Calendar Agent: AI-powered schedule management (Tier 2 use case)

[kovtcharov]

Summary

Dedicated calendar management agent that combines browser automation (v0.18.1) with autonomy engine (v0.23.0) for always-on schedule management. The agent proactively manages your calendar — scheduling, reminders, conflict detection, and daily agendas.

Strategic Context

Calendar management is a natural extension of email triage (Tier 1) and daily briefs (Tier 3). Combined with the autonomy engine, this enables:

• Proactive morning agenda briefings
• Automatic conflict detection and rescheduling suggestions
• Meeting prep summaries (pull context from email + docs)
• "Block focus time on my calendar when I have no meetings"

Use Cases Enabled

1. Daily agenda — Morning briefing of today's schedule via Agent UI or messaging
2. Smart scheduling — "Find 30 minutes this week for a 1:1 with Sarah"
3. Conflict detection — Alert when new events overlap with existing ones
4. Meeting prep — Summarize relevant emails/docs before each meeting
5. Focus time — Automatically block deep work hours based on patterns
6. Travel time — Add buffer between in-person meetings

Integration Path

1. Phase 1 (v0.18.1): Browser automation — agent reads/writes Google Calendar via Playwright
2. Phase 2 (v0.23.0): Autonomous — scheduled daily agenda, proactive conflict detection
3. Phase 3 (v0.24.0): Personalized — learns scheduling preferences via memory system

Dependencies

• Implement BrowserToolsMixin with Playwright for web browsing agent #458 — BrowserToolsMixin (Phase 1 — browser-based calendar access)
• Autonomy engine (Phase 2 — scheduled operations)
• Memory system (Phase 3 — preference learning)

Acceptance Criteria

• Agent can read calendar and present daily agenda
• Agent can create/modify/delete events via natural language
• Scheduled daily agenda briefing (morning summary)
• Conflict detection alerts
• All calendar data processed locally

Scope clarification: split between v0.20.0 and v0.23.0

Same pattern as #645 (just commented). The consumer use cases (morning brief, daily companion, calendar awareness) are v0.20.0 critical-path but the full Calendar Agent described here correctly stays in v0.23.0 (depends on autonomy engine).

• v0.20.0 path = calendar awareness as part of the morning-brief skill in the starter pack (Starter skill pack: 10 agentskills.io skills demonstrating the platform #893), powered by a Google Calendar MCP server from the curated catalogue (Agent UI: Curated MCP server catalogue with one-click enable/disable #714)
• v0.23.0 path = this issue — full proactive Calendar Agent with conflict detection, meeting prep, autonomous scheduling

Note: this issue's body references browser-automation work in v0.18.1, but v0.18.1 is now Test & CI Hardening after the recent reorg. The browser automation actually lives in v0.18.2 (#661 web-app workflow + #889 Telegram + the MCP catalogue #714). Worth a body update.
