15 days oldThe repository was created 15 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
24 stars24 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Stage 5 of the lit review pipeline: merge and deduplicate papers from all prior stages (Undermind, Scholar Labs, supplementary search) into a single master list with provenance tracking. Two-pass dedup: exact DOI match then LLM fuzzy match via DeepSeek/Claude. Only use this skill when explicitly requested — e.g., the user says "run lit-dedup", "lit-dedup", or "/lit-dedup". Do NOT auto-trigger on general literature review requests.

Lit-Dedup (Stage 5 — Merge & Deduplicate)

Merge multiple pipeline stage outputs into one deduplicated master list with provenance tracking.

Input: one or more JSON files from Stages 1–4 Output: merged_results.json + merged_results.ris + dedup_log.json

Quick Start

# Merge all JSON files in a directory
python scripts/lit_dedup.py --input-dir ./results/ -o merged_results.json

# Merge specific files
python scripts/lit_dedup.py --inputs stage1.json stage2.json stage4.json -o merged.json

# DOI-only dedup (skip LLM pass)
python scripts/lit_dedup.py --inputs *.json --no-llm -o merged.json

# Non-interactive (skip confirmation)
python scripts/lit_dedup.py --inputs *.json -o merged.json --yes

Prerequisites

pip install aiohttp

API Keys

DEEPSEEK_API_KEY — primary (DeepSeek chat API for fuzzy matching)
ANTHROPIC_API_KEY — fallback (Claude Sonnet via Anthropic API)

CLI Flags

Flag	Default	Description
`--inputs`	—	Input JSON files (nargs='+')
`--input-dir`	—	Directory to glob *.json from
`-o, --output`	`merged_results.json`	Output JSON path
`--model`	`deepseek-chat`	LLM model override
`--concurrency`	`100`	Max simultaneous LLM requests
`--no-llm`	off	Skip Pass 2 (DOI-only dedup)
`--yes`	off	Skip HITL confirmation checkpoint
`--emit-pairs PATH`	—	Agent-driven: write candidate pairs to PATH and stop before the LLM pass (no API)
`--ingest-verdicts EMIT VERDICTS`	—	Agent-driven: merge the subagent pair verdicts and write all outputs (no API)

Two-Pass Dedup

Pass 1 — DOI match: normalize DOIs, group by exact match, merge using priority (published > forthcoming > working paper)
Pass 2 — LLM fuzzy match: pre-filter candidate pairs by author surname overlap or title Jaccard > 0.4, then judge each pair for a same-paper verdict

Model routing (agent-driven default)

In the orchestrator's agent-driven flow the Pass-2 same-paper judgment is made by a subagent, not the API — a Sonnet subagent by default, promoted to Opus when the GUI's Use Opus for all tasks (all_opus) is set. Run --emit-pairs to dump the candidate pairs, judge each {i, j, a, b} pair with the subagent (yes/no duplicate), then --ingest-verdicts to run the union-find merge and write every output. The DeepSeek/Sonnet API path is the autonomous fallback for standalone runs. See the orchestrator SKILL.md ("How it runs" → "Model routing").

Output Schema

Same as pipeline stages, with added fields:

{
  "title": "Paper Title",
  "authors": "Author1, Author2",
  "year": "2024",
  "doi": "10.1234/...",
  "abstract": "...",
  "journal": "Journal Name",
  "url": "https://...",
  "sources": ["undermind", "scholarlabs", "ssrn"],
  "alt_url": "https://ssrn.com/..."
}

Output Files

merged_results.json — deduplicated master list
merged_results.ris — RIS for Zotero import
dedup_log.json — log of all merge decisions and stats
