notes Knowledge Bank Index" > /tmp/knowledge_bank/INDEX.md
echo "Generated: $(date)" >> /tmp/knowledge_bank/INDEX.md
echo "" >> /tmp/knowledge_bank/INDEX.md

# List all meetings
echo "## Meetings Indexed" >> /tmp/knowledge_bank/INDEX.md
echo "" >> /tmp/knowledge_bank/INDEX.md

for json_file in /tmp/knowledge_bank/parsed/*.json; do
  FILE_NAME=$(jq -r '.filename' "$json_file")
  MEETING_DATE=$(jq -r '.meeting_date' "$json_file")
  WORD_COUNT=$(jq -r '.word_count' "$json_file")
  FILE_ID=$(jq -r '.file_id' "$json_file")
  
  echo "- **$FILE_NAME** ($MEETING_DATE) - $WORD_COUNT words - ID: $FILE_ID" >> /tmp/knowledge_bank/INDEX.md
done

echo "" >> /tmp/knowledge_bank/INDEX.md
echo "Total meetings: $(ls /tmp/knowledge_bank/parsed/*.json | wc -l)" >> /tmp/knowledge_bank/INDEX.md

cat /tmp/knowledge_bank/INDEX.md

Step 6: Confirm Ingestion Complete

echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "✓ KNOWLEDGE BANK READY"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "Location: /tmp/knowledge_bank/"
echo "Meetings indexed: $(ls /tmp/knowledge_bank/parsed/*.json | wc -l)"
echo "Ready to answer questions!"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"

Tell the user: "I've ingested and indexed your meeting notes. You can now ask me questions about them!"

PHASE 2: QUERYING

When User Asks a Question

Always follow this workflow:

1. Check if knowledge bank exists
2. Search the knowledge bank for relevant meetings
3. Read full content of relevant meetings
4. Extract answer grounded in the actual text
5. Cite sources with meeting name and date

Step 1: Verify Knowledge Bank Exists

if [ ! -d "/tmp/knowledge_bank/parsed" ]; then
  echo "ERROR: Knowledge bank not found. Please run ingestion first."
  exit 1
fi

if [ $(ls /tmp/knowledge_bank/parsed/*.json 2>/dev/null | wc -l) -eq 0 ]; then
  echo "ERROR: Knowledge bank is empty. Please ingest meeting notes first."
  exit 1
fi

Step 2: Search Knowledge Bank

Search by keyword in content:

# User asks: "What did we decide about API redesign?"
KEYWORD="API redesign"

# Search all parsed notes
grep -l "$KEYWORD" /tmp/knowledge_bank/*.txt 2>/dev/null | while read file; do
  FILE_ID=$(basename "$file" .txt)
  if [ -f "/tmp/knowledge_bank/parsed/${FILE_ID}.json" ]; then
    FILE_NAME=$(jq -r '.filename' "/tmp/knowledge_bank/parsed/${FILE_ID}.json")
    MEETING_DATE=$(jq -r '.meeting_date' "/tmp/knowledge_bank/parsed/${FILE_ID}.json")
    echo "Found in: $FILE_NAME ($MEETING_DATE) - ID: $FILE_ID"
  fi
done

Search by meeting date:

# User asks: "What happened in the March 1st meeting?"
TARGET_DATE="2026-03-01"

for json_file in /tmp/knowledge_bank/parsed/*.json; do
  MEETING_DATE=$(jq -r '.meeting_date' "$json_file")
  if [ "$MEETING_DATE" = "$TARGET_DATE" ]; then
    FILE_NAME=$(jq -r '.filename' "$json_file")
    FILE_ID=$(jq -r '.file_id' "$json_file")
    echo "Found: $FILE_NAME - ID: $FILE_ID"
  fi
done

Search by meeting type:

# User asks: "Show me all engineering syncs"
MEETING_TYPE="Engineering Sync"

for json_file in /tmp/knowledge_bank/parsed/*.json; do
  FILE_NAME=$(jq -r '.filename' "$json_file")
  if echo "$FILE_NAME" | grep -q "$MEETING_TYPE"; then
    MEETING_DATE=$(jq -r '.meeting_date' "$json_file")
    FILE_ID=$(jq -r '.file_id' "$json_file")
    echo "Found: $FILE_NAME ($MEETING_DATE) - ID: $FILE_ID"
  fi
done

Step 3: Read Full Content

Once you've identified relevant meetings, read their FULL content:

# Read from parsed JSON
CONTENT=$(jq -r '.content' "/tmp/knowledge_bank/parsed/${FILE_ID}.json")

echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "Reading: $(jq -r '.filename' "/tmp/knowledge_bank/parsed/${FILE_ID}.json")"
echo "Date: $(jq -r '.meeting_date' "/tmp/knowledge_bank/parsed/${FILE_ID}.json")"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "$CONTENT"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"

Step 4: Extract and Synthesize Answer

CRITICAL RULES:

• ✅ Only state what's explicitly in the meeting notes
• ✅ Quote or paraphrase directly from the content
• ✅ Cite which meeting(s) the information came from
• ✅ Include meeting date in citation
• ❌ NEVER make up information
• ❌ NEVER infer beyond what's written
• ❌ NEVER claim something was discussed if it's not in the notes

Response Format:

