## Setup Notes

### Enable Marketplace Auto-Update

### Oracle Skill

The oracle skill requires **Codex CLI** to be installed. Install it and configure the profile below to enable invoking gpt-5.2 (xhigh) for complex reasoning tasks.

Add this profile to your Codex `config.toml`:

```toml
[profiles.oracle]
model = "gpt-5.2"
model_reasoning_effort = "xhigh"
approval_policy = "never"
sandbox_mode = "read-only"

[sandbox_workspace_write]
network_access = true

[features]
web_search_request = true
```

See the [Codex CLI documentation](https://github.com/openai/codex) for setup instructions.
