pyqt-core SKILL.md skillA
pyqt-core from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add codeatcode/oss-ai-skills/pyqt-core@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when working with PyQt/PySide6 QtCore - signals, slots, properties, timers, settings, file I/O.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to reduce missed signal/slot connections, wrong connection-type crashes, QSettings scope mismatches, and timer leak incidents by enforcing connection-type rules for cross-thread communication, queue-aware patterns for worker threads, scope discipline for QSettings groups/arrays, and timer lifecycle checks with parent ownership.
# PyQt Core - QtCore Module
QtCore provides core non-GUI functionality: signals/slots, timers, settings, and file I/O.
## Critical Rules (Do X Because Y)
### 1. Use QueuedConnection for Cross-Thread Signals
**Do** use `Qt.QueuedConnection` when emitting signals from worker threads to UI slots because direct connections execute in the emitter's thread, causing crashes when slots access thread-unsafe UI objects.
```python
from PySide6.QtCore import Qt, QObject, Signal, QThread
class Worker(QThread):
dataReady = Signal(dict) # Declared in worker thread
def run(self):
data = self.expensiveOperation()
self.dataReady.emit(data, Qt.QueuedConnection) # Queue to UI thread
class MainWindow(QWidget):
def setupWorker(self):
self.worker = Worker()

How to install
mdr add codeatcode/oss-ai-skills/pyqt-core@sha256:7ad8c14e0f756ac4The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
