Manage Refs

Manage-Refs Skill

You are routing reference-handling work for a medical manuscript. The user is somewhere in the lifecycle — drafting, building a circulation DOCX, swapping CSL after a journal rejection, fixing a cross-reference defect surfaced by QC, or wiring up live Zotero field codes for a co-author Word workflow. Pick the right tool from the decision table; do not invent a parallel pipeline.

Why This Skill Exists

Reference handling spans every late-stage skill: /write-paper builds the first DOCX, /revise rebuilds it after each reviewer round, /peer-review emits a critique that quotes references back, /sync-submission packages the final tarball, /find-journal informs CSL swaps on rejection cascade, and /verify-refs audits the bibliography. Until 2026-05-01 these scripts lived under skills/write-paper/scripts/, which made /revise and /sync-submission silently depend on a sibling skill — a layering inversion that broke when /write-paper was loaded into a non-research project. Moving the lifecycle tools here turns reference handling into a first-class concern with one decision tree, one set of CSL files, and one provenance file (NOTICE.md) for the vendored Zotero CWYW writer.

Validated 2026-05-01 against a 21-reference meta-analysis manuscript (a meta-analysis project's submission) for both pandoc-citeproc and Zotero-CWYW paths.

Anti-Hallucination Guarantees

1. Citekey discipline (Phase 0): every in-text citation must be [@bibkey] resolvable in refs.bib. scripts/check_citation_keys.py is a hard gate — UNDEFINED keys exit non-zero and block the build.

   [@NEW:topic] placeholder convention: while drafting, /write-paper may emit [@NEW:topic_slug] markers for citations the author still needs to source. check_citation_keys.py classifies these as NEW_PLACEHOLDER (not UNDEFINED) and exits 0 — the build is allowed to proceed during drafting. Phase 7.6 (DOCX render) is a hard gate: zero NEW_PLACEHOLDER entries must remain. Resolve each by adding the citation to Zotero (then /lit-sync refreshes refs.bib) and replacing the placeholder with the real [@bibkey]. Never let a [@NEW:...] reach a rendered DOCX.

2. No hand-typed References list — references are always rendered by pandoc citeproc + journal CSL or by the Zotero Word plugin (CWYW). See ~/.claude/rules/manuscript-references.md.

3. Zotero metadata is never invented — inject_zotero_cwyw.py fetches item data live from http://localhost:23119. Any HTTP failure aborts with a non-zero exit so partial bibliographies never reach the user.

4. Marker conversion is mapping-driven — md_marker_convert.py will never guess a Zotero key for a number; unmapped markers stay as [N] and are reported on stderr.

5. Cross-reference QC is a submission gate — scripts/check_xref.py --strict exits 1 on any MISSING_DOCX / MISSING_BODY / MISMATCH, blocking pipelines that try to ship a DOCX whose Table/Figure citations don't match captions.

6. Audit boundary: this skill writes; bibliographic correctness against PubMed/CrossRef stays in /verify-refs. Always invoke /verify-refs after a render before signing off — one read-only audit, one writer.

Decision Tree

Workflows

A. Pandoc citeproc (default for solo authors and final submissions)

User provides manuscript.md with [@bibkey] citations + refs.bib.

1. Gate: python "${CLAUDE_SKILL_DIR}/scripts/check_citation_keys.py" manuscript.md refs.bib — exits non-zero on UNDEFINED keys. Fix and re-run.
2. Render:

   "${CLAUDE_SKILL_DIR}/scripts/render_pandoc.sh" \
     -j european-radiology \
     -i manuscript.md \
     -b refs.bib \
     -o manuscript_final.docx
   

   Bundled CSLs (in citation_styles/): european-radiology, radiology, american-journal-of-roentgenology, cardiovascular-and-interventional-radiology, korean-journal-of-radiology, vancouver, vancouver-superscript, springer-basic-brackets, springer-vancouver-brackets. Use radiology for RYAI; use vancouver for JVIR (no dedicated CSL).
3. QC:

   python3 "${CLAUDE_SKILL_DIR}/scripts/check_xref.py" \
     --md manuscript.md --docx manuscript_final.docx \
     --out qc/xref_audit.json --strict
   

   Treat submission_safe: false as a halt. Route fixes by symptom — see the table in references/check_xref_symptoms.md.
4. Audit hand-off: invoke /verify-refs for the PubMed/CrossRef audit before sign-off.

