Shared foundation for Spillwave ContentPack plugins: OKF schemas, typed edges, deterministic write helpers, and progressive-disclosure packing. Dual-host (Claude Code + Grok Build + Codex).
MIT. Dual-host: Claude Code, Grok Build, and Codex (Agent Skill Standard). Writes OKF Markdown + YAML into a shared second-brain bundle so other agents and local jobs can read the same graph.
# Claude Code
/plugin marketplace add SpillwaveSolutions/second-brain-core
/plugin install second-brain-core@SpillwaveSolutions
# Skilz CLI
skilz install SpillwaveSolutions/second-brain-corePoint the plugin at a shared knowledge root (default knowledge/). All sibling ContentPack plugins write into the same tree.

The model proposes. Schema-enforced scripts commit:
python3 scripts/sbc_common.py write \
--bundle knowledge \
--type Concept \
--folder concepts \
--title "Example" \
--author "Grok Bot: Second Brain Core"Never invent rel values. Never write types owned by another plugin.
This plugin is the shared substrate. Domain plugins (sales-pipeline, content-media, …) depend on these write and pack conventions.

Grok Bot and other host agents should start at docs/ONBOARDING.md. That file is the history of the LLM-wiki effort, the destination state (Grok Bots and local agents sharing one git-native second brain), and the canonical public repo list.
Works with Claude Code, Grok Build, Codex, Agent Plugins 1.0 clients, Grok Bot, and LangChain Deep Agents.
| Host | How to load |
|---|---|
| Claude Code | marketplace + plugin install |
| Grok Build | zero-config Claude plugin |
| Codex | Agent Skills / hooks/hooks.json |
| Agent Plugins clients | root plugin.json + skills/ |
| Grok Bot | docs/GROK_BOT.md |
| LangChain Deep Agents | docs/LANG_CHAIN_DEEP_AGENTS.md |
Write isolation (worktree + PR) lives in second-brain-core: docs/ISOLATION.md. Point SECOND_BRAIN_ROOT at the session bundle. Never hard-code a private remote.
Eight job-function plugins plus core. Knowledge root is always a local path or env the human already owns.
