Claude Code rules are the canonical agent guidance for this repository. Codex inherits them instead of maintaining a second copy.
Before inspecting or changing files, read:
CLAUDE.md.- Every
.claude/rules/*.mdfile withoutpathsfrontmatter. - Every rule whose
pathspatterns match the files being inspected or changed.
If the scope expands, load the newly matching rules before continuing. Do not load unrelated path-scoped rules by default.
Conflicts resolve in this order: current user instructions, this file,
CLAUDE.md, matching .claude/rules/*.md, then default agent behavior.
Update the canonical Claude rules rather than duplicating guidance here.
