Google Calendar integration for viewing, creating, and managing calendar events.

  • Works in 4 steps: User must create Google Cloud project… → Save client_secret.json to… → Run authentication → …
  • The user asks about their schedule
  • SKILL.md covers Quick Reference, Setup, Tiers and Usage Patterns, plus 6 more sections
  • Runs Python scripts from its folder; calls python

What it does

Gcal Pro is an agent skill from sundial-org/awesome-openclaw-skills. Google Calendar integration for viewing, creating, and managing calendar events. Use when the user asks about their schedule, wants to add/edit/delete events, check availability, or needs a morning brief. Supports natural language like "What's on my calendar tomorrow?" or "Schedule lunch with Alex at noon Friday." Free tier provides read access; Pro tier ($12) adds create/edit/delete and morning briefs.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts and reference files (for example `README.md`, `docs/GOOGLE_CLOUD_SETUP.md` and `references/api-quickref.md`).

It sits in Productivity & Automation. It works with Google Calendar and Python. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.

When your agent uses it

  • The user asks about their schedule
  • Wants to add/edit/delete events
  • Check availability
  • Needs a morning brief

Example prompts

  • “s on my calendar tomorrow?”
  • “Schedule lunch with Alex at noon Friday.”
  • “/gcal-pro”

Requirements

  • Python 3

Workflow steps

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

  1. User must create Google Cloud project and OAuth credentials
  2. Save client_secret.json to ~/.config/gcal-pro/
  3. Run authentication
  4. Browser opens → user grants calendar access → done

What it can do on your machine

Read from SKILL.md and the folder at commit b80cde2. 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

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

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

  • Network

    No URLs in SKILL.md.

    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

Gcal Pro loads about 1.4k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 460 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.2k

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 460 words (~1,435 tokens).

“Manage Google Calendar through natural conversation.”