**Answer**: [Direct answer from meeting content]

**Source**: [Meeting Name] - [Meeting Date]

**Full Context**: [Relevant excerpt from notes]

**File ID**: [file_id for reference]

Step 5: Handle Multi-Meeting Synthesis

If multiple meetings discuss the topic:

# Find all relevant meetings
RELEVANT_IDS=()
for file in /tmp/knowledge_bank/*.txt; do
  if grep -q "$KEYWORD" "$file"; then
    FILE_ID=$(basename "$file" .txt)
    RELEVANT_IDS+=("$FILE_ID")
  fi
done

echo "Found ${#RELEVANT_IDS[@]} meetings discussing '$KEYWORD'"

# Read and synthesize
for file_id in "${RELEVANT_IDS[@]}"; do
  FILE_NAME=$(jq -r '.filename' "/tmp/knowledge_bank/parsed/${file_id}.json")
  MEETING_DATE=$(jq -r '.meeting_date' "/tmp/knowledge_bank/parsed/${file_id}.json")
  CONTENT=$(jq -r '.content' "/tmp/knowledge_bank/parsed/${file_id}.json")
  
  echo "═══════════════════════════════════════════════"
  echo "$FILE_NAME - $MEETING_DATE"
  echo "═══════════════════════════════════════════════"
  echo "$CONTENT"
  echo ""
done

Then synthesize across all meetings chronologically.

Query Patterns

Pattern 1: Specific Decision Lookup

User: "What was decided about pricing?"

Workflow:
1. Search for "pricing" in all meeting notes
2. Find matching meetings
3. Read full content
4. Extract decision statements
5. Cite source meeting(s)

Pattern 2: Timeline/Progression

User: "How did the API discussion evolve?"

Workflow:
1. Search for "API" across all notes
2. Sort matches by meeting date
3. Read each in chronological order
4. Show progression of discussion
5. Cite each meeting in timeline

Pattern 3: Action Items

User: "What are my action items?"

Workflow:
1. Search for "action" OR "@" OR "TODO" across notes
2. Extract lines mentioning user's name
3. Group by meeting
4. List with source and date

Pattern 4: Topic Summary

User: "Summarize discussions about hiring"

Workflow:
1. Search for "hiring" OR "recruitment" across notes
2. Read all matching meetings
3. Synthesize key points
4. Cite each source

Maintenance Operations

Refresh Knowledge Bank

When new meetings are added:

# Re-run ingestion to pull new notes
# It will overwrite existing files with same ID
# New files will be added

Check Knowledge Bank Status

echo "Knowledge Bank Status:"
echo "Location: /tmp/knowledge_bank/"
echo "Total meetings: $(ls /tmp/knowledge_bank/parsed/*.json 2>/dev/null | wc -l)"
echo "Last updated: $(stat -c %y /tmp/knowledge_bank/INDEX.md 2>/dev/null)"
echo ""
echo "Recent meetings:"
ls -t /tmp/knowledge_bank/parsed/*.json | head -5 | while read file; do
  jq -r '"\(.filename) - \(.meeting_date)"' "$file"
done

Search Statistics

# Show most common keywords
cat /tmp/knowledge_bank/*.txt | tr '[:space:]' '\n' | \
  tr '[:upper:]' '[:lower:]' | \
  grep -v '^$' | \
  sort | uniq -c | sort -rn | head -20

Error Handling

No Knowledge Bank

if [ ! -d "/tmp/knowledge_bank" ]; then
  echo "⚠ Knowledge bank not initialized."
  echo "Please run: 'ingest my meeting notes from [folder]'"
  exit 1
fi

No Matches Found

if [ ${#RELEVANT_IDS[@]} -eq 0 ]; then
  echo "No meetings found discussing '$KEYWORD'"
  echo ""
  echo "Try:"
  echo "  - Alternative keywords"
  echo "  - Broader search terms"
  echo "  - Checking meeting date range"
  echo ""
  echo "Available meetings:"
  cat /tmp/knowledge_bank/INDEX.md | grep "^- "
fi

Partial Information

"I found partial information about X in the [date] meeting, but the 
discussion appears incomplete. The notes mention [what's there] but 
don't include [what's missing]."

# ═══════════════════════════════════════════════════

User: "What was decided about the Q2 roadmap?"

Claude:
$ grep -l "Q2 roadmap" /tmp/knowledge_bank/*.txt
# Found in 3 meetings

$ # Reading Engineering Sync - 2026-02-15
$ jq -r '.content' /tmp/knowledge_bank/parsed/file123.json

$ # Reading Product Planning - 2026-02-20

$ # Reading All Hands - 2026-03-01
$ jq -r '.content' /tmp/knowledge_bank/parsed/file789.json

**Answer**: The Q2 roadmap was finalized with three priorities:
1. Mobile app redesign (priority #1)
2. API v2 launch (priority #2)  
3. Analytics dashboard (moved to Q3)

**Sources**: 
- Engineering Sync - February 15, 2026
- Product Planning - February 20, 2026
- All Hands - March 1, 2026

**Timeline**:
- Feb 15: Initial proposal discussed
- Feb 20: Priorities debated, mobile chosen as #1
- Mar 1: Final roadmap announced to company

**Key Decision**: Analytics dashboard deprioritized due to 
resource constraints (noted in Feb 20 meeting).
