Capture Skill

Purpose

Parse and structure information from screen captures, meeting notes, conversations, or any text input, then store it in the Second Brain Supabase database.

When Claude Should Use This

• User provides a screenshot with information to save
• User pastes meeting notes or conversation transcript
• User describes something they want to remember
• User shares ideas, tasks, or contact information
• User says "save this", "capture this", "remember this"

How It Works

Step 1: Receive Input

Accept any of:

• Screenshot description or OCR text
• Pasted text (emails, notes, messages)
• Verbal description of information
• Mixed content (text + context)

Step 2: Intelligent Parsing

Analyze the content and extract:

Contacts (people mentioned) - Extract rich, structured information:

Name Fields:

• first_name, last_name, middle_name (parse from full name)
• preferred_name (nicknames, how they like to be addressed)
• prefix (Mr., Mrs., Dr., Prof.)
• suffix (Jr., Sr., PhD, MD, III)

Contact Methods:

• primary_email, secondary_email (validate format)
• primary_phone + country_code + type (mobile/work/home)
• secondary_phone + country_code + type

Location:

• city, state_province, country
• timezone (ALWAYS infer from location + country if possible; e.g., San Francisco → America/Los_Angeles, London → Europe/London, Sydney → Australia/Sydney)
• address (if provided)

LLM-Driven Enrichment (Automatic via MCP, But Provide Good Context):

• Country Inference from Phone Code: If phone has +56 but no country → Will infer "Chile"; if +44 → "United Kingdom"; if +1 → "USA". Action: Always include country code in phone numbers
• Timezone Inference from City+Country: Santiago+Chile → America/Santiago; Tokyo+Japan → Asia/Tokyo; London+UK → Europe/London. Action: Include both city AND country for accurate timezone
• Industry Inference from Context: From company name, title, or keywords like "SaaS", "biotech", "fintech", "finance", "healthcare", "tech", "real estate", "manufacturing"
• Company Size Inference from Context: Keywords like "startup", "Series A/B/C", "Fortune 500", "enterprise", "5000+ employees"
• Seniority Inference from Title: CEO/CTO/CFO → C-Level; Director/VP → Executive; Manager/Senior → Mid/Senior; Engineer/Analyst → Entry

Professional:

• company, title, department
• industry (tech, finance, healthcare, etc.) - Will be inferred from company/title if not explicitly stated
• seniority_level (Entry, Mid, Senior, Executive, C-Level) - Will be inferred from title if not explicitly stated
• company_size (Startup, Small, Medium, Enterprise) - Will be inferred from context if not explicitly stated

Social/Online:

• linkedin_url (validate LinkedIn format)
• twitter_handle, github_username, website

Relationship Context:

• persona: client/prospect/vendor/partner/colleague/friend/family
• relationship_strength: cold/warm/hot/champion
• how_we_met (conference, intro from X, school, etc.)
• referral_source (who introduced you)
• interests[], skills[] (array of relevant tags)

Tasks (action items)

• What needs to be done
• Priority (urgent, high, medium, low)
• Due date (if mentioned)
• Who it's for/related to
• Category (work, personal, follow-up, etc.)

Ideas (insights, notes, thoughts)

• Main concept or insight
• Supporting details
• Category (business, technical, personal, creative)
• Related contacts or projects
• Tags for organization

Opportunities (job leads, partnerships, investments, etc.)

• Organization and role/description
• Status (identified, researching, applied, in_progress, etc.)
• Category (full_time, contract, consulting, advisory, investment, partnership, grant, etc.)
• Deadline and urgency
• Location (region, country, city, remote options)
• Compensation (salary range, equity, benefits)
• Scoring:
  • Strategic value (0-10 + weight)
  • Personal fit (0-10 + weight)
  • Feasibility (0-10 + weight)
  • Trusted peer score
• Network mapping:
  • Primary contacts (1st degree connections)
  • Secondary contacts (2nd degree)
  • Relevant networks
• Assessment: "Can I realistically get this?"
• Priority: Critical, High, Medium, Low
• Context: Why interested, concerns, next steps

