Skill2 starsChanged todayApache-2.0View on GitHub

Safe inlining and removal of single-use functions during code review and refactoring. Use when a local, non-exported helper has exactly one real call site and inlining preserves behaviour and readability.

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use this skill when reviewing or editing cleanup/refactor changes that inline and remove functions used exactly once:

    line 9
  2. Very specific:

    Do not introduce any.

    line 16
  3. Very specific:

    Do not use the non-null assertion operator (!).

    line 17
  4. Distinctive:

    Do not add unnecessary comments or abstractions.

    line 18

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Remove Single-Use Functions

Use this skill when reviewing or editing cleanup/refactor changes that inline and remove functions used exactly once:

  • The function must be local and non-exported.
  • The function must have exactly one real call site after the current change set is applied.
  • Preserve runtime behavior, types, and existing style.
  • Skip public APIs, framework hooks, callbacks, overloaded or generic utilities, and test helpers kept for readability.
  • Safe cleanup means inlining the function at its sole call site and then removing the original function definition.
  • Do not introduce any.
  • Do not use the non-null assertion operator (!).
  • Do not add unnecessary comments or abstractions.
