CaBrain brains — FlowOS & AVO
CaBrain hosts multiple namespaces ("brains"):
flowos— the FlowOS / OneStudio hub (below).avo(~2,490 memories) — the AVO "Founder Readiness Lab" repo (onestudio-exp/AVO) markdown: 359 files chunked by heading (board pack, playbooks, kaizen engine, kickstart legal/finance, pitch/fundraising, research, theses, drills). Re-run withscratchpad/avoingest.py(needs the repo cloned toscratchpad/AVOviagh repo clone onestudio-exp/AVO). Query withmemory_recall(namespace="avo", query="…").
The FlowOS brain — querying CaBrain about ventures & people
CaBrain has ingested the FlowOS (OneStudio hub) knowledge into the flowos
namespace so any MCP-connected session can ask about a venture, agent, person,
learning, or lean canvas and get the answer back from memory.
What's ingested (namespace flowos, ~1,780 memories)
Two passes: the FlowOS MCP (structured API) and the full hub Postgres DB
(onestudio_hub, via an SSH tunnel) — everything except high-frequency telemetry
(feature/transition/claude-activity events, github metrics, views, tokens).
| Type | Source |
|---|---|
| Ventures (66, full records + team) | DB ventures + MCP get_venture |
| Domain-expert agents (40, en+ar, skills) | DB agents + MCP get_agent |
| People (46, names/emails/roles + venture memberships) | DB users + venture_members |
| Issues (597 — title, description, status, priority) | DB issues |
| Posts / status feed (930) | DB posts |
| Learnings (178) | MCP list_learnings + DB |
| Lean canvases (57) | MCP get_lean_canvas |
| Roadmaps (178), Releases (69), Goals (222), Harvested research (82), Tasks (68) | DB |
Near-duplicate/templated rows collapse via the §4.1 write-decision (that's why the
row total is ~1,780, not the raw ~2,600). Each memory embeds via TEI (bge-m3) and is
recallable by vector + BM25 + rerank. Re-run / extend with scratchpad/ingest.py,
enrich.py, and dbingest.py (the DB pass needs the SSH tunnel:
ssh -L 15432:<DB_HOST>:5432 <USER>@<JUMP_HOST> — real host/creds held by the owner).
How to query it (from a new Claude Code session)
The cabrain MCP server is wired in .mcp.json (stdio, brain-mcp, talks to the
app on localhost:8080). After restarting Claude Code so it loads, the agent has
these tools: memory_recall, memory_retain, memory_get, memory_forget,
memory_share, memory_recall_archive.
Ask with memory_recall, namespace flowos:
Verified live: "Sentra" → Sentra, "Zeedly embedded Salla app" → Zeedly, "PDPL Saudi data protection" → PDPL Starter Kit, "football scouting in Saudi Arabia" → Akhdar, "permission-check learning" → the exact learning.
Running / restarting the app
The app must be up for the brain MCP to reach it. It runs detached:
run-cabrain.sh sets DATABASE_URL (from CABRAIN_DATABASE_URL), the TEI/Cognee
URLs, CACHE_DRIVER=redis, and BRAIN_BM25_TOKENIZER. The workspace must be on
stack_stacknet (sudo docker network connect stack_stacknet coder-… on the WSL
host) so pg/tei-embed/cognee/redis resolve.
Optionally add the live FlowOS MCP (not committed — has a token)
To also give the session live FlowOS hub tools, add this to a non-committed
config (~/.claude.json user scope), NOT the repo .mcp.json:
Two follow-ups that sharpen the brain (infra)
- Production BM25 tokenizer — name/keyword recall is strongest with a real
multilingual tokenizer. A superuser runs
infra/grant-bm25.sql§3 to createcabrain_ml(llmlingua2), then setBRAIN_BM25_TOKENIZER=cabrain_ml. - Cognee graph — cognify currently fails with "Missing required pgvector
credentials" (Cognee's own vector store isn't configured). Once infra sets
Cognee's pgvector creds,
brainctl mirror flowospopulates the entity graph + Graph Explorer.
