Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00038 | $0.01585 |
| Opus 5 | $0.00019 | $0.00792 |
| Sonnet 5 | $0.00008 | $0.00317 |
| Haiku 4.5 | $0.00004 | $0.00159 |
Grade A, and why
gbrain-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GBrain CLI
Overview
GBrain is a local CLI plus a local SQLite database, not a hosted web service.
The stable mental model is:
- binary:
gbrain - data file:
brain.db - MCP entrypoint:
gbrain serve --db /absolute/path/to/brain.db
If someone says "deploy GBrain", translate that into one of three jobs:
- install the binary locally
- initialize or use a local
brain.db - connect an MCP client to
gbrain serve
Primary repo docs:
When to Use
Use this skill when someone asks how to:
- install
gbrain - deploy it locally
- initialize a new brain
- configure OpenAI or OpenRouter embeddings
- connect GBrain to Claude Code, Codex, or OpenClaw
- upgrade the installed binary
- troubleshoot local CLI or MCP setup
Do not use this skill for schema design, search ranking, or migration debugging inside the repo. That is code work, not operator guidance.
Quick Start
From source:
git clone https://github.com/laozhong86/gbrain.git
cd gbrain
bun install
bun run check
bun test
bun run build
Install the binary into PATH:
mkdir -p ~/.local/bin
cp bin/gbrain ~/.local/bin/gbrain
chmod +x ~/.local/bin/gbrain
Recommended local data path:
mkdir -p ~/.gbrain
gbrain init ~/.gbrain/main.db
gbrain stats --db ~/.gbrain/main.db
OpenClaw-specific preset:
export GBRAIN_PROFILE=openclaw
gbrain init
gbrain stats
That preset resolves the default database path to ~/.openclaw/brain.db while keeping the generic CLI behavior unchanged for everyone else.
Minimum smoke checks:
gbrain version
gbrain --tools-json
gbrain stats --db ~/.gbrain/main.db
Embeddings
Lexical search works without any model key:
gbrain search "Jensen Huang" --db ~/.gbrain/main.db
Embeddings and hybrid query require a provider key.
OpenAI:
export OPENAI_API_KEY=your_key
OpenRouter:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gbrain-cli is a skill published in the GitHub repository laozhong86/gbrain (8 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 1,585 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
