Install
codex is not found, the CLI version is unexpected, or PATH and install location are unclear.
MIT-licensed read-only diagnostic collector
Codex Safe Check
A small collector for Codex CLI install, login, proxy, custom CA, CODEX_HOME, and connectivity problems. It reports versions and presence signals without reading secrets, auth files, source code, logs, usernames, hostnames, working directories, or proxy addresses.
Use It When
Login
Browser login does not return to the CLI, or a remote, WSL2, SSH, or headless environment needs a safer first check.
Network
Proxy, custom CA, TLS interception, sandboxed networking, or official endpoint reachability may be involved.
Boundary
Do not paste passwords, one-time codes, API keys, access tokens,
auth.json, full logs, source code, full config files, identity documents, or screenshots containing account details into public issues.
Paid Diagnosis
The collector is free. The paid offer is a written diagnosis from a manually reviewed, redacted report, with prioritized fix steps and one follow-up. The payment link will be added after the creator/payment account is published. Until then, do not send diagnostic reports through GitHub issues.
Read a sample diagnosis report to see the expected format before the paid link is live.
Follow the public paid diagnosis status thread or use the safe interest form for launch notification. Do not post diagnostic reports, secrets, or payment details there.
