Conciseness

The body is dense and Ginkgo-specific (the construction-time evaluation gotcha is genuinely non-obvious), but it restates some baseline Ginkgo documentation (DescribeTable mechanics, the EntryDescription table), repeats the BeforeSuite warning twice ('a loop reading a BeforeSuite-populated slice generates zero specs' and 'Don't load it in BeforeSuite — it's too late, and the loop generates no specs'), and contains typos ('Perfer `DescrtibeTable`'). Mostly efficient with minor trims available — the 4 anchor, not 5; not 3 because nearly all content is skill-specific rather than generic padding.

Actionability

Every section carries complete, executable Go examples covering the common cases: the WRONG/RIGHT contrast for the nil-shelf gotcha, the four Entry description mechanisms in one runnable table, DescribeTableSubtree, and the TestXxx fixture-loading pattern with a pre-RUNSpecs assertion ('g.Expect(fixtureBooks).NotTo(BeEmpty())'). Copy-paste-ready throughout; matches the 5 anchor.

Workflow Clarity

Although not a sequential process skill, each section states when to apply it ('When you want a whole subtree (multiple Its, their own setup) per entry, use DescribeTableSubtree'; 'Struct-per-row for many params'), the key failure mode is explicitly flagged ('THE gotcha', 'nil pointer!'), and error recovery is shown via the WRONG/RIGHT pair. Selection guidance is clear but there is no explicit decision ordering across patterns — the 4 anchor; not 3 because the guidance that exists is coherent and error paths are concretely illustrated.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are all absent), so all ~150 lines are inline under well-organized section headers with external doc links (onsi.github.io/#table-specs etc.) and pointers to sibling skills (ginkgo:overview, ginkgo:decorators, ginkgo:filtering). Structure and signaling are good, but the body exceeds the under-50-lines condition for a 5 without external references, and all detail (DescribeTableSubtree, shared behaviors) is inlined rather than split out — the 4 anchor; not 3 because organization and navigation are genuinely solid.

Specificity

The description enumerates many specific concrete capabilities ('DescribeTable/Entry table-driven specs, Entry descriptions (string, nil, closure, EntryDescription), PEntry/FEntry and per-Entry decorators, DescribeTableSubtree, generating specs in a construction-time loop, loading fixtures in TestXxx before RunSpecs, and shared-behavior closures') in third person, comprehensively covering the skill's feature set. It clearly matches the 5 anchor; it is not 4 because coverage is complete rather than minorly gapped.

Completeness

It explicitly answers both questions: a detailed 'what' (the capability enumeration) and an explicit 'when' ('Use when you have repetitive specs differing only by inputs, want data-driven or generated specs, or are extracting reusable It blocks across Contexts'). This matches the 5 anchor with concrete trigger phrases; it is not 4 because the when-clause is explicit rather than merely present.

Trigger Term Quality

Natural trigger phrases are present ('repetitive specs differing only by inputs', 'data-driven or generated specs', 'table-driven specs', 'extracting reusable It blocks'), but the description leans heavily on API jargon (PEntry/FEntry, DescribeTableSubtree, TestXxx) and misses common synonyms a user might say such as 'table tests' or 'parameterized tests'. This sits noticeably above the midpoint between anchors 3 and 5 but is not comprehensive enough for 5.

Distinctiveness Conflict Risk

Ginkgo table-driven/dynamic spec generation is a clear niche with distinct triggers ('repetitive specs differing only by inputs') that would not naturally fire a generic testing or Ginkgo-overview skill. It matches the 5 anchor; overlap with sibling Ginkgo skills (ginkgo:overview, ginkgo:decorators) is minimal and the triggers are specific to this skill's scope.
