icl-runtime 0.1.3

Python bindings for ICL (Intent Contract Language) — deterministic intent contracts

ICL Python Bindings

Python bindings for the ICL (Intent Contract Language) runtime.

Built with PyO3 + maturin — thin wrapper around the canonical Rust implementation.

Status: Alpha

This package is in early development. The API may change.

Install

pip install icl-runtime

Published on PyPI.

Or build from source (requires Rust toolchain):

pip install maturin
cd bindings/python
maturin develop

Usage

import icl
import json

contract_text = open("my-contract.icl").read()

# Parse
parsed = json.loads(icl.parse_contract(contract_text))

# Normalize (deterministic canonical form)
normalized = icl.normalize(contract_text)

# Verify (type checking, invariants, determinism)
result = json.loads(icl.verify(contract_text))
if result["valid"]:
    print("Contract is valid!")

# Execute
output = json.loads(icl.execute(contract_text, '{"operation": "greet", "inputs": {"name": "World"}}'))

# Semantic hash (SHA-256)
hash_hex = icl.semantic_hash(contract_text)

Guarantees

• Deterministic: Same input always produces identical output
• Identical to Rust: All results match the canonical Rust implementation exactly
• Zero logic in bindings: All behavior comes from icl-core
