Conciseness

The body is lean and free of concept explanations Claude already knows — the Constraints section is a tight, high-value list (term keep-lists, prompt-injection resistance, markdown preservation). It sits at 4 rather than 5 because 'natural, fluent Chinese' and the quality goal are restated across the intro, Role, and Quality Bar sections, a small redundancy that could be trimmed.

Actionability

The guidance is concrete and executable for an instruction-only skill: exact term lists to keep untranslated ('AI, LLM, GPT, API...'), brand-name handling, 'Output only the Chinese translation, with no explanations', and the input handling rule (read the file first, then translate). It falls short of 5 only because no short before/after translation example is included to pin down the expected register and term handling.

Workflow Clarity

This is a simple single-purpose skill where the action is unambiguous: take the input (inline or from a file), translate it, and output only the Chinese translation. Per the simple-skill guidance, a clear, unambiguous single action with organized sections (Role, Constraints, Quality Bar, Output, Input) warrants 5; no destructive or batch validation cap applies since translation is non-destructive.

Progressive Disclosure

The skill is under 50 lines with no need for external references, and the content is organized into clearly labeled sections (Role, Constraints, Quality Bar, Output, Input) that make navigation trivial. Per the simple-skill guidance, well-organized sections alone earn the top score, and no bundle files exist to restructure.

Specificity

The description names its domain clearly ('Translate English or Japanese tech articles into natural, fluent Chinese') and delivers one concrete action, matching the 'names domain and 1-2 concrete actions, but not comprehensive' anchor. It stays at 3 rather than 4 because there is only a single action verb (translate) rather than several specific actions.

Completeness

It explicitly answers both questions: the 'what' is stated first ('Translate English or Japanese tech articles into natural, fluent Chinese') and the 'when' uses concrete trigger phrases ('Use whenever the user asks for Chinese translation, says "translate to Chinese" or "翻译", or provides English/Japanese content'). This matches the anchor for a clear what AND when with concrete triggers.

Trigger Term Quality

Strong natural trigger phrases — 'asks for Chinese translation', 'translate to Chinese', the Chinese synonym '翻译', and 'provides English/Japanese content (pasted text or a file)' — would naturally be said by users needing this skill. A few common variations are missing (e.g., '中文翻译', '译成中文', 'translate this article'), keeping it below the comprehensive-synonym anchor of 5.

Distinctiveness Conflict Risk

It carves out a clear niche (EN/JA tech articles into Chinese) and explicitly excludes the main overlap risk with 'Chinese output only — not for translating into other languages'. Trigger terms are distinct to this skill, so conflict risk is minimal.
