codex-local-cli-e2e

A test workflow for checking Agmente’s iOS connection to a real local Codex app-server, which is the program that provides Codex sessions over a network connection.

In plain words
What is it for?
Use it to verify WebSocket connections, startup handshakes, thread creation, and session flows with a simulator and local Codex server.
Why use it?
It isolates Codex connection and session-flow failures and records useful details when the test fails.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

codex-local-cli-e2e 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run_codex_local_e2e.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Codex Local CLI E2E

Overview

Run Agmente's Codex UI E2E test against a real local codex app-server, using the repo-owned scenario spec as the source of truth, collect actionable failure details, and always clean up simulator/app-server state.

Workflow

  1. Resolve run inputs.
  • Require endpoint (for example ws://127.0.0.1:8788) and simulator UDID.
  • Decide run mode:
    • existing server: server already running.
    • managed server: start server with a provided command and stop it during cleanup.
  • Read e2e/scenarios/codex/local-cli-smoke.md.
  • Use references/agmente-codex-e2e-contract.md only for the UI-test environment-variable harness contract.
  1. Start or verify server.
  • If managed server, start the command and wait until the endpoint port is reachable.
  • If existing server, verify reachability before running tests.
  1. Run only the Codex UI E2E test.
  • Export:
    • AGMENTE_E2E_CODEX_ENABLED=1
    • AGMENTE_E2E_CODEX_ENDPOINT=<endpoint>
  • Execute targeted test only:
    • AgmenteUITests/AgmenteUITests/testCodexDirectWebSocketConnectInitializeAndSessionFlow
  1. On failure, extract root cause.
  • Parse xcodebuild output for the failing test and assertion.
  • Read .xcresult details when xcodebuild is not explicit.
  • Include failing file/line and endpoint/simulator context in the report.
  1. Always clean up.
  • Stop app-server if this run started it.
  • Uninstall app from simulator:
    • xcrun simctl uninstall <UDID> com.example.Agmente
  • Optionally shut simulator down if requested.

Preferred Execution

Use the bundled script for deterministic runs:

  • scripts/run_codex_local_e2e.sh

Managed-server example:

scripts/run_codex_local_e2e.sh \
  --endpoint ws://127.0.0.1:8788 \
  --udid <SIMULATOR_UDID> \
  --start-codex-cmd "codex app-server --listen ws://127.0.0.1:8788"

Existing-server example:

scripts/run_codex_local_e2e.sh \
  --endpoint ws://127.0.0.1:8788 \
  --udid <SIMULATOR_UDID>

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
