Outlook Calendar Automation V2

Outlook Calendar Automation via Rube MCP

Overview

This public intake copy packages plugins/antigravity-awesome-skills/skills/outlook-calendar-automation from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Outlook Calendar Automation via Rube MCP Automate Outlook Calendar operations through Composio's Outlook toolkit via Rube MCP.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Prerequisites, Common Patterns, Known Pitfalls, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Automate Outlook Calendar tasks via Rube MCP (Composio): create events, manage attendees, find meeting times, and handle invitations. Always search tools first for current schemas.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Verify Rube MCP is available by confirming RUBESEARCHTOOLS responds
2. Call RUBEMANAGECONNECTIONS with toolkit outlook
3. If connection is not ACTIVE, follow the returned auth link to complete Microsoft OAuth
4. Confirm connection status shows ACTIVE before running any workflows
5. OUTLOOKLISTCALENDARS - List available calendars [Optional]
6. OUTLOOKCALENDARCREATE_EVENT - Create the event [Required]
7. subject: Event title

Imported: Core Workflows

1. Create Calendar Events

When to use: User wants to schedule a new event on their Outlook calendar

Tool sequence:

1. OUTLOOK_LIST_CALENDARS - List available calendars [Optional]
2. OUTLOOK_CALENDAR_CREATE_EVENT - Create the event [Required]

Key parameters:

• subject: Event title
• start_datetime: ISO 8601 start time (e.g., '2025-01-03T10:00:00')
• end_datetime: ISO 8601 end time (must be after start)
• time_zone: IANA or Windows timezone (e.g., 'America/New_York', 'Pacific Standard Time')
• attendees_info: Array of email strings or attendee objects
• body: Event description (plain text or HTML)
• is_html: Set true if body contains HTML
• location: Physical location string
• is_online_meeting: Set true for Teams meeting link
• online_meeting_provider: 'teamsForBusiness' for Teams integration
• show_as: 'free', 'tentative', 'busy', 'oof'

Pitfalls:

• start_datetime must be chronologically before end_datetime
• time_zone is required and must be a valid IANA or Windows timezone name
• Adding attendees can trigger invitation emails immediately
• To generate a Teams meeting link, set BOTH is_online_meeting=true AND>
• user_id defaults to 'me'; use email or UUID for other users' calendars

2. List and Search Events

When to use: User wants to find events on their calendar

Tool sequence:

1. OUTLOOK_GET_MAILBOX_SETTINGS - Get user timezone for accurate queries [Prerequisite]
2. OUTLOOK_LIST_EVENTS - Search events with filters [Required]
3. OUTLOOK_GET_EVENT - Get full details for a specific event [Optional]
4. OUTLOOK_GET_CALENDAR_VIEW - Get events active during a time window [Alternative]

Key parameters:

• filter: OData filter string (e.g., "start/dateTime ge '2024-07-01T00:00:00Z'")
• select: Array of properties to return
• orderby: Sort criteria (e.g., ['start/dateTime desc'])
• top: Results per page (1-999)
• timezone: Display timezone for results
• start_datetime/end_datetime: For CALENDAR_VIEW time window (UTC with Z suffix)

Pitfalls:

• OData filter datetime values require single quotes and Z suffix
• Use 'start/dateTime' for event start filtering, NOT 'receivedDateTime' (that is for emails)
• 'createdDateTime' supports orderby/select but NOT filtering
• Pagination: follow @odata.nextLink until all pages are collected
• CALENDAR_VIEW is better for "what's on my calendar today" queries (includes spanning events)
• LIST_EVENTS is better for keyword/category filtering
• Response events have start/end nested as start.dateTime and end.dateTime

3. Update Events

When to use: User wants to modify an existing calendar event

Tool sequence:

1. OUTLOOK_LIST_EVENTS - Find the event to update [Prerequisite]
2. OUTLOOK_UPDATE_CALENDAR_EVENT - Update the event [Required]

Key parameters:

• event_id: Unique event identifier (from LIST_EVENTS)
• subject: New event title (optional)
• start_datetime/end_datetime: New times (optional)
• time_zone: Timezone for new times
• attendees: Updated attendee list (replaces existing if provided)
• body: Updated description with contentType and content
• location: Updated location

Pitfalls:

• UPDATE merges provided fields with existing event; unspecified fields are preserved
• Providing attendees replaces the ENTIRE attendee list; include all desired attendees
• Providing categories replaces the ENTIRE category list
• Updating times may trigger re-sends to attendees
• event_id is required; obtain from LIST_EVENTS first

