Error Message

This produces a diagnostic error (using Tombi LSP):

Code Example

#:schema https://developers.openai.com/codex/config-schema.json

---

[permissions.custom]
extends = ":workspace"

---

In strict mode, `permissions` does not allow "custom" key. Please add `"additionalProperties": true` to the location where it is defined in https://developers.openai.com/codex/config-schema.json, or add `#:tombi schema.strict = false` as a document comment directive at the top of your document, or set `schema.strict = false` in your `tombi.toml`. [table-strict-additional-keys]

---

"PermissionsToml": {
      "additionalProperties": {
        "$ref": "#/definitions/PermissionProfileToml"
      },
    },
    "FilesystemPermissionsToml": {
      "additionalProperties": true,

What is the issue?

When I use Codex config.toml schema:

#:schema https://developers.openai.com/codex/config-schema.json

With permissions block:

[permissions.custom]
extends = ":workspace"

This produces a diagnostic error (using Tombi LSP):

In strict mode, `permissions` does not allow "custom" key. Please add `"additionalProperties": true` to the location where it is defined in https://developers.openai.com/codex/config-schema.json, or add `#:tombi schema.strict = false` as a document comment directive at the top of your document, or set `schema.strict = false` in your `tombi.toml`. [table-strict-additional-keys]

As a consequence, LSP features doesn't work for permissions.* (i.e., completion and diagnostics).

Fix Proposal

Update config.schema.json adding additional properties support for permissions:

    "PermissionsToml": {
      "additionalProperties": {
        "$ref": "#/definitions/PermissionProfileToml"
      },
    },
    "FilesystemPermissionsToml": {
      "additionalProperties": true,
    },

Tested these updates locally and they work for my config.toml.
