Jasper Recall v0.2.3

Local RAG (Retrieval-Augmented Generation) system for AI agent memory. Gives your agent the ability to remember and search past conversations.

New in v0.2.2: Shared ChromaDB Collections — separate collections for private, shared, and learnings content. Better isolation for multi-agent setups.

New in v0.2.1: Recall Server — HTTP API for Docker-isolated agents that can't run CLI directly.

New in v0.2.0: Shared Agent Memory — bidirectional learning between main and sandboxed agents with privacy controls.

When to Use

Memory recall: Search past sessions for context before answering
Continuous learning: Index daily notes and decisions for future reference
Session continuity: Remember what happened across restarts
Knowledge base: Build searchable documentation from your agent's experience

Quick Start

Setup

One command installs everything:

npx jasper-recall setup

This creates:

Python venv at ~/.openclaw/rag-env
ChromaDB database at ~/.openclaw/chroma-db
CLI scripts in ~/.local/bin/
OpenClaw plugin config in openclaw.json

Why Python?

The core search and embedding functionality uses Python libraries:

ChromaDB — Vector database for semantic search
sentence-transformers — Local embedding models (no API needed)

These are the gold standard for local RAG. There are no good Node.js equivalents that work fully offline.

Why a Separate Venv?

The venv at ~/.openclaw/rag-env provides:

Benefit	Why It Matters
Isolation	Won't conflict with your other Python projects
No sudo	Installs to your home directory, no root needed
Clean uninstall	Delete the folder and it's gone
Reproducibility	Same versions everywhere

The dependencies are heavy (~200MB total with the embedding model), but this is a one-time download that runs entirely locally.

Basic Usage

Search your memory:

recall "what did we decide about the API design"
recall "hopeIDS patterns" --limit 10
recall "meeting notes" --json

Index your files:

index-digests  # Index memory files into ChromaDB

Create session digests:

digest-sessions          # Process new sessions
digest-sessions --dry-run  # Preview what would be processed

How It Works

Three Components

digest-sessions — Extracts key info from session logs (topics, tools used)
index-digests — Chunks and embeds markdown files into ChromaDB
recall — Semantic search across your indexed memory

What Gets Indexed

By default, indexes files from ~/.openclaw/workspace/memory/:

*.md — Daily notes, MEMORY.md
session-digests/*.md — Session summaries
repos/*.md — Project documentation
founder-logs/*.md — Development logs (if present)

Embedding Model

Uses sentence-transformers/all-MiniLM-L6-v2:

384-dimensional embeddings
~80MB download on first run
Runs locally, no API needed

Agent Integration

Memory-Augmented Responses

# Before answering questions about past work
results = exec("recall 'project setup decisions' --json")
# Include relevant context in your response

Automated Indexing (Heartbeat)

Add to HEARTBEAT.md:

## Memory Maintenance
- [ ] New session logs? → `digest-sessions`
- [ ] Memory files updated? → `index-digests`

Cron Job

Schedule regular indexing:

{
  "schedule": { "kind": "cron", "expr": "0 */6 * * *" },
  "payload": {
    "kind": "agentTurn",
    "message": "Run index-digests to update the memory index"
  },
  "sessionTarget": "isolated"
}

Shared Agent Memory (v0.2.0+)

For multi-agent setups where sandboxed agents need access to some memories:

Memory Tagging

Tag entries in daily notes:

## 2026-02-05 [public] - Feature shipped
This is visible to all agents.

## 2026-02-05 [private] - Personal note
This is main agent only (default if untagged).

## 2026-02-05 [learning] - Pattern discovered
Learnings shared bidirectionally between agents.

ChromaDB Collections (v0.2.2+)

Memory is stored in separate collections for isolation:

Collection	Purpose	Who accesses
`private_memories`	Main agent's private content	Main agent only
`shared_memories`	[public] tagged content	Sandboxed agents
`agent_learnings`	Learnings from any agent	All agents
`jasper_memory`	Legacy unified (backward compat)	Fallback

Collection selection:

# Main agent (default) - searches private_memories
recall "api design"

# Sandboxed agents - searches shared_memories only
recall "product info" --public-only

# Search learnings only
recall "patterns" --learnings

# Search all collections (merged results)
recall "everything" --all

# Specific collection
recall "something" --collection private_memories

# Legacy mode (single collection)
recall "old way" --legacy

Sandboxed Agent Access

# Sandboxed agents use --public-only
recall "product info" --public-only

# Main agent can see everything
recall "product info"

Moltbook Agent Setup (v0.4.0+)

