search

A command-line toolkit for finding academic papers, following their citations, downloading available papers, extracting figures, reading LaTeX sources, and fetching BibTeX references. It also supports general web search and browser automation.

In plain words
What is it for?
Use it to search sources such as arXiv, OpenAlex, and Crossref; retrieve papers and figures; inspect LaTeX; create citations; and fetch web pages.
Why use it?
It brings several research tasks into one workflow instead of requiring separate searches, downloads, citation lookups, and browser tools.

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.

Security

Grade A, and why

search scanned grade A with 0 findings 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/setup.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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

Search Skill

All information gathering in one place. Two CLI tools:

  • scripts/search — paper search, citations, download, LaTeX source, BibTeX, web search, URL fetch
  • scripts/browse — browser automation wrapper (uses browser-use with headed + Chrome profile defaults)

Setup

bash scripts/setup.sh

Paper Search

scripts/search papers "Rydberg atom quantum gate"
scripts/search papers "topological insulators" --source openalex --count 20
scripts/search papers "diffusion models" --source arxiv --count 15
scripts/search papers "air pollution health effects" --source crossref --count 20
scripts/search papers "quantum error correction" --from-year 2024 --sort date --count 20
# Author-filtered search: use last name as an indexed field, not free text.
# At least one of <query> or --author is required; both together = AND.
scripts/search papers "" --author "Lukin" --from-year 2025 --sort date --count 20
scripts/search papers "neutral atom arrays" --author "Bluvstein" --count 15
  • OpenAlex: all fields, citation counts, DOIs. --source openalex
  • arXiv: recent preprints, physics/CS/math. --source arxiv
  • CrossRef: broadest coverage (120M+ records), all disciplines, non-English journals. --source crossref
  • Default: all three.
  • --author <LastName>: Filter by author last name. Maps to arXiv au:, OpenAlex raw_author_name.search, and CrossRef query.author — all indexed fields. Strongly preferred over putting the name in the free-text query, which treats the name as an unweighted keyword and routinely misses the target. Pair with --from-year for recent work by a specific researcher.
  • --from-year YYYY: Only return papers published in YYYY or later.
  • --sort relevance|date: Sort by relevance (default) or publication date (newest first).

Files

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.

search is a skill published in the GitHub repository Muuuun/luxas (899 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 2,363 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
