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.

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.
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.
| the Dnf repoquery subcommand supports has a new option for listing all user-installed packages: | |
| $ dnf repoquery --qf '%{name}' --userinstalled \ | |
| | grep -v -- '-debuginfo$' \ | |
| | grep -v '^\(kernel-modules\|kernel\|kernel-core\|kernel-devel\)$' > pkgs_a.lst | |
| In contrast to other methods, it also lists all debuginfo packages. The additional grep in the above example filters them out. | |
| To install the list on host B: | |
| $ < pkgs_a.lst xargs dnf -y install |

The NGINX Unit control API includes a /status endpoint for usage statistics. This is a solution for exposing these metrics in Prometheus format.
The application (run by Unit) queries the /status URI on the control socket and converts the JSON response into Prometheus text format. PHP and Python implementations are available.
These instructions assume an existing Unit installation with a working configuration. We will add a new listener on the default prometheus port (9090) and route it directly to the Prometheus app.
Step 0. Install the preferred Unit language module (unit-php or unit-python)
