Description
Browse the web via Plasmate, a fast headless browser engine for agents. Compiles HTML into a Semantic Object Model (SOM) - 50x faster than Chrome, 10x fewer...
Usage Guidance
This skill appears to do what it says: control a local Plasmate headless browser. Before installing, consider: 1) Prefer building from source (cargo install) if you need stronger assurance; 2) If you use the 'curl | sh' installer, review the install script at https://plasmate.app/install.sh to ensure it does what you expect; 3) The provided Python helper will pip-install the 'websockets' package if missing — that modifies your Python environment and reaches out to PyPI; run it in a virtualenv or sandbox if you want to avoid global changes; 4) The Plasmate server listens on localhost (9222 by default) — if you run other local tools that connect to that port, be aware they could interact with the same server; 5) Verify the upstream project (GitHub/source) and the integrity of downloaded binaries if you require higher assurance.
Capability Analysis
Type: OpenClaw Skill
Name: plasmate
Version: 3.2.0
The Plasmate skill provides a headless browser engine optimized for AI agents, using a Semantic Object Model (SOM) for efficiency. The bundle includes a Python client (scripts/awp-browse.py) that communicates with a local Plasmate server via WebSockets and handles basic browser actions like navigation and element interaction. While the installation instructions include a 'curl | sh' method and the script automatically installs the 'websockets' library via pip, these behaviors are standard for developer tools of this nature and align with the stated purpose without evidence of malicious intent or data exfiltration.
Capability Assessment
Purpose & Capability
Name/description, required binary (plasmate), install options, and the included Python AWP client all align: the skill exists to control a local Plasmate server. There are no unexpected credentials, unrelated binaries, or external services required.
Instruction Scope
SKILL.md and scripts limit actions to starting/connecting to a local Plasmate server and issuing AWP/CDP commands. They do not attempt to read unrelated system files or exfiltrate data. One scope mismatch: the Python client auto-installs the 'websockets' pip package at runtime if missing; this side-effect is not documented in SKILL.md metadata and will modify the environment.
Install Mechanism
Two install options are provided: 'cargo install plasmate' (build from source) and 'curl -fsSL https://plasmate.app/install.sh | sh' (run remote installer). The remote-install pattern (pipe-to-sh) is convenient but inherently risky — it executes a script fetched from the network. The domain is the project's official site (plasmate.app), which reduces suspicion, and a source/build option is available, lowering risk further.
Credentials
The skill does not request credentials, environment variables, or config paths. The only noteworthy environment access is starting a local server on a standard localhost port and the helper script's ability to pip-install a dependency (network access to PyPI). Those are proportionate to running a local headless browser client.
Persistence & Privilege
The skill is not always-enabled and does not request elevated platform privileges. It may start a local 'plasmate serve' process (expected behavior) but does not modify other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install plasmate - After installation, invoke the skill by name or use
/plasmate - Provide required inputs per the skill's parameter spec and get structured output
