Open-source second-brain-os packs 18 agent skills and 72 slash commands into Claude Code + Obsidian
blaizedsouza · x · 2026-10-06
The open-source second-brain-os repo turns Obsidian, Claude Code and an LLM into a self-maintaining AI second brain in plain markdown you own.
- Guide: 65 pages across 10 sections, plus 44 pages of tracks, 15 of them build guides with working code
- The machine (.claude/): 18 agent skills, 72 slash commands (/ingest-pdf, /ingest-youtube, /ingest-voice, /backfill), and 6 subagents (curator, linker, researcher, reviewer, ingestor, graph-analyst), 4 of them read-only so nothing rewrites your vault
- Scripts: plain Python, zero dependencies — graph export, link checker, vault stats, site builder
- Starter vault: its own CLAUDE.md with page contracts and linking rules; raw/ stays untouched once ingested
The companion article frames the stack as Hermes (agent) + MiniMax M3 (reasoning) + Obsidian (memory) merged into one feedback loop.
