Conciseness

Mostly dense, actionable steps, but the Overview restates concepts Claude already knows ('Qt Test is a framework for unit testing Qt-based applications and libraries... [QTest namespace] carries the verification macros') and editorial asides like 'far more robust than connecting test-internal slots and counting invocations by hand' could be trimmed. Anchor 4 (efficient, minor instances of over-explanation) rather than 5 because these instances exist; not 3 since the bulk is non-redundant specifics (entry-macro table, lifecycle slot names, CLI flags, moc dependency).

Actionability

Copy-paste-ready guidance at every stage: CMake ('find_package(Qt6 6.5 REQUIRED COMPONENTS Test Widgets)... qt_add_executable... add_test'), a complete test class with '#include "tst_calculator.moc"', a full _data() slot with addColumn/newRow, GUI simulation with 'QVERIFY(QTest::qWaitForWindowExposed(&w))', QSignalSpy usage, and concrete CLI invocations ('./test_calculator -o results.xml,junitxml'). Anchor 5 (fully executable, common cases covered) rather than 4 - the only deferred example (QBENCHMARK) is supplied as complete code in the linked reference file.

Workflow Clarity

Steps 1-10 give a clear build -> author -> run -> CI sequence, and Step 2 embeds an explicit 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 failure diagnosis. Anchor 5 (explicit validation steps, feedback loops for error recovery) rather than 4, because a genuine verify -> fix -> retry loop exists at the most fragile step (test-slot discovery).

Progressive Disclosure

The bundle reference references/qt-gui-signal-benchmark.md exists and is linked at point of use in Steps 5, 7, and 10, is one level deep, and points back only to SKILL.md. Minor gaps keep it below anchor 5: a single file carries three topics and its name ('qt-gui-signal-benchmark') does not signal that Step 10's 'Full workflow' CI YAML lives there, and the QTRY_VERIFY 5-second-timeout paragraph is duplicated nearly verbatim in both body and reference. Not anchor 3 - structure, links, and navigation are otherwise clear.

Specificity

Enumerates concrete capabilities - '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' - covering authoring, assertions, data-driven tests, GUI simulation, signal introspection, benchmarking, and CI output with no vague filler. This matches anchor 5 (multiple specific concrete actions, comprehensive coverage) rather than 4, which requires minor gaps in coverage; nothing is generic, so lower anchors do not apply.

Completeness

'Use whenever Qt C++ code needs unit or GUI tests in-process' explicitly answers when, and the colon-separated enumeration explicitly answers what. This matches anchor 5 (clearly and explicitly answers both what AND when with concrete trigger phrases) rather than 4, where the 'when' is only present but less specific.

Trigger Term Quality

Includes the natural terms a user would say or paste: 'Qt', 'C++', 'unit or GUI tests', 'Qt Test', 'QVERIFY', 'QCOMPARE', 'QSignalSpy', 'QBENCHMARK', and 'Qt Quick and QML'. Matches anchor 5's comprehensive coverage including synonyms rather than 4 ('a few natural terms missing'), since even the API macro names a user is likely to mention are present.

Distinctiveness Conflict Risk

Scoped to a clear niche - in-process Qt C++ testing - gated on 'Qt C++' and 'in-process', so it will not trigger for generic unit-testing skills or other-language GUI drivers. Matches anchor 5 ('clear niche with distinct triggers; minimal conflict risk') rather than 4, which presumes residual overlap with closely related skills.
