What Digital Brain does

Digital Brain is a structured personal operating system designed to help users manage their digital presence, knowledge, relationships, and goals effectively. This skill is particularly suited for founders building in public, content creators aiming to grow their audience, and tech-savvy professionals looking for AI-assisted personal management. By leveraging a modular approach, users can activate specific functionalities as needed, ensuring a streamlined workflow tailored to their current tasks.

The skill operates on a progressive disclosure architecture, which means that it loads necessary modules and instructions on-demand. This allows users to focus on their immediate needs without being overwhelmed by the entire system at once. For example, if a user wants to create content, they would first load the identity module to align their voice and brand before proceeding to the content creation workflow. This modularity not only enhances usability but also ensures that users can maintain consistency across their digital outputs.

Digital Brain encompasses various modules, including identity, content, knowledge, network, and operations. Each module serves a specific function: the identity module helps define voice and brand, the content module assists in generating and organizing ideas, the knowledge module manages bookmarks and research, the network module acts as a personal CRM for relationships, and the operations module tracks goals and tasks. This comprehensive approach allows users to manage multiple aspects of their professional lives within a single framework, improving efficiency and clarity.

The skill also emphasizes data integrity through its use of append-only JSONL files, which preserve historical data for analysis and retrospectives. This feature is crucial for users who want to understand what strategies worked in the past and apply those insights to future endeavors. Overall, Digital Brain is an essential tool for anyone looking to enhance their personal management capabilities with the help of AI.

When to use it

Use this skill when you need assistance with content creation, relationship management, or goal tracking.

When not to use it

This skill may not be suitable for users looking for a simple note-taking app or those who do not require advanced personal management features.

What you can build with it

Content Creation

When drafting a new post, load the identity module to align your voice and brand before creating content.

Meeting Preparation

Before a call, use the network module to look up contacts and review past interactions for context.

Weekly Review

Run the weekly review script to assess your progress on goals and plan for the upcoming week.

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 file. Only load what's needed for the current task.

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:

LevelWhen LoadedContent
L1: MetadataAlwaysThis SKILL.md overview
L2: Module InstructionsOn-demand[module]/[MODULE].md files
L3: Data FilesAs-needed.jsonl, .yaml, .md data

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

Detailed Topics

Module Overview

digital-brain/
├── identity/     → Voice, brand, values (READ FIRST for content)
├── content/      → Ideas, drafts, posts, calendar
├── knowledge/    → Bookmarks, research, learning
├── network/      → Contacts, interactions, intros
├── operations/   → Todos, goals, meetings, metrics
└── agents/       → Automation scripts

Identity Module (Critical for Content)

Always read identity/voice.md before generating any content.

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.jsonldrafts/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
