Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00024 | $0.01352 |
| Opus 5 | $0.00012 | $0.00676 |
| Sonnet 5 | $0.00005 | $0.00270 |
| Haiku 4.5 | $0.00002 | $0.00135 |
Grade B, and why
biorxiv-search scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
BIORXIV_SCRIPT=$(find ~/.claude/plugins/cache -name "search" -path "*/biorxiv-search/*/scripts/*" -type f 2>/dev/null | head -1) This is a copy
100% identical to biorxiv-search — 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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
bioRxiv Search
Search the complete bioRxiv database of biological sciences preprints using natural language queries powered by Valyu's semantic search API.
Why This Skill is Powerful
- No API Parameter Parsing: Just pass natural language queries directly - no need to construct complex search parameters
- Semantic Search: Understands the meaning of your query, not just keyword matching
- Full-Text Access: Returns complete article content, not just abstracts
- Image Links: Includes figures and images from papers
- Comprehensive Coverage: Access to all bioRxiv preprints in biological sciences
Requirements
- Node.js 18+ (uses built-in fetch)
- Valyu API key from https://platform.valyu.ai ($10 free credits)
CRITICAL: Script Path Resolution
The scripts/search commands in this documentation are relative to this skill's installation directory.
Before running any command, locate the script using:
BIORXIV_SCRIPT=$(find ~/.claude/plugins/cache -name "search" -path "*/biorxiv-search/*/scripts/*" -type f 2>/dev/null | head -1)
Then use the full path for all commands:
$BIORXIV_SCRIPT "CRISPR gene editing" 15
API Key Setup Flow
When you run a search and receive "setup_required": true, follow this flow:
-
Ask the user for their API key: "To search bioRxiv, I need your Valyu API key. Get one free ($10 credits) at https://platform.valyu.ai"
-
Once the user provides the key, run:
scripts/search setup <api-key> -
Retry the original search.
Example Flow:
User: Search bioRxiv for CRISPR advances
→ Response: {"success": false, "setup_required": true, ...}
→ Claude asks: "Please provide your Valyu API key from https://platform.valyu.ai"
→ User: "val_abc123..."
→ Claude runs: scripts/search setup val_abc123...
→ Response: {"success": true, "type": "setup", ...}
→ Claude retries: scripts/search "CRISPR advances" 10
→ Success!
When to Use This Skill
- Finding biology research not yet published in journals
- Cross-disciplinary life sciences research
- Rapid access to unpublished experimental data
- Disease mechanism research
- Evolutionary and developmental biology studies
- Ecological research and conservation biology
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.
- 11d ago First seen · 224 lines · 24 tokens per session scan B f084204761ba
biorxiv-search is a skill published in the GitHub repository Zaoqu-Liu/ScienceClaw (60 stars, last pushed 5mo ago), licensed MIT. It adds 24 tokens to every session and 1,352 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). It is 100% identical to biorxiv-search, differing in 0 lines, and is treated as a copy.
