Conciseness

The body is lean and operational throughout — e.g. "The workflow disables code signing. It does not archive, export or deploy an app." and the dense env/step tables — with no explanations of concepts Claude already knows. Every sentence carries setup or dispatch information, matching the 'every token earns its place' anchor.

Actionability

Copy-paste-ready commands cover all three dispatch cases ("gh workflow run mac-run.yml -f step=build/test/screenshots") and configuration is concrete ("Replace the `App` placeholder", "Screenshots require a concrete simulator"). Not 5 because the run-monitoring and artifact-retrieval steps have no commands (e.g. `gh run watch` / `gh run download mac-run`), leaving a minor gap in the executable flow.

Workflow Clarity

The section order gives a clear sequence (install → configure env → commit to default branch → dispatch → artifact), but checkpoints are missing or implicit: there is no pre-dispatch validation that XCODE_SCHEME is shared and XCODE_DESTINATION is available, and no step to verify the run succeeded before expecting the artifact. Failure behavior is described ("A failing command fails the run and keeps its log for upload") but there is no validate/fix/retry loop, so it fits the 'sequence present but checkpoints missing or implicit' anchor rather than the 'most checkpoints present' anchor at 4.

Progressive Disclosure

The body is short and well-sectioned with clearly signaled, one-level-deep references ("[templates/mac-run.yml](templates/mac-run.yml)" and "scripts/install.sh"). However, scoring against the actual bundle structure, the primary referenced payload templates/mac-run.yml is absent (only scripts/install.sh exists), so the central link is broken and scripts/install.sh's "cat -- "$SCRIPT_DIR/../templates/mac-run.yml"" would fail — a real navigation failure rather than a minor organization gap, which rules out 4.

Specificity

"install or dispatch a macOS GitHub Actions build, test or simulator screenshot run" names the domain and several concrete actions (install, dispatch, build, test, simulator screenshot), matching the 'several specific actions; minor gaps' anchor. It is not 5 because it omits that runs return logs and PNG artifacts, a core capability stated in the frontmatter summary.

Completeness

The "what" is clear ("install or dispatch a macOS GitHub Actions build, test or simulator screenshot run for an Xcode project") but there is no "Use when..." clause or equivalent explicit trigger guidance; the "when" is only weakly implied by "Load to install or dispatch". Per the judging guideline, a missing 'Use when' clause caps completeness at 3.

Trigger Term Quality

Natural terms users would say are present: "Xcode", "build", "test", "simulator screenshot", "GitHub Actions", "macOS". Not 5 because common variations such as "CI", "workflow run", or "Swift" are missing, so keyword coverage is good but not comprehensive.

Distinctiveness Conflict Risk

"macOS GitHub Actions ... for an Xcode project" plus "simulator screenshot" define a clear niche with distinct triggers, so it is unlikely to fire for the wrong skill (local xcodebuild requests or generic CI requests are distinguishable because GitHub Actions and Xcode are both named).
