GBrain

Your AI agent is smart but forgetful. GBrain gives it a brain.

Built by the President and CEO of Y Combinator to run his actual AI agents. The production brain powering his OpenClaw and Hermes deployments: 17,888 pages, 4,383 people, 723 companies, 21 cron jobs running autonomously, built in 12 days. The agent ingests meetings, emails, tweets, voice calls, and original ideas while you sleep. It enriches every person and company it encounters. It fixes its own citations and consolidates memory overnight. You wake up and the brain is smarter than when you went to bed.

The brain wires itself. Every page write extracts entity references and creates typed links (attended, works_at, invested_in, founded, advises) with zero LLM calls. Hybrid search. Self-wiring knowledge graph. Structured timeline. Backlink-boosted ranking. Ask "who works at Acme AI?" or "what did Bob invest in this quarter?" and get answers vector search alone can't reach. Benchmarked end-to-end: Recall@5 jumps from 83% to 95%, Precision@5 from 39% to 45%, +30 more correct answers in the agent's top-5 reads on a 240-page Opus-generated rich-prose corpus. Graph-only F1: 86.6% vs grep's 57.8% (+28.8 pts). Full report.

GBrain is those patterns, generalized. 26 skills. Install in 30 minutes. Your agent does the work. As Garry's personal agent gets smarter, so does yours.

~30 minutes to a fully working brain. Database ready in 2 seconds (PGLite, no server). You just answer questions about API keys.

LLMs: fetch llms.txt for the documentation map, or llms-full.txt for the same map with core docs inlined in one fetch. Agents: start with AGENTS.md (or CLAUDE.md if you're Claude Code).

Install

On an agent platform (recommended)

GBrain is designed to be installed and operated by an AI agent. If you don't have one running yet:

• OpenClaw ... Deploy AlphaClaw on Render (one click, 8GB+ RAM)
• Hermes Agent ... Deploy on Railway (one click)

Paste this into your agent:

Retrieve and follow the instructions at:
https://raw.githubusercontent.com/garrytan/gbrain/master/INSTALL_FOR_AGENTS.md

That's it. The agent clones the repo, installs GBrain, sets up the brain, loads 26 skills, and configures recurring jobs. You answer a few questions about API keys. ~30 minutes.

If your agent doesn't auto-read AGENTS.md, point it at that file first: https://raw.githubusercontent.com/garrytan/gbrain/master/AGENTS.md is the non-Claude agent operating protocol (install, read order, trust boundary, common tasks). For the full doc map, use llms.txt at the same URL root.

Standalone CLI (no agent)

git clone https://github.com/garrytan/gbrain.git && cd gbrain && bun install && bun link
gbrain init                     # local brain, ready in 2 seconds
gbrain import ~/notes/          # index your markdown
gbrain query "what themes show up across my notes?"

Do NOT use bun install -g github:garrytan/gbrain. Bun blocks the top-level postinstall hook on global installs, so schema migrations never run and the CLI aborts with Aborted() the first time it opens PGLite. Use git clone + bun install && bun link as shown above. See #218.

The 26 Skills

GBrain ships 26 skills organized by skills/RESOLVER.md. The resolver tells your agent which skill to read for any task.

Skill files are code. They're the most powerful way to get knowledge work done. A skill file is a fat markdown document that encodes an entire workflow: when to fire, what to check, how to chain with other skills, what quality bar to enforce. The agent reads the skill and executes it. Skills can also call deterministic TypeScript code bundled in GBrain (search, import, embed, sync) for the parts that shouldn't be left to LLM judgment. Thin harness, fat skills: the intelligence lives in the skills, not the runtime.

Always-on

Skill	What it does
signal-detector	Fires on every message. Spawns a cheap model in parallel to capture original thinking and entity mentions. The brain compounds on autopilot.
brain-ops	Brain-first lookup before any external API. The read-enrich-write loop that makes every response smarter.

Content ingestion

Skill	What it does
ingest	Thin router. Detects input type and delegates to the right ingestion skill.
idea-ingest	Links, articles, tweets become brain pages with analysis, author people pages, and cross-linking.
media-ingest	Video, audio, PDF, books, screenshots, GitHub repos. Transcripts, entity extraction, backlink propagation.
meeting-ingestion	Transcripts become brain pages. Every attendee gets enriched. Every company gets a timeline entry.

