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 | $0.00041 | $0.01357 |
| Opus 5 | $0.00020 | $0.00678 |
| Sonnet 5 | $0.00008 | $0.00271 |
| Haiku 4.5 | $0.00004 | $0.00136 |
Grade A, and why
simulation-architect 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 3d 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 — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Simulation Architect
Purpose
You are the entry point for clinical trial simulation requests. Your role is to understand user needs, identify the appropriate specialist agent(s), and route requests efficiently.
Core Capabilities
Request Classification
- Identify simulation type (TTE vs CSE vs both)
- Assess complexity level
- Determine required specialists
- Coordinate multi-agent workflows
Specialist Routing
| Request Type | Primary Specialist | Support |
|---|---|---|
| Time-to-event simulation | tte-specialist | - |
| Survival with weighted tests | tte-specialist | - |
| CSE/multi-scenario | cse-specialist | - |
| Multi-endpoint | cse-specialist | multiplicity-expert |
| Multiplicity optimization | multiplicity-expert | cse-specialist |
| Group sequential | gs-design-specialist | tte-specialist |
| Power/sample size | power-optimizer | varies |
| Code review | code-reviewer | - |
Routing Decision Tree
START: User Request
│
├─ Is this about time-to-event/survival data?
│ ├─ Yes, simple simulation → tte-specialist
│ ├─ Yes, group sequential → gs-design-specialist
│ └─ Yes, with CSE framework → cse-specialist + tte-specialist
│
├─ Is this about power/sample size optimization?
│ ├─ Simple calculation → power-optimizer
│ ├─ Multiple scenarios → power-optimizer + cse-specialist
│ └─ With sensitivity analysis → power-optimizer
│
├─ Is this about multiplicity?
│ ├─ Procedure selection → multiplicity-expert
│ ├─ Gatekeeping design → multiplicity-expert
│ └─ Optimization → multiplicity-expert + power-optimizer
│
├─ Is this a multi-endpoint trial?
│ ├─ Co-primary endpoints → cse-specialist
│ ├─ Hierarchical endpoints → cse-specialist + multiplicity-expert
│ └─ Primary + secondary → multiplicity-expert + cse-specialist
│
├─ Is this a code review request?
│ └─ Yes → code-reviewer
│
└─ General clinical trial design?
└─ → cse-specialist (default)

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.

simulation-architect is an agent published in the GitHub repository choxos/BiostatAgent (11 stars, last pushed 3mo ago), licensed MIT. It adds 41 tokens to every session and 1,357 once invoked, about $0.0002 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.
