Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
This module detects AprilTag fiducial markers for camera calibration and pose estimation.
from pywayne.cv.apriltag_detector import ApriltagCornerDetector # Create detector detector = ApriltagCornerDetector() # Detect from file path detections = detector.detect('test.png', show_result=True) # Detect from numpy array import cv2 image = cv2.imread('test.png') detections = detector.detect(image)
Detect AprilTags in an image: detections = detector.detect( image, # File path, Path object, or numpy array show_result=False # Show visualization window ) Returns list of detection results with: id: Tag ID hamming_distance: Detection confidence center: Tag center coordinates (x, y) corners: 4 corner coordinates
Detect AprilTags and draw results on original image: result_image = detector.detect_and_draw(image) cv2.imshow('Detection Result', result_image) cv2.waitKey(0) Visualization includes: Green polygon outlines Red corner circles Red ID labels at tag centers
cv2 (OpenCV) - Image processing numpy - Array operations gettool - Downloads apriltag_detection library automatically
The detector automatically checks for and installs the apriltag_detection library using gettool if not found.
Each detection contains: FieldDescriptionidTag identifierhamming_distanceHamming distance (lower = more confident)centerTag center as (x, y) tuplecorners4 corner coordinates as [(x1, y1), (x2, y2), (x3, y3), (x4, y4)]
Supports both grayscale and BGR images Automatic grayscale conversion for detection Visualization sizes scale with image dimensions Uses AprilTag 36h11 tag family
Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
