daemon-backend-codex SKILL.md skillA
daemon-backend-codex from lingtai-ai/lingtai-kernel is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lingtai-ai/lingtai-kernel/daemon-backend-codex@v0.3.1Pins v0.3.1 in mdr.lock. Pin the fingerprint instead.

Nested daemon-cli-backends reference for the Codex daemon backend's flag surface. Read this when a daemon task needs Codex-specific CLI flags (model selection, reasoning effort, config overrides) or the operational core folded in from the retired bash reference guide: install, auth/config, and the Codex-vs-Claude style axis. It routes you to the installed CLI's live help via shell and shows how to translate that help into the generic `backend_options` mechanism. It is not a flag catalog.
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 Daemon Backend — Flag Discovery Entrypoint
The installed CLI's own help is the authority for Codex flags; this page is only
the entrypoint. Conversion rules, key safety, and persistence live in the parent
[`reference/cli-backends/SKILL.md`](../../../SKILL.md).
## Discover flags from the installed CLI
1. Run, in bash: `codex --version`, `codex --help`, and `codex exec --help`.
The daemon backend wraps `codex exec`, so `codex exec --help` is the
relevant flag surface. These are local read-only commands; no session is
started.
2. Translate what you found into `backend_options` with the parent's generic
conversion rules. Nothing Codex-specific is added to that contract here.
## Example: reasoning effort via the generic `config` route
Codex exposes most of its tunables as repeated `-c, --config <key=value>`
overrides (see `codex exec --help` for the key=value syntax). Through
`backend_options`, a list value repeats the flag once per item:
```jsonc
{
"backend": "codex",
"tasks": [{
"task": "Implement and validate the change.",
"tools": [],
"backend_options": {
"config": ["model_reasoning_effort=\"ultra\""]
}
}]
}

How to install
mdr add lingtai-ai/lingtai-kernel/daemon-backend-codex@sha256:257a70726ae7ed4eThe line at the top of this page pins the label v0.3.1, 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.
