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.

安全使用建议
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.
功能分析
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.
能力评估
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.
