+description: Use when the user explicitly asks for Nature Skills, nature-skills, Nature style, Nature-style, Nature Communications, Nature-family, CNS, high-impact journal, or Springer Nature workflows, including Nature figure work, polishing, writing, reviewer critique, high-impact journal major revision response, Nature/CNS citations, Nature data-sharing workflows, paper readers, reviewer response, paper-to-PPT, submission checklist, or Nature-specific academic-search workflows.

+
+# Nature Workflow Bridge
+
+This skill is a bridge to the upstream `nature-skills` bundle, not a simplified
+clone of it. Its job is to route the user's request to the right original
+`nature-*` skill when that skill is installed or otherwise available, and to
+fall back to ScholarAIO's existing skills only when the original upstream skill
+cannot be used in the current host.
+
+## Direct-Use Policy
+
+Use the original upstream nature-* skill directly whenever it is available. Do
+not emulate, summarize, or partially rewrite upstream behavior from this bridge.
+Do not copy only SKILL.md from upstream; direct use requires the whole skill
+directory, including `manifest.yaml`, `static/`, `references/`, scripts, assets,
+and `skills/_shared` when the upstream skill references it.
+
+If the upstream skill is unavailable, say so, then use the ScholarAIO fallback
+route from `references/upstream-skill-map.md`. Mark the output as a ScholarAIO
+fallback, not as an upstream-equivalent Nature Skills result.
+
+## Reference Loading
+
+Load only what the current request needs:
+
+- `references/upstream-skill-map.md`: load for routing decisions or when the
+  request could match more than one upstream skill.
+- `references/bridge-policy.md`: load when installation, direct-use behavior,
+  upstream fidelity, or fallback limitations matter.
+- `references/upstream-install.md`: load when the user needs the original
+  upstream `nature-*` skills installed or asks whether this bridge is a
+  simplified local copy.
+- `references/quickstart.md`: load when the user asks how to use the bridge or
+  wants example prompts.
+
+## First Pass
+
+Classify the request before doing work:
+
+1. **Upstream target**: one or more of `nature-figure`, `nature-polishing`,
+   `nature-writing`, `nature-reviewer`, `nature-citation`, `nature-data`,
+   `nature-reader`, `nature-response`, `nature-paper2ppt`, or
+   `nature-academic-search`.
+2. **Availability**: original upstream skill available, installed through a
+   plugin/local skill path, or unavailable.
+3. **ScholarAIO fallback**: only if upstream cannot be used.
+4. **Evidence state**: manuscript/text/PDF/figures/comments/data/references
+   supplied, workspace available, or missing inputs.
+
+State the upstream target and whether direct upstream use is available before
+doing substantial work.
+
+## Route Table
+
+| User intent | Primary route |
+|-------------|---------------|
+| Nature/high-impact scientific figure, publication plot, manuscript figure, figures4papers-style output | `nature-figure` |
+| Nature-style polishing, manuscript prose polish, Chinese-to-English academic polish | `nature-polishing` |
+| Draft/rebuild abstract, introduction, methods, experiments, discussion, conclusion, title, or manuscript argument | `nature-writing` |
+| Pre-submission reviewer critique, mock peer review, Nature-style reviewer report | `nature-reviewer` |
+| Nature/CNS citation support, claim-to-reference mapping, reference-manager export | `nature-citation` |
+| Data Availability, repository plan, FAIR metadata, accession/DOI/source-data/code availability | `nature-data` |
+| Full-paper bilingual reader, source-grounded Markdown reader, paper translation/reading | `nature-reader` |
+| Reviewer comments, rebuttal, point-by-point response letter, major/minor revision response | `nature-response` |
+| Paper-to-PPT, Chinese journal-club PPTX, group meeting deck from a paper | `nature-paper2ppt` |
+| Multi-source literature search, citation verification, MeSH/search strategy, citation-file management | `nature-academic-search` |
+
+Submission package is only one scenario. Do not require a full submission
+package when the user asks only for polishing, figures, reading, PPT, citation
+support, reviewer critique, Data Availability, response, or search.
+
+## ScholarAIO Fallbacks
+
+When the original upstream skill is not available:
+
+- figure work -> `/draw`
+- prose polish -> `/writing-polish`
+- manuscript writing -> `/paper-writing`
+- reviewer response -> `/review-response`
+- citation/search/export -> `/search` + `/citation-check` + `/export`
+- paper reading/translation -> `/show` + `/translate`
+- paper-to-PPT or document packaging -> `/document`
+- literature search -> `/search` or `/websearch`
+
+Use fallbacks conservatively. Preserve upstream-style guardrails such as
+non-invention, source grounding, explicit missing inputs, and final-output
+verification, but do not claim to have executed the original upstream workflow
+unless the original skill was actually used.
+
+## Output Shape
+
+For routing tasks, return:
+
+1. `Upstream target:` selected `nature-*` skill or skill sequence.
+2. `Mode:` direct upstream use or ScholarAIO fallback.
+3. `Route:` exact skill sequence.
+4. `Immediate next action:` file to inspect, command to run, or question to ask.
+5. `Guardrails:` only the relevant non-invention, source-grounding, or
+   verification constraints for this request.

