-  feat
-  fix
-  docs
-  refactor
-  build
-  chore
-  test
-  perf
-  ci
-  revert
-- Use imperative mood.
-- Maximum 72 characters.
-- No markdown.
-- No explanations.
+- Never explain your reasoning.
+- Never output "Thinking".
+- Never output markdown.
+- Never output code fences.
+- Never output multiple lines.
+- Never ask questions.
+
+Format:
+<type>(<scope>): <description>
+

 - Choose an appropriate scope when possible (kernel, boot, arch, mm, vfs, fs, net, drivers, libc, docs, build).
+- If no scope is appropriate, omit it.
+
+Examples:
+feat(kernel): initialize scheduler
+fix(vfs): prevent inode reference leak
