Conciseness

The body is dense and efficient — bulleted checklists, a treatment table, and no padding or explanation of concepts Claude already knows (it never explains what translation or localization is). A few bullets restate standard L10N knowledge (e.g., "grammar, register, punctuation, dates, numbers, units, and address formats suit the locale"), keeping it just short of the 5 anchor's "every token earns its place".

Actionability

Concrete, directive guidance throughout: a treatment-selection table with use-conditions and risks, a termbase field list ("keep-untranslated decision; owner and approval status"), per-content-type checklists, named lifecycle states ("translation-draft, review, localized-ready, outdated, not-applicable"), and a defined output artifact list. It misses the 5 anchor only because no worked examples (e.g., a sample termbase entry or a before/after transcreation) cover the common cases.

Workflow Clarity

The 8-step production workflow is clearly sequenced with explicit validation checkpoints ("Run terminology, factual, completeness, and formatting checks", "Review in the rendered product or page context", "Complete native or specialist review at the required risk level") plus a pre-flight guard ("If the source is unstable or contradictory, report the conflict before producing many dependent translations") and a Quality Gates checklist. It is not 5 because there is no explicit validate-then-fix-then-retry feedback loop when a gate fails.

Progressive Disclosure

No bundle files exist, and the ~127-line body is well organized into clear sections (Boundaries, Prepare the Source, Treatment, Terminology, Content Types, Workflow, Quality Gates, Output, Related Skills) with no monolithic wall of text. It matches the 4 anchor ("Good structure; most content is appropriately placed"); the 5 anchor requires well-signaled one-level-deep references, and the under-50-line exception does not apply at this length.

Specificity

The description lists multiple concrete actions — "Translate, transcreate, review, or maintain" plus "source locking, glossary decisions, language style, machine-assisted workflows, legal-content safeguards, QA, and source-change synchronization" — giving comprehensive coverage of the domain. It exceeds the 4 anchor because there are no meaningful gaps in the action coverage.

Completeness

The "what" is clearly and concretely stated, but there is no "Use when…" clause or equivalent trigger guidance for this skill — the only "Use…" sentence delegates to localization-strategy. Per the rubric guideline, a missing trigger clause caps completeness at 3; it is not 4 because the "when" is only weakly implied by the action verbs.

Trigger Term Quality

Good natural keyword coverage: "translate", "transcreate", "review", "multilingual", "glossary", "machine-assisted", "QA", "localization" are phrases users would naturally say. A few common variations are missing (e.g., "terminology", "localized", "proofread"), so it falls short of the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche (translation/transcreation/review of multilingual product and marketing content) is distinct, and the description explicitly carves out localization-strategy ("Use localization-strategy for market scope, locale architecture, rollout…"), reducing the main overlap risk. It is not 5 because overlap with closely related skills like keyword-research or copywriting is not addressed, and the missing trigger clause weakens trigger-based distinctiveness.
