Delegate a task to Codex as a subagent.
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
The user invoked this skill explicitly, which authorizes running Codex with full access for this task.
default_model: !`codex debug models | jq -r '[.models[].slug | select(test("^gpt-[0-9]+(\\.[0-9]+)?-sol$"))] | first' || echo gpt-6.1-sol`
default_effort: high
default_service_tier: default
If the arguments start with a model slug, an effort level, or a service tier (`default` or `fast`), use them; the rest is the task. Otherwise use `default_model`, `default_effort`, and `default_service_tier`.
1. Write a self-contained prompt for the task to a new file in the scratchpad. For computer use, include the keyword `computer_use` in the prompt.
2. Run Codex as one command, with no variable assignments or `&&` before it, using literal paths:
codex -m <model> -c model_reasoning_effort="<effort>" -c service_tier="<service_tier>" --dangerously-bypass-approvals-and-sandbox exec - < <prompt-file> > <log-file> 2>&1
3. Run it in the background unless the result is needed before continuing.
4. Read the log and verify the result before reporting.Read the whole file at its exact version.
How to install
mdr add sadiksaifi/skills/codex-subagent@sha256:23615f70d19d4c03The line at the top of this page pins the label git:20261028.f9baf75, 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.
