codex skillA
codex is agent-read markdown (skill) from notque/vexjoy-agent: Run benchmark-selected GPT-5.6 work through the Codex CLI..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# Codex — the GPT-5.6 Execution Lane Run a benchmark-selected GPT-5.6 task through the Codex CLI (`codex exec`) and return the result. This is the OpenAI execution lane — the general-purpose lane for work the model-selection policy sends to GPT-5.6, and the **canonical owner of general `codex exec` mechanics** — when the CLI changes, update here first. GPT selections are reachable only through this CLI; the Agent tool's `model` parameter covers Claude models only. **Under Claude Code, this skill runs only on explicit invocation or cross-provider escalation, never as the automatic default.** The harness-native model lane under Claude Code is the Anthropic lane (Opus 5). This skill is a deliberate cross-provider tool — codex review as a second-opinion, codex exec for a GPT-specific constraint — not a routing default. Two flows keep their own specialized codex integration — route to them instead of re-implementing here: | Existing flow | Owns | Where | |---|---|---| ## Phase 1: DECIDE — does this task belong on GPT-5.6? …

How to install
mdr add notque/vexjoy-agent/codex@git:20260922.5ea2099mdr add notque/vexjoy-agent/codex@sha256:fb29220fdcc0d2c6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
