Manages Google Calendar from a Telegram chat: lists the schedule, creates and updates events, finds free time and sends daily briefings and reminders.

Asking what is on today's calendar
SKILL.md covers Available MCP Tools, Use Cases, Date/Time Handling and Proactive Calendar Features, plus 1 more section
Calls npx; needs GOOGLE_OAUTH_CREDENTIALS

What it does

The skill uses the Google Calendar MCP tools to list, create, update and delete events and to find free time, and it replies through Telegram. For a question like what is on my calendar it lists the date range and formats times, titles and locations. For new events it parses the title, date, time, duration and location and asks you to confirm anything ambiguous, such as next Thursday, before creating.

Daily briefings combine today's and tomorrow's events and can be sent every morning with the `schedule` tool, and reminders can be scheduled for important meetings. Dates use ISO 8601, the timezone comes from context with Europe/Lisbon as the fallback, and relative dates are converted to exact ones. If the tools are missing, the Google Calendar MCP server is probably not connected, and the user is told to run its auth command with their OAuth credentials file.

When your agent uses it

Asking what is on today's calendar
Adding an event from a chat message
Finding a free slot in the week
Getting a morning briefing of today's and tomorrow's events

Example prompts

“What's on my calendar today?”
“Add lunch with Maria on Friday at noon to my calendar.”
“When am I free on Thursday afternoon?”
“Set up a daily morning briefing of my events.”

Requirements

The Google Calendar MCP server, authenticated with Google OAuth credentials
A Telegram-connected Claude Code session to reply in
Pre-approved tools (allowed-tools): Bash(npx *), Read, Write, mcp__google-calendar__list-events, mcp__google-calendar__create-event, mcp__google-calendar__update-event, mcp__google-calendar__delete-event, mcp__google-calendar__find-free-time, mcp__google-calendar__manage-accounts

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

mcpgoogle-calendarlist-events — list upcoming events
mcpgoogle-calendarcreate-event — create new events
mcpgoogle-calendarupdate-event — modify events
mcpgoogle-calendardelete-event — remove events
mcpgoogle-calendarfind-free-time — check availability

What it can do on your machine

Read from SKILL.md and the folder at commit 688e8fc. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash(npx *)
- Read
- Write
- mcp__google-calendar__list-events
- mcp__google-calendar__create-event
- mcp__google-calendar__update-event
- mcp__google-calendar__delete-event
- mcp__google-calendar__find-free-time
- mcp__google-calendar__manage-accounts
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- GOOGLE_OAUTH_CREDENTIALS
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Google Calendar via Telegram loads about 791 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 310 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~64
When it runs · the whole SKILL.md, loaded when a task matches: ~791

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.
