ShellBrain

Long-term Memory for AI Agents.

ShellBrain gives AI agents memory, so they can store and reuse what they learn over time.

Install

curl -L shellbrain.ai/install | bash

Works for Codex, Claude Code, and Cursor. The installer runs shellbrain init for you. Repos register themselves on first use.

Requirements.

  • macOS or Linux, Python 3.11+, Docker for the managed local Postgres+pgvector runtime.

Upgrade for latest capabilities

shellbrain upgrade

You can also run curl -L shellbrain.ai/upgrade | bash. Manual alternative: pipx upgrade shellbrain && shellbrain init.

Recall in one command

ShellBrain recall uses vector search and BM25 to search your memories. An inner recall agent summarizes the search results.

Architecture

ShellBrain builds memory in three grounded layers:

  • Episodic knowledge records evidence. It stores prompts, agent steps, tool calls, and outputs from each session.
  • Empirical knowledge extracts concrete memories. It organizes problems, solutions, failed tactics, facts, preferences, and changes in a semantic graph for case-based reasoning.
  • Conceptual knowledge abstracts reusable ideas. Its concept graph connects claims, relations, and implementations to empirical knowledge.

Each higher layer links to evidence in the layer below it. Agents receive a compact orientation first, then request more detail when needed.

How Agents Use ShellBrain

Recall

Working agents run shellbrain recall to get one compact brief for the current task.

Recall receives only the quoted query. Include the relevant task, failure, subsystem, or decision in the question.

shellbrain recall "What is ShellBrain, and how does it help a working coding agent?"

Response format:

{
  "status": "ok",
  "data": {
    "brief": {
      "summary": "...",
      "constraints": ["..."],
      "known_traps": ["..."],
      "prior_cases": ["..."],
      "concept_orientation": ["..."],
      "anchors": ["`README.md`"],
      "conflicts": ["..."],
      "gaps": ["..."],
      "next_checks": ["..."]
    },
    "fallback_reason": null
  },
  "errors": []
}

The brief lets the working agent focus on the current task.

Teach

Run shellbrain teach only when you explicitly want ShellBrain to remember something important.

Memory Discipline

ShellBrain keeps memory grounded in evidence and narrow in scope. Agents request memory when they need it.

Memory that cannot justify itself should not persist.

Use ShellBrain

Use Shellbrain with your preferred agent. Then work as usual.

  • Claude Code: Use /shellbrain to recall context at task boundaries.
  • Codex: Use $shellbrain to recall context at task boundaries.
  • Cursor: Use /shellbrain to recall context at task boundaries.

Repair

Run shellbrain admin doctor to inspect the installation. If it reports a problem, run shellbrain init. Do not run init every session.
