README

brain-core

A memory for your Claude Code agent that survives the session.

Install in one line

macOS and Linux

curl -fsSL https://raw.githubusercontent.com/xy-claude/brain-core/main/install.sh | bash -s -- --agent Atlas --user Alex --desktop

Windows (PowerShell)

& ([scriptblock]::Create((irm https://raw.githubusercontent.com/xy-claude/brain-core/main/install.ps1))) -Agent Atlas -User Alex -Desktop

Atlas is your agent's name, Alex is yours. When the installer finishes:

cd ~/Agents/Atlas
claude

Both lines install the same things: the agent, Hindsight (the vector store, about 2 GB), the daily and weekly jobs, Claude Code, and the connection to the Claude desktop app. No API key is needed.

You want	macOS and Linux	Windows
The quick install: about a minute, no Hindsight	add `--lite`	add `-Lite`
Claude Code only, not the desktop app	remove `--desktop`	remove `-Desktop`

Every step, every flag and the common problems: Install details.

brain init and brain doctor on a new agent, then a real session: a memory saved with search keys, a changed fact with its banner, a recall in the same words, a recall in other words, and a question that was never saved coming back as a weak match

What you get

Sessions that start where the last one ended. Each one opens with yesterday's brief, your decisions, the facts that changed and the corrections you gave.
Five tools, not thirty. One local MCP server the agent uses by itself.
Files you can read. Memory is markdown in a folder on your disk, indexed by SQLite and, optionally, by Hindsight, a self-hosted vector memory.
Nothing in someone's cloud. Memory stays on your disk. What does go out: the LLM calls Hindsight makes to reason over memories (none with --lite), one version check a day to PyPI, and the pages you ask it to distill.
Search you can check. Every result names its file and date, a weak match is reported as weak, and recall is scored against hand-labelled answers. The numbers, including the ones that are not flattering, are in Does it work?

It is for one person running one or more agents on their own computer. It is not a hosted service and not a team product.

The problem

Every session with a coding agent starts from zero. You explain the project again, the decision you made last week again, the thing it got wrong on Tuesday again. Memory add-ons exist, but they put your notes in someone's cloud, expose 30 tools the agent cannot choose between, and nobody shows you an eval.

brain-core is the opposite: local, five tools, markdown files you own, and an eval with labelled answers whose numbers are published below.

How it works

brain init scaffolds an agent folder. It writes a CLAUDE.md with the agent's name and yours, five rule files (identity, doctrine, authority, memory, system), three skills, four hooks (a safety block, the brief at session start, capture of what you said, recall of past fixes when a command fails), an .mcp.json and an empty vault. Claude Code reads that folder as a project, so the agent knows how to use its memory from the first message.
brain serve runs as an MCP server inside Claude Code. It exposes exactly five tools. The agent calls them the way it calls any other