+# Bridge Policy
+
+This bridge integrates ScholarAIO with the upstream `nature-skills` project
+without degrading that project into a simplified local rewrite.
+
+## Direct Use Comes First
+
+Use the original upstream nature-* skill directly whenever it is installed or
+available through the current agent host. The upstream skill is the source of
+truth for its workflow.
+
+Do not emulate upstream behavior from this bridge. Do not copy only SKILL.md.
+Do not flatten upstream `static/`, `references/`, scripts, assets, or
+`manifest.yaml` into a short local summary.
+
+Direct upstream use means the whole skill directory is available, including:
+
+- `SKILL.md`
+- `manifest.yaml`, when present
+- `static/`
+- `references/`
+- scripts and assets
+- `skills/_shared` for upstream skills that reference the shared layer
+
+## What This Bridge Does
+
+- Classifies the user's request into the upstream `nature-*` skill index.
+- Preserves the upstream product language: Nature/high-impact academic workflow,
+  not submission-only.
+- Routes to the original upstream skill when possible.
+- Routes to ScholarAIO's existing skills only as a fallback or for local
+  repository-native work.
+- States clearly when a result is a ScholarAIO fallback rather than an
+  upstream-equivalent result.
+
+## What This Bridge Does Not Do
+
+- It does not vendor or rewrite the entire upstream `nature-skills` repository.
+- It does not claim that `/draw`, `/writing-polish`, `/paper-writing`,
+  `/document`, or other ScholarAIO fallbacks are identical to upstream
+  `nature-*` workflows.
+- It does not require a submission package unless the user explicitly asks for
+  one.
+- It does not invent citations, data identifiers, repository URLs, reviewer
+  expectations, journal rules, figure evidence, manuscript claims, or policy
+  details.
+
+## Upstream Installation Reminder
+
+The upstream repository explicitly warns that each skill is a folder-based unit.
+Install or reference the whole skill directory, plus `skills/_shared` when
+needed. Copying only `SKILL.md` silently breaks many upstream workflows.
+
+Upstream repository checked during this branch:
+
+```text
+https://github.com/Yuan1z0825/nature-skills.git
+local checked HEAD: 5e31dbb235fc9aca8d40dadd160583d2403dc9f7
+origin/main observed: 5e31dbb235fc9aca8d40dadd160583d2403dc9f7
+```
+
+If exact parity matters, refresh the upstream clone and inspect the current
+`README.md`, `SKILL.md`, `manifest.yaml`, `static/`, and `references/` files
+before finalizing behavior.

+# Quickstart
+
+Use `nature-workflow` when the user asks for Nature Skills, Nature-style,
+Nature-family, CNS, high-impact academic, or target-journal help and the exact
+upstream `nature-*` skill is not already obvious.
+
+Submission package is only one scenario. The bridge also covers Nature/high-impact
+figure, polishing, writing, reader, paper2ppt, academic search, citation, data,
+reviewer critique, and reviewer-response workflows.
+
+## Example Prompts
+
+```text
+/nature-workflow Polish this abstract in Nature Communications style.
+```
+
+```text
+/nature-workflow Make this paper into a Chinese journal-club PPT.
+```
+
+```text
+/nature-workflow Use Python to create a Nature-style multi-panel figure for
+these benchmark results.
+```
+
+```text
+/nature-workflow Draft a Data Availability statement and repository plan for
+this manuscript.
+```
+
+```text
+/nature-workflow Simulate a Nature-style reviewer critique for this draft.
+```
+
+```text
+/nature-workflow Add Nature/CNS-family citation support to these manuscript
+claims and export RIS.
+```
+
+## Expected First Response
+
+The bridge should first say:
+
+1. which upstream `nature-*` skill applies
+2. whether direct upstream use is available
+3. the ScholarAIO fallback if upstream is unavailable
+4. the first concrete next action

