Conciseness

The body is dense and actionable with almost no generic-concept padding, but there is minor trimmable redundancy: Step 9 largely repeats Step 8's './test_calculator -o results-junit.xml,junitxml' command, and 'A test can be executed multiple times with different test data. Each newRow runs the test function once.' restates doc-level knowledge. This is the 'efficient; minor instances of over-explanation that could be trimmed' anchor (4) rather than the lean 5 anchor, and clearly above the 3 anchor's 'some unnecessary explanation'.

Actionability

Every stage ships copy-paste-ready material: the CMake qt_add_executable block, a complete QObject test class with lifecycle slots and the moc include, a full data-driven QFETCH/_data() pair, a runnable GUI test with qWaitForWindowExposed/keyClicks/mouseClick/QTRY_VERIFY, a QSignalSpy example, and the -functions/-v2/-o CLI commands, plus an anti-patterns table with concrete fixes. Matches the 'fully executable; copy-paste ready; covers the common cases' anchor, not 4, since no key detail is missing.

Workflow Clarity

Steps 1-10 give a clear author->build->run->parse->CI sequence, with an explicit validation feedback loop in Step 2 ('run ./test_calculator -functions; confirm it lists your private-slot test functions... If none appear, the slots are not under private slots: or the #include "tst_*.moc" line is missing - fix and rebuild') and an anti-patterns table that provides diagnose-and-fix recovery for the known failure modes. Matches the 5 anchor's 'explicit validation steps; feedback loops for error recovery', not the 4 anchor's 'minor validation gaps'.

Progressive Disclosure

The single bundle file, references/qt-gui-signal-benchmark.md, exists at the cited path, is one level deep, and is clearly signaled three times with what it holds (the GUI function-family table in Step 5, the benchmark example slot in Step 7, the full CI workflow in Step 10), and the reference links back to the SKILL. The core flow stays in the body while heavier detail is split out - matching the 5 anchor's 'well-signaled one-level-deep references; content appropriately split', not the 4 anchor's 'minor organization gaps'.

Specificity

The description enumerates concrete, named capabilities - 'QTEST_MAIN / QTEST_APPLESS_MAIN / QTEST_GUILESS_MAIN entry-point macros', 'QVERIFY / QCOMPARE / QFETCH assertions', 'GUI event simulation (QTest::mouseClick, QTest::keyClick, QTest::touchEvent)', 'QSignalSpy for signal introspection', 'QBENCHMARK for performance regression', and '-o file,junitxml CI output' - giving comprehensive coverage of the framework's surface with no vague padding. This matches the 'lists multiple specific concrete actions; comprehensive coverage' anchor, not the 4 anchor, because there are no material coverage gaps.

Completeness

It explicitly answers both: what - 'Authors and runs Qt Test - the first-party C++ unit + GUI test framework that ships with Qt 6' with a detailed capability list; and when - 'Use for in-process testing of Qt widgets, QObject signal/slot chains, and Qt Quick / QML application logic; for out-of-process Qt-app driving, use an OS-native accessibility driver instead.' The explicit 'Use for' clause with concrete trigger phrases (and a negative boundary) matches the 5 anchor exactly, not 4 where 'when' could be more specific.

Trigger Term Quality

Good natural-keyword coverage: 'Qt Test', 'QtTest', 'C++ unit + GUI test framework', 'Qt 6', 'Qt widgets', 'QObject signal/slot', 'Qt Quick / QML', 'benchmark', 'junitxml'. A few natural user phrasings are still missing (e.g., 'Qt unit testing', 'widget testing', 'tst_', 'ctest', 'headless'), so it sits between the 4 and 5 anchors - noticeably above the midpoint but not comprehensive, hence 4.

Distinctiveness Conflict Risk

It carves a clear niche - the first-party Qt 6 in-process test framework - and actively disambiguates by redirecting out-of-process Qt-app driving to 'an OS-native accessibility driver instead', minimizing overlap with generic C++ test skills and GUI-driver skills. Minimal conflict risk, matching the 5 anchor.