Raw Capture

• Always save the complete original content
• Note the source type (screenshot, text, voice, etc.)
• Timestamp automatically

Step 3: Store in Supabase

Use the Supabase MCP to store data in appropriate tables:

1. captured_items table (always first)

   - raw_content: Full original text
   - content_type: 'text', 'screenshot', 'voice', 'paste'
   - source: 'claude_desktop'
   - status: 'processing'
   

2. contacts table (if people identified)

   ALWAYS check for duplicates first (search by email or full name)
   
   Name fields:
   - first_name, last_name, middle_name (parsed)
   - preferred_name, prefix, suffix
   
   Contact methods:
   - primary_email (required if available)
   - primary_phone, primary_phone_country_code, primary_phone_type
   - secondary_email, secondary_phone (if mentioned)
   
   Location:
   - city, state_province, country (USE CLAUDE'S REASONING TO INFER)
   - timezone (ALWAYS INFER from location + country; see enrichment section above)
   
   Professional:
   - company, title, department
   - industry (USE CLAUDE'S REASONING: infer from context; e.g., "works at VC firm" → finance, "biotech startup" → healthcare)
   - seniority_level (USE CLAUDE'S REASONING: infer from title; CEO/CTO/CFO → C-Level, Director/VP → Executive)
   - company_size (USE CLAUDE'S REASONING: infer from context; startup, Series A, Fortune 500 → Enterprise)
   
   Social:
   - linkedin_url, twitter_handle, github_username, website
   
   Relationship:
   - persona (client/prospect/vendor/partner/colleague/friend/family)
   - relationship_strength (cold/warm/hot/champion based on context)
   - contact_status (default: 'active')
   - how_we_met, referral_source
   - interests[] (e.g., ['AI', 'photography', 'hiking'])
   - skills[] (e.g., ['Python', 'leadership', 'design'])
   
   Tracking:
   - first_contact_date (today if new contact)
   - next_followup_date (if mentioned in capture)
   
   Context:
   - notes: Free-form context from capture
   - metadata: {source: 'linkedin', source_capture_id: ...}
   
   ENRICHMENT BEST PRACTICES:
   - If phone has +56, infer country: Chile
   - If phone has +44, infer country: United Kingdom
   - If city: "Santiago", infer country: Chile, timezone: America/Santiago
   - If no country stated but phone + country_code present, always fill in country field
   - Use your reasoning to fill in seniority_level, industry, company_size from available context
   

3. tasks table (if action items found)

   - title: Brief description of task
   - description: Full details
   - priority: Based on urgency cues
   - status: 'pending'
   - due_date: Parse from text if present
   - source_capture_id: Link to captured_item
   

4. ideas table (if insights/notes present)

   - title: Main concept
   - content: Full details
   - category: Inferred from context
   - tags: Array of relevant keywords
   - source_capture_id: Link to captured_item
   

5. opportunities table (if job/opportunity mentioned)

Error Handling

If parsing unclear:

1. Save to captured_items with status='pending'
2. Ask user for clarification
3. Don't guess - it's better to ask

If duplicate contact found:

1. Ask if it's the same person
2. Offer to update existing or create new
3. Merge information if user confirms

If Supabase error:

1. Show the error clearly
2. Save content locally/clipboard as backup
3. Suggest manual retry

Best Practices

1. Always save raw content first - Never lose the original
2. Be conservative with parsing - When in doubt, ask user
3. Link everything - Use source_capture_id to maintain relationships
4. Provide clear feedback - User should know exactly what was saved
5. Handle duplicates gracefully - Check before creating new contacts
6. Preserve context - Include where/when/how information was captured
7. Use tags liberally - Better to have more tags than fewer
8. Infer relationships - Connect tasks to contacts when relevant

Security Notes

• Never store sensitive data like passwords or API keys
• Warn user if SSN, credit card numbers detected
• Ask before storing financial or health information
• Respect user privacy - all data is user-owned

Future Enhancements (Not Yet Implemented)

• Voice transcription support
• Image OCR for screenshots
• Smart scheduling (Google Calendar integration)
• Duplicate detection with similarity matching
• Auto-categorization using AI models
• Relationship mapping between entities