+# Upstream Install
+
+Use this reference when the user wants direct upstream Nature Skills behavior,
+asks whether ScholarAIO has copied a simplified version, or needs to make the
+original `nature-*` skills available in the current agent host.
+
+## Codex Plugin Path
+
+Install the complete upstream bundle through the Codex plugin marketplace:
+
+```bash
+codex plugin marketplace add https://github.com/Yuan1z0825/nature-skills --ref main
+codex plugin add nature-skills@nature-skills
+```
+
+Restart Codex or start a new session after installation so the `nature-*` skills
+are discovered.
+
+## Manual Local-Skill Path
+
+Clone the upstream repository:
+
+```bash
+git clone https://github.com/Yuan1z0825/nature-skills.git
+cd nature-skills
+```
+
+Install all current upstream skills as whole directories:
+
+```bash
+mkdir -p ~/.codex/skills
+cp -R skills/_shared ~/.codex/skills/
+for d in skills/nature-*; do
+  cp -R "$d" ~/.codex/skills/
+done
+```
+
+Install one upstream skill as a whole directory:
+
+```bash
+mkdir -p ~/.codex/skills
+cp -R skills/_shared ~/.codex/skills/
+cp -R skills/nature-reader ~/.codex/skills/
+```
+
+## Fidelity Rule
+
+Copy the whole skill directory. Do not copy only `SKILL.md`.
+
+The original upstream skills may rely on `manifest.yaml`, `static/`,
+`references/`, scripts, assets, README context, and `skills/_shared`. A local
+summary or partial folder is not the same product and must be described as a
+fallback or adaptation.

+map, not a replacement for the upstream skills.
+
+| Upstream skill | Upstream purpose | Typical trigger | ScholarAIO fallback when upstream is unavailable |
+|----------------|------------------|-----------------|--------------------------------------------------|
+| `nature-figure` | Nature/high-impact Python or R figure workflow with figure contract, export QA, and source-data traceability. | Nature figure, publication plot, scientific figure, figures4papers, manuscript figure. | `/draw` for diagrams/visuals; keep evidence/source-data checks explicit. |
+| `nature-polishing` | Nature-style academic prose polishing, restructuring, and Chinese-to-English manuscript refinement. | Nature style, polish, academic writing, manuscript paragraph, abstract polish. | `/writing-polish`. |
+| `nature-writing` | Nature-style manuscript section drafting and argument restructuring. | Nature writing, write abstract, write introduction, manuscript draft, section reconstruction. | `/paper-writing`. |
+| `nature-reviewer` | Nature-style reviewer assessment with three referee reports and cross-review synthesis. | Nature reviewer, pre-submission review, mock peer review, reviewer report, critique. | Use `/paper-writing` or `/citation-check` only for downstream fixes; if no upstream skill exists, produce a bounded fallback critique and mark it non-equivalent. |
+| `nature-citation` | Strict Nature/CNS-family citation retrieval, claim segmentation, support grading, and ENW/RIS/Zotero RDF export. | Nature citation, CNS citation, supporting references, add citations, reference export. | `/search` + `/citation-check` + `/export`. |
+| `nature-data` | Nature/Springer Nature Data Availability statements, repository plans, dataset citations, FAIR metadata checks. | Data Availability, repository, FAIR metadata, source data, accession number, DOI, code availability. | Use this bridge for gap inventory, then `/paper-writing` or `/writing-polish` only for wording; mark as fallback. |
+| `nature-reader` | Full-paper bilingual Markdown reader with source anchors, figure/table grounding, and no summary-only degradation. | Nature reader, full markdown, paper md, 原文对照, 图文对应, 全文翻译. | `/show` + `/translate`. |
+| `nature-response` | Point-by-point reviewer response letters with comment triage, action mapping, and risk checks. | response to reviewers, rebuttal letter, major revision, 审稿意见回复. | `/review-response`. |
+| `nature-paper2ppt` | Chinese PPTX decks from scientific papers for journal club, group meeting, or academic presentation. | paper PPT, journal club, paper to slides, paper presentation, 组会PPT. | `/show` or `/paper-guided-reading` for evidence, then `/document`. |
+| `nature-academic-search` | Multi-source literature search, citation verification, MeSH strategy, citation-file management, and reference management. | search papers, academic search, literature search, verify DOI, reference management. | `/search`, `/websearch`, `/citation-check`, `/export`. |
+
+## Route Principles
+
+- Prefer the upstream skill when available.
+- Use ScholarAIO fallbacks only when the upstream skill cannot be executed in
+  the current environment.
+- Keep the upstream trigger breadth: this is not submission-only.
+- Submission package is only one scenario; most upstream skills can be invoked
+  for ordinary high-impact academic writing, reading, figures, slides, citation,
+  search, or data work.
