Lean body that assumes competence — no explanation of what logging or unified logging is — with concise code and tight guideline bullets; every section earns its place without padding.

Provides copy-paste-ready Swift Logger code and concrete executable commands such as 'log stream --style compact --predicate' and './script/build_and_run.sh --telemetry', with specific subsystem/category examples.

A clear 5-step workflow with an explicit verification step (step 4) and a feedback loop in step 5 ('If it does not fire, move the log closer ... and rerun'), reinforced by a Verification Checklist.

A single-purpose skill with no bundle files and well-organized sections (Quick Start, Core Guidelines, Minimal Logger Pattern, Workflow, Verification Checklist, Guardrails); per the simple-skills note, clear organization without external references supports a top score.

Names multiple concrete actions — 'Add lightweight runtime telemetry and debug instrumentation to macOS apps, then verify those events after building and running' — plus specific instrumentation targets like wiring Logger and adding log points for window/sidebar/menu-bar actions.

Explicitly answers both what (add and verify telemetry) and when via a clear 'Use when wiring ... adding log points ... reading runtime logs ... or confirming that expected events fire' trigger clause.

Includes natural terms a user would say — 'wiring Logger / os.Logger', 'reading runtime logs from Console or log stream', 'confirming that expected events fire' — covering the real vocabulary of the task.

The macOS-specific logging niche with distinct triggers (Console, log stream, os.Logger, build/run verification) makes it unlikely to fire for unrelated skills.
