Conciseness

The body is mostly efficient - numbered steps, tables, and code with sparse, Qt-specific commentary - but a few tokens don't earn their place: Step 9 ("Parsing results") largely repeats Step 8's "-o results.xml,junitxml" command, the QTRY_VERIFY default-5-second-timeout sentence appears nearly verbatim in both Step 5 and references/qt-gui-signal-benchmark.md, and editorial asides like "clunkier than Playwright's await-everywhere model" could be trimmed. This fits the 4 anchor (efficient with minor trims possible); it is not 5 because not every token earns its place, and not 3 because nothing explains concepts Claude already knows.

Actionability

Guidance is copy-paste ready throughout: complete CMake ("find_package(Qt6 6.5 REQUIRED COMPONENTS Test Widgets)" through "add_test"), a full test class with the moc include, a working _data() slot with QTest::newRow rows, a GUI example using QTest::keyClicks/mouseClick/qWaitForWindowExposed, a QSignalSpy assertion example, and runnable CLI invocations ("./test_calculator -functions", "./test_calculator -o results.xml,junitxml"). The CI YAML in the reference completes the common cases - matching the 5 anchor for fully executable, copy-paste-ready coverage.

Workflow Clarity

Steps 1-10 form a coherent build -> author -> entry-macro -> data-driven -> GUI -> signals -> benchmark -> run -> parse -> CI sequence, and Step 2 embeds a real validation feedback loop: "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." The Anti-patterns table adds error->fix pairs for the common failure modes. This matches the 5 anchor (explicit validation steps with error-recovery loops); there are no checkpoint gaps that would justify a 4.

Progressive Disclosure

The SKILL.md spine stays lean and delegates detail to a single one-level-deep reference, references/qt-gui-signal-benchmark.md (verified to exist), linked with purpose statements in Steps 5 ("the full function-family table is in..."), 7 ("Example slot:..."), and 10 ("Full workflow:..."). The GUI function-family table, benchmark example, and CI workflow are appropriately split out, and the reference file itself links back to SKILL.md. Clear overview, well-signaled references, easy navigation - the 5 anchor.

Specificity

Enumerates the framework's full feature surface with concrete API names: "Qt Test entry macros, private-slot test functions, QVERIFY, QCOMPARE and data-driven QFETCH, simulated mouse, key and touch events, QSignalSpy, QBENCHMARK and JUnit XML output for CI". This is comprehensive coverage with no meaningful gaps, matching the anchor for multiple specific concrete actions rather than the 'minor gaps' of a 4.

Completeness

Explicitly answers both questions: the when is "Use whenever Qt C++ code needs unit or GUI tests in-process" and the what is the enumerated capability list. Both are concrete and explicit with trigger phrases, matching the 5 anchor; the when is specific (in-process, for CI) rather than the looser 'could be more explicit' case of a 4.

Trigger Term Quality

Natural user phrasings are thoroughly covered: "Qt C++ code", "unit or GUI tests", "QSignalSpy", "QVERIFY", "QCOMPARE", "QFETCH", "QBENCHMARK", "JUnit XML", "Qt Quick and QML" - exactly the terms someone writing Qt tests would say, with synonym coverage across unit/GUI/QML vocabulary. No commonly-used natural variation is missing, so it fits the 5 anchor rather than 4.

Distinctiveness Conflict Risk

"Qt C++", "in-process", and Qt-only macros (QFETCH, QSignalSpy, QTEST_MAIN) carve a clear niche that will not fire for generic C++ runners like GoogleTest or for out-of-process UI drivers. Minimal conflict risk fits the 5 anchor; it is a distinct trigger domain, not merely 'mostly distinct' as at 4.
