SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Managing personal brand voice, content pipelines, relationships, and goals across scattered notes and tools leads to inconsistent output and lost context. This Skill provides a structured, file-based personal operating system that AI agents can navigate with minimal token usage. ## Core Features & Use Cases - Voice-Consistent Content Creation: Reads identity/voice.md before drafting posts, threads, or newsletters so output matches your authentic style. - Personal CRM: Tracks contacts, interaction history, and relationship tiers in append-only JSONL files for meeting prep and follow-ups. - Goal & Productivity Tracking: Manages todos with P0-P3 priorities, OKRs in YAML, and weekly reviews via automation scripts. - Use Case: Ask your AI assistant to "prepare me for my call with Sarah" and it compiles a brief from contacts.jsonl, interactions.jsonl, and pending todos—loading only ~390 tokens instead of your entire knowledge base. ## Quick Start Install the skill into your Claude Code skills directory, fill in identity/voice.md with your writing style, then ask the agent to write a post in your voice.

Frequently Asked Questions about digital-brain

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make AI-generated content match my writing voice?▼

Fill in identity/voice.md with your tone, signature phrases, and words to avoid. The agent reads this file before drafting any content, then checks brand.md to confirm the topic aligns with your content pillars.

How do I install the digital-brain skill in Claude Code?▼

Clone the repository into ~/.claude/skills/digital-brain for user-wide access, or into .claude/skills/digital-brain for a single project. Claude Code discovers the SKILL.md file automatically.

What file formats does this personal knowledge system use?▼

It uses JSONL for append-only logs like contacts and posts, YAML for structured configs like goals and values, Markdown for narrative content like voice and todos, and XML for complex prompt templates.

Can I use this system with AI tools other than Claude Code?▼

Yes, the system is platform-agnostic since it relies on plain files and folders. Any AI assistant that can read Markdown, JSONL, and YAML files can follow the module instructions, though SKILL.md discovery is Claude Code specific.

Why does the system use append-only JSONL instead of a database?▼

Append-only JSONL preserves full history for pattern analysis, streams line-by-line without full file parsing, and works with grep. Entries are archived via a status field rather than deleted, and no database server or dependencies are required.
