 # Changelog
 
+## [0.11.16.0] - 2026-03-24 — Cleaner Skill Descriptions + Proactive Opt-Out
+
+### Changed
+
+- **Skill descriptions are now clean and readable.** Removed the ugly "MANUAL TRIGGER ONLY" prefix from every skill description that was wasting 58 characters and causing build errors for Codex integration.
+- **You can now opt out of proactive skill suggestions.** The first time you run any gstack skill, you'll be asked whether you want gstack to suggest skills during your workflow. If you prefer to invoke skills manually, just say no — it's saved as a global setting. You can change your mind anytime with `gstack-config set proactive true/false`.
+
+### Fixed
+
+- **Telemetry source tagging no longer crashes.** Fixed duration guards and source field validation in the telemetry logger so it handles edge cases cleanly instead of erroring.
+
 ## [0.11.15.0] - 2026-03-24 — E2E Test Coverage for Plan Reviews & Codex
