ShellBrain
Long-term Memory for AI.
ShellBrain uses case-based reasoning and a self-managing concept graph as long-term memory for software engineering.
Install
curl -L shellbrain.ai/install | bash
Works for Codex, Claude Code, and Cursor.
Requirements.
- macOS or Linux, Python 3.11+, Docker.
Upgrade for Latest Capabilities
shellbrain upgrade
Recall in One Command
Architecture
ShellBrain stores evidence and two forms of reusable knowledge:
- Episodic Memory. It stores prompts, responses, and tool calls.
- Case-Based Memory. Problems, solutions, and failed attempts are structured and stored.
- Concept Graph. It connects claims, relations, and implementations.
Memories and concepts link directly to supporting evidence. The code is the source of truth.
How Agents Use ShellBrain
Recall
Working agents run shellbrain recall for long-term memory related to their current task.
Recall combines BM25, vector similarity, and explicit graph associations.
shellbrain recall "What is ShellBrain, and how does it help a working coding agent?"
Response:
{
"status": "ok",
"data": {
"brief": {
"summary": "...",
"constraints": ["..."],
"known_traps": ["..."],
"prior_cases": ["..."],
"concept_orientation": ["..."],
"anchors": ["`README.md`"],
"conflicts": ["..."],
"gaps": ["..."],
"next_checks": ["..."]
},
"fallback_reason": null
},
"errors": []
}
If there are no relevant memories, nothing is returned.
Recall Provider
For blazing fast recall for cheap, get an Inception API key and run:
mkdir -p ~/.shellbrain
printf '\nINCEPTION_API_KEY=%s\n' 'PASTE_YOUR_KEY_HERE' >> ~/.shellbrain/.env
chmod 600 ~/.shellbrain/.env
shellbrain admin recall provider inception
Switch back with shellbrain admin recall provider codex, or choose claude.
Tune recall in ~/.shellbrain/recall.yaml (optional; these are the defaults):
recall:
max_memories: 12
max_concepts: 4
max_neighbor_concepts: 2
max_claims_per_concept: 3
max_groundings_per_concept: 2
max_input_tokens: 8000
The input budget uses a byte-based token estimate. Settings affect recall synthesis only.
