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.
Included Skill Groups
Get Daily Intelligence Briefings9 skills
Skills that generate personalized daily news, team activity, and weekly reflections with verified sources and cross-referenced insights.
Lead Teams With Cross-System Intelligence13 skills
Skills for team leads and product managers that synthesize GitHub, Linear, Slack, meeting notes, and metrics into coherent team intelligence.
Run Product Workflows End to End8 skills
Complete product lifecycle skills: research, PRD generation, user story creation, issue tracking, release notes, and knowledge base updates.
Conduct Deep Strategic Research4 skills
A single skill for decomposing complex research questions into parallel investigation threads with multi-agent architecture and cited sources.
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 should I know technically?
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.
Key Features
19 Skills
Modular skills for personal capture, intelligence synthesis, team tracking, and product workflows. Run individually or chained together.
Multi-Agent Support
Works with Claude Code, Cursor, Kiro, Gemini CLI, OpenAI Codex, or any markdown-reading agent. Choose your AI agent. COG adapts to it.
Worker Agent Architecture
Specialist sub-agents (data-collector, researcher, executor) handle heavy lifting in parallel, with Opus as orchestrator. Fast, efficient, and scalable.
Self-Healing Vault
Markdown-based organization stays consistent across tool changes. Cross-references update automatically when files are renamed or restructured.
Two-Way Sync
Daily brief syncs intelligence back to Linear, GitHub, and Slack. Team activity feeds into your personal intelligence system without duplication.
