Conciseness

The body is pure flag listings with defaults and one-line effects ('`SQLITECPP_USE_ASAN` (OFF): address sanitizer') with zero padding and no explanation of concepts Claude already knows. It matches anchor 5 — lean, efficient, every token earns its place.

Actionability

Concrete flag names, defaults, and effects are given for every option, which is actionable for a build-configuration task, but no example invocation (e.g., `cmake -DSQLITECPP_INTERNAL_SQLITE=ON ..` or the meson equivalent) is shown. This matches anchor 4 (concrete guidance with minor gaps) rather than 5, which expects copy-paste-ready commands.

Workflow Clarity

As a simple single-purpose lookup skill under 50 lines it is clearly sectioned by build system, but the CMake section lists `SQLITECPP_DISABLE_EXPANDED_SQL` while the Meson section lists `SQLITECPP_DISABLE_SQLITE3_EXPANDED_SQL` with no clarification of the name difference, and there is no hint for verifying a flag took effect. This places it at anchor 4 rather than 5, where the single action would be fully unambiguous.

Progressive Disclosure

The skill is under 50 lines, needs no external references (none exist in the bundle), and the body is organized into clear sections per build system and category. Per the rubric's simple-skill guideline, well-organized sections with no needed references score 5.

Specificity

The description names the domain precisely ('SQLiteCpp and sqlite3 feature flags for CMake and Meson builds') but is a noun phrase with no concrete action verbs — it describes a topic rather than what the skill does. It matches anchor 2 (domain named, actions minimal or generic) rather than 3, which requires 1-2 concrete actions to be listed.

Completeness

The 'what' is clear (feature flags for SQLiteCpp/sqlite3 across CMake and Meson builds), but there is no 'Use when...' clause or equivalent trigger guidance, which per the judging guidelines caps completeness at 3. It is not 4 because the 'when' is entirely absent rather than merely imprecise.

Trigger Term Quality

Terms like 'SQLiteCpp', 'sqlite3', 'feature flags', 'CMake', and 'Meson' are exactly what a user needing this skill would naturally say, giving good keyword coverage across both build systems. It falls short of anchor 5 because natural synonyms such as 'build options', 'compile definitions', or 'SQLCipher' are absent.

Distinctiveness Conflict Risk

The combination of SQLiteCpp, sqlite3, CMake, and Meson defines a clear niche with distinct triggers and minimal risk of colliding with other skills. Anchor 5 is the best fit; anchor 4 would require some overlap risk with closely related skills, which is not present here.