For the moltbook-scanner (or any sandboxed agent), use the built-in setup:

# Configure sandboxed agent with --public-only restriction
npx jasper-recall moltbook-setup

# Verify the setup is correct
npx jasper-recall moltbook-verify

This creates:

~/bin/recall — Wrapper that forces --public-only flag
shared/ — Symlink to main workspace's shared memory

The sandboxed agent can then use:

~/bin/recall "query"  # Automatically restricted to public memories

Privacy model:

Main agent tags memories as [public] or [private] in daily notes
sync-shared extracts [public] content to memory/shared/
Sandboxed agents can ONLY search the shared collection

Privacy Workflow

# Check for sensitive data before sharing
privacy-check "text to scan"
privacy-check --file notes.md

# Extract [public] entries to shared directory
sync-shared
sync-shared --dry-run  # Preview first

CLI Reference

recall

recall "query" [OPTIONS]

sync-shared [OPTIONS]

Options:
  --dry-run    Preview without writing
  --all        Process all daily notes

Extracts [public] tagged entries to memory/shared/.

index-digests

index-digests

Indexes markdown files from:
  ~/.openclaw/workspace/memory/*.md
  ~/.openclaw/workspace/memory/session-digests/*.md
  ~/.openclaw/workspace/memory/repos/*.md
  ~/.openclaw/workspace/memory/founder-logs/*.md

Skips files that haven't changed (content hash check).

digest-sessions [OPTIONS]

Options:
  --dry-run    Preview without writing
  --all        Process all sessions (not just new)
  --recent N   Process only N most recent sessions

Configuration

Custom Paths

Set environment variables:

export RECALL_WORKSPACE=~/.openclaw/workspace
export RECALL_CHROMA_DB=~/.openclaw/chroma-db
export RECALL_SESSIONS_DIR=~/.openclaw/agents/main/sessions

Chunking

Default settings in index-digests:

Chunk size: 500 characters
Overlap: 100 characters

Security Considerations

⚠️ Review these settings before enabling in production:

Server Binding

The serve command defaults to 127.0.0.1 (localhost only). Do not use --host 0.0.0.0 unless you explicitly intend to expose the API externally and have secured it appropriately.

Private Memory Access

The server enforces public_only=true by default. The env var RECALL_ALLOW_PRIVATE=true bypasses this restriction. Never set this on public/shared hosts — it exposes your private memories to any client.

autoRecall Plugin

When autoRecall: true in the OpenClaw plugin config, memories are automatically injected before every agent message. Consider:

Set publicOnly: true in plugin config for sandboxed agents
Review which collections will be searched
Use minScore to filter low-relevance injections

What's automatically skipped (no recall triggered):

Heartbeat polls (HEARTBEAT, Read HEARTBEAT.md, HEARTBEAT_OK)
Messages containing NO_REPLY
Messages < 10 characters
Agent-to-agent messages (cron jobs, workers, spawned agents)
Automated reports (📋 PR Review, 🤖 Codex Watch, ANNOUNCE_*)
Messages from senders starting with agent: or worker-

Safer config for untrusted contexts:

"jasper-recall": {
  "enabled": true,
  "config": {
    "autoRecall": true,
    "publicOnly": true,
    "minScore": 0.5
  }
}

Environment Variables

The following env vars affect behavior — set them explicitly rather than relying on defaults:

Variable	Default	Purpose
`RECALL_WORKSPACE`	`~/.openclaw/workspace`	Memory files location
`RECALL_CHROMA_DB`	`~/.openclaw/chroma-db`	Vector database path
`RECALL_SESSIONS_DIR`	`~/.openclaw/agents/main/sessions`	Session logs
`RECALL_ALLOW_PRIVATE`	`false`	Server private access
`RECALL_PORT`	`3458`	Server port
`RECALL_HOST`	`127.0.0.1`	Server bind address

Dry-Run First

Before sharing or syncing, use dry-run options to preview what will be exposed:

privacy-check --file notes.md     # Scan for sensitive data
sync-shared --dry-run             # Preview public extraction
digest-sessions --dry-run         # Preview session processing

Sandboxed Environments

For maximum isolation, run jasper-recall in a container or dedicated account:

Limits risk of accidental data exposure
Separates private memory from shared contexts
Recommended for multi-agent setups with untrusted agents

Troubleshooting

"No index found"

index-digests  # Create the index first

"Collection not found"

rm -rf ~/.openclaw/chroma-db  # Clear and rebuild
index-digests

Model download slow First run downloads ~80MB model. Subsequent runs are instant.
