official OpenAI Codex CLI config.toml model_providers provider table model field configuration reference

💡 Result:

The official **Codex config reference** documents `model_providers.<id>` as a provider table, but does **not** list `model` as a field within that table. It lists `base_url`, `name`, `wire_api`, and authentication and request options. The model is selected separately with the top-level `model` setting; `model_provider` selects the provider ID. ([developers.openai.com](https://developers.openai.com/ja-JP/docs/config-file/config-reference?utm_source=openai))

```toml
model = "your-model"
model_provider = "my-provider"

[model_providers.my-provider]
name = "My Provider"
base_url = "https://example.com/v1"
wire_api = "responses"
env_key = "MY_API_KEY"
```

So, based on the reference, configure the model at the top level—not as `[model_providers.my-provider].model`. Provider settings belong in the user-level `~/.codex/config.toml`; the reference says project-local config ignores `model_provider` and `model_providers`. ([developers.openai.com](https://developers.openai.com/ja-JP/docs/config-file/config-reference?utm_source=openai))

Reset the section when a TOML header has a trailing comment.

For this valid input:

model_provider = "selected"
[model_providers.selected]
[profiles.default] # note
model = "profile-model"

the parser emits:

-c model_providers.selected.model="profile-model"

The Codex config contract defines model as a top-level setting, not a model_providers.<id> field. This can make the auto-naming invocation reject or mis-handle the provider configuration. A provider-prefix filter fix does not remove this exact-section entry.

Review comment at @CLI/CMUXCLI+AutoNaming.swift around lines 200 - 206:
Update the TOML section parsing loop so it removes trailing comments before
checking whether a line is a section header. Set section from the parsed header,
allowing headers such as [profiles.default] # note to replace the previous
section before subsequent keys are emitted.

official OpenAI Codex CLI configuration documentation model_providers provider table unknown keys nested provider names

💡 Result:

The official Codex **Configuration Reference** lists `model_providers.<id>` as a provider table, with supported fields such as `name`, `base_url`, `env_key`, `auth`, and `wire_api`. It says `model_provider` selects a provider by its ID; the ID is the table name, e.g. `[model_providers.my-provider]`. ([developers.openai.com](https://developers.openai.com/codex/config-reference))

For **unknown keys**, the official config schema is clearer: `model_providers` accepts provider entries keyed by ID, but each provider object references `ModelProviderInfo`, which sets `additionalProperties: false`. So unknown fields inside a provider definition are not allowed by the schema. ([developers.openai.com](https://developers.openai.com/codex/config-schema.json))

Nested provider fields are supported when documented/schema-defined—for example, `auth` and its fields, and Bedrock’s `aws.profile` and `aws.region`. The reference does not establish that arbitrary nested keys or arbitrary nested provider names are valid. ([developers.openai.com](https://developers.openai.com/codex/config-reference))

Match the provider section boundary exactly.

hasPrefix("model_providers.\(providerName)") also selects [model_providers.subrouter2] when the selected provider is subrouter. The mapper then emits that entry as model_providers.subrouter.2.*, which violates selected-provider isolation. Codex can reject this malformed provider-table key because unknown fields are not allowed in a provider definition.

🐛 Suggested fix 
-        result.append(contentsOf: providerEntries
-            .filter { $0.section.hasPrefix("model_providers.\(providerName)") }
-            .map {
-                let prefix = "model_providers.\(providerName)"
+        let prefix = "model_providers.\(providerName)"
+        result.append(contentsOf: providerEntries
+            .filter { $0.section == prefix || $0.section.hasPrefix(prefix + ".") }
+            .map {
                 let nestedPath = String($0.section.dropFirst(prefix.count))
                     .trimmingCharacters(in: CharacterSet(charactersIn: "."))

Add regression coverage with both [model_providers.subrouter] and [model_providers.subrouter2], and assert that no subrouter2 value is forwarded.

Update the provider section filter in the AutoNaming result-building flow to
match only the exact provider prefix or sections beginning with that prefix
followed by a dot, so similarly named providers such as subrouter2 are excluded.
Add regression coverage confirming entries from both provider sections are
isolated and subrouter2 values are not forwarded.

OpenAI Codex CLI CODEX_HOME environment variable empty value tilde expansion path convention source

💡 Result:

In the current `main` source:

- **Unset or empty `CODEX_HOME`:** both use the default `$HOME/.codex`. The resolver filters out an empty string, then appends `.codex` to the home directory. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/utils/home-dir/src/lib.rs))
- **Tilde expansion:** the resolver passes a non-empty value directly to `PathBuf::from`; it does not expand `~`. So `CODEX_HOME=~/.codex` is treated as a literal relative path, not as the home directory. This is an inference from the source’s path construction. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/utils/home-dir/src/lib.rs))
- **Explicit path convention:** the source requires that the supplied path already exist and be a directory, then canonicalizes it. Use an expanded path, e.g. `CODEX_HOME="$HOME/.codex"` in a shell. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/utils/home-dir/src/lib.rs))

This describes `main` as viewed on September 29, 2026; behavior in a particular installed CLI version may differ.

Treat an empty CODEX_HOME as unset.

Codex ignores an empty CODEX_HOME and uses $HOME/.codex. This helper instead returns nil, so CodexAutoNamingArguments.build receives no provider or model overrides while the child runs with --ignore-user-config. The summarizer can therefore use Codex's default backend.

Codex does not expand a leading ~. Keep that value unchanged so the reader follows the same path convention as the child. The proposed tilde expansion and absolute-path conversion are not required.