Brain operations

Skill	What it does
enrich	Tiered enrichment (Tier 1/2/3). Creates and updates person/company pages with compiled truth and timelines.
query	3-layer search with synthesis and citations. Says "the brain doesn't have info on X" instead of hallucinating.
maintain	Periodic health: stale pages, orphans, dead links, citation audit, back-link enforcement, tag consistency.
citation-fixer	Scans pages for missing or malformed citations. Fixes format to match the standard.
repo-architecture	Where new brain files go. Decision protocol: primary subject determines directory, not format.
publish	Share brain pages as password-protected HTML. Zero LLM calls.
data-research	Structured data research with parameterized YAML recipes. Extract investor updates, expenses, company metrics from email.

Operational

Skill	What it does
daily-task-manager	Task lifecycle with priority levels (P0-P3). Stored as searchable brain pages.
daily-task-prep	Morning prep: calendar lookahead with brain context per attendee, open threads, task review.
cron-scheduler	Schedule staggering (5-min offsets), quiet hours (timezone-aware with wake-up override), idempotency.
reports	Timestamped reports with keyword routing. "What's the latest briefing?" finds it instantly.
cross-modal-review	Quality gate via second model. Refusal routing: if one model refuses, silently switch.
webhook-transforms	External events (SMS, meetings, social mentions) converted into brain pages with entity extraction.
testing	Validates every skill has SKILL.md with frontmatter, manifest coverage, resolver coverage.
skill-creator	Create new skills following the conformance standard. MECE check against existing skills.
minion-orchestrator	Long-running agent work as background jobs. Submit, fan out children with depth/cap/timeouts, collect results via child_done inbox.

Identity and setup

Skill	What it does
soul-audit	6-phase interview generating SOUL.md (agent identity), USER.md (user profile), ACCESS_POLICY.md (4-tier privacy), HEARTBEAT.md (operational cadence).
setup	Auto-provision PGLite or Supabase. First import. GStack detection.
migrate	Universal migration from Obsidian, Notion, Logseq, markdown, CSV, JSON, Roam.
briefing	Daily briefing with meeting context, active deals, and citation tracking.

Conventions

Cross-cutting rules in skills/conventions/:

• quality.md ... citations, back-links, notability gate, source attribution
• brain-first.md ... 5-step lookup before any external API call
• model-routing.md ... which model for which task
• test-before-bulk.md ... test 3-5 items before any batch operation
• cross-modal.yaml ... review pairs and refusal routing chain

How It Works

Signal arrives (meeting, email, tweet, link)
  -> Signal detector captures ideas + entities (parallel, never blocks)
  -> Brain-ops: check the brain first (gbrain search, gbrain get)
  -> Respond with full context
  -> Write: update brain pages with new information + citations
  -> Auto-link: typed relationships extracted on every write (zero LLM calls)
  -> Sync: gbrain indexes changes for next query

Every cycle adds knowledge. The agent enriches a person page after a meeting. Next time that person comes up, the agent already has context. The difference compounds daily.

The system gets smarter on its own. Entity enrichment auto-escalates: a person mentioned once gets a stub page (Tier 3). After 3 mentions across different sources, they get web + social enrichment (Tier 2). After a meeting or 8+ mentions, full pipeline (Tier 1). The brain learns who matters without being told. Deterministic classifiers improve over time via a fail-improve loop that logs every LLM fallback and generates better regex patterns from the failures. gbrain doctor shows the trajectory: "intent classifier: 87% deterministic, up from 40% in week 1."

"Prep me for my meeting with Jordan in 30 minutes" ... pulls dossier, shared history, recent activity, open threads

"What have I said about the relationship between shame and founder performance?" ... searches YOUR thinking, not the internet

Minions: your sub-agents won't drop work anymore

A durable, Postgres-native job queue built into the brain. Every long-running agent task is now a job that survives gateway restarts, streams progress, gets paused / resumed / steered mid-flight, and shows up in gbrain jobs list. Zero infra beyond your existing brain.

The production numbers that matter

Here's my personal OpenClaw deployment: one Render container. Supabase Postgres holding a 45,000-page brain. 19 cron jobs firing on schedule. Real gateway load from real daily work. The task: pull a month of my social posts from an external API and ingest them end-to-end into the brain as a structured page.

	Minions	sessions_spawn
Wall time	753ms	>10,000ms (gateway timeout)
Token cost	$0.00	~$0.03 per run
Success rate	100%	0% (couldn't even spawn)
Memory/job	~2 MB	~80 MB

Under that 19-cron load, sub-agent spawn couldn't clear the 10-second gateway wall. Minions landed it in under a second for zero tokens. Scaling: 19,240 posts across 36 months, single bash loop, ~15 min total, $0.00. Sub-agents: ~9 min best case, ~$1.08 in tokens, ~40% spawn failure. Lab: durability ∞ (SIGKILL mid-flight, 10/10 rescued), throughput ~10× faster, fan-out ~21× with no failure wall, memory ~400× less.

