Digital Brain

A structured personal operating system for managing digital presence, knowledge, relationships, and goals with AI assistance. Designed for founders building in public, content creators growing their audience, and tech-savvy professionals seeking AI-assisted personal management.

Important: This skill uses progressive disclosure. Module-specific instructions are in each subdirectory's

.md

When to Activate

Activate this skill when the user:

• Requests content creation (posts, threads, newsletters) - load identity/voice.md first
• Asks for help with personal brand or positioning
• Needs to look up or manage contacts/relationships
• Wants to capture or develop content ideas
• Requests meeting preparation or follow-up
• Asks for weekly reviews or goal tracking
• Needs to save or retrieve bookmarked resources
• Wants to organize research or learning materials

Trigger phrases: "write a post", "my voice", "content ideas", "who is [name]", "prepare for meeting", "weekly review", "save this", "my goals"

Core Concepts

Progressive Disclosure Architecture

The Digital Brain follows a three-level loading pattern:

[module]/[MODULE].md

.jsonl

.yaml

.md

File Format Strategy

Formats chosen for optimal agent parsing:

• JSONL (

  .jsonl

  ): Append-only logs - ideas, posts, contacts, interactions
• YAML (

  .yaml

  ): Structured configs - goals, values, circles
• Markdown (

  .md

  ): Narrative content - voice, brand, calendar, todos
• XML (

  .xml

  ): Complex prompts - content generation templates

Append-Only Data Integrity

JSONL files are append-only. Never delete entries:

• Mark as

  "status": "archived"

  instead of deleting
• Preserves history for pattern analysis
• Enables "what worked" retrospectives

├── identity/     → Voice, brand, values (READ FIRST for content)
├── content/      → Ideas, drafts, posts, calendar

Identity Module (Critical for Content)

Always read

identity/voice.md

Contains:

• voice.md

  - Tone, style, vocabulary, patterns

• brand.md

  - Positioning, audience, content pillars

• values.yaml

  - Core beliefs and principles

• bio-variants.md

  - Platform-specific bios

• prompts/

  - Reusable generation templates

Content Module

Pipeline:

ideas.jsonl

drafts/

posts.jsonl

• Capture ideas immediately to

  ideas.jsonl

• Develop in

  drafts/

  using

  templates/

• Log published content to

  posts.jsonl

  with metrics
• Plan in

  calendar.md

Network Module

Personal CRM with relationship tiers:

• inner

  - Weekly touchpoints

• active

  - Bi-weekly touchpoints

• network

  - Monthly touchpoints

• dormant

  - Quarterly reactivation checks

Operations Module

Productivity system with priority levels:

• P0: Do today, blocking
• P1: This week, important
• P2: This month, valuable
• P3: Backlog, nice to have

Practical Guidance

Content Creation Workflow

1. Read identity/voice.md (REQUIRED)
2. Check identity/brand.md for topic alignment
3. Reference content/posts.jsonl for successful patterns
4. Use content/templates/ as starting structure
5. Draft matching voice attributes
6. Log to posts.jsonl after publishing

Pre-Meeting Preparation

1. Look up contact: network/contacts.jsonl
2. Get history: network/interactions.jsonl
3. Check pending: operations/todos.md
4. Generate brief with context

Weekly Review Process

1. Run: python agents/scripts/weekly_review.py
2. Review metrics in operations/metrics.jsonl
3. Check stale contacts: agents/scripts/stale_contacts.py
4. Update goals progress in operations/goals.yaml
5. Plan next week in content/calendar.md

Examples

Example: Writing an X Post

Input: "Help me write a post about AI agents"

Process:

1. Read

   identity/voice.md

   → Extract voice attributes
2. Check

   identity/brand.md

   → Confirm "ai_agents" is a content pillar
3. Reference

   content/posts.jsonl

   → Find similar successful posts
4. Draft post matching voice patterns
5. Suggest adding to

   content/ideas.jsonl

   if not publishing immediately

Output: Post draft in user's authentic voice with platform-appropriate format.

Example: Contact Lookup

Input: "Prepare me for my call with Sarah Chen"

Process:

1. Search

   network/contacts.jsonl

   for "Sarah Chen"
2. Get recent entries from

   network/interactions.jsonl

3. Check

   operations/todos.md

   for pending items with Sarah
4. Compile brief: role, context, last discussed, follow-ups

Output: Pre-meeting brief with relationship context.

Guidelines

1. Voice First: Always read

   identity/voice.md

   before any content generation
2. Append Only: Never delete from JSONL files - archive instead
3. Update Timestamps: Set

   updated

   field when modifying tracked data
4. Cross-Reference: Knowledge informs content, network informs operations
5. Log Interactions: Always log meetings/calls to

   interactions.jsonl

6. Preserve History: Past content in

   posts.jsonl

   informs future performance

Integration

This skill integrates context engineering principles:

• context-fundamentals - Progressive disclosure, attention budget management
• memory-systems - JSONL for persistent memory, structured recall
• tool-design - Scripts in

  agents/scripts/

  follow tool design principles
• context-optimization - Module separation prevents context bloat
