What it does

Cal Com Automation is an agent skill from davepoon/buildwithclaude. Automate Cal.com tasks via Rube MCP (Composio): manage bookings, check availability, configure webhooks, and handle teams. Always search tools first for current schemas.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering App automation through connectors and Webhooks. It works with Composio. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

When your agent uses it

  • Tasks that involve App automation through connectors
  • Tasks that involve Webhooks

Example prompts

  • “/cal-com-automation”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Manage Bookings
  2. Check Availability
  3. Configure Webhooks
  4. Manage Teams
  5. Organization Management

What it can do on your machine

Read from SKILL.md and the folder at commit 616deb5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • rube.app

    Also links to:

    • composio.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cal Com Automation loads about 1.9k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 800 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cal.com Automation via Rube MCP

Automate Cal.com scheduling operations through Composio's Cal toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/cal

Prerequisites

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

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

  1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
  2. Call RUBE_MANAGE_CONNECTIONS with toolkit cal
  3. If connection is not ACTIVE, follow the returned auth link to complete Cal.com authentication
  4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Manage Bookings

When to use: User wants to list, create, or review bookings

Tool sequence:

  1. CAL_FETCH_ALL_BOOKINGS - List all bookings with filters [Required]
  2. CAL_POST_NEW_BOOKING_REQUEST - Create a new booking [Optional]

Key parameters for listing:

  • status: Filter by booking status ('upcoming', 'recurring', 'past', 'cancelled', 'unconfirmed')
  • afterStart: Filter bookings after this date (ISO 8601)
  • beforeEnd: Filter bookings before this date (ISO 8601)

Key parameters for creation:

  • eventTypeId: Event type ID for the booking
  • start: Booking start time (ISO 8601)
  • end: Booking end time (ISO 8601)
  • name: Attendee name
  • email: Attendee email
  • timeZone: Attendee timezone (IANA format)
  • language: Attendee language code
  • metadata: Additional metadata object

Pitfalls:

  • Date filters use ISO 8601 format with timezone (e.g., '2024-01-15T09:00:00Z')
  • eventTypeId must reference a valid, active event type
  • Booking creation requires matching an available slot; check availability first
  • Time zone must be a valid IANA timezone string (e.g., 'America/New_York')
  • Status filter values are specific strings; invalid values return empty results
2. Check Availability

When to use: User wants to find free/busy times or available booking slots

Tool sequence:

  1. CAL_RETRIEVE_CALENDAR_BUSY_TIMES - Get busy time blocks [Required]
  2. CAL_GET_AVAILABLE_SLOTS_INFO - Get specific available slots [Required]

Key parameters:

  • dateFrom: Start date for availability check (YYYY-MM-DD)
  • dateTo: End date for availability check (YYYY-MM-DD)
  • eventTypeId: Event type to check slots for
  • timeZone: Timezone for the availability response
  • loggedInUsersTz: Timezone of the requesting user

Pitfalls:

  • Busy times show when the user is NOT available
  • Available slots are specific to an event type's duration and configuration
  • Date range should be reasonable (not months in advance) to get accurate results
  • Timezone affects how slots are displayed; always specify explicitly
  • Availability reflects calendar integrations (Google Calendar, Outlook, etc.)
3. Configure Webhooks

When to use: User wants to set up or manage webhook notifications for booking events

Tool sequence:

  1. CAL_RETRIEVE_WEBHOOKS_LIST - List existing webhooks [Required]
  2. CAL_GET_WEBHOOK_BY_ID - Get specific webhook details [Optional]
  3. CAL_UPDATE_WEBHOOK_BY_ID - Update webhook configuration [Optional]
  4. CAL_DELETE_WEBHOOK_BY_ID - Remove a webhook [Optional]

Key parameters:

  • id: Webhook ID for GET/UPDATE/DELETE operations
  • subscriberUrl: Webhook endpoint URL
  • eventTriggers: Array of event types to trigger on
  • active: Whether the webhook is active
  • secret: Webhook signing secret

Pitfalls:

  • Webhook URLs must be publicly accessible HTTPS endpoints
  • Event triggers include: 'BOOKING_CREATED', 'BOOKING_RESCHEDULED', 'BOOKING_CANCELLED', etc.
  • Inactive webhooks do not fire; toggle active to enable/disable
  • Webhook secrets are used for payload signature verification

4. Manage Teams

When to use: User wants to create, view, or manage teams and team event types

Tool sequence:

  1. CAL_GET_TEAMS_LIST - List all teams [Required]
  2. CAL_GET_TEAM_INFORMATION_BY_TEAM_ID - Get specific team details [Optional]
  3. CAL_CREATE_TEAM_IN_ORGANIZATION - Create a new team [Optional]
  4. CAL_RETRIEVE_TEAM_EVENT_TYPES - List event types for a team [Optional]

Key parameters:

  • teamId: Team identifier
  • name: Team name (for creation)
  • slug: URL-friendly team identifier

Pitfalls:

  • Team creation may require organization-level permissions
  • Team event types are separate from personal event types
  • Team slugs must be URL-safe and unique within the organization
5. Organization Management

When to use: User wants to view organization details

Tool sequence:

  1. CAL_GET_ORGANIZATION_ID - Get the organization ID [Required]

Key parameters: (none required)

Pitfalls:

  • Organization ID is needed for team creation and org-level operations
  • Not all Cal.com accounts have organizations; personal plans may return errors

Common Patterns

Booking Creation Flow
1. Call CAL_GET_AVAILABLE_SLOTS_INFO to find open slots
2. Present available times to the user
3. Call CAL_POST_NEW_BOOKING_REQUEST with selected slot
4. Confirm booking creation response
ID Resolution

Team name -> Team ID:

1. Call CAL_GET_TEAMS_LIST
2. Find team by name in response
3. Extract id field
Webhook Setup
1. Call CAL_RETRIEVE_WEBHOOKS_LIST to check existing hooks
2. Create or update webhook with desired triggers
3. Verify webhook fires on test booking

Known Pitfalls

Date/Time Formats:

  • Booking times: ISO 8601 with timezone (e.g., '2024-01-15T09:00:00Z')
  • Availability dates: YYYY-MM-DD format
  • Always specify timezone explicitly to avoid confusion

Event Types:

  • Event type IDs are numeric integers
  • Event types define duration, location, and booking rules
  • Disabled event types cannot accept new bookings

Permissions:

  • Team operations require team membership or admin access
  • Organization operations require org-level permissions
  • Webhook management requires appropriate access level

Rate Limits:

  • Cal.com API has rate limits per API key
  • Implement backoff on 429 responses