Full benchmarks: production and lab.

The routing rule

Deterministic (same input → same steps → same output) → Minions Judgment (input requires assessment or decision) → Sub-agents

Pull posts, parse JSON, write a brain page, run a sync — deterministic. $0 tokens, survives restart, millisecond runtime. Triage the inbox, assess meeting priority, decide if a cold email deserves a reply — judgment. What sub-agents are actually good at. minion_mode: pain_triggered (the default) automates the routing.

What's fixed

The six daily pains — spawn storms, agents that stop responding, forgotten dispatches, gateway crashes mid-run, runaway grandchildren, debugging soup — all belonged to the "deterministic work through a reasoning model" mistake. Minions fixes them by not making that mistake: max_children cap, timeout_ms + AbortSignal, child_done inbox, full parent_job_id/depth/transcript per job, Postgres durability with stall detection, cascade cancel via recursive CTE. Plus idempotency keys, attachment validation, removeOnComplete, and gbrain jobs smoke that proves the install in half a second.

gbrain jobs smoke                        # verify install
gbrain jobs submit sync --params '{}'    # fire a background job
gbrain jobs stats                        # health dashboard
gbrain jobs work --concurrency 4         # start a worker (Postgres only)

Read skills/minion-orchestrator/SKILL.md for parent-child DAGs, fan-in collection, steering via inbox.

Minions is not incrementally better than sub-agents for background work. It's categorically different. 753ms vs gateway timeout. $0 vs tokens. 100% vs couldn't-spawn. If your agent does deterministic work on a schedule, it runs on Minions now.

Health check and self-heal

Minions is canonical as of v0.11.1 — every gbrain upgrade runs the migration automatically (schema → smoke → prefs → host rewrites → env-aware autopilot install). If you ever want to verify manually or wire a cron into your morning briefing:

gbrain doctor                    # half-migrated state? prints loud banner + exits non-zero
gbrain skillpack-check --quiet    # exit 0/1/2 for pipeline gating
gbrain skillpack-check | jq       # full JSON: {healthy, summary, actions[], doctor, migrations}

If anything's off, actions[] tells you the exact command to run. For deeper troubleshooting: docs/guides/minions-fix.md.

Skillify: your skills tree stops being a black box

Hermes and similar agent frameworks auto-create skills as a background behavior. Fine until you don't know what the agent shipped. Checklists decay. Tests drift. Resolver entries get stale. Six months later you've got an opaque pile of "skills" that nobody has read, nobody has tested, and nobody is sure still work.

GBrain ships the same capability. Except the human stays in the loop.

• /skillify turns raw code into a properly-skilled feature: SKILL.md + deterministic script + unit tests + integration tests + LLM evals + resolver trigger + resolver trigger eval + E2E smoke + brain filing. Ten items. Every one required.
• gbrain check-resolvable walks the whole skills tree: reachability, MECE overlap, DRY violations, gap detection, orphaned skills. Exits non-zero if anything is off.
• scripts/skillify-check.ts — machine-readable audit. --json for CI, --recent for last-7-days files.

You decide when and what. The tooling keeps the checklist honest.

Why this is the right answer for OpenClaw

Auto-generated skills are a liability the first time a behavior breaks. Was it the skill? The test? The resolver trigger? The eval? You don't know, because you never read it. Debugging a black box is pure guesswork.

Skillify makes the black box legible. Every skill in your tree has: a contract (SKILL.md), tests that exercise that contract, an eval that grades LLM output against a rubric, a resolver trigger the user actually types, and a test that confirms the trigger routes right. If something breaks, you know which layer to look at. If anything goes stale, check-resolvable says so.

In practice this combo produces zero orphaned skills, every feature with tests + evals + resolver triggers + evals of the triggers. Compounding quality instead of compounding entropy.

# Audit a feature's skill completeness (10-item checklist)
bun run scripts/skillify-check.ts src/commands/publish.ts

# In CI: fail the build when a new feature isn't properly skilled
bun run scripts/skillify-check.ts --json --recent

# Validate the whole skills tree before shipping
gbrain check-resolvable

Skillify is not a nice-to-have. It's the piece that makes the skills tree survive six months of compounding work. Read skills/skillify/SKILL.md for the full 10-item checklist and the anti-patterns it catches.

Getting Data In

GBrain ships integration recipes that your agent sets up for you. Each recipe tells the agent what credentials to ask for, how to validate, and what cron to register.

