When to use

Use this skill when:

  • adding new headers or refactoring includes
  • encountering circular dependencies
  • tightening the platform boundary

Source of truth

  • docs/REPO_LAYOUT.md — dependency direction and #ifdef policy
  • docs/LIBC_POLICY.md — stdlib usage constraints

Include layering rules (must follow)

src/util/      → OS-header-free, no internal deps
      ↑
src/unicode/   → may include util; OS-header-free
      ↑
src/core/      → may include util, unicode, platform interface; OS-header-free
      ↑
src/platform/  → implements zr_platform.h; may include OS headers

Specific rules

  • src/util/** MUST be OS-header-free
  • src/unicode/** may include src/util/** only; MUST be OS-header-free
  • src/core/** may include util, unicode, and zr_platform.h; MUST be OS-header-free
  • src/platform/** implements zr_platform.h; may include OS headers

Best practices

  • Prefer forward declarations in headers to avoid deep include trees
  • Keep ABI-visible headers POD-only (fixed-width ints)
  • Ensure no OS headers are transitively included by core/unicode/util
  • Platform #ifdef exists only in platform backends and selection TU

Checklist

  • No OS headers in core/unicode/util
  • No circular includes
  • Forward declarations where possible
  • ABI headers use fixed-width types only
