The body is a lean deprecation notice ('Hard-deprecated. Do not invoke or route this skill...') with no padding or explanation of concepts Claude already knows; every token earns its place.

It gives a specific directive (do not invoke; route build failures to the execution, debugging, or verification workflow), but offers no executable code or commands, so it is concrete guidance that is not copy-paste ready — between level 2 and 3.

This is a simple single-task skill whose sole action — do not invoke and redirect elsewhere — is unambiguous, so per the simple-skills note workflow clarity can score 3.

The skill is under 50 lines with no need for external references, and the deprecation statement is well-organized; no bundle files exist and none are referenced, so per the scoring notes progressive disclosure can score 3.

The phrase 'Build Fix deprecated shim' names a domain (build fix) and a status (deprecated shim) but lists no concrete actions; it stops short of the multiple specific actions of a level-3 example yet is more than the empty abstraction of level 1.

It states what the skill is (a deprecated build-fix shim) but provides no explicit 'Use when...' trigger, so per the judging guidelines a missing trigger clause caps completeness at 2 rather than reaching the explicit what-and-when of level 3.

'Build Fix' is a natural term a user might say, but the description only offers that one phrasing plus the technical 'deprecated shim', missing common variations; it matches 'some relevant keywords but missing common variations' rather than the broad coverage of level 3.

'Build Fix' is a generic domain that overlaps with the execution, debugging, and verification workflows the body itself names, so it could trigger for the wrong skill; it is somewhat specific but not the clear niche of level 3.