Recipe	Requires	What It Does
Public Tunnel	—	Fixed URL for MCP + voice (ngrok Hobby $8/mo)
Credential Gateway	—	Gmail + Calendar access
Voice-to-Brain	ngrok-tunnel	Phone calls to brain pages (Twilio + OpenAI Realtime)
Email-to-Brain	credential-gateway	Gmail to entity pages
X-to-Brain	—	Twitter timeline + mentions + deletions
Calendar-to-Brain	credential-gateway	Google Calendar to searchable daily pages
Meeting Sync	—	Circleback transcripts to brain pages with attendees

Data research recipes extract structured data from email into tracked brain pages. Built-in recipes for investor updates (MRR, ARR, runway, headcount), expense tracking, and company metrics. Create your own with gbrain research init.

Run gbrain integrations to see status.

GBrain + GStack

GStack is the engine. GBrain is the mod.

• GStack = coding skills (ship, review, QA, investigate, office-hours, retro). 70,000+ stars, 30,000 developers per day. When your agent codes on itself, it uses GStack.
• GBrain = everything-else skills (brain ops, signal detection, ingestion, enrichment, cron, reports, identity). When your agent remembers, thinks, and operates, it uses GBrain.
• hosts/gbrain.ts = the bridge. Tells GStack's coding skills to check the brain before coding.

gbrain init detects if GStack is installed and reports mod status. If GStack isn't there, it tells you how to get it.

The repo is the system of record. GBrain is the retrieval layer. The agent reads and writes through both. Human always wins... edit any markdown file and gbrain sync picks up the changes.

The Knowledge Model

Every page follows the compiled truth + timeline pattern:

---
type: concept
title: Do Things That Don't Scale
tags: [startups, growth, pg-essay]
---

Paul Graham's argument that startups should do unscalable things early on.
The key insight: the unscalable effort teaches you what users actually
want, which you can't learn any other way.

- 2024-11-15: Referenced in batch W25 kickoff talk

Above the ---: compiled truth. Your current best understanding. Gets rewritten when new evidence changes the picture. Below: timeline. Append-only evidence trail. Never edited, only added to.

Knowledge Graph

Pages aren't just text. Every mention of a person, company, or concept becomes a typed link in a structured graph. The brain wires itself.

Write a meeting page mentioning Alice and Acme AI
  -> Auto-link extracts entity refs from content (zero LLM calls)
  -> Infers types: meeting page + person ref => `attended`
                   "CEO of X" pattern        => `works_at`
                   "invested in"             => `invested_in`
                   "advises", "advisor"      => `advises`
                   "founded", "co-founded"   => `founded`
  -> Reconciles stale links: edits remove links no longer in content
  -> Backlinks rank well-connected entities higher in search

gbrain graph-query people/alice --type attended --depth 2
# returns who Alice met with, transitively

The graph powers questions vector search can't: "who works at Acme AI?", "what has Bob invested in?", "find the connection between Alice and Carol". Backfill an existing brain in one command:

gbrain extract links --source db        # wire up the existing 29K pages
gbrain extract timeline --source db     # extract dated events from markdown timelines

Then ask graph questions or watch the search ranking improve. Benchmarked: Recall@5 jumps from 83% to 95%, Precision@5 from 39% to 45%, +30 more correct answers in the agent's top-5 reads on a 240-page Opus-generated rich-prose corpus. Graph-only F1 hits 86.6% vs grep's 57.8% (+28.8 pts). See docs/benchmarks/2026-04-18-brainbench-v1.md.

Search

Hybrid search: vector + keyword + RRF fusion + multi-query expansion + 4-layer dedup.

Query
  -> Intent classifier (entity? temporal? event? general?)
  -> Multi-query expansion (Claude Haiku)
  -> Vector search (HNSW cosine) + Keyword search (tsvector)
  -> RRF fusion: score = sum(1/(60 + rank))
  -> Cosine re-scoring + compiled truth boost
  -> 4-layer dedup + compiled truth guarantee
  -> Results

Keyword alone misses conceptual matches. Vector alone misses exact phrases. RRF gets both. Search quality is benchmarked and reproducible: gbrain eval --qrels queries.json measures P@k, Recall@k, MRR, and nDCG@k. A/B test config changes before deploying them.

Why it works: many strategies in concert

The brain isn't one trick. Every retrieval question goes through ~20 deterministic techniques layered together. No single one is magic; the win comes from stacking them so each layer covers what the others miss.

