Validate function calling schemas and tool parameter types for LLMs

When to use it. When requiring verified Developer Workflow functionality in autonomous workflows

Readme

genesis-tool-contract-lint

Deterministic schema linter for LLM function calling and tool declarations.

Version License: MIT Zero Dependencies


The Problem

When developers create function-calling schemas for OpenAI, Anthropic, or Gemini, subtle mistakes cause runtime failures:

  • Function names contain forbidden characters (spaces, special punctuation).
  • Descriptions are empty or terse, leading LLMs to call the wrong tools.
  • Property types use unsupported JSON types.
  • Fields listed under required are missing from the properties map.

The Solution

genesis-tool-contract-lint deterministically lints tool declarations against official LLM provider specifications before deployment, ensuring flawless function calling.


Key Features

  • Zero Third-Party Dependencies: Pure Python 3 standard library.
  • Provider Conformance: Checks OpenAI, Anthropic, and Gemini function declaration formats.
  • Schema Validation: Checks parameter object structures, property types, and required field definitions.
  • CI / Pre-commit Gate: Returns exit code 1 if any schema errors are detected.

Quickstart

# Clone the repository
git clone git@github.com:genesiscode2026/genesis-tool-contract-lint.git
cd genesis-tool-contract-lint

# Lint a tools declaration file
./bin/genesis-tool-lint ./tools.json

# Pipe from stdin or another process
cat tools.json | ./bin/genesis-tool-lint -

# Output machine-readable JSON
./bin/genesis-tool-lint ./tools.json --json

The resource endpoint answers 402 with the price and the exact bytes to sign; the same request carrying PAYMENT-SIGNATURE returns a signed download URL. Access is granted only after settlement returns a transaction hash. A person can do the same thing with a browser wallet on the product page.

# the 402, with the price and the exact bytes to sign
curl -si https://x402git.com/api/r/genesiscode2026/genesis-tool-contract-lint

# what your wallet already owns, and what the next fetch would cost it
curl -s https://x402git.com/api/v/genesiscode2026/genesis-tool-contract-lint \
  -H "X-Wallet-Signature: 0xYOURADDRESS.<nonce>.<signature>"
