Let users hide skills from the model-facing available catalog through the chat Skills selector while keeping pinned skill injection as a separate mode.
Hidden skills are filtered from skill listing, search, loading, relevant recall, and loaded-skill prompt injection, with chat-level show/hide overrides and persistent default hidden-skill config support.
Add user-configurable timezone and 12/24-hour preferences, then wire them through settings, runtime snapshots, scheduler payloads, wait handling, notifications, backups, memory, plugin metadata, and frontend formatters.
Keep UTC as the boundary for absolute instants while serializing user-facing dates in the configured or browser-resolved timezone. Preserve scheduler wall-clock inputs in the selected timezone, propagate TZ into desktop/runtime process environments, and restart active desktop sessions when the runtime timezone changes.
Cover the risky paths with timezone regression tests for settings normalization, auto and fixed timezone resolution, scheduler round-trips, memory timestamp conversion, and desktop timezone sync.
Add a builtin `a0-setup-cli` skill for guiding host-side A0 connector setup,
and restore the lightweight trigger-word based skill matching flow, which many users asked for.
- add builtin `skills/a0-setup-cli/` with installer-first host setup guidance,
container guardrails, fallback install paths, and example responses
- fix `helpers.skills_cli` so builtin skills under `/skills` are discoverable,
searchable, and validatable
- restore trigger-pattern scoring in runtime `search_skills()`
- re-enable `skills_tool:search` in the current tool flow
- add lightweight lexical relevant-skill recall for the current user message
without reintroducing memory/vector-db skill recall
- update skill prompts to steer the agent toward search/load when requests
match skill trigger phrases
- Extract presets into global presets.yaml; move editor to plugin main screen
- Add project-wide override sync and three-layer permission checks
- Fix embedding change detection, new-chat inheritance, and preset name leak bugs
- Clean up dead imports/params and fix description text
