Mandatory Skill Activation Hook for Claude Code

Forces Claude to evaluate and activate relevant skills before implementation. By default, Claude Code often ignores available skills entirely and proceeds with generic responses instead of leveraging specialized skill knowledge.

Problem Solved

Claude Code frequently skips skill evaluation and jumps straight to implementation, missing out on specialized context and workflows that skills provide. This hook injects a system reminder on every prompt submission that enforces a three-step sequence: evaluate → activate → implement.

Memory allocators on Alpine Linux — PHP & multi-threaded servers

Measured 2026-05-07 to 2026-05-08 on Alpine edge, x86_64, 8 cores, 14 GB RAM. PHP 8.5.6, opcache always on. Drupal 11.x-dev (7 455 vendor .php, 8 499 classes) as the realistic single-threaded workload. A small C harness (8 pthreads × 2 000 000 small mallocs) for the multi-threaded contention scenario.

11 allocators tested:
