matrix-calculus
by Victorrustless969
Matrix calculus tutorial and reference based on Jan R. Magnus' "A gentle introduction to matrix calculus". Provides tools, theorems, and worked examples for matrix differential calculus including trace, Kronecker product, vec operator, commutation matrix, duplication matrix, first and second derivatives, optimization, and applications in statistics and econometrics. Use when users ask about matrix derivatives, matrix differential calculus, optimization with matrices, Kronecker products, vec operators, or need help solving matrix calculus problems.
theory2-physics
by slapglif
Use when performing mathematical physics computations - Lie algebras, quantum chemistry, neural operators, theorem proving, or scientific validation. Provides guidance on Theory2 CLI usage, computational workflows, and verification methodology.

direct-response-copy
by Growth4U-systems
"Write copy that converts. Use when writing landing pages, emails, sales copy, headlines, CTAs, social posts, or any persuasive content. Triggers on: make this convert, write copy for X, help me sell X, punch this up, write a landing page, write sales copy. Produces internet-native copy that sounds like a smart friend explaining something while quietly deploying every persuasion principle in the book. Includes complete reference material from Schwartz, Hopkins, Ogilvy, Halbert, Caples, Sugarman, and Collier."
