Install Digital Brain

Pick your agent. Every command is ready to paste.

$npx skills add muratcankoylan/Agent-Skills-for-Context-Engineering --skill digital-brain

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads digital-brain when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the digital-brain skill”. In Codex, type $digital-brain.

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:

Level When Loaded Content
L1: Metadata Always This SKILL.md overview
L2: Module Instructions On-demand [module]/[MODULE].md files
L3: Data Files As-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.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

Tips for Digital Brain

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • This skill ships scripts. Read them before the first run, and run it in a project without secrets first.
  • • It bundles reference files. The agent reads them only when needed, so they cost no context until then.
  • • It is part of a pack with 24 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
