emoPAD Universe

Cross-Platform Support

emoPAD Universe supports the following operating systems:

OS Image Viewer Notes
Linux eog (Eye of GNOME) Window mode, closable
Windows System default image viewer Window mode, closable

Auto-Start

After installing this skill, the following operations will be performed automatically:

  1. Check and install required Python dependencies
  2. Start emoPAD service (listening on http://127.0.0.1:8766)
  3. Start emoNebula auto-report (popup window displaying emotion nebula chart every 5 minutes)

No manual start needed, ready to use after installation.

About Emotion PAD Calculation

Important Note: Currently, emotion PAD calculation is based on heuristic methods, mapping relationships summarized from extensive literature.

Characteristics of this method:

  • ✅ Based on statistical patterns from scientific literature
  • ✅ Suitable for emotion recognition in general population
  • ⚠️ Temporarily cannot reflect individual differences

Future Improvements: Will introduce personalized calibration training modules in new versions, through user-specific data training, to achieve true personalized emotion recognition.

Usage Guidance
This skill appears to implement the stated emotion-PAD functionality, but several behaviors are surprising and potentially intrusive: it will auto-install many pip packages, start a background service listening on localhost:8766, and run a periodic process that forcibly sets DISPLAY and XAUTHORITY (hard-coded to /run/user/1000/gdm/Xauthority) and may kill processes (pkill/taskkill). Before installing, consider: 1) Only install if you trust the author and code provenance (there is no homepage). 2) Inspect the code locally (especially the XAUTHORITY/DISPLAY lines and pkill usage). 3) Prefer running inside a confined environment (virtualenv, container, or VM) to avoid affecting other users or the host X session. 4) If you must run on a multi-user desktop, remove or modify the hard-coded XAUTHORITY/DISPLAY behavior and verify that popping windows is acceptable. 5) Be aware pip will download and execute many third-party packages — review required packages and pin versions if possible. If you want, I can point out the exact lines to change to avoid XAUTHORITY/DISPLAY overrides and to make auto-start optional.
Capability Analysis
Type: OpenClaw Skill Name: emopad-universe Version: 0.1.0 The skill bundle implements a multi-modal emotion tracking system (EEG/PPG/GSR) but contains several high-risk patterns. Specifically, `emopad_cli.py` uses `os.system` to execute `xdg-open` on a path constructed from environment variables, which is vulnerable to shell injection. The `install.py` and `nebula.py` scripts perform aggressive automated actions, such as force-installing Python packages and hardcoding X11 authentication paths (`/run/user/1000/gdm/Xauthority`), which could lead to permission issues or unauthorized display access. While these behaviors align with the stated goal of a 'continuous monitoring' service, the lack of input sanitization and the intrusive auto-start mechanism warrant a suspicious classification.
Capability Assessment
ℹ Purpose & Capability
Name/description align with included code: service to compute PAD from EEG/PPG/GSR and a periodic 'emoNebula' poster. Required hardware access (BLE, serial) and Python signal-processing packages match the stated functionality.
⚠ Instruction Scope
SKILL.md and install scripts instruct the agent to auto-install dependencies and automatically start a persistent service and a GUI popup process that runs every 5 minutes. The runtime code forcibly sets DISPLAY and XAUTHORITY to specific values (/run/user/1000/gdm/Xauthority) and uses pkill/taskkill to terminate processes — actions that go beyond merely reading sensors and producing charts and that could interact with another user's X session or kill unrelated processes.
ℹ Install Mechanism
No archive downloads; dependencies are installed via pip (install.py invokes pip to install many packages). Installing many PyPI packages automatically is a moderate risk (network download and execution of third-party packages) but understandable for a heavy Python signal-processing tool.
⚠ Credentials
The skill requests no declared environment variables, but the code force-sets DISPLAY and XAUTHORITY to hard-coded values and writes/reads files under ~/.config/emopad and /run/user/1000/gdm/Xauthority. Hard-coded XAUTHORITY and DISPLAY values are not justified by the SKILL.md and can grant the skill access to an X server belonging to another user or require elevated access.
ℹ Persistence & Privilege
The skill auto-starts services and spawns a long-running background process that displays periodic GUI popups; auto-start behavior is declared in SKILL.md/skill.json. It is not marked always:true (so not force-included in every agent run), but it does persistently run after installation and install.py will start it automatically.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install emopad-universe
  3. After installation, invoke the skill by name or use /emopad-universe
  4. Provide required inputs per the skill's parameter spec and get structured output
