OpenAI + Zod v4 Compatibility Test

Verifies that @composio/core works correctly with openai and zod@4.

Background

Issue #2336 reported peer dependency conflicts for users with zod@4.

What It Tests

Test	Description
npm install	Installs `@composio/core`, `openai`, and `zod@4`
Package integration	Verifies all packages work together without conflicts
wrapTool	Confirms OpenAI provider tool wrapping works

Fixture

fixtures/
├── index.mjs      # Test script that imports and uses all packages
└── package.json   # Declares dependencies: @composio/core, openai@^6.16.0, zod@^4.3.5

The fixture uses usesFixtures: true with a setup phase to install dependencies at runtime:

package.json declares @composio/core (linked from monorepo), openai, and zod@4
index.mjs imports all three packages and verifies they work together
Tests wrapTool to ensure schema conversion works with Zod v4

Setup

The setup phase runs npm install --legacy-peer-deps in a Docker volume, then the fixture runs with the installed node_modules mounted read-only.

Isolation Tool

Docker with Node.js versions: 20.19.0, 22.12.0.

Running

bash

pnpm test:e2e
