Conciseness

The body is dense and mostly earns its tokens (tables, templates, benchmarks rather than explanations of concepts Claude already knows), but there is real duplication: 'Questions to Ask' repeats the 'Before Starting' checklist, 'Target Benchmarks' repeats Section 6 metrics, and the external-link reach penalty appears in both Section 7 and Section 10. Time-sensitive figures ('LinkedIn Algorithm (2026)', '47% of B2B marketers plan to increase... in 2026') are not isolated in a dated/deprecated section, which the guidelines penalize. This fits the 'mostly efficient but could be tightened' anchor — better than the noticeably-verbose anchor below it, short of 'minor instances that could be trimmed' above it.

Actionability

Guidance is concrete and directly usable: full DM templates with day-by-day sequence architecture, boolean search patterns, filter stack combinations, headline formulas, a minute-by-minute daily routine, numeric benchmarks, and cause→fix troubleshooting. For an instruction-only skill this is copy-paste-ready across the common cases, matching the top anchor; it is not a 4 because the templates and routines cover the full workflow end-to-end rather than leaving minor gaps.

Workflow Clarity

The 4-stage flow (POST → ENGAGE → DM → CALL) with a diagram, a 'Before Starting' confirmation checklist, explicit DM-timing rules, buying-signal triggers for stage transitions, and a STOP rule after 3 unanswered follow-ups gives a clear sequence with most checkpoints present. It is not a 5 because checkpoints are largely implicit rather than explicit validation loops (e.g., no 'verify profile audit passed before building sequences' style gates), though this is advisory work, not a destructive/batch context, so no cap applies.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are all absent) and the skill is a ~420-line single document with no external references. Section headers and a Quick Reference provide decent navigation, but content that naturally belongs in separate files — the DM template library, the tool comparison table, the metrics dashboards — is fully inlined, matching the anchor 'some structure but content that should be separate is inline.' It is not a 2 because the document is genuinely well-organized and navigable, not a wall of text.

Specificity

Lists several concrete actions — "sell through social media, optimize LinkedIn for sales, build DM sequences, or convert content engagement into pipeline" plus "profile optimization through DM-to-deal conversion" — matching the anchor for several specific actions with minor gaps. It is not a 5 because the third sentence ('This skill covers social selling strategy from profile optimization through DM-to-deal conversion') largely restates the first rather than adding new concrete capabilities, padding rather than extending coverage.

Completeness

Explicitly answers both what ("This skill covers social selling strategy from profile optimization through DM-to-deal conversion") and when ("When the user wants to sell through social media... Also use when the user mentions..."), with concrete trigger phrases and an explicit negative boundary ("Do NOT use for technical implementation, code review, or software architecture"). Clearly matches the top anchor rather than the score-4 anchor where 'when' could be more explicit.

Trigger Term Quality

Comprehensive natural trigger phrases users would actually say: 'social selling,' 'LinkedIn selling,' 'LinkedIn DMs,' 'social prospecting,' 'LinkedIn Sales Navigator,' 'DM sequences,' 'LinkedIn outreach,' 'social pipeline,' 'LinkedIn optimization.' This matches the anchor for comprehensive coverage including synonyms and variations; it does not miss any common phrasing of the domain.

Distinctiveness Conflict Risk

Clear niche (LinkedIn/social selling) with distinct named triggers and an explicit do-not-use clause that separates it from adjacent technical or content-strategy skills. Minimal conflict risk, matching the score-5 anchor; it is well above the score-4 anchor ('minor overlap risk with closely related skills') because the exclusions are stated outright.
