## New Features
- Skill metadata can now be defined in `SKILL.toml` (names, descriptions, icons, brand color, default prompt) and surfaced in the app server and TUI (#9125)
- Clients can explicitly disable web search and signal eligibility via a header to align with server-side rollout controls (#9249)
## Bug Fixes
- Accepting an MCP elicitation now sends an empty JSON payload instead of null to satisfy servers expecting content (#9196)
- Input prompt placeholder styling is back to non-italic to avoid terminal rendering issues (#9307)
- Empty paste events no longer trigger clipboard image reads (#9318)
- Unified exec cleans up background processes to prevent late End events after listeners stop (#9304)
## Chores
- Refresh the orchestrator prompt to improve internal routing behavior (#9301)
- Reduce noisy `needs_follow_up` error logging (#9272)