4. Delete Events and Decline Invitations

When to use: User wants to remove an event or decline a meeting invitation

Tool sequence:

1. OUTLOOK_DELETE_EVENT - Delete an event [Optional]
2. OUTLOOK_DECLINE_EVENT - Decline a meeting invitation [Optional]

Key parameters:

• event_id: Event to delete or decline
• send_notifications: Send cancellation notices to attendees (default true)
• comment: Reason for declining (for DECLINE_EVENT)
• proposedNewTime: Suggest alternative time when declining

Pitfalls:

• Deletion with send_notifications=true sends cancellation emails
• Declining supports proposing a new time with start/end in ISO 8601 format
• Deleting a recurring event master deletes all occurrences
• sendResponse in DECLINE_EVENT controls whether the organizer is notified

5. Find Available Meeting Times

When to use: User wants to find optimal meeting slots across multiple people

Tool sequence:

1. OUTLOOK_FIND_MEETING_TIMES - Get meeting time suggestions [Required]
2. OUTLOOK_GET_SCHEDULE - Check free/busy for specific people [Alternative]

Key parameters:

• attendees: Array of attendee objects with email and type
• meetingDuration: ISO 8601 duration (e.g., 'PT1H' for 1 hour, 'PT30M' for 30 min)
• timeConstraint: Time slots to search within
• minimumAttendeePercentage: Minimum confidence threshold (0-100)
• Schedules: Email array for GET_SCHEDULE
• StartTime/EndTime: Time window for schedule lookup (max 62 days)

Pitfalls:

• FIND_MEETING_TIMES searches within work hours by default; use activityDomain='unrestricted' for 24/7
• Time constraint time slots require dateTime and timeZone for both start and end
• GET_SCHEDULE period cannot exceed 62 days
• Meeting suggestions respect attendee availability but may return suboptimal times for complex groups

Imported: Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Outlook connection via RUBE_MANAGE_CONNECTIONS with toolkit outlook
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Examples

Example 1: Ask for the upstream workflow directly

Use @outlook-calendar-automation-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @outlook-calendar-automation-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @outlook-calendar-automation-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @outlook-calendar-automation-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills/skills/outlook-calendar-automation, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes

Imported: Quick Reference

Imported: Common Patterns

Event ID Resolution

1. Call OUTLOOK_LIST_EVENTS with time-bound filter
2. Find target event by subject or other criteria
3. Extract event id (e.g., 'AAMkAGI2TAAA=')
4. Use in UPDATE, DELETE, or GET_EVENT calls

OData Filter Syntax for Calendar

Time range filter:

filter: "start/dateTime ge '2024-07-01T00:00:00Z' and start/dateTime le '2024-07-31T23:59:59Z'"

Subject contains:

filter: "contains(subject, 'Project Review')"

Combined:

filter: "contains(subject, 'Review') and categories/any(c:c eq 'Work')"

Timezone Handling

• Get user timezone: OUTLOOK_GET_MAILBOX_SETTINGS with select=['timeZone']
• Use consistent timezone in filter datetime values
• Calendar View requires UTC timestamps with Z suffix
• LIST_EVENTS filter accepts timezone in datetime values

Online Meeting Creation

1. Set is_online_meeting: true
2. Set online_meeting_provider: 'teamsForBusiness'
3. Create event with OUTLOOK_CALENDAR_CREATE_EVENT
4. Teams join link available in response onlineMeeting field
5. Or retrieve via OUTLOOK_GET_EVENT for the full join URL

Imported: Known Pitfalls

DateTime Formats:

• ISO 8601 format required: '2025-01-03T10:00:00'
• Calendar View requires UTC with Z: '2025-01-03T10:00:00Z'
• Filter values need single quotes: "'2025-01-03T00:00:00Z'"
• Timezone mismatches shift event boundaries; always resolve user timezone first

OData Filter Errors:

• 400 Bad Request usually indicates filter syntax issues
• Not all event properties support filtering (createdDateTime does not)
• Retry with adjusted syntax/bounds on 400 errors
• Valid filter fields: start/dateTime, end/dateTime, subject, categories, isAllDay

Attendee Management:

• Adding attendees triggers invitation emails
• Updating attendees replaces the full list; include all desired attendees
• Attendee types: 'required', 'optional', 'resource'
• Calendar delegation affects which calendars are accessible

Response Structure:

• Events nested at response.data.value
• Event times at event.start.dateTime and event.end.dateTime
• Calendar View may nest at data.results[i].response.data.value
• Parse defensively with fallbacks for different nesting levels

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
