# Code Review: Step 1 — Discover current server and Codex CLI behavior

## Verdict

Approved. No blocking findings.

## Findings

None.

## Verification performed

- Reviewed the diff from `ba134468d8d839c806197bebc46d0191355c6563..HEAD`.
- Read `PROMPT.md` and the updated `STATUS.md`.
- Re-ran `make build`; it completed successfully and rebuilt `bin/icuvisor`.
- Inspected Codex help for `codex --help`, `codex exec --help`, `codex mcp --help`, and `codex mcp add/get/list --help`.
- Confirmed the documented binary path exists and is a Mach-O arm64 executable.
- Sanity-checked Codex `-c mcp_servers.icuvisor.*` overrides with an isolated `CODEX_HOME`; Codex recognizes `command`, `cwd`, and `env_vars` in the listed stdio transport.

## Non-blocking notes

- The plan correctly avoids `codex mcp add` against the default user config and defers `.env` access to Step 2.
- For Step 2/3, keep using normal Codex auth with `--ignore-user-config` unless a temporary `CODEX_HOME` is explicitly proven to have working auth. A temporary `CODEX_HOME` is useful for non-mutating discovery, but it can otherwise isolate Codex from existing credentials.