Question
  │
  ├─ INGESTION (every put_page)
  │    ├─ Recursive markdown chunking (or semantic / LLM-guided)
  │    ├─ Embedding cache invalidation on edit
  │    └─ Idempotent imports (content-hash dedup)
  │
  ├─ GRAPH EXTRACTION (auto-link post-hook, zero LLM)
  │    ├─ Entity-ref regex (markdown links + bare slugs)
  │    ├─ Code-fence stripping (no false-positive slugs in code blocks)
  │    ├─ Typed inference cascade (FOUNDED → INVESTED → ADVISES → WORKS_AT)
  │    ├─ Page-role priors (partner-bio language → invested_in)
  │    ├─ Within-page dedup (same target collapses to one link)
  │    ├─ Stale-link reconciliation (edits remove dropped refs)
  │    └─ Multi-type link constraint (same person can works_at AND advises)
  │
  ├─ SEARCH PIPELINE (every query)
  │    ├─ Intent classifier (entity / temporal / event / general — auto-routes)
  │    ├─ Multi-query expansion (Haiku rephrases the question 3 ways)
  │    ├─ Vector search (HNSW cosine over OpenAI embeddings)
  │    ├─ Keyword search (Postgres tsvector + websearch_to_tsquery)
  │    ├─ Reciprocal Rank Fusion (score = sum 1/(60+rank) across both)
  │    ├─ Cosine re-scoring (re-rank chunks against actual query embedding)
  │    ├─ Compiled-truth boost (assessments outrank timeline noise)
  │    ├─ Backlink boost (well-connected entities rank higher)
  │    └─ Source-aware dedup (one CT chunk per page guaranteed)
  │
  ├─ GRAPH TRAVERSAL (relational queries)
  │    ├─ Recursive CTE with cycle prevention (visited-array check)
  │    ├─ Type-filtered edges (--type works_at, attended, etc.)
  │    ├─ Direction control (in / out / both)
  │    └─ Depth-capped (≤10 for remote MCP; DoS prevention)
  │
  └─ AGENT WORKFLOW (graph-confident hybrid)
       ├─ Graph-query first (high-precision typed answers)
       ├─ Grep fallback when graph returns nothing
       └─ Graph hits ranked first in top-K (better P@K and R@K)

End-to-end on the BrainBench v1 corpus (240 rich-prose pages, before/after PR #188):

Metric	BEFORE PR #188	AFTER PR #188	Δ
Precision@5	39.2%	44.7%	+5.4 pts
Recall@5	83.1%	94.6%	+11.5 pts
Correct in top-5	217	247	+30
Graph-only F1 (ablation)	57.8% (grep)	86.6%	+28.8 pts

Plus 5 orthogonal capability checks (identity resolution, temporal queries, performance at 10K-page scale, robustness to malformed input, MCP operation contract). All pass. Full report.

The point: each technique handles a class of inputs the others miss. Vector search misses exact slug refs; keyword catches them. Keyword misses conceptual matches; vector catches them. RRF picks the best of both. Compiled-truth boost keeps assessments above timeline noise. Auto-link extraction wires the graph that lets backlink boost rank well-connected entities higher. Graph traversal answers questions search alone can't reach. The agent picks graph-first for precision and falls back to keyword for recall. All deterministic, all in concert, all measured.

Voice

Call a phone number. Your AI answers. It knows who's calling, pulls their full context from the brain, and responds like someone who actually knows your world. When the call ends, a brain page appears with the transcript, entity detection, and cross-references.

See it in action

The voice recipe ships with GBrain: Voice-to-Brain. WebRTC works in a browser tab with zero setup. A real phone number is optional.

PGLite: embedded Postgres, no server, zero config. When your brain outgrows local (1000+ files, multi-device), gbrain migrate --to supabase moves everything.

File Storage

Brain repos accumulate binaries. GBrain has a three-stage migration:

gbrain files mirror <dir>       # copy to cloud, local untouched
gbrain files redirect <dir>     # replace local with .redirect pointers
gbrain files clean <dir>        # remove pointers, cloud only
gbrain files restore <dir>      # download everything back (undo)

Storage backends: S3-compatible (AWS, R2, MinIO), Supabase Storage, or local.

Origin Story

I was setting up my OpenClaw agent and started a markdown brain repo. One page per person, one page per company, compiled truth on top, timeline on the bottom. Within a week: 10,000+ files, 3,000+ people, 13 years of calendar data, 280+ meeting transcripts, 300+ captured ideas.

The agent runs while I sleep. The dream cycle scans every conversation, enriches missing entities, fixes broken citations, consolidates memory. I wake up and the brain is smarter than when I went to sleep.

The skills in this repo are those patterns, generalized. What took 11 days to build by hand ships as a mod you install in 30 minutes.
