| ARXIVSUB_SKILL_KEY | Yes | Your API key from arXivSub Skills page (get a free 7-day trial at https://arxivsub.comfyai.app/skills) |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_papersA | Search academic papers from arXiv and major AI/CV/ML/robotics/NLP conferences via arXivSub (semantic + keyword search over a structured, summarized corpus). Use for 'find papers on X', 'latest research about Y', 'recent conference work on Z', or to start a literature review. Returns each paper with a 6-part summary (what it's about, innovations, techniques, datasets, results, limitations), authors + affiliations, pdf_url, and github_url when code is available. |
| find_similar_papersA | Given ONE paper you already have (from a prior search result), return the most similar papers from the same corpus — semantic nearest neighbours, each with the full summary and code link. Use for 'more like this', 'related work', 'what else is in this line of work', or to expand a literature review. You can chain it: search -> pick a seed -> find_similar_papers -> repeat on a strong neighbour. |
| research_insightA | Build aggregate pivot statistics over the arXivSub corpora — the same engine as the website's Custom Chart. Use for trends, rankings, breakdowns and comparisons: 'how has interest in diffusion models trended', 'top institutions in RL', 'papers per month by keyword', 'avg citations by affiliation'. Returns rows of {dim, breakdown, value} for you to interpret and visualize. Requires Pro or active trial days. |
| library_saveA | Save (or update) a paper in the user's personal arXivSub library. Use for 'save this', 'bookmark that paper', 'add it to my collection', 'note that ...', 'mark as read'. Idempotent: saving the same paper again updates only the fields you pass and never duplicates. Cannot delete — removals are done on the website. |
| library_listA | List the user's personal arXivSub library — collections and saved items, optionally filtered. Use for 'what have I saved', 'show my library', 'which papers are in my collection', 'what am I reading'. |

Scored across 5 tools
Each tool targets a distinct function: search_papers for query-based discovery, find_similar_papers for similarity expansion, research_insight for aggregate analytics, and library_save/library_list for personal library management. There is no ambiguity between them.
Most tools follow a verb_noun pattern (search_papers, find_similar_papers), but library_save and library_list invert this to noun_verb, and research_insight is ambiguous. The underscore-separated lowercase style is consistent, but the word order is not uniform.
At 5 tools, the set is well-scoped for the server's purpose: search, similar, analytics, and library operations. Each tool earns its place without redundancy or bloat.
The surface covers core workflows (search, similar, trends, save, list), but library_delete is explicitly absent, forcing removals to be handled externally. A direct get-by-ID tool is also missing, though search can compensate. Minor gaps that agents can work around.
