Codex CLI 0.140.0-alpha.9

0.140.0-alpha.8→0.140.0-alpha.9

Patch release that adds internal groundwork for skills tooling and an MCP resource client, along with related data-model refinements.

Under the hood

  • Added a new skills subsystem containing an orchestrator, state management, and tool handlers for listing, reading, and schema operations.
  • Introduced codex-mcp/src/resource_client.rs to support MCP resource interactions.
  • Updated several internal enums and variants (including FileSystemPath, McpServerIdentity, ResourceContent, SandboxPolicyDeserialize, ServerRequest, ThreadItem, and UserInput) to reflect evolving request/response shapes and approval flows.
  • Added the ListArgs data model.

Upgrade notes

No user-visible changes; normal alpha update process applies.
