Conciseness

The body is lean and dense — decision tables, terse bullets, and zero padding or explanation of concepts Claude already knows ('Links fix an authority gap. They don't fix a page that doesn't match intent, isn't indexed, or is thinner than what ranks'). The single date ('updated 2026-08-28') is a currency marker paired with a re-check instruction in references/risk-policy.md, not stale conditional guidance, so it does not read as time-sensitive branching logic.

Actionability

Fully actionable for an instruction-only skill: a diagnosis table ('What you see → What it means → Do this'), observable qualification signals ('organic traffic that isn't collapsing... Skip sites whose outbound links are mostly unrelated commercial anchors'), a spec for outreach copy ('what you noticed, why your resource helps their readers, one ask'), a 7-item deliverables list, and a metric/cadence table. Per the rubric's code-vs-instruction note, the absence of code is not penalized since the guidance is executable.

Workflow Clarity

A clearly sequenced workflow (Before Starting → Steps 1–7 → loop → tools → output) with explicit validation gates: diagnose before outreach (Step 1), qualify before writing (Step 4), and 'Don't send outreach on the user's behalf without explicit approval of the list and the copy,' plus a measurement feedback loop with weekly funnel and monthly outcome cadence.

Progressive Disclosure

The body is an overview with decision tables and policy stances, while executable details (search strings, templates, vendor checks) are split into three real, substantive reference files — tactics.md, prospecting-and-outreach.md, risk-policy.md — each clearly signaled and directly one level deep ('Playbooks for each tactic... are in references/tactics.md'). Verified against the actual bundle: all referenced paths exist and contain the promised content; cross-links between references are lateral, not nested chains.

Specificity

The description names several concrete actions through its capability statement and trigger list — 'earn backlinks or third-party mentions that lift rankings and AI citations,' 'link reclamation,' 'broken link building,' 'guest posting,' 'is this link vendor safe' — matching the 'several specific actions; minor gaps' anchor. Not 5 because the headline what-clause is a single composite action rather than a comprehensive enumeration of the skill's activities.

Completeness

Explicitly answers both what ('earn backlinks or third-party mentions that lift rankings and AI citations') and when ('Use this whenever rankings stall on authority or someone wants off-site mentions that AI engines cite,' plus the enumerated trigger list), with concrete trigger phrases — matching the anchor-5 example pattern.

Trigger Term Quality

Comprehensive natural-term coverage with spelling variants and colloquial phrases users would actually say: 'link building,' 'linkbuilding,' 'backlinks,' 'get more backlinks,' 'unlinked mentions,' 'get into best-of lists,' 'competitor backlinks,' 'is this link vendor safe.' Matches the 'comprehensive coverage of natural terms including synonyms' anchor.

Distinctiveness Conflict Risk

Clear niche (off-site link earning) with distinct triggers and explicit boundary routing to adjacent skills ('For press coverage and journalist requests, see public-relations. For directories, see directory-submissions. For reviews, see referrals...'), minimizing wrong-skill triggering.
