name	journal-rank
description	Use when the user asks about a journal's tier / ranking / indexing — "what tier is this journal", "中科院分区", "JCR 几区", "影响因子", "impact factor", "是不是 SCI/SSCI", "这个期刊收录情况", "what quartile is this". Looks up the focused item's journal ranking from an authoritative source (NEVER from memory — these numbers are easy to hallucinate) and can write it back to the item as tags or a note.

Journal ranking / indexing

The user wants a journal's tier and indexing — 中科院分区 (CAS quartile), JCR quartile (Q1–Q4), impact factor, and indexing status (SCIE / SSCI / EI / CSCD / CSSCI / Scopus). This is high-value for the user's audience, and high-risk: tier and IF numbers are exactly what a model invents confidently. The cardinal rule: look it up and cite the source + year — never state a 分区/IF from memory.

Step 1 — identify the journal

Get the focused item and its journal name:

• zotero_get_open_reader_state (else zotero_get_selected_items) → the item.
• The journal is the item's publicationTitle field (read it via zot if needed). If no journal is in scope, ask the user which journal, or accept a journal name / ISSN they type.

Step 2 — look it up (do NOT recall from memory)

Find the ranking from an authoritative source, in this order:

1. A pre-collected dataset, if the user has one wired (e.g. a zot journal-rank table / lookup tool, or a local 分区 dataset). Preferred when present — it's the local-first, citable path.
2. A search / web / academic lookup the user has wired into pi (web-search MCP, publisher pages, JCR/中科院分区 references) — query by journal name and/or ISSN.
3. None available — say so: "I can't look up the ranking without a dataset or a search source wired — and I won't guess these numbers from memory." Stop there.

Whatever the source, report which source and which year (分区 is reassessed yearly and CAS vs JCR differ; CAS also has 基础版 vs 升级版). A ranking without a year is useless and misleading.

Step 3 — fill it in (optional, on request)

If the user wants it saved to the item:

• Preferred: tags via zotero_apply_tags (if available) — e.g. 中科院一区, JCR Q1, IF 12.3 (2023), SCIE. Tags are filterable in Zotero, which is the point.
• Fallback: a note via zotero_add_note_to_current_item — a short block with the ranking, source, and year. Confirm in ~1 line after writing; don't re-paste everything.

Anti-patterns (do NOT do these)

1. Stating 分区 / IF from memory. This is the whole risk. If you didn't look it up this turn from a real source, you don't know it. Refuse rather than guess.
2. Dropping the year / version. Always say the year and whether it's CAS or JCR (and 基础版/升级版 if known). Rankings change; an undated number is wrong-by-default.
3. Conflating systems. 中科院分区 (1–4 区) ≠ JCR quartile (Q1–Q4) ≠ impact factor ≠ indexing (SCIE/SSCI/…). Keep them distinct; don't translate one into another.
4. Writing unverified values to the item. Only tag/note a ranking you actually sourced this turn. A wrong tag is worse than no tag.
5. Reimplementing zot. If a dataset/lookup belongs in the data layer, that's zot's job; this skill orchestrates the lookup and writes the result back.
