Use when the codex CLI should be driven from the agent — as a reviewer giving a second, independent opinion ("ask codex", "call codex", "codex review", "get a second opinion", "challenge this finding"), or as an executor doing a scoped task in the repository ("have codex do this", "delegate this to codex", "let codex implement it"). Covers which flags codex actually understands, how much access each mode needs, how to write a prompt that produces verdicts instead of agreement, and the…
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
# Call Codex ## Two modes | | Reviewer | Executor | |---------------------|-------------------------------|------------------------------------------| | Job | break a claim | do a scoped task | | Sandbox | `read-only`, or a throwaway worktree for experiments | `--approve-for-me` plus what the task needs | | The output that matters | the disagreement | the diff | | Verified by | reading the code | reading the diff and running the tests | One binary, one set of traps, two different grants and two different prompts. Picking the wrong grant is the usual failure: a reviewer with write access starts fixing instead of judging, and an executor without network dies on the first dependency fetch. ## Prerequisites Check `which codex`. Report and stop if it is absent. `~/.codex/config.toml` supplies defaults (`model`, `model_reasoning_effort`, `sandbox_mode`, `sandbox_workspace_write.*`, `approvals_reviewer`, `web_search`). Pass everything the run depends …

How to install
mdr add heapy/kortex/call-codex@sha256:683e7a4707b8027eThe line at the top of this page pins the label git:20260925.4cf503a, 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.
