Spillwave Second Brain Marketplace

One Claude Code marketplace for the eight job-function ContentPack plugins plus core. Each plugin writes OKF Markdown + YAML into the same knowledge/ tree. Grok Bots, Claude Code, Codex, Deep Agents, and local laptop jobs share that tree.

MIT. Multi-host: Claude Code, Grok Build, Codex, Cursor, Agent Plugins 1.0, Grok Bot, LangChain Deep Agents.

Already installed? Refresh pins

Claude Code caches the marketplace snapshot. /plugin Available can lag GitHub, and In use stays on the version you originally installed until you update.

After this catalog (0.4.6) the foundation Available pins are:

Pack	Pin
okf-graph-eng	0.8.2
project-knowledge-capture	0.9.1
system-architecture-capture	0.5.3
data-engineering-knowledge-capture	0.5.0
okf-agent-graph	0.7.1

/plugin marketplace update SpillwaveSolutions/second-brain-marketplace
/plugin update okf-graph-eng@spillwave-second-brain
/plugin update project-knowledge-capture@spillwave-second-brain
/plugin update system-architecture-capture@spillwave-second-brain
/plugin update data-engineering-knowledge-capture@spillwave-second-brain
/plugin update okf-agent-graph@spillwave-second-brain

Existing graphs that still have domain nouns in the engine, or data jobs typed Workflow: noun-ownership migration.

Cursor (including Grok Bot cloud agents):

/plugin marketplace add SpillwaveSolutions/second-brain-marketplace
/plugin install content-media

Each pack ships .cursor-plugin/plugin.json and docs/CURSOR.md. A Cursor session opened on the knowledge tree still follows the write protocol even without a plugin install.

Use the public starter for fiction-only samples:

git clone https://github.com/SpillwaveSolutions/second-brain-starter.git

Point every plugin at your existing local knowledge/ folder. This marketplace never names a private remote. Concurrent writers on different machines should open an isolation session (brain_session.py open) so writes land as PRs. See second-brain-core docs/ISOLATION.md.

Plugins

Plugin	Agent identity	What it writes
second-brain-core	grok-bot/second-brain-core	Shared OKF schemas, typed edges, deterministic write helpers, isolation, ContextPack engine.
executive-coordination	grok-bot/executive-coordination	Chief-of-staff ContentPack: priorities, decisions, blockers, digests, handoffs.
account-management	grok-bot/account-management	Account and relationship ContentPack: clients, contacts, plans, deliverables, renewals.
sales-pipeline	grok-bot/sales-pipeline	Sales pipeline ContentPack: leads, opportunities, stages, objections, forecasts.
executive-job-search	grok-bot/executive-job-search	Executive job-search ContentPack: job leads, roles, interviews, offers, criteria.
consulting-leads	grok-bot/consulting-leads	Inbound consulting-lead ContentPack: engagement types, discovery, scopes, qualification.
content-media	grok-bot/content-media	Content and audience ContentPack: articles, drafts, series, subscribers, metrics.
news-digest	grok-bot/news-digest	News digest ContentPack: items, sources, scheduled digests, trends, follow-up candidates.
gtm-positioning	grok-bot/gtm-positioning	Go-to-market ContentPack: offers, positioning, ICPs, campaigns, battle cards.

How the pieces fit

Grok Bot: Articles  ──writes──►  knowledge/articles/     (session worktree + PR)
Grok Bot: Sales     ──writes──►  knowledge/sales-leads/
Laptop job (Codex)  ──writes──►  knowledge/   (same tree)
Claude Code         ──packs───►  bounded ContextPack (2 hops / ~20 nodes)
Deep Agents         ──skills──►  same scripts, same isolation

Rules:

1. The model proposes. Schema-enforced scripts commit.
2. An agent never invents rel values and never writes types it does not own.
3. Progressive disclosure. Pack from a root. Do not dump the whole tree.
4. Samples use the fictional Northstar account and Lumenfield employer. No real client names.
5. Concurrent writers isolate via worktree + PR. They do not share one mutable main tip.

Foundation plugins (now in this marketplace)

Install the engineering substrate the same way as a job pack. These pins are the 30 Aug 2026 retrieval-ladder cut.

Plugin	Repo	Pin
okf-graph-eng	okf-plugin	0.8.2
project-knowledge-capture	project-knowledge-capture	0.9.1
system-architecture-capture	system-architecture-capture	0.5.3
data-engineering-knowledge-capture	data-engineering-knowledge-capture	0.5.0
okf-agent-graph	okf-agent-graph	0.7.1
worklog	wiki_ticket_sdd	0.24.4

Onboarding a Grok Bot

Each plugin now ships docs/ONBOARDING.md. Give a new Grok Bot that file first. It covers:

• History of the LLM-wiki / second-brain effort (OKF, WikiTicket, PKC, SAC, DEKC, AGER, ContentPacks)
• Destination state: cloud Grok Bots and local laptop agents reading and writing the same git-native tree
• Identity, isolation, deterministic write boundary, progressive disclosure
• Every public repository in this suite plus the foundation layer

Start with second-brain-core docs/ONBOARDING.md.
