Install and run OpenAI Codex CLI inside the Minis/iSH Alpine sandbox on iOS, where rustls TLS and async sockets are broken. Covers the local MITM proxy with P-256 certs, version-spoofing to unlock newer models (gpt-5.6 family), forcing SSE instead of websockets, ChatGPT device-auth login driven by curl, and the refcounted proxy wrapper. Use when the user wants Codex or other Rust-based AI CLIs on the iPhone/iPad Minis shell, or hits "error sending request", "must support ECDSA_NISTP521_SHA512…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex on iSH (Minis iOS sandbox) Run the OpenAI Codex CLI natively in the Alpine/iSH environment. Works around the platform's broken Rust networking stack with a local MITM proxy. ## Why this is needed (the two bugs) 1. **rustls misbehaves on iSH's translated CPU.** Official musl binaries ≥ v0.143 panic at the first TLS handshake (`installed rustls crypto provider must support ECDSA_NISTP521_SHA512`) because aws-lc-rs CPU detection fails in the emulator. v0.130 (ring provider) handshakes, but ONLY with ECDSA P-256 certificates — RSA and P-521 get refused. 2. **Async sockets to remote hosts fail** (`connect errno 65` / reqwest `error sending request`). Blocking-socket clients (curl, Python) work fine; loopback connections work fine. Routing Rust traffic through a local proxy converts the hostile leg into a reliable one. Both bugs are iSH-specific. Termux forks do NOT fix them (verified: their rustls code is identical to upstream). ## Install ``` sh scripts/setup.sh ``` This downloads codex v0.130.0 musl aarch64, generates the P-256 CA/server certs, installs `pyproxy6.py` (proxy) and the `codex` wrapper into /usr/local/bin, and …

How to install
mdr add openminis/minisskills/codex-on-ish@sha256:b00686d69c4c54d5The line at the top of this page pins the label git:20260904.47b3917, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
