Unreleased

Runtime skill support with thread-pinned skills, per-turn skill overrides, and execution-policy enforcement for allowed tools, required tools, tool sequence, and max tool calls.
Dynamic persona and skill loading from local files and remote URLs through AgentDefinitionSource.
Resolved-instructions preview support so host apps can inspect the final compiled instructions for a turn.
Transient request retry/backoff policy support in the Codex responses backend.
Configurable reasoning effort (low, medium, high, xhigh) for gpt-5.4 style thinking control.
Demo app UI for switching thinking level on future requests.

Added CLI-style unauthorized-session recovery so runtime operations can refresh and retry once after auth expiry or invalidation.
Improved the demo app’s skill and Health Coach flows to better show persona, skill, and tool orchestration together.
Expanded README coverage for retries, skills, dynamic definition sources, and reasoning effort configuration.

Stable CodexKit + CodexKitUI runtime surface for iOS agent integration.
ChatGPT auth with .deviceCode and .oauth (localhost loopback callback flow).
Threaded runtime state restore, streaming output handling, and approval-gated tool execution.
Layered persona model (base instructions, thread persona stack, per-turn override).
Text + image user input support and assistant image attachment hydration.
Demo iOS app with:
- dual auth flows
- tool registration and logging
- persona demos
- Health Coach tab with HealthKit integration and proactive AI-generated coaching feedback
- local reminder scheduling

Refactored demo app into smaller Swift files for clearer ownership and readability.
Updated README docs with production setup guidance and end-to-end examples.
