Free OpenAI Codex CLI Config Generator

An OpenAI Codex CLI config generator creates a ready-to-paste config.toml and launch command for model choice, sandbox mode, approval policy, working directory, profiles, and optional web search.

Configure Codex

Workflow preset

Safety note

OpenAI documents Codex CLI as a local coding agent with approval modes and sandbox controls. Keep destructive access out of shared presets, and reserve never plus danger-full-access for automation hosts you already control.

config.toml

model = "gpt-5.1"
sandbox_mode = "workspace-write"
approval_policy = "on-request"
model_reasoning_effort = "high"

Launch command

codex \
  -m \
  'gpt-5.1' \
  -s \
  workspace-write \
  -a \
  on-request \
  -c \
  'model_reasoning_effort="high"' \
  -C \
  '$PWD' \
  --strict-config \
  'Implement the requested feature and verify it locally.'

Install snippet

export CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
mkdir -p "$CODEX_HOME"
cat > "$CODEX_HOME/config.toml" <<'TOML'
model = "gpt-5.1"
sandbox_mode = "workspace-write"
approval_policy = "on-request"
model_reasoning_effort = "high"
TOML
codex --strict-config --help >/dev/null

How to generate a Codex CLI config

  1. Choose a workflow preset. Pick audit, feature work, CI review, or full automation based on how much file and shell access Codex should have.
  2. Set model and runtime options. Choose a model, reasoning effort, sandbox mode, approval policy, working directory, extra writable folders, and optional web search.
  3. Copy config.toml. Copy the generated TOML into ~/.codex/config.toml or a named profile file in your Codex home directory.
  4. Run the generated command. Use the command preview to start interactive Codex, codex exec, or codex review with matching flags.

Sandbox controls

Compare read-only, workspace-write, and danger-full-access modes before giving Codex file or shell permissions.

Approval policies

Generate interactive, review, and automation presets using untrusted, on-request, or never approval behavior.

Copyable output

Copy config.toml, profile instructions, and terminal commands for interactive Codex, codex exec, or codex review.

Codex CLI config FAQ

What is an OpenAI Codex CLI config generator?

An OpenAI Codex CLI config generator creates a ready-to-paste config.toml and terminal command for model choice, sandbox mode, approval policy, working directory, profiles, and optional web search.

Where does Codex CLI read config.toml from?

Codex CLI reads configuration from the Codex home directory, normally ~/.codex/config.toml. You can also layer a named profile file with the -p flag.

Which Codex sandbox mode should I choose?

Use read-only for audits, workspace-write for normal feature work, and danger-full-access only when you already trust the environment and need unrestricted local commands.

What approval policy is safest for Codex CLI?

The safest interactive default is on-request or untrusted because Codex asks before risky commands. Use never only for automation running in a separately controlled environment.

Does this tool send my Codex config anywhere?

No. The generator runs in your browser, stores preferences in localStorage, and creates copyable TOML and shell snippets without sending the generated config to Tornic.
