report-evaluation
Evaluate student assignment reports using three independent reviewers for consensus grading. Each reviewer reads the PDF and context files independently, then provides section assessments in Swedish. Results compiled with majority voting into GRADING-RESULTS.md. Use when grading prepared student submissions.
exercise-designer
Designs deliberate practice exercises applying evidence-based learning strategies like retrieval practice, spaced repetition, and interleaving. Activate when educators need varied exercise types (fill-in-blank, debug-this, build-from-scratch, extend-code, AI-collaborative) targeting learning objectives with appropriate difficulty progression. Creates exercise sets that apply cognitive science principles to maximize retention and skill development. Use when designing practice activities for Python concepts, creating homework assignments, generating problem sets, or evaluating exercise quality.
aoc
Solve Advent of Code puzzles, algorithm challenges, and competitive programming problems. Activate when user provides AoC problem context/input, mentions solving puzzles/challenges, asks about algorithm selection (BFS, DFS, DP, etc.), or needs help with parsing structured input.
emerging-tech
Emerging technologies (prompt engineering, AI agents, red teaming) and leadership roles (product manager, engineering manager, DevRel, UX design, technical writing).
simulation-code-validation
Encodes validation patterns for robotics simulation code (ROS 2, Gazebo, Isaac Sim). Ensures code examples are testable, safe, and follow simulation-first pedagogy. Validates Python syntax, ROS 2 patterns, URDF/SDF markup, and troubleshooting completeness.
