GenLayer Project Boilerplate is a starter codebase for building a GenLayer use case, demonstrated by a football betting game implemented with an intelligent contract. Developers use it to develop and test GenLayer contracts with web access, language-model integration, linting, and a Next.js frontend. The catalogue instruction supports the project's development workflow.
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 | $0.01636 | $0.01636 |
| Opus 5 | $0.00818 | $0.00818 |
| Sonnet 5 | $0.00327 | $0.00327 |
| Haiku 4.5 | $0.00164 | $0.00164 |
Grade A, and why
genlayer-project-boilerplate CLAUDE.md 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 6d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Development Workflow
- Write/modify contract in
contracts/ - Lint:
genvm-lint check contracts/your_contract.py - Test direct:
pytest tests/direct/ -v - Start Studio and deploy:
genlayer deploy - Test integration:
gltest tests/integration/ -v -s - Run frontend:
cd frontend && npm run dev
Contract Development
Contracts are Python files in /contracts/ using the GenLayer SDK:
from genlayer import *
class MyContract(gl.Contract):
data: TreeMap[Address, str]
def __init__(self):
self.data = TreeMap()
@gl.public.view
def get_data(self, addr: Address) -> str:
return self.data.get(addr, "")
@gl.public.write
def set_data(self, value: str):
self.data[gl.message.sender_address] = value
Decorators:
@gl.public.view— Read-only methods@gl.public.write— State-modifying methods@gl.public.write.payable— Methods accepting value
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.

genlayer-project-boilerplate CLAUDE.md is an instructions file published in the GitHub repository genlayerlabs/genlayer-project-boilerplate (17,259 stars, last pushed 1mo ago), licensed MIT. It adds 1,636 tokens to every session, about $0.0082 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.
