Disable LLM gateway for Codex engine by Copilot · Pull Request #15748 · github/gh-aw

Copilot · 2026-02-14T19:00:55Z

The Codex engine no longer requires LLM gateway proxying for API requests. Updated SupportsLLMGateway() to return -1, signaling no gateway support.

Changes

pkg/workflow/codex_engine.go: Changed SupportsLLMGateway() return value from constants.CodexLLMGatewayPort (10001) to -1
Test updates: Updated 4 test files to reflect that Codex no longer:
- Includes API proxy Docker images in collected images
- Adds --enable-api-proxy flag to AWF commands
- Gets special treatment in strict mode validation (now treated like Copilot)
Workflow recompilation: Recompiled 10 Codex workflow lock files to reflect the LLM gateway changes:
- Removed api-proxy Docker image from download steps
- Removed --enable-api-proxy flag from AWF commands

Example

// Before
func (e *CodexEngine) SupportsLLMGateway() int {
    return constants.CodexLLMGatewayPort
}

// After  
func (e *CodexEngine) SupportsLLMGateway() int {
    return -1
}

The convention is: positive port numbers indicate LLM gateway support, -1 indicates no support. This change aligns Codex with Copilot and Custom engines, which also return -1.

Affected Workflows

The following Codex workflows were recompiled with the updated engine behavior:

changeset.lock.yml
codex-github-remote-mcp-test.lock.yml
daily-fact.lock.yml
daily-issues-report.lock.yml
daily-observability-report.lock.yml
daily-performance-summary.lock.yml
deep-report.lock.yml
duplicate-code-detector.lock.yml
issue-arborist.lock.yml
smoke-codex.lock.yml

✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.

Changeset

Type: patch
Description: Disable the Codex LLM gateway proxy and update related workflows/tests to match the simplified engine behavior.
