Nature Citation — Router

Routing protocol

For a new task, load the core and matching resources below. Reuse already loaded guidance on follow-ups; load more only when the task needs it.

1. Load the manifest and the core layer

Read manifest.yaml. Then read every file listed under always_load:

static/core/principles.md — what the skill produces, the strict journal scope, the source hierarchy, and the search-quality rules.
static/core/workflow.md — the seven-step workflow and the final report format.

2. No content axis — confirm scope and language inline

Unlike the other nature-* skills, nature-citation has no fragment axis. Its variation is runtime parameters, not different content bodies:

journal scope — Nature系列 / CNS / CNS及子刊 / flagship-only. Read it from the user's wording (see core/principles.md) and pass it to the script as --scope.
user language — if the user writes Chinese or requests Chinese guidance, read static/core/chinese-mode.md (Chinese notes, English search queries).
input length — if there are more than ~10 segments, switch to the batched long-article strategy in references/script-usage.md.

State the detected scope and date limits in one short line before searching.

3. Run the workflow

Follow the seven steps in core/workflow.md: segment, parse, search, evaluate support conservatively, validate complete structured author metadata, export one reference-manager file, and generate review artifacts when useful. Put the HTML browser path first only when it was generated. Prefer scripts/nature_citation.py for the search/export when internet access is available; open references/script-usage.md for its full flag list and the long-article batch strategy. When DOI metadata lacks given names, refetch the record by PMID or verify it against the publisher rather than exporting surname-only AU fields.

Never present a paper as support merely because its title is related, and never cite a metadata-only candidate without checking the abstract or publisher page. Do not invent missing bibliographic fields.

4. Reach for references only when needed

The files under references/ are deep references, not defaults. Open them on demand per the references.on_demand table in the manifest:

running the script, full flags, long-article batching → references/script-usage.md.
turning a claim into search queries and support grades → references/search-strategy.md.
the exact Nature/CNS journal-family boundary → references/journal-scope.md.
RIS / EndNote / Zotero RDF export details → references/ris-endnote.md.
