What problem does this solve?
Turns your personal knowledge and team operations into a self-evolving system powered by AI agents. Rather than storing isolated notes in a note-taking app or managing team activity across disconnected tools, COG captures thoughts into structured markdown, derives intelligence through systematic analysis, learns your patterns, and syncs reality back to your source systems. No vendor lock-in, no database, no subscriptions. Just .md files that think.
How does it work?
- Clone the repo, run onboarding in your AI agent (2 minutes). 2. Use skills daily: braindump raw thoughts, get daily news briefings, process team activity across GitHub, Linear, and Slack. 3. Weekly reflection consolidates patterns and plans next steps. 4. Long-term: braindumps feed into strategic research and knowledge frameworks. Output: markdown vault containing your evolving personal and team intelligence, synced back to GitHub, Linear, and Slack.

Set Up, Update & Maintain COG19 skills
Framework skills for onboarding new users, updating COG, and architectural patterns for skill design (loop engineering, scout).
What's the biggest win?
Every piece of intelligence (personal, team, product) lives in one versioned vault and can flow between tools without re-entry. Team activity stays synced across GitHub, Linear, and Slack. You review patterns others miss because they are trapped in separate systems.
What's required to run this?
Works with Node 18+ for CLI tools (gh for GitHub, linear for Linear API). Requires API keys for external services (optional but recommended: GitHub, Linear, Slack, PostHog). Runs locally with no external servers. Optional iCloud sync for mobile access. All data remains in your vault (.md files plus Git for version control).
What should I watch out for?
Team intelligence skills (team-brief, meeting-transcript, comprehensive-analysis) require integrations (GitHub CLI, Linear, Slack, PostHog) and work best with those tools configured. They degrade gracefully to GitHub alone, but full power requires multi-tool setup. Personal knowledge skills work standalone from day one.
