Usage

Installation

Run the one-click installer:

# Windows
install.bat

# Linux/macOS
chmod +x install.sh && ./install.sh

Configuration

Update config.yaml:

vector_store:
  type: chromadb
  path: "./chromadb"
  model: "BAAI/bge-m3"

Migration

Run the migration script to import existing LanceDB data:

python migrate_lancedb.py --lancedb-path ./lancedb --chromadb-path ./chromadb

Commands

  • test_chromadb.py: Verify plugin installation and functionality
  • migrate_lancedb.py: Migrate existing LanceDB data to ChromaDB

Dependencies

  • chromadb >= 0.4.0
  • sentence-transformers >= 2.2.0
  • pyyaml >= 6.0
Usage Guidance
This package appears to be what it claims: a ChromaDB integration and LanceDB migration tool. Before installing: 1) Review install.sh (it runs pip3 install and copies files to ~/.openclaw) and consider running it inside a virtualenv or container to avoid altering your system Python. 2) Backup your existing LanceDB data before running migration scripts. 3) If you plan to use a cloud ChromaDB endpoint, only provide an API key where absolutely necessary and verify the endpoint URL. 4) Note minor mismatches (SKILL.md shows EvoChroma 2.0.0 while registry lists v1.0.1 and source/homepage are not from a well-known vendor) — if provenance matters, ask the publisher for a canonical source or signed release. 5) Run test_chromadb.py in an isolated environment first to confirm behavior. Overall, no unexplained credentials or hidden network endpoints were found, but standard caution with third-party Python packages and installers applies.
Capability Analysis
Type: OpenClaw Skill Name: chromadb-plugin Version: v1.0.1 The bundle provides a legitimate ChromaDB vector store integration for OpenClaw, including installation scripts (install.sh), migration tools (migrate_lancedb.py), and extensive documentation. While the code in chromadb_plugin.py contains hardcoded 'watermark' strings and a specific logic branch to return author metadata upon a specific query ('LANLAN_ORIGIN_CHECK'), these are explicitly documented as attribution mechanisms and do not perform harmful actions. No evidence of data exfiltration, malicious execution, or unauthorized persistence was found.
Capability Assessment
✓ Purpose & Capability
Name/description (ChromaDB integration, migration from LanceDB, GPU acceleration) match the included Python code, migration script, tests, and installer. Optional cloud parameters (host/port/api_key) in code and docs are appropriate for supporting an on-prem vs cloud ChromaDB deployment.
✓ Instruction Scope
SKILL.md and scripts instruct only to install Python deps, copy plugin files to ~/.openclaw, update config.yaml, and run migration/tests. The migration script intentionally reads from a provided LanceDB path and the user's OpenClaw installation path (~/.openclaw); these actions are coherent with the migration purpose but will touch user OpenClaw files and should be run with care.
ℹ Install Mechanism
No registry install spec was declared, but an executable install.sh is included and recommended by SKILL.md. install.sh runs pip3 install chromadb sentence-transformers pyyaml (normal for this plugin) and copies files into ~/.openclaw/extensions/chromadb and creates a config under ~/.openclaw/config. Using pip from the network is reasonable here but carries the usual supply-chain/network risk; running the installer in a virtualenv/container reduces exposure.
✓ Credentials
The plugin declares no required environment variables in metadata and none are required at runtime; docs mention optional CHROMADB_* env vars and the code accepts an optional api_key for cloud-hosted ChromaDB. Requesting an API key only when connecting to a cloud endpoint is proportionate.
ℹ Persistence & Privilege
always:false and no elevated flags. The installer persists files under the user's home (~/.openclaw) and performs global pip installs (pip3), which is normal for a plugin but does modify the user's Python environment and OpenClaw extension directory. This is expected for an extension but worth noting to users who prefer isolated installs.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install chromadb-plugin
  3. After installation, invoke the skill by name or use /chromadb-plugin
  4. Provide required inputs per the skill's parameter spec and get structured output