B. Zotero CWYW (co-author Word workflow)

User has a markdown SSOT and wants reviewers to edit citations directly in Word. Each reference must already exist as a Zotero item; the user supplies a [N] → ZoteroKey mapping.

1. Convert markers:

   python3 "${CLAUDE_SKILL_DIR}/scripts/md_marker_convert.py" \
     --input manuscript.md --output manuscript_keys.md \
     --map ref_map.json --to-keys
   

   Optionally stage with --active-ns 1,2,3,4,19 for a sample build first (validated on an active meta-analysis project: 5-ref sample reduces Word Refresh blast radius when debugging).
2. Render to .docx with pandoc (workflow A) so the body has plain text [@key] markers, OR pre-build a .docx some other way that still contains plain [@key] text.
3. Inject CWYW:

   python3 "${CLAUDE_SKILL_DIR}/scripts/inject_zotero_cwyw.py" \
     --input manuscript_keys.docx --output manuscript_cwyw.docx \
     --user-id 16613550 --keys-from keys.txt
   

   The script fetches Zotero metadata via the local connector (port 23119); any HTTP failure aborts with non-zero exit.
4. First-build instruction (REQUIRED — see Known Limitation #1): open the output in Word → Zotero tab → Add/Edit Bibliography once. After that, Refresh keeps citations and bibliography in sync as authors edit.
5. Surgical patches are unsafe: for ref additions in later rounds, edit the markdown SSOT and rebuild the whole .docx instead of regex-patching the post-CWYW file. Zotero's rendered [N] superscripts can collide with plain [N] markers and corrupt the field codes.

C. Cascade rejection re-render (find-journal hand-off)

User got rejected from journal A and /find-journal recommended journal B.

1. Confirm the new CSL exists in citation_styles/ (or fetch from https://citationstyles.org/styles and drop in).
2. Re-run render_pandoc.sh -j <new-csl> against the same manuscript.md + refs.bib.
3. Re-run check_xref.py --strict.
4. Re-run /verify-refs if any new references were added during the inter-journal revision.

D. Cross-reference QC only

User shipped a manuscript and a reviewer flagged a Table/Figure mismatch.

1. Run check_xref.py --strict on the current manuscript.md + .docx.
2. Inspect qc/xref_audit.json. Body caption is the SSOT — fix manuscript.md and rebuild, never patch the .docx by hand.
3. See references/check_xref_symptoms.md for the MISSING_BODY / MISSING_DOCX / MISMATCH triage table.

Quality Gates

This skill defines three submission gates and one user approval gate:

• Gate 1 (citekey integrity): check_citation_keys.py exits non-zero on UNDEFINED keys. The pipeline halts; the user reviews and fixes.
• Gate 2 (cross-reference integrity): check_xref.py --strict exits 1 on any MISSING_DOCX / MISSING_BODY / MISMATCH row. The user reviews qc/xref_audit.json and resolves before proceeding.
• Gate 3 (audit hand-off): before sign-off, the user must run /verify-refs and confirm submission_safe: true in qc/reference_audit.json. This skill never marks the bibliography audited on its own.
• User approval gate (CWYW first build): the user must perform Word → Zotero → Add/Edit Bibliography manually after the first inject_zotero_cwyw.py build. The skill cannot automate this and warns on stderr that it is required.

Known Limitations

1. First-build empty BIBL field (CWYW): inject_zotero_cwyw.py writes a stub ADDIN ZOTERO_BIBL field; Word's Zotero Refresh treats an empty stub as user-customized and refuses to populate it. User must run Add/Edit Bibliography once. Subsequent Refresh works as expected. Validated on Word for Mac, an active meta-analysis project.
2. Webpage / non-journal item types: handled by the patched zotero_to_csl_json that fetches Zotero's native CSL-JSON; do not bypass this patch.
3. Surgical post-build regex patches are unsafe — see Workflow B step 5.
4. Local Zotero required for CWYW — port 23119 must be reachable; no web-API fallback yet (would need ZOTERO_API_KEY). On failure the script aborts with non-zero exit so partial builds never ship.
