Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00069 | $0.02503 |
| Opus 5.5 | $0.00028 | $0.01001 |
| Sonnet 5.5 | $0.00014 | $0.00501 |
| Haiku 4.5 | $0.00007 | $0.00250 |
Grade A, and why
alphaxiv 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 17d ago.
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.
Use `curl` with `{ALPHAXIV_UA}` to fetch the AlphaXiv overview. AlphaXiv may return 403 for non-browser User-Agents; setting a standard browser UA reduces false positives from bot-detection: This is a copy
91% identical to alphaxiv — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlphaXiv Paper Lookup
Lookup paper: $ARGUMENTS
Quick single-paper reader with tiered source fallback (overview → full markdown → LaTeX source). Powered by AlphaXiv.
Role & Positioning
This skill is the quick single-paper reader that returns LLM-optimized summaries:
| Skill | Source | Best for |
|---|---|---|
/arxiv |
arXiv API | Batch search, PDF download, metadata |
/deepxiv |
DeepXiv SDK | Progressive section-level reading |
/semantic-scholar |
S2 API | Published venue metadata, citation counts |
/alphaxiv |
www.alphaxiv.org | Instant LLM-optimized summary of one paper, with LaTeX source fallback |
Do NOT use this skill for topic discovery, broad literature search, or multi-paper surveys — use /research-lit or /arxiv instead.

What ships with it
1 file 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.
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.

alphaxiv is a skill published in the GitHub repository leecyno1/boutique-skills (5 stars, last pushed 18d ago), licensed MIT. It adds 69 tokens to every session and 2,503 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 91% identical to alphaxiv, differing in 0 lines, and is treated as a copy.
