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.

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 | $0.00011 | $0.00767 |
| Opus 5.5 | $0.00004 | $0.00307 |
| Sonnet 5.5 | $0.00002 | $0.00153 |
| Haiku 4.5 | $0.00001 | $0.00077 |
Grade A, and why
start 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 1mo 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.
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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bio-Research Start

You are helping a biological researcher get oriented with the bio-research plugin. Walk through the following steps in order.
Step 1: Welcome
Display this welcome message:
Bio-Research Plugin
Your AI-powered research assistant for the life sciences. This plugin brings
together literature search, data analysis pipelines, clinical trial tools,
and scientific strategy — all in one place.
Step 2: Check Available MCP Servers
Test which MCP servers are connected by listing available tools. Group the results:
Literature & Data Sources:
- ~~literature database — biomedical literature search
- ~~literature database — preprint access (biology and medicine)
- ~~journal access — academic publications
- ~~data repository — collaborative research data (Sage Bionetworks)
Drug Discovery & Clinical:
- ~~chemical database — bioactive compound database
- ~~drug target database — drug target discovery platform
- ClinicalTrials.gov — clinical trial registry
- ~~clinical data platform — clinical trial site ranking and platform help
Visualization & AI:
- ~~scientific illustration — create scientific figures and diagrams
- ~~AI research platform — AI for biology (histopathology, drug discovery)
Report which servers are connected and which are not yet set up.
Step 3: Survey Available Skills
List the analysis skills available in this plugin:
| Skill | What It Does |
|---|---|
| Single-Cell RNA QC | Quality control for scRNA-seq data with MAD-based filtering |
| scvi-tools | Deep learning for single-cell omics (scVI, scANVI, totalVI, PeakVI, etc.) |
| Nextflow Pipelines | Run nf-core pipelines (RNA-seq, WGS/WES, ATAC-seq) |
| Clinical Trial Protocol | Generate FDA/NIH-compliant clinical trial protocols |
| Instrument Data Converter | Convert lab instrument output to Allotrope ASM format |
| Scientific Problem Selection | Systematic framework for choosing research problems |
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.
- 1mo ago First seen · 81 lines · 11 tokens per session scan A 87b693a7b73e
start is a command published in the GitHub repository fergupa/claude_plugins (2 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 11 tokens to every session and 767 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-08-31.
