A tool for copying research references from a BibTeX file, a common plain-text bibliography format, into Zotero and Obsidian. Zotero manages citation records, while Obsidian stores linked research notes.

Use it after a literature search or with an existing .bib file to register references, create literature notes, and extract broader concept notes when enough papers are available.

It reduces repeated manual entry and keeps reference records and literature notes aligned. It can also find shared ideas across a growing collection of papers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.06190
Opus 5	$0.00020	$0.03095
Sonnet 5	$0.00008	$0.01238
Haiku 4.5	$0.00004	$0.00619

Measured 3d ago against content hash d41481e90c1b, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

lit-sync scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check_citekey_provenance.py, tests/citekey_provenance_challenge_selftest.sh, tests/citekey_provenance_challenge.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 570 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Literature Sync: Zotero + Obsidian Pipeline

Takes the .bib output of /search-lit (or any user-specified .bib file) and synchronizes the references into the Zotero library and Obsidian literature notes. When enough literature notes accumulate, extracts cross-cutting concept notes.

Communication Rules

Communicate with the user in their preferred language.
Vault layout — honor what exists, default to English. Before creating notes, detect the vault's existing layout: if the vault already uses a particular folder structure (including a Korean one such as 02 연구/문헌/ and 02 연구/개념노트/), honor it — never silently rename a user's folders. For a new or unclear vault, default to the English folders Literature/ and Concepts/ with the English note templates below.
A Korean opt-in variant (Korean folder layout + Korean-heading templates) lives in references/locale/ko/note_templates.md — use it when the vault is Korean-structured or the user prefers Korean notes.

When to Use

After /search-lit completes — sync the produced .bib into Zotero + Obsidian.
Bulk-register references from an existing .bib into Zotero + Obsidian.
Tidy the references/ folder inside a project workspace.
On explicit concept-extraction request → extract cross-cutting concepts from existing literature notes.

Prerequisites

Project owner only — /lit-sync is an owner-scoped operation per docs/zotero_policy.md. Collaborators consume the committed manuscript/_src/refs.bib snapshot read-only.
Zotero desktop 7.x + Better BibTeX plugin installed.
Better BibTeX "Keep updated" auto-export configured to <project>/manuscript/_src/refs.bib (owner setup checklist in docs/zotero_policy.md §Setup).
Zotero MCP server available (skip the Zotero phase if not connected; auto-export refresh still fires once Zotero is reopened).
Obsidian CLI or direct file writing to the Obsidian vault.
Obsidian vault path: configured in user's environment (e.g., $OBSIDIAN_VAULT).

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lit-sync is a skill published in the GitHub repository Aperivue/medsci-skills (290 stars, last pushed 2d ago), licensed MIT. It adds 41 tokens to every session and 6,190 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
