synthetic-sciences/openscience is an AI workbench that carries out scientific research by reading papers, forming hypotheses, writing and running code, conducting experiments, analyzing results, and preparing reports. Researchers use it for work in machine learning, biology, physics, and chemistry with remote or local models. Catalogue add-ons extend its scientific workflows through skills and instructions.
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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00075 | $0.02542 |
| Opus 5 | $0.00037 | $0.01271 |
| Sonnet 5 | $0.00015 | $0.00508 |
| Haiku 4.5 | $0.00007 | $0.00254 |
Grade A, and why
serving-llms-vllm 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 4d 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.

84% identical to serving-llms-vllm — 53 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.

vLLM - High-Performance LLM Serving
Quick start
vLLM achieves 24x higher throughput than standard transformers through PagedAttention (block-based KV cache) and continuous batching (mixing prefill/decode requests).
Installation:
pip install vllm
Basic offline inference:
from vllm import LLM, SamplingParams
llm = LLM(model="meta-llama/Llama-3-8B-Instruct")
sampling = SamplingParams(temperature=0.7, max_tokens=256)
outputs = llm.generate(["Explain quantum computing"], sampling)
print(outputs[0].outputs[0].text)
OpenAI-compatible server:
vllm serve meta-llama/Llama-3-8B-Instruct
# Query with OpenAI SDK
python -c "
from openai import OpenAI
client = OpenAI(base_url='http://localhost:8000/v1', api_key='EMPTY')
print(client.chat.completions.create(
model='meta-llama/Llama-3-8B-Instruct',
messages=[{'role': 'user', 'content': 'Hello!'}]
).choices[0].message.content)
"
Common workflows
Workflow 1: Production API deployment
Copy this checklist and track progress:
Deployment Progress:
- [ ] Step 1: Configure server settings
- [ ] Step 2: Test with limited traffic
- [ ] Step 3: Enable monitoring
- [ ] Step 4: Deploy to production
- [ ] Step 5: Verify performance metrics
Step 1: Configure server settings
Choose configuration based on your model size:
# For 7B-13B models on single GPU
vllm serve meta-llama/Llama-3-8B-Instruct \
--gpu-memory-utilization 0.9 \
--max-model-len 8192 \
--port 8000
# For 30B-70B models with tensor parallelism
vllm serve meta-llama/Llama-2-70b-hf \
--tensor-parallel-size 4 \
--gpu-memory-utilization 0.9 \
--quantization awq \
--port 8000
# For production with caching and metrics
vllm serve meta-llama/Llama-3-8B-Instruct \
--gpu-memory-utilization 0.9 \
--enable-prefix-caching \
--enable-metrics \
--metrics-port 9090 \
--port 8000 \
--host 0.0.0.0
Step 2: Test with limited traffic
Run load test before production:
What ships with it
4 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.
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.

serving-llms-vllm is a skill published in the GitHub repository synthetic-sciences/openscience (3,501 stars, last pushed today), licensed Apache-2.0. It adds 75 tokens to every session and 2,542 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 84% identical to serving-llms-vllm, differing in 53 lines, and is treated as a copy.
