Conciseness

The ~19-line body is lean with zero padding: every step adds non-obvious information (failure-mode catalog, continuity checks, copy-truth rule) and no concepts Claude already knows are explained. Matches anchor 5 (every token earns its place); there is nothing to trim.

Actionability

For an instruction-only skill the guidance is concrete: step 2 enumerates specific failure modes ("missing route, unchecked `fetch` response, fake progress timer, unpersisted write, wrong ID passed forward") and the exit criteria names independent verification channels ("database, admin count, provider"). It stops short of fully executable guidance — "Fix so the outcome happens" leaves the how open and no commands/snippets are given — so anchor 4 fits better than 5.

Workflow Clarity

The six-step procedure is clearly sequenced (define end state → locate break → fix → avoid known incomplete fixes → continuity → copy truth) and the Exit criteria section is an explicit validation checkpoint requiring an independent read. It lacks an explicit error-recovery loop (what to do when exit criteria fail), which keeps it at anchor 4 rather than 5; the destructive/batch cap does not apply since verification is present and operations are not batch/destructive.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and needs no external references; the two well-organized sections (Procedure, Exit criteria) satisfy the simple-skill exception for a top score. The `qa-journey-e2e` mention is a counterpart-skill pointer, not a buried or nested reference, so navigation is clean.

Specificity

"Restore a broken customer journey" plus concrete outcome criteria ("the record is created and owned, the email arrives, the entitlement is granted") and named journey types ("signup, intake, progress, checkout, delivery") list several specific capabilities with only minor coverage gaps. It exceeds anchor 3 (only 1-2 concrete actions) but the action set centers on a single verb, so it is not the comprehensive multi-action coverage of anchor 5.

Completeness

The 'what' is explicit ("Restore a broken customer journey so the real end outcome happens... not just the visible signal") and the 'when' is an explicit "Use for..." clause with concrete trigger phrases. This matches anchor 5, which requires both what and when with concrete triggers; anchor 4's caveat about a less-specific 'when' does not apply.

Trigger Term Quality

Natural user phrasings like "button does nothing" and "says success but nothing happened" are exactly how users describe these bugs, and the stage list (signup, intake, progress, checkout, delivery) covers the domain's synonyms comprehensively. No relevant natural term family is missing within this skill's scope.

Distinctiveness Conflict Risk

The visible-signal-vs-real-outcome framing and quoted failure phrases give it a distinct niche, but broad trigger terms like "signup" and "checkout" carry minor overlap risk with general web-debugging skills and its tester counterpart `qa-journey-e2e`. Anchor 4 (mostly distinct, minor overlap with closely related skills) fits better than anchor 5's minimal-conflict bar.
