State the problem with its constraints such as time complexity, space complexity, and accuracy targets. The skill defines the hypothesis, selects the optimal language, implements complete compilable code, and verifies correctness with assertions or formal logic.

For HPC and simulations, C++20 or Fortran is recommended due to zero-cost abstractions, SIMD, and OpenMP support. The skill's selection matrix maps domains to languages: Rust or Ada for safety-critical work, Go or Rust for distributed systems, Julia for symbolic math.

No. HTML is a context-free language, not a regular language, so regex-based parsing fails on nested tags. The correct approach uses a dedicated parser such as lxml or BeautifulSoup in Python, or gumbo in C.

It ends the response with a continuation marker stating the part number and waits for the user to say continue. It then resumes exactly where it stopped while maintaining full context of the implementation.

A Michael-Scott lock-free queue guarantees lock-freedom but not wait-freedom, and naive implementations face the ABA problem. Mitigation requires tagged pointers or careful memory reclamation, plus explicit acquire/release memory ordering on atomic operations.
